First time cam degree
I'm running a craigslist 360 which had very little history other than stock bottom end, "small cam," and 2.02 stainless valves. The engine ran pretty strong, but would nose over HARD after 5200 rpm. I took it to 6k one time, but even in first gear it barely made it.
It sounded healthy at idle, but needed 1100 and 22" initial to pull 11 inches of vacuum, and if I set the idle lower it would stall in gear. Performed a compression check and although the numbers were a little spread, everything was within 10%.
Decided to swap in a new cam, and was surprised at what I pulled out; xe262h.
So I'm installing a summit 480/480 cam(cam card attached) using the existing double roller set. I've checked the cam timing about 8 times so far, checking tdc with a piston stop each time, and am coming up with 110-111 each time.
First question- Am I right to assume that this timing set may be retarded, and contributed to the xe262's idle and rpm issues?
Second question-I've ordered the summit billet timing set. Should I install the cam
At 107 per the manufacturer or advance it? I don't plan to take the motor past 6k.
The engine will be turbocharged.
