Reading the "How to rebuild your SB Ford" book, I read the stock camshaft has a .231" lift. My question is what would be a reasonable step up using all other stock valve train components?
The vehicle is a 49 F1, with a 1974 302 2V/C4 out of an Econoline. The block is currently at the machine shop and will be bored oversize .030". Otherwise, stock dimensions.
I'm looking at .262" to .275"? Any help.
You could swap for a 351W cam without changing your stock componants. It has .2600" lift at the cam. If you use a windsor cam you MUST fire the motor like the Windsor.
The 302 I have in my truck now is bored .040" over, ported windsor heads ('89) and a 302 cam with the same lift as the 351W.
Otherwise the motor is bone stock with a 2150 2V carb and I average about 20 MPG (imp gallon).
You can go up to .320" lobe height without crashing your stock springs. With the stock 1.6 rocker ratio, that comes out to a .512" lift. What you want to do with your lift should be fine.
