Some people were asking me my gains from the TR230 and 243 heads
60hp and 15ft/lbs at the rears from a cam upgrade. I switched from the stock 241 head to a brand new set of Z06 243 heads when I did the cam.
The car had a different mail order tune for both before cam and after cam. I believ both dyno charts to be "corrected"
