deMideon Posted February 11, 2004 Share Posted February 11, 2004 If you are rebuilding it or building a stroker... it's very easy to get a new crank and have it internally balanced. I am building a 377ci (destroked 400) and that's what I did. Gives you a lot better choices. Quote Link to comment Share on other sites More sharing options...

deMideon Posted February 11, 2004 Share Posted February 11, 2004 I am building it to top out at about 6500 max. I have learned from being on this board that I would have been better off doing a stroked 400 vs destroking. I really don't gain as much as I thought. But, it will still put out about 450hp in a reliable streetable engine! I was where you are at with the L28, I had 13:1 venolia pistons, polished ported head... etc etc... kinda fun to drive but just not real streetable or reliable. So that's why I am doing the sbc.
