440 Build Plan

I don't know what you have already for parts but there is less grinding to install a stroker with chevy journals. Imo the cam is very small. The narrow lsa of 106 will move the torque lower and the stroke will move your torque down as well. It will be a stump puller for sure but your sacrificing the hp on the top end to do it. Your head choice is great but you can go 10 degrees bigger easily with the cam and it wouldn't hardly lope yet ...and stil sound like a stock engine. We did a 4.25 stroker 25 years ago originally used a mp 484 cam w narrow lsa. Stock valves in ported 452 heads. With 3.23s we averaged a best of 23 mpg over 120 mile trip. It loped lightly but we had 20 degrees more duration then the cam listed.
