Mark Whitner makes some super nice stuff and won the carb shoot out. I get another dommy style carb I am going with him.

1220 CFM dry, just a little less than a 1050 Dominator.

I freshened the engine up this winter and installed new valve springs and had the heads ported this winter (went from 255 CFM to 287 CFM at 600 lift). Car picked up almost a whole tenth in the 1/8. I think the 750 could be limiting the overall performance, but not sure. The car has been best of 6.79 @ 100 with 1.48 60 fts.


My combo is not that much different than yours.

Differences.....
3325#
.040" over 440 with 12:1
Similar flowing iron heads
Ultradyne cam similar in specs to the Mopar .590"
Shift @ 6,500 and trap @ 7,000
6.43 & 105+ 1/8th mile with a 1050 Dominator that was a plug killer puke

Sent my carb to Thumperdart and it is now snappy & happy laugh
I figure a couple tenths quicker than the stock Holley set-up.

Find a used 1050 Dommy in good shape, send it to Thumperdart for re-work or get a new custom carb from him. You will be shocked at the results!
