Anyone use a Holley TB on their 91 TPI???? It appears that Holley does not make one that works. The IAC passage is wrong. What TB are you using????

Thanks,

On certain companies, such as overpriced TPIS, you attach your stock IAC to the bottom of your new TB.

1989 IROC-Z 5.7L
NOS 5151 150HP kit
ProBuilt 700R4, PI Vigilante 2800 stall lockup
Baer Brakes 12" Sport System

 

I know that, this is the way the ICA sees or controls the idle. The hole in the TB lines up against the plenum, sealed tight. So there is no adjustment at all.
