Nice runs with the combo. You ran the same as my best ever 10.04 at 133. My car was around 3,100 lbs when I ran that. Wish I had your motor in my car,mine is somewhere around 600 Flywheel.

Tyler did you use the 1/4NPT vacuum port for brake booster? Seems small but wondering if it worked ok

It would work. The booster doesn't pass much air at all.

I have 2 converted. 1 is my 9.5" nitrous converter for my 6.0 that still flashes on motor to 4600 which should do 5000 with this 427.
other is my prostitute converter that went 6150 on trans brake and flashed 5650 foot brake.
hopefully it works well with the 9.5" instead of 8" for better street cruising

Do you have any dyno graphs comparing them both SAE or STD corrected? 3mph is every bit of 40hp, I dont see with having NO runner length liking that much at all. maybe the longer runner Sniper

What does this car weight, is it pretty heavy? In that DA mine would run 126mph at 440rwhp

dont know what it weighs. I don’t have a back to back dyno either. Too be fair I went 135.9 with the fast mid runner and 139 with the sniper. But the sniper was ran without the vacuum pump because the belt broke. The pump usually seemed to give me roughly a tenth and mph

I probably will but not till winter and with a larger Cam and Holley ECU. This ECU is tapped out. It won’t rev over 8000 and I have my tune scaled 35% so it doesn’t max out dynamic airflow but it still does by 6500

Hits hard limiter at 8000?

Thought weve turned ours a touch over 8 few times over years, definitely have seen it on logs hanging shifts out and stuff

Yeah. I can’t get the ECU to let it go over 8000 unless it’s mechanical over rev.

The fact it wants 8000 + is just bad ***.
my cam is pretty similar.
246/262@.050 .689/.672 112+4 .
