I talked to the fella that rebuilt the 340 in my 69 GTS in Nov. of 2003. He only kept receipts for around ten years on the engines he has built. I have the original receipts from 2003 and thought it was cool to talk to this fella that is in his mid 70s. He remembered a lot about my car but could not tell me what cam was in it. On the receipt it says Comp Cams camshaft and lifter kit. It was a bit over 200.00 back then. It is a hydraulic and has a bit of a lopey idle to it. It looks like the valve springs were 90.00 and the rocker arms were around 120.00. Any good guesses? Thanks! Ted
