71 302, no bottem end power.
i got a 71 302-W with the 2100 carb and the cobra mustang intake on it. it runs good in high rpms. anything over 3 is fine but in the lower rpms it just seems to have no power. its almost impossable to light up the tires, it's got a c4 in it and the intake gasket has a small leak leaking antifreeze. if i slam the pedel to the floor it dies or almost just about does. timing is advanced a little and seems like the more it's advanced the better it is but i'm almost to the point i can't advance it any more and i know the vac advance works. i'm running out of things to try. i just wounder if a 4bbl would do better and fix all of this.

Re: 71 302, no bottem end power.
Get some gears, 3.73's would be good for a 3 speed.
