So i bought an 88 camaro from a guy here in alabama, he told me that the 305 blew a head gasket so instead of fixing it he put a 350 4 bolt main in the car. the motor had a slight miss (number 4 spark plug wire not connected), so when purchasing the car i knew i would need to do a tuneup. I thought... not a big deal, i only gave 600 dollars for the car, other than that it runs great. Well about a week later i noticed that oil was leaking around the timing chain cover, so i took it off to replace the gasket, and boy am i glad i did, the guy put a chrome timing cover on the car(i didnt realize it until i started to take it off) and all the bolts for the cover were finger tight. I figured, ok im gonna replace the gaskets anyways. so i take it off, and the timing chain is stretched to h*** and the bolts for the cam gear are also just finger tight. So now im gonna buy a timing set. i was wondering though, what is the real difference (performance or otherwise) between a single and double roller timing set, and which is better. i would just assume buy the better now while i already have everything apart. Also if i were to get a double roller, will a regular timing chain cover fit over that? i have alot of plans for this motor, it was just rebuilt, (i know because i have reciepts from the shop and i went and talked to them) and im wanting to put a bigger cam in it while i have it all apart. so any help would be awesome.

sorry for the long post, ad to explain it all.

Double roller is just a different chain design basically, it's stronger, but won't provide any more power. Not that much - get the double roller - it all fits and everything ekle remains the same.

 

Thanks I appreciate the reply if it will all fit under the timing cover I have then that's awesome. I'll go pick one up in the mornin. Thanks again.
