The cam I put into it is a crane
part# 100082. Lift is 470 both intake and exhaust. duration 282 degree. The motor is a 327.The car starts fine and shuts of with no diesling, But when i get on it it pings and then quiets out in the higher rpms. I really dont know to much about the engine. compression is right around 150 +- 5lbs on all 8 cylinders. I think i feel domed piston,(I could be wrong on that tho).The block is a 67.I was thinking about trying octane boost to see if that would help. I need to give the wife her car back running better than it did or im in hot water. Thanks for any help.

What cam did you have in it before? If it wasn't pinging before and is now and the timing and advance curve remained the same, it sounds like you put a smaller camshaft in that boosts lower rpm cylinder pressure. Your other way out may be to have the advance curve re-done to have less total advance and come in a little slower.

Other possibilities are vacuum leak (lean condition), etc.

start with the basics..recheck everything..timing...etc...and this may sound simple but maybe a higher octaine fuel?

even better...call the cam manufacture customer service or tech line and they are the experts...good luck....oops..dropped my beer.

I think i will try some higher octane gas and octane boost to see if that clears things up. Thanks

i bet your advance curv is off a bit now. with a hotter cam you can not normaly run as much advacne as you did with a milder cam.

i would be looking at the vacuum advance, it is the most likely to give you what i call mid throtle ping.

better yet get a crane adjustable vacuum unit. they come with re-curv spring's for the mechanical advance and great instruction's. i bet this will solve the problem.

oh normaly a minor ping can also be cured by droping the inital timing by around 2* too. but the curve kit is the best way.
