Can someone recommend such a tool - preferably not crazy expensive? What heat range do I need to look for?

The infrared gun will measure temp if the head pipe itself... not as accurate as directly measuring the gas temp and also responds slowly to changes. Accurate enough to be meaningful? Don't know.

Thx for the heat range advice They come in all sizes and shapes here in the U.S., I have a very small one that fits into my fingers with a button, not like a handheld gun at all Harbor Frieght probally has several cheap ones Buy a good one Mr.Cab Racing and winning with Mopars since 1964.

Thx for the help! 67 RO23 clone with 6.1 SRT Hemi and dual quads. Soon to have Drag Pak induction and Throttle body.
