Does anyone know in what class this car would run in PCA club racing.
Approximately 320 hp, 2275 lps, 3.4 liters, 1971? Is there many people running in this class?

Thanks,

Stephan

Based on your current weight and engine displacement you would run in GT3, S on Hoosiers or other DOTs or R if on slicks

Thank you guys,

Does this mean I would be running with modern GT3s? Is there a lot of people running in this class?

Thanks,

Stephan

GT3 is a class like GT2-GT4-GT5-GT6 no relationship to the model GT3, as posted in another reply check out PCA GT class calculator that gives you the formula to determine what class you are in. The GT rules were changed a few years ago to include a "factor" that determines class based on really only 3 items, weight, type of engine, and engine displacement.

Nice new car Rich. Hard to keep up with you. In more ways than one.

Dave, look out, one of the first things I moved into new car was radios

I ran GT4S when I had my 3.4 and had to ran 200lbs of ballast to make weight. This is what most everyone does with 3.4's in PCA now. My car's weight is similar to yours. There were 12 cars in that class at the Glen this year. If you don't run any ballast, you will be running against cars with very evolutionized 3.6 and 3.8L motors.

I did what Bull did when I had my 3.4 for PCA. You'll be close to perfect for GTS Challenge GTS4.

Stephan, if u get weight up to 2528 either by adding ballast or eating one hell of a good breakfast, as in PCA it is car plus driver weight to make minimum class weight, you would then be in GT-4

Thank you all for your responses. 12 cars seems like a lot of fun. Do you actually have to dyno the car?

Thanks,

Does the link I posted to the PCA rules not work for you? Seems ok from here.
