Hey guys. I'm new to engine building and know very little. I am buying a 383 stroker complete bottom end. It is bored over .80. I have heard and seen comments on how this isnt a good idea since the cylinder walls are now thinner. I am going to run this motor with the fact in mind I want to be around 320 to 360 hp. I I'll run oversized radiator and electric fans with a custom shroud to help keep this engine cool. I need some ideas on what to run to top end. O have little knowledge on ratios and all that jazz. I am a young blood with a passion to learn so if anyone can give me a sense of direction on how to build this engine to be within around 320 or 350 horse pls help teach me something new.

I'm no engine builder, but I'll give your thread a bump.

Man, you are making me feel my age. The last stroker engine i assembled was in 1999.

I have probably forgotten way too much about small block builds, but one thing I do remember is that starting off with a block bored .080" is a no-no.

If it's bored .80", you wont have any cylinder walls left. :fingersx:

Yes, I know you meant .080". :cheers:

Even at 0.080 he’s barely going to have any cylinder wall left.

Are you sure it’s not 0.030 over?

Traditionally, a 383 is a 350 block bored 0.030 with a 400 crank.

I have a 350 bored 60, 10:1 with an Xe268 cam. Been driving it for 6 years.
