Default TNT Nitrous plate

I bought the TNT Nitrous plate a while back well after breaking in the new engine I want to install it. The problem I'm having is when i put the plate on and go to put the throttle body on the tb hits the thermostat housing. anyone else have this problem and did you grind the thermostat down the iac or both?

prolly will have to grind both. IIRC most of those Nitrous plates are designed for TPI cars, so you'll have fitment issues on our LT1s. Nitro Dave's plate is supposed to have pretty good clearance IIRC. anyways do some grinding.

I grinded the top of the thermostat housing a bit and was cautious of not doing it too much for obvious reasons. It just took a little finessing but went just fine. It was my only holdup with this kit.

I had to grind on both thermostat housing, iac, and removed both gaskets. I used gasket eliminator to seal it up.i know it sounds bad but worked well.

I guess a got lucky with the double roller timing chain, not having to grind the timing cover. I just couldn't get lucky enough not to have to grind this stuff for my nitrous or the windage tray and block for my h-beam rods
