That's great Jake... Now you can finally get moving in a positive direction again. Congrats!
Did not get the XWAR from 4WP... looking back would have but was told it already had the 3 year ATK. I had a similar response in the tupy question from ATK. The specific 4WP rep I called was more knowledgeable and I decided to buy the 99 block so that I would have the 630 head instead of another 331. Part# ATK-DA37.might want to add some block brackets to tie into more bungs on the block. stinky fab, more, and brown dog all have a similar setup. Thats the way im gonna go when i do my head eventually.

Id stay away from ATK, when i asked about a new head for my 00 if its the tupy head , they said we dont know cant promise anything. I even asked if they build their strokers with known bad heads and their replay was we use what heads we have. their answers scared me away for sure.
Thanks for the insight. Coolant was burped as we did the break in with a buddy watching it at the front and the heater on. New Coolant temp sensor in september when I overhauled cooling and reads good. Will be working on it next few days and double checking all else.Make sure you have no air bubbles in the coolant system. After that, check your ECT. I've heard of a few having this problem. To be honest, I'd just install a new ECT sensor. It's likely your problem. The ECT likely isn't telling your engine it's warmed up and is staying in a constant open loop thus causing your issue. Or there isn't any coolant getting to the sensor.
On a good note, the PCM for these are very easy to test and replace, and aren't very expensive.
