I bought this Holley aftermarket Throttle Body many years ago and I was asked if it would bolt onto a '89 car.

I don't see where the typical Holley112-xxx part number is stamped on here. The only numbers appear to be "11323 1 161 5"

Does anyone know if this will work for all years TPI? Or what should I look for to distinguish the years?

I plan on calling holley on Tuesday when they open, hopefully they're not shutdown for the holiday.

Thanks!

89-92 linkage but the iac passage does not connect between the bores. A hole needs to be drilled in the plenum or connected between the throttle bores. I’ve ran into this on a few holleys

Thanks for the reply, I'm not entirely clear about where the drilling would need to occur.

I do see a coolant passage between the two bores in the plenum, is this good?

Would someone be able to use PAINT or something to sketch where the drilling would be needed?

That’s a older 85-88 plenum it will work as is.
