340 tune up

Have to agree with post #13. The 71 340 was probably the best small block package ever produced. Almost everything is heavy duty to last hundreds of thousands of miles. It had the best intake, Carb, heads, rockers, springs, double roller timing set. My 71 340 was still breaking into the 13's with 100,000 miles on it.

I don't disagree with this statement at all, but sometimes things are not what they seem. The 71 340 that came in my car turned out to still be standard bore with the high compression pistons and 2.02 J-heads. BUT, it had a forged 318 crank in it.:wtf: I doubt it was properly balanced but it still ran pretty respectfully. That car had a lot wrong with it as I found out later, so I'm not surprised about the crank.
