i have a79 with the 351m ive had nothing but bad luck with,if i can get this 87 half rite im going to try to get that thing going,last time i had it running i could rev it up and throw a three foot flame outa both exhaust pipes,things a mess.

ok thanks, im going to take it out and tear it down and take a look.ive tried the merical in a can stuff but never have had much luck with that kind of stuff

the stock gauge fluchuates,but after truck runs a while goes all the way to the bad side and engine begins ticking.

should i replace the cam bearings too?

could anyone tell me what all could cause oil presure to drop after engine warms up,im going to pull it out and hate to miss anything.87 f150 w/302 about 138000 miles
