Re: Why did nhra change the cam and valve spring rule in 1985?
If you check out the rules for IHRA pure stock you find a class thats in line with the original intention of stock eliminator. A person can put together a competitve car for a lot less money. If rules are enforced theres no problem. As far as reliability, while I don't race as much as most, my 327 has been in the car for 5 years without freshening and only minor repairs and still runs the number. Pat
