So I bent a shift fork.. and wanna make her faster when we tear it down... it's a longrod stock stroke 370 dune ported on alky now... If I go to a 4 mill or 7 mill maybe even 10mill can I use those jugs or do I have to start over with a stock set?? I do have a stock virgin set that just needs a bore. Is it even worth building a big stock cylinder motor anymore? What about the athena cylinders? Anybody got anything good to say about those? Have a billet badket, lockout, override, would anything else need to be beefed up to handle the power? I have 38mm alky carbs, big bore cpis, I'd like to still use the same carbs/pipes possibly, let me know thanks
