test your car with the borrowed and hopefully known carb.You can power time your car for testing,by plugging vacuum advance,set max timing around 34- 36 total timing.This usually happens by 3k rpm.make sure the weights are free in the distributor of course. I built a low compression 400 for a friend before,it ran 14.1s and got over 20 to the gallon. with 2.7 gears and stock stall,stock 400 heads,,,78 monte carlo
