i made sure that the cam wasnt a tooth off or something like that making the valves advanced or retarded

also i have a msd 6al on it too that could possibly be doing it too but i dont know

 

wtf is up with the frankenyota!?

is that a "custom" extended cab?

looks stock! good deal!!!

you still haven't answered the question on whether the carb is a 92 or an 81?

 

about a hundred hours of work but man it was worth it i get head turns every where. anyways from what i can gather it is off of a post 85. frankenyota is exactly the thing because it is made up of all different parts. the thing is the original engine i had in it was dead and a buddy of mine had a 92 efi 2 wd and i swapped everything (damn ill never do that again) so when that died i had to smog and reg it anyway thats when i started the proj. so it has the 92 efi engine in it the engine is set to 92 stock specs and i have it set up as the 81 carb. i had bought a donor 81 truck for the smog parts but the carb was in ˟˟˟˟ty condition so i had to use whatever i had left. so i set the carb to the 81 specs with all the vac diagrams

 

It sounds like your exhaust valves are opening too soon with the mixture still burning. Check your cam timing. Retarded spark timing will cause the mixture to continue to burn into the exhast also. Again, check your cam to crank and cam to distributor timing.

 

The timing is advanced to much, or its leaning out bad. One or the other.
Only thing I have ever seen make a manifold glow. Usually if a cat is clogged...the cat will glow not the manifold.

 

i have a completely new exhaust and a magnaflow muffler so no blockage at all and the under hood temps are not really that hot plus i have no inner fenders being that i have a tubed out front clip.

 

like i have already said i have already checked the cam timing and it is right so is the dist.

 

you checked the timing with a timing light? how did you do it? explain your technique.....

 

The OP will be on a vacation for a little while - we will soon bring you back to your regularly scheduled programming.

Why, what'd he do?

 

Nunya!

Oh, and he elected for his vacation to be an early retirement - thread closed.
