The LS engines use a gerotor pump that is crank mounted and flows much more oil than the Gen 1 and Gen 2 style cam driven gear pump. With so much more oil flow GM was able to do away with primary main oiling.. Because of cylinder deactivation and variable cam timing system GM had to use this setup on the new style engines. The oil is also thinner on the newer engines. The older style engines need primary main oiling because of reduced oil flow.compared to modern engines. The GM 60 degree V6 engines had many rod bearing failures because of cheap aluminum pumps and non primary main oiling. Oddly enough the only version of this engine to have SBC style primary main oiling was the "race only" version all aluminum 3.0L engine that was NEVER released to the public. In those 2.8, 3.1L, 3.4L, 3.6L and 3.9L engines, they only had two oil galeries. The lifters got the oil first, then the main bearings, then the rod bearings. In performance applications the rod bearing oil would get too hot and thin causing bearing to crank contact causing failure. In the latest iteration of that engine called the high value engine 3.6L and 3.9L. GM replaced the gear pump with a gerotor pump for increased flow. The 3.9L came with a forged crank.
12:13 yes the block is thicker there for the splayed main caps, however just being splay over vertical 4 bolt is stronger due to the angle of the bolts. Think of a tent having tie down ropes at an angle to keep it from swaying under pressure.
Man I would feel a lot better if I had that block! Haha! Nice my man💪🏻 Great move on the pins!!! Friend of mine built an LS he used the stock crank and went with gold star rods and weisco pistons made 1000 on chassis dyno took it to the track and blew up ! Well here the pins were rated at 650 or 750 something like that which I thought was odd because people have pushed stock past that ...
400s are a great engine but they got a bad rap back in the day because GM crippled them with very restrictive heads. They put the same runner head on as the 350 and couple that with a shorter rod they just couldnt get air. Have a couple myself and always loved the torque these can put out with minor upgrades.
@@amandamitchelfrye1603 Man I hope so, I have always loved the 400 SBC ever since a neighbor had one in a 1975 Vette back when I was a young lad. I blame him for planting the bug during my childhood.
Shit the shp blocks can Handel alot more then 650hp i have a 351sbf shp block that is 446 cui and its a nitrous engine that makes North of 1100 hp on bottle
Is any one having trouble with motor mounts ? I just tried to install my new shp 406 in my 81 z28 and I’m having mount issues , it’s mount bound before block seats deep enough to to put both mount bolts in .
But the “Elephant” in the room... Dollar for Dollar how much faster would you be if you had gone LS? Being honest not trying to blow smoke. 🤔🤔🤔 *** I was very hesitant to make the switch mainly because it’s hard to abandon a platform you’re familiar with. But after seeing my friends building $1500-$2000.00 5.3’s making 800+ WHP running low 9’s it becomes enticing! JD
The LS is a great motor and yes an LS is cheaper nowadays for sure. I have just always wanted a 400 CID SBC because they are just a little diffent. Way more LS S10s than 400s for sure.
@@TPVPRO yeah we got guys make 2000+ with the gen2 lt1 factory blocks just wait tell the aftermarket block gets here. Everyone wants to ack like the ls is so much better. You put a set of good 12begree head on that 400 probably 10 different heads that fit that and it will make 1100 na. I believe mbe has a dart ls7 head that can do that and mast canted valve heads may but thats it as far as I know.
@@michaelstoker6710 those stock blocks were all that was available. 40 years ago. I ran many two bolt main engines with pink rods ant trw pistons and cast cranks at the 500-600 hp levels. Maintenance levels were higher and we lost an engine or two, but it can be done. The ls platform in stock trim will sustain 1000 hp with just adding ring gap, cam and a turbo. Can’t do that with a stock 350 or 400. Can they be built to take the hp? Sure they can. Just add a $3500 crank and rods and pistons and add another sum for a set of heads to support the hp. That’s the difference between the ls and small block. Nothing wrong with either setup. Pick your block and build her up. Builders choice. Neither is wrong. Both are good picks.
I have a dart shp block, I got the bottom end sorted but having a hard time buying a cam. What gen am I buying for? Am I looking under the gen 1 chevy motors or am I looking under the gen 2?
was hoping this was going to be the pro block as i have one on order and is due to be shipped to the uk this week, im struggling to find correct lifters etc as the pro block runs the .904 lifter bore and bigblock cam

@@jonathanlawson4667 1986 was the first year for roller lifter provision blocks. The 305s in the GM v8s had it in 1986 although they were still flat tappet in a lot of them. I had an 86 Grand Prix with the roller lifter block. it was 1987 in 350 blocks I believe.

Man, I need to stop saying "You Know"! Gosh darn filler words. 😆 RUclips is great at pointing out all your flaws.
Perhaps the most compelling reason for a modern block is... sizing up lifter bore diameter. Lots of goodness opens up.

😆 Chris Elliott made that movie great!
I had to replace one pair of Howards lifters on my DART SHP block and I only had to pull the intake. The lifters pulled out easily.
Very helpful I'm thinking about building a boosted 400 . I boosted my 350 2 bolt and it took it like a champ

what were the minor upgrades that made the differences .just picked up a 400 pretty stock
Got a DART SHP block 427ci 1000hp procharged in a 92s10 also have a94ss s10 with a 383ci 880 Chevrolet Block as well.
Great video mang! I'm building a roller sbc for my dad and your details help me out alot.
I found you both funny and informative, thanks.
I can't be the only person who wished he had left the lifters in when he rolled the engine over.......KMFNB
If the lifter fails you have to pull the whole engine for a rebuild. So going the extra mile to sneak them past the heads when building is pointless.
I just finally got me a SHP block. I got the 4.00 bore version gonna build a 396
Factory roller blocks were from 88 - 02
Whoa. What. Did you just say while holding your flashlight " lookin all up in the hiney hiney hole".
Nice comparison . Now get them brownies in the oven. Whats your favorite brand? Wallnuts or pecans. Milk is nitrous to a kickass brownie brhu
Hey on your cometic gaskets did you go with the pocket bore style like the 5272-045?
I have seen guys in Mooresville run 900hp on them shp blocks
This one should be around 800 crank on the kit.

You can't get a one piece seal block with a 4.125 bore. The one you show a screen grab of has a 4.00 bore.
Sucks dart, world products and/or Brodix hasn't made an aftermarket big bore lt1 block.
What water pump are you using?
What brand is the oil pan.. Do you have a part number? Thanks
A factory 4 bolt 350 block is very strong. A 4 bolt 400 is a little weaker though.
Yeah I have seen them take some power.
What stud kit is that? I couldn't find one with the standoffs?
1979 was the last year for gen 1 driver side dip stick started passenger side in 1980
I have a 377 using a shp sbc block. What starter and flexplate should I use the trans is a 700r4. Thanks

Your wrong about the heads having to come off to get .300 taller lifters out ,I have one and I can get them out without having to take head off.

It will take a Gen 1 or Gen 2 step nose cam.
87 and newer blocks I believe
How much power can the shp block support?
Do you have the info on the oil pan you used, I'm using the same setup
The SHP right? Call up CNC Motorsports that is where I ordered mine they know what pan to use on a S10.
KEVKO 1073RH
I would definitely have the shop machine 300 off the lifter bosses.
No. If a lifter takes a dump you're rebuilding anyways.
was hoping this was going to be the pro block as i have one on order and is due to be shipped to the uk this week, im struggling to find correct lifters etc as the pro block runs the .904 lifter bore and bigblock cam
