Thread: blown 383 stroker

Tweet

Make sure that you can keep your compression at 8.5 to 1, so you will be looking at dish pistons, you will probably want to pre assemble everything before sending all parts away to be balanced

I am building up a 383 bown stroker, and the main issue I am finding is getting heads with a big enough chamber to keep the compression down. Looking at carving out the combustion chambers on some stock 76 cc heads to increase chamber capacity.

i have been looking into this also. so i need low compression. dont blower motors need a special cam also.

Yes. Most manufacturers have blower grinds. They have lobe centers of between 112-114 degrees so the amount of overlap is reduced to avoid bleeding off boost.
