Floyd, I'd bet your short times ,probably up to the 660' would pick up considerably. ......I've seen guys use way to big a carb and have success,but I've also seen many who struggled with the problem Bob is having. .....Bottom line is you have to try different carbs to see which is best for your combo..........A while back,.I tried a 1050 on our S/ST AMC Spirit which has a very healthy 401 in it. 13 TO 1, big roller ,ect .....It picked up about 1 mph ,but lost over 2 tenths in ET! , compared to a good 850 carb. ......Tom
