Found a Holley TBI for $5........

[1project2many]

I don't know if the new design Holley TB is close enough to the old for the pods to work. If it does, then be sure to check for excessive throttle shaft wear (it allows air to leak in when the throttle is closed) before placing the TB into service.

Yes good call my friend. Actually when I was looking at this throttle body it is less worn out then all the stock GM ones. Probably never saw much if any use. I'll know later tonight if the pods will work.

It looks like it will fit. There are a couple of "nubs" on the bottom of the injector pod that will have to be ground off first.

I'm trying to figure out what the IAC thread is to drill and tap this TB. It looks to be a NPT.... I'm going to drill and tap a test hole to confirm that.

The link I posted...I forgot to mention that the op probably smoked the first fastener down then couldn't get the remaining two aligned/started so he said he had to enlarge two holes. That is false, three mounting screws align just fine.

Yeah more than likely lol. I haven't bolted them together yet, but the three bolt holes line up just fine. Really even two would be enough to hold it in place. The throttle body I ran on this truck in the past before I built this 355 for it was just that way. One of the three injector pod holes was stripped out. I'm excited about the prospect of using this Holley TB with a GM injector pod.

I have never seen one of these TBs in person until I stumbled upon this one. Man the throttle bores are massive compared to a stock TB.

What’s “Massive” are they really that big?

[stew86MCSS396]

Same as your bbc one in terms of bore size.
