The rest of the long block is stock with a Holley Street Avenger intake that is an Edelbrock Performer copy. I don’t know the axle ratio yet, but would guess 3.07. My question is this, has anyone used the 151 cam with an 8.5 to 1 350? The 350 currently has a Melling MTC-1 cam with 204/214 at. I guess part of that thinking is influenced by all the 3 ton behemoths on the road today that people call pickups. Most people just sorta assume pickups back then we're way heavier than cars, but they weren't. If your son's C10 is from the late 60's early 70's era, depending on bed length,etc, it would weigh in the 3200-3400 lb range with a small block, so near the same as Chevelles and Vettes of the same era. This is in a car with 3.70 axle and 2.20 low 4 speed and a curb weight of about 3200 lbs. Couldn't find a 962 at any of the local dealers, and for some reason they were out of stock at the zone parts depot too, so I went back with a 151.įrom about 2800-3000 rpm on up, I couldn't tell any difference between the 2 cams, but at anything under 2500 the 962 definitely pulled better than the 151 does. The face of one lifter looked a little strange, so i figured I'd replace the cam and lifters too.

In the late 70's it had about 90K miles on it and I pulled it down for rings, bearings, timing set and a valve job. I've had an OT 69 Vette since it was about 6 months old that came with the 350/350. GM continued to use it in the 'performance' version of the 350 for another 8-9 years as compression ratios dropped. The 962 was first used in the 350/350 in 69, also an 11 to 1 engine. If you want to use a cam from that era, the 962 would be a better choice over the 151. Do you guys think the cam change will make any difference? I understand the L-79 had 11 to 1 compression, and that is really why I’m asking. The ignition is an Accel HEI distributor. Carburetor will be an Edelbrock 600 and headers with 2-1/4” exhaust.

This is an 8.5 to 1 compression engine with 642 heads. The engine has maybe 15,000 miles on it and the transmission 5000. This truck will also get a 700R4 that I had rebuilt and was in an old Suburban with the above 350. It’s a Small Block automatic, we have a GM crate stock 350 for it that I bought new 15 years ago and had in two other O/T Chevies. It was his Grandpa’s truck and Grandpa didn’t need it any longer, so, now we have a new project. We just picked up a Chevy C-10 for Little Truckdoctor.
