I am taking car to 1/8th mile track tomorrow for first runs. Any guesses what car will run in 1/8th based on following info:

1992 RS Coupe, Interior, heat/A/C removed. New strong LCA's, adjustable panhard bar. Air bags in rear springs. One seat, no cage, dash etc. Stripped as much as possible. Regular doors and hatch. Manual box from S-10.

305 stock block and rotating assembly (later higher comp. pistons)
Chev. Hi-Po heads milled for smaller comb. chamber, minor bowl work, 1.94/1.50 valves w/3 angle valve job.

Edlebrock torker single plan manifold w/750 vac. sec. 1-5/8 hedman full length headers. 235 duration, .488 lift cam w/1.6 roller rockers and high volume pump. Accel dist. 20 static timing advanced mechanically to 37 degrees by 3200 RPM. Accell ignition box and wires.

Th-350 transmission w/cooler and 3,500 stall converter driving 4.10 rear gears. 27.4 inch tall slicks, 10 inches wide.

Rev limiter currently set to 6250 RPM for break in purposes. During initial testing, cranking compression was 220 PSI. Converter stalls at 2400 RPM before brakes slip.

Engine has strong throttle response and idles at 900 RPM when warm. The only accessory driven by engine is alternator. Uses electric water pump.

From calculations, may not get into 3rd gear in eigth mile. Current gearing shows 78.5 MPH @ 6,000 RPM in second gear without accounting for converter slip.

There are two tracks within 1-1/2 hour drive. Leaning toward going to 1/8 because the other track having Ford race next day. Will be busy.

I am wondering if cam is too high range for application? Will torque converter allow engine to get up into powerband quick enough? Car is brackets only, no street equipment other than functioning low beams (I don't see great at night).

Expect to make two shake down passes before my own son starts to drive car in bracket class.

Anyone want to hazard a guess as to fast it will run????? I am hoping it will get into 13's.

Before anyone comments on "Why keep 305?" Car belonged to father in retirement. He is now 84 years old and can't drive. Car had fresh engine at 120,000 miles as it was burning oil. Car had 135,000 before stripping for drags. Father wanted engine to stay, so I changed bearings, rod bolts and added high volume pump along with the above listed items. Kept fuel injection pump and lines, added regulator.

Father (84 year old) actually still has functioning DL. I have told him he can make a pass if he wants. Medical advice prevents driving at night and in traffic.

I am teaching me son and making my own dad happy by using his old car.

 

Race weight is probably around 3,150 to 3,250 w/driver based on camaro shipping weight less accessories, lots of wiring that was useless and general stirpping of car.

 

Car ran 8.80 in 1/8 th at 80 MPH. Spinning slicks through first into 2nd gear.

Loosened rear suspension travel and lubed bushings. Will try again today.

 

Thats a fast NA 305. About 13.6 for the 1/4...

 

Went back today and improved to 8.6795 in 1/8 mile. Engine won't rev beyond 5800 RPM. Not sure if valetrain (springs), fuel or ingintion is problem.
