cam talk

The slips show a huge improvement in the response and reaction of the package. So what changed and what didnt? You lowered the effective gear with the tire swap and lowered the torque peak with the cam swap. I dont think an improvement of .17 in 60' with little improvement in the incrementals says it's the cam choice. So what do I think the package needs? You still have not said what the trap rpm was and is. IMO, the trap rpm will tell me what carb might be best. Under 6500, the 750 will prob be best. Over 6500 a 4150 series 850 would probably do better properly tuned. The convertor IMO is all off. Which is another reason I think the car is sluggish and lazy. And knowinf the trap rpm vs mph you can calculate slippage. Not as good as trap rpm in the 1/4, but doable. I think an 8" with a slightly lower stall speed might be better. Another trick you can try would be to tighten the lash on the exh side by .005" and see if the car picks up.
