[DeTomaso] Exhaust "Popping"

[Dan Courtney]

The popping DID stop with the new gaskets. Turns out the guy who installed 
my engine used 2bbl gaskets AND they were all blown out from loose bolts (?) 
Also, the fuel pressure regulator was set to 3.5 psi.
Now I just have a backfire after hard decelaration EXACTLY when I touch the 
gas pedal again. Any ideas on that? Too rich? A leak elsewhere in the 
exhaust system?
It looks like I'll at least get The Winged Warrior out to Vegas but no such 
luck for "The Beast". The engine shop gave me an assembled short block 
around 7PM but it was missing some parts. We worked on the WW until 5 AM 
anyway so it would have been overwhelming to try completing the block 
assembly, adjusting the valves and installing the engine. Plus I'm not 
certain they set the cam timing correct. They swapped out a 3 position 
timing chain set for my adjustable belt drive and without installing any 
rockers I don't know how they could have correctly set the cam timing / 
valve to piston clearance.
A few years back I would have run with it and hit the track but I've had too 
many engines blow this past year.
I'll just have to settle for some mellow laps in the WW (hopefully).
