Thank you for the responses.
A couple of time slips:
1.308 3.674 92.752 5.646 123.218
1.311 3.683 92.390 5.667 122.548 same day within and 1 1/2 hours

Fastest 60ft was 1.275 but got out of shape. All times on a pro tree with the engine going up on the 5600 chip 6500 stall slow.

The 461 SBC does have a tunnel ram and two 1050 Dominators,

Just bought a Power glide with Reid case pro tree transbrake 1.80 cut 1st gear. It replaced the power glide I took out when the input shaft broke. Now I have a spare power glide.

Something we found that might help is the front idle mixture screws were 2 1/2 turns out and the rear idle mixture screws were only one out. We changed them to 1 1/2 out and it wouldn't idle. We turned them out to 2 and it idled fine. I didn't know if it came from Pro Systems that way on purpose. Patrick has helped me tremendously working on the tune. Always responds to my emails.

Ok, so it runs good, makes good power 123mph. Now you have the part that potentially seperates you from others to sort out, the start.

Thanks for the responses.

stall is 6600 and it is 3100 with me in the car and fueled.
This is a 461 SBC with dual 1050 dominators.

The tq does follow the hp and it's up kinda high in the rpm range
