gpx 433 clutching

[rlm2268]

Does anyone have a good baseline comet clutch set up for a stock 75 gpx 433, all stock except for 38 flatslide carbs. Or if there is a good set up for the stock primary which i have. Will be used for vintage rides and drag racing my buddys. Thank's

i like the C-2 in the comet with silver/black or purple spring
this gets me around 4K engagement and 8K shift out. purple slightly higher

Would that be the same for the P-85?

FOR STARTERS, RUN A 78-79 SRX SECONDARY, WAY BETTER ON GPX. THAN FOR A COMET ON A 433 GPX, START WITH A SILVER OR SILVER/BLACK SPRING IN PRIMARY WITH F-2 WEIGHTS. 3:16 (yammie tony)
