Hey,

Ive got a 87 camaro with a 350 sb with comp cam, air gap intake and 4 barrell carb, the motor was rebuilt and only has around 7500 miles on it, i went the full 2000 mile break in period but now its makeing this low pitched ticking, almost like a rattle, that does it with the motor rpm, just wondering what this sound might be any hints would be great

when you say low pitched do you me hard to hear or as in low freq?

 

could be simple thing like a loose exhaust bolt, could be as complicated as a blown bearing, perhaps the shop wasnt carefull or didnt wash the block after being machined.

 

Its low frequencie and i think the exhaust bolts are all tight, ill check the collecter bolts this weekend
