I've got the Eagle all forged 347 stroker kit, a machined 302, and a billet steel flywheel. Nothing assembled yet. My goal was low budget power. Now I'm starting to think before going any further $ wise, I should ebay that stuff and go with a stroked windsor (393). Anyone else been in this dilemma?
The 347 will give me at max 375-400 hp. The 393 - maybe closer to 500.
Would the 347 beat the windsor on a road course? Is it incorrect to think the 347 would wind up quicker and be zippier?
