i discovered the other day that the number 3 header tube glows the bootom half of number 4 gets red and number 8 gets a tad hot. i also noticed that my car has been running upward near 250*. i bought a new t stat so hopefully thats my overheating problem. info on my car it has an eddy 600fm carb weind intake and the rest is all stock. hasa complete msd ignition and i belive the timing was set at 17*. so can anyone point in a direction to check. o yea im gonna run a compression check on number 3 and 8 tomorrow.

are you sure your timing is advanced properly/ set right....retarded timing ..excessively can cause that.....if you set it correctly or what you think is correct and you still have a stock balancer/original one it may have spun on the rubber to where when you set timing to where you think it is correct you may actually be way off

sounds kinda like timing maybe? or running to rich not buring off all the fuel??

if you have a carb and the rest is stock, a 190lph pump (stock) is the wrong fuel pump

i was thinkin it may be too rich but im gonna run a compression check and make sure i have atleast good compression then prob go and have the carb adjusted for the stock parts. it was originally setup for gt40p heads and ecam

How's it idling? A little fast? Check for a vacuum leak.

I had a car that backfired through the carb and blew off a vacuum plug.
It was sucking air/vacuum leak. The idle was a little higher, that was the only symptom.
Didn't know that this happened til I got home and checked it out.
I drove it home about 5 miles and popped the hood and the header tubes were glowing, I found a rubbervacuum plug missing.

so are you running 40psi (stock)of fuel in a carb that needs 6-7psi of fuel.

the richer you run the cooler the engine runs... lean = hot
pull the plug and see what it looks like?

sounds lean to me - isnt 17 deg @ idle a bit much?

Yea, sounds like way too much. I'd take it back down to 10-12 degress and work from there.....I'd go about 14-15* tops....
