L-82 Top End Upgrade
Considering upgrading the top end (heads, cam) on my 78 L-82 for a little more kick. I have been looking at Edelbrock cam and head set that seems reasonable. Cam & lifters P/N 2102, Head P/N 60899 (64cc chamber). I would like some feedback from folks that have done something similar and what performance increase was gained.
Thanks for the info.

The Edelbrock 64 cc heads would be a good choice, but your should consider a more aggressive cam. Check out the Lunati VooDoo cam and lifter sets- 60101 or 60102 in the Summit catalog. A little more duration- especially on the exhaust side and more lift. Good for a street car, stock converter and still plenty of vacuum. Make sure you get new lifters to break in with the cam you select.

Vortec heads are great.You will need a new intake to match the vortec heads.I went with Trickflows complete head kit which includes a cam and roller rockers.I purchased the kit from summit.My car dynoed about 270 hp at the wheels which is abot 350 hp at the crank.Look at my pictures for the dyno sheet.

No just on the motor. Nos came after.I never dyned the car with nos.Also my track time is without the nos and without the 373 rear end.Hope to break high 12s on the motor and low 12s on the happy gas this year!
