355?
355? a 350 bored 30 over is a 355 correct? what exactly is gained from going to a 355 from a 350, other than 5ci. Is there a significant power difference? just trying to decide if its worth it
If you do things like tight quench, lighter rotating assembly, higher compression, low tension rings etc, it can be worth a good bit.
Just overbore a block and slap an engine together from that and you wont gain much.

bores look pretty good. i had just planned on getting new pistons and figured for $90 i could have it bored, but if i can reuse my stock pistons that will save me a couple hundred bucks. does anybody see a problem with reusing the stock pistons?

lol i know. im not that dumb
i was meaning just skip out on boring it totally. i just figured getting new pistons i might as well bore it b/c pistons are the same price and its only $90 to have it bored Trending Topics

a 6" rod 355 has one of the best piston to rod ratio's of all the SBC motors..... My old 355 with a 6" eagle h-beam, stock crank, SRP forged pistons with stage II heads, ported manifold, and a 236/242 hydraulic roller (and pretty much all the bolt ons) made 437 RWHP (about 500 at the flywheel) for a reasonably cheap total cost..... think i might have had about 7500 bucks in that motor.....
went 10.40@131 on a one fiddy shot too....
355's can be animals if built right with a good combo of parts......

what is stock rod length? to change rod length does anything have to be machined or is it just swap new rods/pistons in place of stock? excuse my ignorance. this is my first build
