Shoulda used a forged steel crank. The motor in our dart is similar but We run the solid 276/280 AS cam and an M-1 intake,950 HP. We have ran 10.0s at 130 plus ,race weight 3130# Steve 7034056-Samoa-maninthestands.jpg (75 downloads) http://youtu.be/fAP_2rxz_GA

I think it could use a better intake, but my guess. 525HP & 500+ lb. tq. 75 Duster, 451 10.87 @ 123.58 NA 97 Z28 6sp., 12.01 @ 115 on a 100 shot 71 Swinger. 360 magnum. 12.58 @ 105 78 cutlass, 469 BBC. 12.70 @ 108 on street tires. http://www.youtube.com/watch?v=Z2kqNmMfheU

I'd run a Victor 340 on that one, similar build to my 414 except I run a vic, 1000hp and a 266/269 Solod roller, I figure mines around 550-ish, but it's hamstrung by the small headers that fit the chassis. Not sure how a Hughes port job compares to my Shady Dell stage 2's but I'd guess 530-ish if your manifold doesn't choke her off too bad up top. Pretty sure Bullet grinds the Hughes HRs, they make good broad power for sure! Last edited by Streetwize; 01/24/12 07:28 PM.
