Aluminum vs. Ford iron4V

[marks73]

Seriously. If your looking for "driveability" and more fun than what you have. Moneywise you can't beat 4V CC heads and an aluminum intake with a hotter cam and the correctly tuned carb and distributor. It all depends on what your looking for between 400 and 650 horsepower. Best example I can think of. Ask Xoliex how much money it takes to improve his best time, 1 SECOND!

That makes sense.

Yep how fast you go is determined by how much you will spend on tenths that you will never see/feel on the street
