Hi All;
On my 1963, I finally managed to straighten out all the bugs with the drive train. Last steps were to replace the rear with a correct ratio and then to get the drive shaft balanced which it really needed. Now the car runs like a watch; tons of power and smooth as a baby's you-know-what...
Yesterday and again this morning I ran into a new issue and that is power loss during hard acceleration. This is a 340HP car with the Carter AFB. When I really lean on it, it really picks right up and pulls strong (sounds pretty good as well). After a few seconds at close to wide open, it will stumble... this is not a miss or a break up but rather a loss of power. Once I get off it and resume at less than full throttle, it is just fine. Normal cruising is fine as well as is normal gradual acceleration and highway performance.
I'm thinking fuel system problem, perhaps a pump which cannot keep up with demand at WOT. The pump in there now is from Corvette Paragon, one of their #4657 reproductions.
Any thoughts??
Thanks!
Joel
