I have the chev idling and within about a minute the extractors are glowing red. Why would this be happening? or is it normal, it doesnt look normal.

maybe your timing is to advanced?????????????????????????

i think you mean to retarded, making the bang too late and pushing unburnt or burning gas out into the extractors. check it, advance it til it pings and back it off 5 or so.

or the better thing to do would be to use a timing light

Why? some motors are happy with more static/advance than others, the only way to find out how far you can go is to find detonation point....

Balancer could be slipped etc..

check your timing and make sure your not runnig lean on fuel air mix.

leave it and cut out your inner gaurds. drive it down the street on a thursday or friday night (whenever the knobs are out) and let it sit there idling away glowing red.

it looks horn.

other than that for fear of being unpopular.....timing.

timing had it..thanks all.

alot of chevs ive seen have done this, but not that quick, usually after u have driven the hell out of it for 20mins

x2 maybe just tape em up with some heat tape, should be good fore a few extra hp as well

Why not just tune it correctly

I've heard this before - what's the theory behind the claim?

i think it helps with gas flow movement as the pipes are colder. also keeps heat away from the heads which means cooler burn and ability to run more timing advance if needed

IM prob wrong , maybe ask google
