Thanx for the replies guys.
TAKid,the pad you mention is where I found XXX no cubes cast in.
John,You are correct on the block #481988,looked like an S.Dug into the grunge by dist and found K087 and on the front for the eng code I found X7 which says auto which it is.I have not pulled a vlv cvr yet,but a # just below the vlv cvr is 8138.I assumed they were 8s because they both have a GM8 cast on the outer exh port(dvr rear frnt pass)How do you tell 4s from 8s?
Thanx again guys
