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. 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. 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.
