my exhaust is HOT!, did i go too far??? Options

[nebreitling]

this is the new 2056 w/ 44 idfs, 9.6:1 comp, euro race header

problem: exhaust pipes and cylinder heads *seem* too hot, particularly on the passenger's side. oil is not too hot. i don't have a pyrometer.

i'm using my old '75 2.0 distributor w/ the vacuum advance disabled -- it has like 8 or 10 degrees of mech advance. can't afford a mallory right now. timed to 27 degrees, but the engine seems to want a little less advance when idling around 1800 (still setting up the carbs)

(any one have a 205aa or an 050 to sell?)

still working the carbs out, but they're not *bad*. if anything, a bit rich.

have all engine tin EXCEPT the driver's side cooling flap. the passenger's side flap is expoxied DOWN, such that air is forced through the oil cooler. I've seen numerous carbed cars with this set up.

i took the muffler off and the exhaust blows SIGNIFICANTLY stronger through just the 4-1 collecter. this seemed to cool the pipes off a bit, but it still seems a little hot. compressed air flows through the muffler okay, so i reattached it (don't believe it is plugged up).

i know i'm pissing in the dark here, but any suggestions that you guys could offer would be apreciatted.

Even 1400 is lean!

the EGT curve is bell shaped the EGTs will rise as you to a point, then decrease..ie less fuel for the fire.

I like to trot this out every once in awhile
