My buddy has a mustang dyno. I am going to try and get a few pulls soon if he isn’t too busy. I had my 408 demon on it and the numbers seemed right- 350hp 400tq at the wheels. I never got that car to hook at the track but it mph’d 108-109 consistant so it doesn’t seem like an optimistic dyno.

Whatever numbers I get are just for fun- I am curious what it will say but my ego isn’t hinged on it or anything! I’m sure we’ll fiddle with the timing and WOT AFR for max power but it’s not like I’ll ever dead hook it on street tires.

Anyway- here’s the fun part: what will it make to the wheels?

Source 400/512,
unported stealths,
rpm intake,
sniper efi & hyperspark timing,
Small tube shorty headers, 3” downpipes, 3.5” flowmasters
10.25:1 CR,
.507/.510 240°/246° Comp hydraulic flat tappet
727,
3.21 gear 9.25 sure grip


I was building with a goal of 475-500hp & 500+ tq all done by 5500 so my guess is 380hp/425tq at the wheels.

Closest guess gets a free mopar tattoo at my shop if you’re into that sort of thing, or a shot and a beer if yer not 😉 I’m near philly.

Video of idle and rev with the holley 950 used for break in and not enough timing at idle. It’s even stronger and smoother now 👍
