    Way back in 1970, a childhood friend bought first car. It was a Swinger 340. His brother (another childhood friend) still owns that still gorgeous 340. As neither knew how to drive stick, I drove it home from the dealer.
    That car was incredibly fast. Turns out it had a special cam in it.
    There is a high performance 360 in it now, but the original 340 could be put back in.
    Fortunately for that car, both of the brothers are fabulous mechanics and has been in a heated garage virtually all its life.
    I forgot to add it was a medium blue with a white vinyl top. The vinyl top was removed a few years back and the car is now solid blue.
    What is hard to me to believe, we've known each other for 70 years. We were under 5 when we met.

Good Gawd, that car was fast, and so much fun. Been a Mopar fan since i was a kid in the late 70's (79-80) and your channel is a real treat, Jamie.

    I remember seeing a tube chassis 68 Roadrunner back in the mid 90s with a "318", but it wasn't a production based 318, dont think it even had 318 cubes, believe it was built on one of these R blocks, had a single 4-barrel 1050 Dominator on what appeared to be a highly modified Strip Dominator intake or something like it with spacers. Dont know what kind of heads it had on it, but there were B-1 decals on the car. And B-1 valvecovers. It was making well over 750+hp NA and turning upwards of 10,000rpm. Ran low 9.00s in the 1/4 at 150+mph. I was impressed and I'm a GM engine builder. Car looked mean as hell too, Dark Maroon with Cragar Supertricks, 15x3/15x15 combo. Sat like a Pro Stocker. Strut front suspension and narrowed DANA 60 on a 4-link out back. Car obviously didn't weigh shit. But it was a real steel Roadrunner body. That engine was something else. Definitely serious. Dont know the bore & stroke on it, but it had a bigger bore like 4.125 and a real short stroke Moldex crank. Believe dude said it was a NASCAR block, but built for drag racing. Only one I've ever seen up close and I've seen thousands of racing engines for over 50yrs.

    • @jaymoe5.7
      @jaymoe5.7 11 дней назад

      those R blocks came in a variety of combinations, they were the successor of the "X" blocks which I believe came in two sizes, the 318 or the 340. The one you're talking about could very well have been an X block. But these R blocks came in multiple variations, and you could get them with either a 48 degree or 59 degree lifter angle. The most common of the blocks I believe is the R3 340 59 degree block, but Nascar R5's with the P7 heads pop up forsale fairly regularly. These blocks haven't been made in quite some time now, but there's new reproduction R3 blocks being made by Ritter racing. These engines have a ton of potential, there's a guy here on youtube named Brett Miller that builds some incredible small blocks! He regularly gets these engines to make over 1000hp N/A and turn over 9000rpm! Go check out his channel for some crazy small block Mopars haha.

    The early W-2 heads were actually cast by Chrysler. Later ones were contracted out. I bought a pair of W-2 heads when they first came out. The long W-2 valves were extremely expensive, so I turned the rocker shaft pedestals 90 degrees, keeping the beveled corner in the same location by turning them around. I machined new bolt holes in the undrilled sides. This lowered the rocker shafts, so I could use standard length 340 valves, with the W-2 rocker shaft pedestals. I think the bottom bolt holes were maybe larger in diameter than the top bolt holes, but it's been a long time, so I'm not certain. Originally W-2 intake manifolds were made by Holley and were exclusively available through Direct Connection. I used the water heated Street intake manifold, on a 0.060" over pre-1975 360, for 371 cubic inches.

    If I'm not mistaken, that block was meant to be used as a 302 ci for IMSA/IROC racing. There was a special AAR head with W2 style oval ports. They turned 9200 all day long without complaining.

    • @stevehicks8944
      @stevehicks8944 14 дней назад +2

      IROC didn’t exist until the late 1970s. “E” body production ended in 1974. This is a product of Chrysler’s new emphasis on NASCAR in the 1990s.

    • @edwardhegarty750
      @edwardhegarty750 14 дней назад +7

      More likely it was for Trans-Am racing. Keeping the big bore, big vales, and making the already short stroke even shorter for the 302 CID race engine makes sense. As does the revised lifter angle and improved geometry in the rest of the valvetrain. Trans-Am rules required every part used on the car to have a factory part number.

    • @TheZl9000

  • @raysmopar1

    You absolutely can use those W-2s on that block. The rockers will come just barely through the intake surface. There’s tons of pictures online look up 59° heads on a 48° block W fives and W-2s work great.
    Chevy rods work amazing 6 inch rods. If you need any parts for that, let me know. I have plenty.

    So being an R block and not an R1 , you have a block that is one of the ones casted for the 94 Nascar truck series , the 9.2 dh block was designed to use either 3.25 stroke ,6.125 c to c rods and stock 340 Pin height(.02 proud) or 3.31 stroke, 6.20 C to C rods and 1.34 Pin height, the best "roundy round combo was 4.04x3.48 gave you 357ci , use 6.25 rods and the piston pin height was 1.20/1.21 depending on W2 vs W5 head ..(you can use 59 Degree heads on the R block with the right lifters, Some offset left , some off set right, some center) my dad runs a R-block build in a 72 D100 4x2 , 4.10 bore 3.795 stroke, 400CI , rods are 6.25, Pistons have a 1.05 Pin height and were made by Gibtec , heads are W2 , with a spacer to take up the difference from head to Intake, intake manifold is the Mopar 420, Cam is 640/640 260/260@ .050 , 106 LSA , 720hp on Pump gas.....yes 93 oct , truck weighs 3350 race weight, and runs 9.90s low 10s at 138MPH , has a t56 in it and 4.88 gears.

    Now, I’d be in your boat. I don’t want the fancy expensive racing stuff, but I still would choose a decent 340 over the more likely 360 I’m eventually going to settle for.

My 383 would bury the 150 speedo.

I'll stick with the '72 340 core I got, cheaper to come by and barebones so I can go to a roller lifter conversion and a higher lift cam (yes I know some work will need to be done for the roller mod like machining for the lifter bore).

      All you really need to make that late 440 awesome is a set of good aftermarket pistons that are taller to raise the compression ratio, a cam and lifters, and matched valve springs. You can take that much farther with porting, upgrading intake and carb, headers, and more if you’d like. I built a spankin’ 440 a while back and did a couple videos on it. But JustMoparJoe has lots of great big block Mopar builds on his channel, so I highly recommend you check him out if you haven’t yet.

    I believe Chrysler built a lot of these for the Petty truck team’s racing program in the 90’s. I think the R blocks come in a 9.0, 9.2 and 9.6” deck heights and in 48 and 59 degree tappet. These engines were also used in the IROC series Dodge Daytona’s and Avengers.

    • @DeadDodgeGarage
      @DeadDodgeGarage  15 дней назад +2

      Right, I read about the Petty connection earlier. While I knew the Daytona became the IROC car after the Camaro, I had to do some research and see what those were like. In the beginning at least, they were using the similar X block, at 355 CI. Looking at these sweet machines, I’m disappointed we didn’t have comparable road going cars - even with mild Magnum V8s, we’d be having a hell of a time building them now.

    I had a 1970 Roadrunner. It was a state patrol car! It had a 3 speed transmission, coils around the shocks, 318 engine, two barrel carb, and 2.96 rear end. I got it because cylinder 7 had a burn exhaust valve! No dill spots on the ceiling! I went in and did 3 angles on the valves and put it back together! About 6 months, I went did a 340 torker, 625 carter carb, even headers, twin exhaust, 4 speed, and retimed the distributor. The torker had 1/4 inch bigger on one side of the intake. It was powerful! It could on a stop, in 4 gear, to speeds greater than 147 mph. I got 16 mpg with the 2 barrel, and got 34 mpg with a 4 barrel! It went 296 miles and came back with 3 mountain ranges and there was a 1/4 of a tank remaining! It had a 6000 rpm and the valves floated at 6500. I drag raced it and got 124 MPH at 13.3 and never put it into 4 gear! It was kind of slow getting started, but a 3000 RPM it took off!

    I’m fairly sure that they came from the MP with a 3.91 bore. I also think that you could get the factory and straight lifter bores. I looked into getting one in the early 90’s when I was racing a H/SA 340 Demon, but they were heavier than a stock block that was filled with hard block

    • @DeadDodgeGarage
      @DeadDodgeGarage  16 дней назад +2

      Yes, as I understand, there are smaller bore versions. Believe this one is stock 340 bore, but didn’t have a way to verify that handy. And I fully expected this shorter block to be lighter, until I noticed all of that extra beef! They’re seriously chunky.

    I saw one of these blocks at a machine shop I use. I was waiting for him to do some little job and roamed around looking at some of the strange engine blocks he had. I saw what I thought was an old Poly block 318 (the front of those R blocks looks similar) so I asked him what he was doing with the 318 poly. He informed me about what it was. Closer inspection revealed all the differences between that block & a typical LA block. And the strange engines he works on? A LaSalle V-8, Pontiac OHC inline 6 (mid 60s), a couple of Plymouth flathead 6 engines one of which was so old that the lower cylinder outline could be seen on the lower part of the block. One of them had a cylinder liner mishap (cracked the block when installing the liner) and he said that he had a fix all figured out. Then there was the motorcycle cylinder heads he was working on. Ancient & I can't remember what he said they were for. Looked like something out of the 30s. Always something interesting going on. Now about the lifter angle on the LA engines. The 273, 318, 340, 360 engine block design started way back in 1956 with the Plymouth Polysphere head 277 engine. It was developed first as a 277 then 303 then 318 then as a 326 (one year for Dodge) and dropped in 1966 when the LA engine came about. They basically designed a wedge cylinder head for the 318 poly. That original 277 poly shouldn't be confused with the Dodge/ DeSoto poly engines, completely different critters with few internal dimensions being the same. Those engines ranged in size from 270 to 325 ci. The poly 318 & the LA 318 block designs are the same, some bore, same stroke, same crank dimensions, same rod dimensions, same oiling holes for the rockers. Differences: Cylinder head locating pins are in different locations & the poly block has oil drainback holes at the rear of the block. Great video on the r block, I had no idea about the differences.Thanks.

    • @DeadDodgeGarage
      @DeadDodgeGarage  10 дней назад

      Sorry, but the lineage of the “Plymouth” V8 - the “A” engine that ultimately ended up at 318 CI, eventually used across the board at Chrysler, and replaced by the 318 LA - begins with the DeSoto Hemi in 1952. There was no “DeSoto” Poly in the mid 50s like Dodge and Chrysler had, and DeSoto and Dodge Hemis are different designs with different dimensions.
      Although the two are by no means the same, the bottom end of the *short deck* DeSoto Hemi formed the basis of the A series, which in turn formed the basis of the LA series. Compare the valley area of an LA to a DeSoto Hemi. The castings are almost identical, except for the large oval holes opened in the cam tunnel of the later block. They have the same reinforcing stands at the front and rear. They have the same shape at the front passenger corner of the valley. They have similar oil drain openings, with a couple extra in the DeSoto. And they have nearly identical lifter bores - although the flat areas with small holes were omitted from the casting. When I say that the lifter angle originates with the DeSoto Hemi, this is what I mean. It is the oldest ancestor of this engine.
      Also, I am *well* versed in the similarities and differences between the Poly/A engine and the LA. I have dedicated a good bit of screen time to discussing them over the years. Thanks!

    • @larryhutchens7593
      @larryhutchens7593 10 дней назад

      @@DeadDodgeGarage Technically all the engines with the dist in the rear are referred to as A engines by Chrysler, at least some of their manuals use that term. And they never used the term hemi or polysphere in Chrysler manuals, they were referred to as double rocker shaft engines & single rocker shaft engines. And the similarities between the poly 318 & La 318? I have a 318 poly that I rebuilt using LA timing chain, oil pump, crankshaft & rods. The reason for using the LA cast crank: I couldn't find anyone locally who would rebuild the rods with the full floating pins. Race shops would but kinda spendy. I wasn't aware that DeSoto only had the hemi, it must have been Chryslers that I saw with them way back when.

    • @larryhutchens7593
      @larryhutchens7593 10 дней назад

      @@DeadDodgeGarage Sorry, I'm gonna stick with the 277 Plymouth theory. The DeSoto specs don't match much of anything with the 318. Block is shorter (4.3125 for the 341 vs 4.5 for the 318 bore center) , 341 is nearly square B vs S, 318 is over square. Crankshaft rod diameters different. As for the lifters I know that the 325 Dodge uses the same diameter as the 318 poly & the 318 LA. I'm in the process of converting my poly engine to hyd, I still need to change the oil groove for them to work. And the 57 DeSoto used the 325 dodge poly engine called the Firesweep. I thought I had seen a couple of those things in salvage yards way back when they were still around. I have rebuilt both the Dodge 270 & 325 engines. On the 325 I converted a poly engine to hemi using a set of D-500 solid lifter heads. Easy to do with the right parts. Dodge & DeSoto both started out with a small bore engine, raised the block to increase stroke & ended up with a very small bore engine that limited the valve size. If you want to believe the DeSoto thing that's OK but I'm going another direction.

    The cool thing about the basic small block architecture is that there is enough room in the bottom to make it a 440. {4.125" stroke with a 400 Chevy sized piston =439 ci} The downside is that there isn't enough room between the pushrods for port volume to decently feed it, plus cyl wall thickness to fit the Chevy piston. With the right R block as a basis a small block 440 would be a hoot on Saturday night and the vast majority of off branders wouldn't know the difference. "It's just a little 318 stroked to 390 with deccnt heads...... but it goes ok I guess. The small bore kinda limits the valve size."
