ok so i have a 383 crank and a 305 and im going to stroke the 305 with the 383 crank i know that you have to have special 383 pistons for a 383 stroker, but can you run the cast 305 pistons and 5.7 rods or do you have to have the 400 rods?
I would have to agree and go out and get you a 350 but the thing about it not performing I would have to disagree. anything under a 4 inch bore wont perform? Are you crazy? There are *** loads of motor with under 4 inch bores which are screamers! If Im not mistaken Im pretty sure they sell stroker kits for that 305. That motor will have lots of power. Not as much as a stroked 350 would but it wouldnt be a POS either.killerformula said:will probably have its butt handed to it by a good running 327 any day of the week. Anything smaller than a 4 inch bore isn't goign to perform, and you're not going to be able to put very big valves in it either-

wow so your contradicting your arguement in the other thread about BBskillerformula said:yes, but the latemodel vettes also use different heads and valvetrain equipment to do that. Furthermore, their bore is JUST under 4 inches if I remember. Its widely accepted that motors with smaller bores aren't usually used for performance applications. SImilarly built, a 302 ford and a 305 chevy, the 302 will whip the pants off it. It can spin up higher because of its short stroke. 305's are also further limited by their bores because they can only use valves that are so big (don't think they can use 2.02) because the valves hit the walls of the bores.
So saying that motors with smaller bores don't generally perform, is a valid comment.

Dude, you're totally lost. An LSI motor is a motor using the latest of today's technology to make its power. It has fuel injection, computer designed heads, computer designed timing and injection pulses and roller valvetrain. THe bore is like 3.9x.badazz81z28 said:wow so your contradicting your arguement in the other thread about BBs
FYI a 305 was built in its time for smog reasons. and its bore is just under 4 inches also
Why waste money stroking a 305?badazz81z28 said:I would have to agree and go out and get you a 350 but the thing about it not performing I would have to disagree. anything under a 4 inch bore wont perform?

you would be happier with a 383
You shouldnt rate a motor by the bore size. I guess all the late model car engines like the vettes sucks because the bore is under 4 inches. the LT1, LS1. LS2 and the LS6 I believe are all 3 and some change
Yep, you're wrong BOTH times. You only get 267 cubic inches (I am assuming you mean a 283 crank) and the small (3.766" @ .030" over) bore is way too small compared to the 302 bore.455c-10 said:if i am not mistaken (which i may be) if you bore the 305.030 over or maybe it is .060 and drop a 289 crank in it you can get about the performance of the chevy 302 (all of this i was told by a co-worker and i dont know his credibility but he is a chevy genius.)

why the hell did that come out twice? and if i am wrong on my previous post please correct me
