I want to add some grunt to my lil 307. I know I'm gonna catch hell for wanting to keep the same engine instead of swapping to some other engine, but that's what's gonna happen.
I want to add a 3.75" stroke crank from Summit and the 400 SBC 5.565" rods. This will make it a 360 (359) cubic inch. The only problem is the available pistons will be .070 out of the hole. I can get thicker head gaskets or mill my pistons.
Ready......GO!!!
