Title: Can FE Heads accept Pyrometers for EGT sensing?.... On Barrett Jacksons stage
Post by: Qikbbstang on May 08, 2011, 10:01:49 PM

the resident expert Hot Rod/Muscle Car Guru - Steve Magnante also of Hot Rod Magazine/Hot Rod TV remarked upon his inspecting a Cobra Jet MACH 1s engine bay that: "this is a serious engine here", because he went on to say: " I can see where the exhaust section of heads had plugs in them where they had the pyrometers from when they dyno tuned the motor".   One of those Unique FE things we all know but they don't.

Steve obviously did not realize that FORD drilled em as part of the Thermactor smog package. Regardless I know it's closer to the valve pocket then common primary header tube mounted probes but could the tops of the FEs exhaust passages be equiped with pyrometers w/o causing problems?

I'll bet they could BB; I've never thought of that, but you can get very thin thermocouples that would probably to into the ports through the thermactor holes.  It would be interesting to see what temperatures got recorded there, relative to the temps normally recording a few inches down the header pipes...

Forgetting what you could use them for...........


How could he not know about the thermactor tubes?
I love FE's but even I hated changing plugs on a Stock CJ Mustang! I even got PAID $50 to do it!
