Assuming it doesnt have a crappy converter and totally the wrong gear/tire combo, if that doesn't run at least 10.70's (at a track that's below 1500'-ish elevation), there's something seriously wrong with it.

Fast68,
For now it has the wrong gear 4.56 and 31x13.5 slicks. I just bought the car in June and only ran it once and was disappointed with a 11.80@113.33. So I decided it was time to freshen up the bottom end and new rings, and new heads. I agree it should go quicker than 10.7 but I don't want to be too optimistic. I do plan on changing gears to a 4.88 or 5.13.

'69 Cuda stock 440-6pk bottom end, 9.8:1, 2.14/1.81 906's mild port, 3000lbs all in, CC.650/.650 290@.050 SFT cam, Team G dom w/adapter to 850DP, 727, stock front end w/90/10's, 4800 verter, Hoosier 14x32, 4.88's, l/bars c/overs

10.71@125 NA 1.46 60ft> 9.96@133.9 1.38 60ft with small Hit in 1990
11.23@118 with bone stock 906's.

I think it would've gone quicker with a cam where the intake closed somewhat earlier for a bit more effective stroke/CP....was at 0 sea, knowledge wasn't the best back then, like running 4psi in the slicks!

290@050? 😳

Way to big for you, as you already know.

lol I think my mp590 is too big with 271@050. For only 383 ci.

65 Belevadere all steel we have gone 10.94 on pump gas with 915 heads 2.14 / 1.81 valves....Its a pump gas 440 Source 526 stroker. Its got more in it, we are fighting traction since the car is not tubbed. Its fast, streetable and fun to drive.

With a 526 that has to have some fast port speed

i have a duster 3120 with me in it with a 30 over 440 old indy econo i think heads (non offset rockers) with a old 262@50 solid predator cam 13.7 to 1 dominator and m1 intake ran a best of 9.89 in killer air at cecil md. ports are 270cc 330 cfm flow

My old DartSport had a low deck 451(400 block with 440 crank), MP 590 purpleshaft, ported Eddy heads, 727 with 8" ATI converter, 4.56 gears and 14x32 tires and weighed 3050# with me in it.

Ran 10.0's with a best of 9.96 in good air with a single Dominator.

Ran 9.90's with a best of 9.89 with a M1 TR and two 750 Quickfuel carbs. Extremely fun car, with 11.2 to 1 compression I ran pump gas on the street and mixed in a gallon of 110 octane as an additive. I'm guessing around 650HP.
I don't have any photos on this new computer.

Ummmm... not fast enough.

And it likes a lot of carburetor.....1.50 60ft on that 3400 steel tank plus driver.
