Predictions?

Not that mild on the cam IMO, A hate to say it, but something isn't right, that car should be in the low 12s at around 108 with that combo, seeing your in Iowa, i'm sure the Alt. isn't that high, I ran 12.5s at 105 all day long with WAY less then what you have, that was on a 1.79 BEST 60ft., best 1/8 ET was 8.0s, you need to start tuning or find out whats up, here was my lame combo.

71 dart, all steel including hood/bumbers, MBs & steering. Guesstament race weight was 32-3300 lbs.

95 junkyard 360 short block with quit a few miles.
RHS heads with stock ports, 1110 springs
Reground stock roller cam from Bullet cams. (470/470, 218/218 @50 on a 112)
Stock rockers/pushrods
Crosswind RPM airgap, 650dp
Summit headers
MSD dist with Mallory box.
Stock 904 with cheetah RPVB
PTC 11" 2800 stall
3.73 gears, 28" DRs

On the sauce (125) it ran 7.4s @ 95 1/8

This was allways shifting at 5100 because thats all she rote.

I'd weigh the car, just for comparison, I had a 75 duster with an all iron 451 lowdeck, all steel including hood, took of both complete bumpers weighing 165 lbs. Aluminum rad. MS & brakes, with race seats & it had the fold down rear seat, The car weighed just under 3K lbs, around 2930 without me over the scales at Ennis raceway, I was shocked to say the leasst, So i'm sure your 74 is not that heavy, I'd guess around 3200 & change.

Just listened to the video, that cam sounds good & quit heathy, not too small at all, excellent responce, I'll change my low 12 responce & say that car should be around 12.0s @ 110, If i had my engine sounding that good it would be in the 11s EASY, something is not cosher.
