Just got this yesterday and looking it over noticed plenty different. Hope Tyler pipes in.

Air horn:
Missing the two solid tubes that connect to the cam covers.
One large solid tube that looks like it goes to the breather box.

No dedicated boss for IAT, just mounted directly in.
Has some stamps on it that I cannot decipher.

Throttle Body:
Already have one of these, and strangely enough, the SN is one digit off from my previous one.
Bottom sticker reads "Rochester Products: Product Engineering Experimental Sample".

Primary bore throttle stop isn't in the same location.

Primary bore throttle shaft is not the same length.

Plenum:
No fittings or provisions for coolant to come up from injector housings.

IAT sensor located on Passenger side between runners 4 & 6.
Two vacuum nipples between runners 5 & 7.

Phantom boss on the bottom, no idea for what.

Brake booster vacuum tube and fuel pressure reg vacuum fitting are different.

Vacuum tube off of drivers side part of the plenum.

No "4 CAM 32 VALVE" etched on the plenum.

My previous decision was to refinish them in the stock color. But now I'm thinking leave it in it's current condition. Mount it up on the wall more than likely.

Cliff, I've talked with those guys, this is not the plenum they had. The one they had was a 89 set up. There is no date stamps on this one. I'm hoping Tyler or somebody else can give me more insight.
