Thread: Tunnel Ram Problems

Tweet

Hey guys, I am new here.
I have a chevy 350 with an Edelbrock tunnel ram with 2 Edelbrock 500 CFM carbs.
Idles great for about 4 minutes at about 1100 rpm then ramps up to about 2200rpm and the temp shoots up, I have not let it go past 190 degrees............
Any thoughts were to start?

Idle speed increase with heating points to a vacuum leak, but why it runs good for a few minutes beats me. Something heating up and opening up a leak, I suppose.

will check that out, how about the motor back peddling when shutting off?

If its idling fast and you shut it off, enough gas/air is getting in to fire without spark. It will run either way under those conditions.

Thanks very much, I am checking that out today.
