I'm having trouble getting the mixture rich enough on my new 514. I have run jets as large as .0149" on the 8896 Dominator and am still too lean. The combination includes a Victor Jr. intake, Blue Thunder heads, cam is 258 intake duration / 635 lift, 268 exhaust duration / 645 lift at .050 off with a 112 degree intake center line, Mallory Unilite / MSD 6M and a compression ratio of 9.5 to 1. The short block is an internally balanced SVO 514.
I am picking up horsepower with every carburetor jet change, but something doesn't seem right.
