Your combo cannot affect anything other than that same engine combo. If your combo has different heads, valve sizes, etc, then it doesn't affect combos that don't have the same specs. So, if your combo has 2.07"/1.725" valves and oval port heads, it will not affect a combo with 2.195" and 1.725" valves and rectangle ports. |

That's the way they say it works. For the 4.3 Chevy tbi engines they factor flat tappet cams, roller tappet cams, 108 wheelbase, 117 wheelbase, 430 lift cams, stock lift cams, cars or trucks together. All are considered the same engine family and body style.

Re: NHRA hp updates
What effect would bringing back the factory valve spring rule have?
Would this not simplify tech and negate some of the advantage found in cylinder head and intake advancement? |
