340 or 408?
there is so many ways to achieve 500-550 hp builds with the parts today.
for years i had 4'' and 4.125'' strokers. then i switched to smaller cubic inch engines. no real reason other then i buy most stuff used. i now have a 3.875'' stroke W8 engine that will be ready for next year. again i bought it all used, only way i can afford this expensive obsession.
