I know there is no replacement for displacement.
Heard a lot about the the 352 or 377. Haven't seen one in several years.

Anyone have any input as per useage, power, etc. besides NASCAR?

Certainly the 383 is easier to build, and readily available.

thanks, :welcome:

If I had a good 400 block laying around, I'd try the 352, just so I could say I had a Chevy 352. And also it'd get this dang 307 crank out from under my feet.

Wonder if I could change my fender emblems to say 352???

377"

Yes, I have one in a boat, its a 4 bolt with a CROWER (0024200 cam, 9:5-1 compression, RPM Air gap, 750 Eldebrock, Mallory dist., MSD 6A, early FI. heads that are port matched, bowls and combustion chambers cleaned up and polished, 1:6 roller tipped rockers, and balanced... This motor is brand new, so don't yet know how well it will perform, but it feels good and planes instantly in initial runs to put some time on it...but I have a friend with a 1970 Vette roadster, who built one with a 4-71 blower... IT HAULED !!! ..I understand the advantage is that they will rev due to the shorter stroke, that is why I used it because I am looking for mid range to top end as I can't use the bottom end due to prop size limitations (tire size).... But if you use a blower or NOS you MUST o- ring the block or heads !!!

For your main spacers use a set of 400 .010 bearing and set your 350 mains over them works as good as the aftermarket spacers or the high dollar speical mian bearings.

I had a 3.295 stroke 4.155 bore 358 (made 608 hp @7900 RPM, 460 ft lbs). I really dont see any benefit to a motor like this in a drag or street car. It ran well for the size, but it would have been faster and more fun to drive if it were a 406. On top of the fact that the 406 would have been faster, it would have been more reliable in that the max RPM would have been less, and there would have been less of a tendency for valvetrain problems.

Back in the 60's, i had a friend that ran a 55 chev and it ran 10.30 @ 130 on a small block that was a 352" HILBORN injected chev, i know it was stroked with a REATH AUTOMOTIVE" crank ...thats all i remember

Nothing speacial about the pistons. Most piston makers supply them. This is the same piston that you use on a 400rebuild if you're using the shorter 5.565" factory 400 rods and 3.75" 400 crank.

3.48" crank 5.7" rods

3.75" crank 5.565" rods piston same same :D
cubes figured with .030 overbore

377 is 400 block and 350 crank, 3.48
352 is 400 block and 327 crank, 3.25
325 is 400 block and 283/302 crank, 3.00

I keep wondering, Mopar favored short stokes for their popular engines, and still get raves for muscle power. The new 383/400 was 3.38 stroke.
