Re: Overbore and intake valve size
Well,
Just looking at an engine as an air pump.....
With a +.030 overbore the displacement is 308 ci
With a +.060 overbore the displacement is 314 ci
With a +.080 overbore the displacement is 318 ci
If you make 1 hp/ci you would gain 6 hp going to +.060 plus the additional compression.....
Just my thoughts,
PS:
Don't forget to stroke the crankshaft for additional displacement and compression
With a +.060 bore and a .013 stroke you end up with 315 ci
