I had my car set up to run in the NHRA Division 7 "Street Legal Class" while I was running the car in what was originally called the Firestone TNN E.T. Racing Tournament which then became the Sears Craftsman E.T. Racing Series. The fastest you could run in this class when I was racing was 12.99 and my car ran from 12.99 to mid 13's depending on who I was running. ;) It is a VERY mild, but well built engine, along with a very well built transmission that has given me ZERO problems since they were installed back in 1991. :grin: The car has great throttle responce but has a REALLY lousy vacuum out put at idle, which has caused me problems with the power brakes and the A/C system before I removed the A/C for racing. I have installed one of the Master Power Brakes vacuum pumps to try and solve this problem, but have not driven the car with it in place much yet, so I can't tell you for sure it my problem is solved yet.
The main points of my drivetrain include a modified 1969 HP block with matching steel crank, main caps and a set of preped standard length rods, 9.7 to 1 compression ratio, TRW forged pistons, Seal Power rings Mopar Performance .484 - .284 flat tappet camshaft, chrome rockershafts with Mopar Performance stamped steel six pack rocker arms and push rods, 452 cast heads with Mopar Performance standard size intake and exhaust valves, Hemi spec valve springs, Mopar Performance locks and keepers, the original style Torker single plane intake manifold, a custom built 750 Holley 3310 carb and a set of 1969 hp Mopar cast exhaust manifolds dumping the spent gases into a custom built 3" exhaust system that dumps in front of the rear axle assembly and a set of hp mufflers. All of the car's fuel lines have been upgraded from the original 5/16" lines to 3/8" lines and I run a hi-performance Mopar Performance mechanical fuel pump with a Fram HP-1 canister style fuel filter back by the new reproduction fuel tank.
The transmission is a full manually shifted Torqueflite 727 with a reverse shift patten manual valve body and a B&M Quicksilver console mounted shifter with a Hurst Line-Loc unit attached to the "T" shifter handle.
The rear end is the car's original 8.75 housing that has had the original 2.76 non Sure-Grip center chunk replaced with a Sure-Grip unit and a set of 3.91 gears with the original axles. The drivers side left hand thread wheel studs have been converted to right hand thread studs and the original 1966 single line power front drum brakes have been converted to a Master Power Brakes dual line power disc brake set-up with 11" drilled and slotted rotors.
WAY MORE information than you wanted, but hope it helps you out.
