I got a set of BFG Comp T/A's for just under $700 from discount tire - mounted, and with road hazard.

Marv, I think we've all done the bought it cheap and then sunk big $$ into it All part of the fun right?

The most worrisome thing I saw on MA-Z06's car was a red glow coming from inside the exhaust manifold heat shields. As he posted, this was only on the cylinders closest to the firewall. The pipes seemed to be the hottest a few inches from the heads, not right at the head ports. The only other time I'd seen exhaust pipes that hot, it was because the timing was way off. I disconnected the brown/black wire that looked the same as the one I disconnect on my car to set base timing, and I could not find the timing mark anywhere when I checked with the timing light. That was as far as I could go without a distributor wrench (forgot to bring it). What is the proper way to check the timing on an 84?


I'm wondering now if the problem could be a plugged cat. Why else would only the rear-most pipes be so hot? Any thoughts on this would be appreciated.
