Missed on this combo?

Of course, the test I’d like to see is the old version dyno tested back to back against the new version.
:steering:

On something hot enough to really show the difference.

Oh hell....... let’s throw on a set of TF190’s while we’re dreaming.

the new head, that Vic Bloomer redid from scratch, has been on and off the dyno at BES. It was on a 420 ish cube motor with a 263@ 50 roller. I dont think its my business to say what power they came up with, but it was very impressive, and Bischoffs has a very good reputation.
The new heads were also installed on a drag week car, right before dragweek. Rollercam, true pump gas, 3175 pounds.
Averaged 10.20’s for drag week, went as fast as 132 mph, with less than ideal 60 foot times, and missmatched
convertor, couple other teething issues.
And this was far from mineshaft air. Trying to think of any other 132 mph Abodies on pump gas with no prior testing, regards non offset heads. Thought that was very impressive.
Last i knew, 2 sold sets were delivered to Monster Mopar at Norwalk back in late July, and 6 or so other sets were in the process of being available for purchase.
