I never once played with the tuning or anything - i just got in and drove it. I'm sure a lot was left on the table. I originally had the XE274H but switched to the nitroushp grind (NX274H). Car slowed down 1 tenth on motor but on spray it did the 11.60 @ 117mph with a 2.0 60ft. If it would have hooked I'm sure it would have been very low 11's.

A good friend of mine has a Vortec headed 400 that runs 11.60's on motor. His car is setup like this: 1981 Malibu weighs 3600lbs with driver. .060 over 400 with stock crank, rods, and kb hyper pistons that give around 10.8:1 (runs on 93 octane just fine). Vortecs are unported and have the stock valves, they have good springs, screw in studs, and all that stuff. Camshaft is Comp's XS282 solid which is 244/252 @ 050, .520/.540 lift, 110LSA. Super Victor vortec intake, 750 Mighty Demon carb, junkyard HEI distributor with good parts and a MSD 6AL box. Trans is a TH350 with an Art Carr "Torco" 9.5" converter (same as my car) that stalls around 4000RPM. Rear has 3.42 gears and a set of 26" ET radials.

...This car is a bad mother ****er for whats put into it and gets driven all over the place. He'll put hundreds of miles on this car on a nice saturday. It's been a best of 11.60 @ 113 on motor and 10.90 @ 123 on a very safe tuned 125 shot. We always joked about putting this motor into my car (much lighter than his, should be low 11's on motor) but it blew up recently and hes moving onto bigger and better things.
