I just finished a 512 stroked 440 for a friend and it runs smooth with lots of power, He kept my budget tight.. I used a 440 Source stroker kit their Comp cam with 525 lift 440 source stealth heads ( wanted to use indy''s but not in the budget) new stamped steel rocker arms, Sam at TTI suggested 1 7/8 headers with a 3 inch exhaust, Holley 850 w/ vacuum secondaries and a Holley street dominator intake that WILL clear a stock 68 Satellite hood. I have built a bunch of strokers This combo really works well and is super streetable on pump gas
