Default Difference in temperature between intakes

Torker2 vs Air-Gap

torker 1st number air-gap second
drivers pass
headers 642/560 644/555
intake 166/172 171/176
radiator 182/186
top carb 115/120
exhaust tip 77/80 76/82
top air cleaner 142/144
fuel reg 158/170

Pipes ( chambered ) about a foot after headers 175 didn't do it on torker

Both numbers were with car running after 20 mile ride
1976 350 11 to 1 pistons on 91 oct

Don't remember outside temp but think both were around 80
Also don't understand 100 deg difference on headers
Much better performance with air-gap but think it has a lot to do with the guy i found to tune it .After playing with it for many years it finally smokes the tires from idle .

intakes dont make much of a difference unless the current one is really a bad match.

If you made the temp measurements with the Torker intake BEFORE tuning the engine, that's why the exhaust temps were much different. Your tuner likely changed the timing at idle. Stock timing setting would be retarded (and running hotter) than where your tuner placed it. To me, it looks like the guy who tuned your engine knew what he was doing.

I think he was referring to 100degree difference in exhaust temps left to right....

Carb issue?

the first set of numbers with the / between them is the drivers side the second set is the passenger side . the 80 degs difference is from 1 intake to the other at about 2 inches from the heads on the headers.

The person that did the work said when he started working on it , he first pulled a plug and the torker was running rich .
