Parts for rebuild - Somewhat urgent
Two questions:
First come the sparkplugs. If I am correct, the stock Autolite plugs for the L36 are #606. What are the corresponding Autolite numbers for one, two, and three heat ranges colder? We need an answer to this question tonight, so all help is appreciated.
Secondly, I've read through the thread about changing to an adjustable vacuum modulator for the 4T60E in order to firm up the shifts. I would like to know where that modulator is located in the engine bay, and also some part numbers for buying one from Autozone or O'Reillys.
Thanks in advance, and there may be more requests posted here throughout the night as we continue putting the motor back together!

Thanks Mike!
So you install it as per the "1986 and newer" TH-440?
Also, if anyone can give me info about spark plugs, it would be greatly appreciated. We NEED colder plugs before we can fire this baby up, so I'm going to have to find out one way or another before the night is over.
Thank you!

I'm not sure how the 606s rate compared to 605s, but here'* a list that gets cooler towards the bottom;
Autolite 605
Autolite 104
Autolite 103

I'm curious as to why you want to change the heat range on the plugs. Are you drag racing?
If you're not, I'd keep the factory heat range.

One reason is the higher compression. It'* over 10.1:1.
Since a supercharger essentially bumps compression, I'd go with the SSEi plug, if it'* different from the "K" engine plug, and stop there.
