Re: 1971 Buick 455 GS F/SA G/SA Build
Just throwing this out there...I see you're testing at 600rpm per sec (which is standard) did you (or would you consider) dynoing at 300rpm/sec? The reason I ask is it has a heavy rotating assembly and a super steep gear might actually slow it down as too much torque wasted spinning up the heavy internals?
Like I said, just throwing it out there....food for thought as it were. |

In stock your not suppose to be able to do anything to the heads and intake besides a valve job right? although judging from your other post and that you seem to have a in house dyno and who knows what other equipment your probably perfectly capable of altering that to your advantage.

Different valve angles and seat width effect flow, and that's just as two examples of what he meant by "work on the heads". There are many more legal things to do before resorting to "port the heads and cover it up" as you're insinuating. Uncalled for imho, there are a lot of people with a lot of equipment, doesn't mean they must be cheating because they have fancy tools. |

Just wondering where you got the car? I ran the same combo in the past I have a good set of 71 heads TA SS valves with Poston springs off the car along with a few other parts. I am located in Texas now formally Va.
