Holley TBI adapter

[PJG1173]

what are you guys thoughts on this adapter? I haven't been too impressed with the way the transdapt 1/4" plate style adapter fit. matter of fact I had to use a spread bore to square bore adapter to make my adapter work where the intake wasn't blocking the throttle blades. is this a better alternative? I can get one of these through amazon for $50.

I've liked all the Holley adapters I have used over the 1/4 plate adapters! More money but at least they are machined straight not just a flat piece of metal. The flat 1/4 inch metal adapters I use a gasket and sealer both sides to avoid vacuum leaks.

Also make sure to mount your TBI with the bolts your going to use and snug them down and make sure none of the bolt protrudes through the adapter, hitting the intake causing it to separate and cause a vacuum leak. Get shorter bolts or use washers.

thats what I'm afraid of... I check for vac leaks all the time since it started to warp just from tightening the adapter bolts before I even put the TB on it. yes I also not happy that I had to shave the TB bolts to keep them from hitting the intake. I am not a fan of using rtv on things that come in contact with gas, so i just used the gaskets that came with the adapter.

Sensor safe gasket sealer both sides of bottom gasket, light coat, wipe clean inside after tightening up, let it dry overnight and it will be fine. Top to TBI I don't like to use sealer but them dam 1/4 plate adapters it's just about mandatory... you'll have way better luck with the Holley.

Thats the adapter I am using. I have not had any problems with it, and it fit like a glove. Its roughly 1/2 inch think if I remember correctly.

Yes , the Holley is about 1/2" thick and it is of good quality .

I bought one a while back , it worked out good .

For some of the latest ones I have done though , I have just made my own.
