Juice-
I have a 69 Camaro too & it has a Dana 60 w/ 488's... 9.5/rim 29" slicks I drive on the street WAY more than on the strip. Anyways, You are right... I think a 390/411 would be just about right for your purpose. My car turns RPMs w/ those gears & gets my stall hot. I will be doing the same thing myself... once I get the courage to to a R&P (never done one yet). Anyways, to this day I am impressed how the 1st gen Camnaro's seem to launch straight!! (this is my first Camaro) Mine is stock suspension too with frame extentions. That sounds like a fun street car to drive to the track. Anyways, do you have the RS grill/Hideaways? I want to do RS covers w/o the hassle of the whole kit... I have the grill, but I need to do the rest. You might let me know if you are ever selling any 69 parts too. Scooter
