For those of you who have converted your L98 C4 to the Edelbrock Pro Flow XT intake, can you let me know which specific water neck / TSTAT Housing, and which MAP sensor you used in your install?
Right now the outlet of the thermostat housing won't clear the alternator and the serpentine belt, and it appears that Edelbrock is only supporting MAP sensors with the o-ring that fits into the manifold rather than being fastened with a bolt like the older style MAP. Curious what you had to do to make these two work for your install.

Greatly appreciate the help.

Thank you. I tried the GMPP housing that was referenced by the Super Chevy article and that one must be slightly different than the TD. Going to try that one next.
Any issues with the MAP staying in place just using the rubber fitting?

Here is a pic of my trans dapt......not a lot of room but it fits with my BBK throttle body.If you are using a stock GM throttle body then you should have more clearance.

Thanks for this pic. We're using the Edelbrock LS1 TB so the clearance I believe is about 1.5 inches. Most of the necks that we've found point the wrong way.
I'm using a 45 degree bend that is 1 1/2 inch at the Trans dapt 9229 T stat housing then tapering to 1 1/4 inch. I'm using that to get around the A.I.R. pump.
I believe I found it on Amazon.If not then Ebay. I would have to go through the receipt folder to be sure.
