This was with the old ignition system and burned out plugs & wires, and a completely blackened dist rotor that shouldn't have even been working. It should run mid 13's with its recent tune up and the soon to come addition of limited slip |

Still, with 6-year-old 215-65-15 well-used michelin radials on the back of this thing traction is only a dream. Otherwise car looks like a well worn car that sat in a shed since 1983 (which it did) |

I took the car to a local carb/dyno shop for some fine tuning and a couple of "light" pulls. Results: 370 HP, 395 FT/LBS The dyno numbers were at 5150 RPM. The motor only has 4 miles on it, didn't want to twist it up too much. The HP curve was still climbing, about 20 hp per 500 rpm. Torque peaked at 4250 and was 3750 at 5150 rpm. Cant wait to get it on the strip!! |

Here's what my combination posted on 7/22/08 (above) is capable of.
From a standstill at 1/2 throttle. in 98 degree heat. With a dinky, restrictive, 8" air cleaner. http://http://www.youtube.com/watch?v=tGruoBavQmM I'm taking it to San Antonio Raceway tonight to see what it runs, which, given the open dif, 95+ degree temps, and restrictive intake, should be a worst-case scenario. Any bets on what it will run as is? FYI, the rear tires are now 5 year old Michelin Hydroedges - 215/70/15. |
Here is mine. Just finished and started. Some parts are a little dated as the motor was built by me about five years back and stored. Just got back into it and got it going.
