Classic over carburetion problem?

Just to add some actual race facts to this. ....Back in 1982 I was running a no's match '71 340 street/strip Cuda, stock everything, 3.55's, plus the motor had an ally intake of which I can't remember now but I swapped it out for a Holley Strip Dominator, it had a 750DP and small 1.5/8" hdrs and a .484 hyd. purple cam and 3500 stall verter. It ran real good but I wanted more as we all do so I got hold of an 850DP of which all my race buddies said was too big for such a small motor, well it picked up almost 2 10ths in the 1/4.:thumbsup:
I like that..Wait for July after I'm broken in
