But its also a bigger engine though what's the 6.25 compared to a 4 cylinder

 

True, but generally more flow is NEVER a problem. Our factory pump was 8 GPM.

 

I can guarentee that you still have trapped air.....

w/o Opt. B it is very hard to get the system to purge all the air. I just installed the GMR dual pass, and a new pump while I was at it. My Opt. B tank bled all of the trapped air almost immediately. Un-bolt the fill bracket from the blower (if you still have one), and lift it up a bit. This will help burp some of the air pockets out of the coolant.

 

Ill have to give it a try(I'm no mechanic in anyway) when I get done work.

 

It's ok man.... we all start somewhere.

By the way.... where in PA are u located??

 

Right on the outskirts of quakertown and pottstown

 

Oh...ok...jw.

I've seen a car around my area that looks very similar to yours. Thought I would see if it was you. I'm a little north of scranton.

 

Yea there's like 5 ss's around here atleast that I know of so getting help for this car is kinda hard

 

I have zzp stage 3 he, dual pass, option B, 2.8 pulley, zzp IC pump and at cruise I run about 20-30 degrees over the ambient air temp year round. When I installed it all it still took a bit of driving to purge all the air but the option b does a nice job.

 

Thats whats css.net is here for

 

If your IAT2s are 20-30 degrees over your IAT1s.. you're not in too terrible of shape.

 

Yea it took a few days but now I running like 84-95 will driving so its all good I guess I just had some air bubbles in it but thanks for all the help guys

 

This.....

It's very hard to determine what IAT2's actually are, because they can vary soo much. Things like throttle position, daily temp, modifications, etc. can alter them. I always say my IAT2's are around 15*F above IAT1 on average. On average meaning sometimes they dip below 15*, and some times they are over 15*. The best way to test them is to take a nice steady cruise on the highway.
