I was wondering if someone could plug this info into their DTDyno and give me a number. Also looking for opinions on what to do next besdies the obvious power adders. Here are the engine stats: 350 bored 40 over, so a 357 cubic inches, Speed Pro coated hypertectic pistons dome volume equals -11 cc's, and World Products Sportsman II cylinder heads which yield a 9.86:1 compression ratio. Also, eagle H beams 5.7 inches in length. Comp Cams Pro magnum roller rockers 1.52:1 ratio. Cam is a Crane cams Emissions Legal Powermax camshaft part Number 114122 hydraulic flat tappet with gross lift at intake valve 423 and at exhaust valve 446. Intake duration is 264 degrees and exhuast duration is 274. At .50 lift the intake is 110 degrees after top dead center and 204 degrees duration. For the exhaust 110 degrees before top dead center and 214 degrees duration. Exhuast is 1 5/8 Edelbrock TES headers with a custom single 3 inch exhaust pipe no cat Flowmaster 80 series muffler, but I also have an electric exhuast cutout. The MAF has had the screens removed, and the intake is stock with mild porting to the restrictions in the plenum. Dual snorkel air intake with Kool Blue filters and restrictions removed. TPIS airfoil is also there, with the AIR pump and smog pump removed. TH-700R4 with shift kit and corvette servo and kevlar race packs. Teh rear end is a Borg Warner 9 bolt with 3.36 gears. I have Mickey Thompson ET Street Slicks. The computer is from a 305 TPI and I have an adjustable FPR, and a Walbro 255 fuel pump. Stock injectors and stock computer. Roll bar 8 point and fiberglass hood, t-tops, and stereo upgrades but rear seat deleat. Lightweight racign seats and 5 points harnesses. I weigh 130 pounds, I think that is all the info anyoen should need for Quarter mile times and Dyno info. Any question just post please.

Thanks a lot guys.

350 4.000
trick flow twisted wedge g2 heads 2.02/1.60
750cfm carburetor
single plane intake
small tube headers with mufflers
crane energizer .454 camshaft

assuming the valves are 2.02/1.60

peak 298HP @ 4500RPM & 400LB TQ @ 2000-3500RPM (flat line)

pretty much the same with 1.94/1.60 valves

is that at the crank or wheels? Also, any indications of et?

thanks brett

at the crank

desktop dyno 2000 doesnt have any place to input transmission, gears, etc so not ET

sorry
