Rubberman Posted September 23, 2008 Report Share Posted September 23, 2008 OK, everyone excuse my stupidity, but, I gotta guy going to rebuild my L20 out of my 77 620. He has rebuilt many L20 motors but has never done any types of performance modifications and I'm clueless. I plan on getting a 38 weber, header, he said he would be boring it out (to what, I don't know) Is there a performance cam that I can get for it and where? I'm I going in the right direction with this or not? Is there other things I should do or can? I would appreciate anyones input on this. I don't want to change motors. I want to keep the L20 in it, but do what I can to get the most out of it. Thanks. Quote Link to comment
