Reply to "Weber 48IDA on a Cleveland"

I agree with Doug about going to aftermarket aluminum heads. The smaller ports on the aftermarket heads have higher velocity than the 4V cast iron Cleveland heads, which in turn will make more power. If you insist on having the individual throttle bodies, then switching over to a good EFI system is the way to go. The fuel air ratio that you are stating is 11:0 to 1 at 100 mph and not full throttle is way too rich and you are losing power there. A good EFI system with the car being tuned on a dyno is the ultimate way to go! None of these suggestions are going to be cheap, but speed costs money, so how fast do you want to go?
