I purchased a pickup from a "friend" that has a problem.
About a year ago I helped put a much too large cam in a basically stock 350 in this pickup.
Here are the specs:
1977 GMC shortbed, about 3800 lbs. 3.42 ratio 10 bolt and T350 with TCI converter, probably about 2400-2500 stall with this engine
350 bored 30 over with what appear to be stock pistons
Junk heads with 76cc chambers, "Z28" valve springs, new standard valve job
Performer RPM intake with Edelbrock 600
Headers through 2 1/2" exhaust
Comp cams 230/230 @.050 .480/.480 lift
Pretty sure this is way too much cam, truck is pretty much a dog.
I have a set of aluminum Corvette heads with (I Think) a 58cc chamber. Would these help cure the junk-heads-can't-breathe-and-low-compression-with-too-big-cam blues?
Thanks!
