They are fine carbs, just not for racing
Don't tell that to the guys that race NSS with MAXWEDGE cars <img src="/ubbthreads/images/graemlins/laugh2.gif" alt="" />
again they use TWO! and if they were allowed to run TWO DP's they'd be 4 tenths faster.

Plenty of the N/SS cars run 2 850 Holleys.
There are 4 of us in N/SS with similar combos as far as weight, cylinder head, cam , etc. They run 9.50 or 9.75 index with the Holleys. I'm the only one that still runs Eddy 750's. I run the 9.25 index. Car has been 1.29,9.12@147.7. Carbs are box stock with the chokes removed and rejeted. Squirters are stock.
