the old reason i am asking about a 6-bolt is because there are 3 junk yards in my area all three of them have a few good -6-bolts but not a single 7-bolt. that is y i ask. and as far as the rebuild what would u recomend one with just gaskets like you said or the whole deal w/internals? money dosnt matter unless we r talking like a grand more or some thing

 

ok guys all the timing is in check, could it b a sensor going bad. idk cuz noting fixes it. its idleing at like 1000 then after a few revs it gose haywire and hits 200 then dies

 

anybody? is there any other thing that would cause this?
