    Love the video! I currently have an 817 block that is coming together very nice. Eagle rods, KB flattops, Comp Magnum 244 Roller with FloTek 200cc heads. I'm not even sure what kind of monster it is but soon to find out. Balanced also.
    Thanks for sharing the dyno pull and numbers, it gives me hope and ideas! I didnt realize Wartengartner was in Enid OK. I am in SE Kansas.

    I have built about 12 406 engines and they just flat out run. Best bang for buck is this.
    Stock crank with 6 inch rod and hyper flat tops.
    Zero deck to make 11.4 with a 64 cc head.
    Promaxx 215 head
    Flat tappet lunati 247 255 550 530 on a 106
    1.6 1.5 rockers
    Ported vic jr
    850 holly
    1 5/8 headers.
    555 hp at 6200
    540 torque at 4800.
    Same engine with afr 195 and a comp hydro roller 242 248 extreme on a 110 will make 580 hp and 565 torque.

      @dzperformance7360 no problem, I used to build them with the 5.56 rod and I see a good 25 hp just using the 6 inch rod, you can get a good set of rods for cheap now. I have never broke a 400 stock crank even at 600hp and 6800 rpm. As long as the crank has a nice radius they are tough as nails.

    very impressive numbers. I have always liked the Camel Hump heads. there were actually 8 different version of them. the 461, 461X and 462 are identical but the 461X had slightly bigger intake runners as cast. and were used on 327 from 62-67. all had 1.94 intake and 1.50 exhaust valves, except the corvette dual quad, and FI motors that got 2.02/1.60 valves. all of these have not holes in the ends of them for accessories and are for short water pumps and short water pump brackets. the 461X was an over the counter / out the back door head for race teams and not installed on factory cars. the was also a 399X head as well but i don't remember if it had double humps or not.
    there were actually 2 versions of the 291 head 3912291 and 3917291 was used on 327 and 350 and also 302 Z28 Camaro engines. all of these do not have holes in the ends of them for accessories and are for short water pumps and short water pump brackets. the 327 corvette and the 302 z28 got the 2.02/1.60 valves.
    the 168 head was used on 1969 302 engines, and the 1970 LT1 350 engines. the 186 is similar to the 461X head and has the bigger intake runner and it also has the bolt holes in the ends for long water pump style mounting brackets. there were 2 different 492 heads. the 3991492 cast was used in over-the-counter heads with angle plugs, and similar to the 186 head and has the double humps, 3891492 does not have the double humps.
    my personal favorite is the 186 head. but there are stupidly expensive since they only came on 69 302 Z/28 and 1970 Camaro and Corvette LT1 350 cars. and restores want them for numbers matching stuff.
    all that said, every aftermarket aluminum head will out flow the camel humps and the only reason i would use them is if i was restoring a number matching engine or building a marine engine. river/lake and seawater kills aluminum in no time flat. so, hands down Iron for marine use. but even then, there are better iron heads for that. the 906 vortec heads are much better, the old iron bowtie heads are better, the old dart iron eagles are better. i could go on and on about all the better heads. however, if you want the camel hump look on a modern performance head, Trick Flow Specialties has an aluminum replica of the old camel hump heads, and it flow 30 cfm more than the Vortec heads, which are the best flowing factory iron heads. and they are available with or with out the accessory holes on the ends.

      I have the original block 186 heads and intake out of my 70 Z28 Camaro I had in the late 70's. I also picked up a set of bow tie Chevy heads a few years ago for almost nothing. Glad I held onto that stuff. Hopefully will find a project in the next year or two

    • @shadvan9494
      @shadvan9494 2 месяца назад

      It's funny you mentioned a 70 Z28. My current project is a 1971 Camaro SS 396 4 speed car. It's numbers matching, but it is missing a few big ticket items. Like the radiator fan shroud amd the rear sway bar is bent like hit something in the road. Body is dent free, except for a small door ding in the passengers side door. Looking forward to getting back on the road

      The exact answer to your questions no not yet. Just running it on the dyno I enlarge in the holes in the gasket like brodex recommends on their cylinder heads that you cannot get water between the cylinders. But if I was going to drive it on the street I would definitely drill the holes

  • @OneMoreBolt
    @OneMoreBolt 2 месяца назад

    Solid performance. When I saw 461s on a 400 I thought they would choke it out and not have enough flow to make much more than 425hp or so. Your port work definitely paid dividends on this mill. 1200rpm peak to peak is almost perfect for a street strip application and still at a low enough RPM to have decently good street manners. I dig it.

      After looking at your channel a bit, I'm guessing you know a good bit (alot a bit) more about building motors than I do, I know just enough to say dumb things. haha
      Anyway, seeing that you dyno test in Enid I assume you must not be too far from there. If you are interested I'd be interested in talking to you about a motor build for a car I'm trying to get together for drag n drive events. Maybe do some collaboration videos. I'm out of Guthrie. Anyway, just a thought. I like to support other youtubers and currently looking for an engine builder to try and work with.
