Dave, Gary, Leadman and the Texas Dave....
My last trip out (end of Sept thru 1st week of October) it was extremely hot in the Palm Springs area and I didn't help much by traveling in the heat of the day.....
Climbing out of the Coachella valley (west bound I-10) I watched the temp gauges climb and felt the engine drop power, I feel it was vapor locking and starving the engine with cooling gas which is a first on this rig.
I've purchased new plugs & wires and will check the plugs for abnormal fouling but one thing I can say is around town it ran fairly well again....
Driving back home in slightly cooler weather it ran fine except when I stopped and let the dog out for a quick run, As the engine was left running it stumbled getting back on the super slab and up to speed....It smoothed out and ran the next 40 miles without problems....
Just wondering aloud if they started the new E-15 program, Gawd I hope not but Kalifornia will sneak anything into what they think it right...

Here's a neat guide to expected PSI's in testing a '88 or so P-30-based GM 454 gasser fuel system like mine:

ALSO of interest, is an earlier question of mine in another thread related to the unusual (to me!) "formed" steel manifold on my 454 engine:

Explanation for that design stated there were 3 different materials used in exhaust manifolds - cast iron, nodular iron, and:

STAINLESS STEEL - Stainless steel had come into
use with some past production 454 CID engines
with the new emissions Systems. Starting in 1985
midyear through 1989 federal and 1989 California. It
is very difficult to produce and the materials cost is
high. The net result is that the total cost of using

stainless steel manifold vs. the manifold cast family itself is extremely high.

SO, apparently mine is of the stainless steel variety - remaining question relates as to any efficiency differences between the stainless - which LOOKS to be better flowing - and the cast iron versions...

ANYWAY - GREAT pointer and info - thanks again!

Jim, We went to Wyoming the middle of September and I suspected there were different fuels being sold. A couple times I swore I smelled MTBE and there was a definite increase in pressure in the fuel tank. I had to loosen the cap slightly and wait quite a while before removing it.
Also mileage varied considerably with driving conditions not varing much.
I did not have any driveablility problems other than a slight reduction of power at times. I haven't modified the jetting or adjusted the timing so my engine runs on the rich side which may have allowed the engine to run close to normal with a leaner fuel.
