Will this Holley intake work on a stock TPI 350?

I've got a stock 350 from an 88 GTA with relatively low miles that I am wanting to install in my 88 Camaro with a T5 trans and 3.45 posi. I have this Holley intake setup but I honestly don't know much about it or even what it is. I was hoping to maybe use it on the 350 in my car with headers and 3.5" exhaust. The heads/cam etc are all stock. Thanks!

Worth little on a completely stock long block. "10hp up top, 50ft lb loss down low" sorta thing. Heads and/or cam? Way worth it.

Yes it will "work" as far as the motor is concerned.

It points the TB kind of upwards, which will make it hit the underside of the hood. Probably wouldn't be that hard to make an angled spacer. I don't think it takes all that much to relieve the interference.

It was originally the "Street Ram", for 2 4-bbl carbs, introduced sometime around 1980. It had 2 little plenums that you'd then put the carbs onto. Didn't really catch on, was really more of a "looks" deal than a "go-fast" piece. I think was discontinued by around 85. Holley resurrected it around 89 or 90 with injector bungs and that EFI plenum on top instead of the 2 carb ones.



Essentially has been completely forgotten except by idiots like me.

"The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun.

Is there any thing whereof it may be said, See, this is new? it hath been already of old time, which was before us.

There is no remembrance of former things; neither shall there be any remembrance of things that are to come with those that shall come after."

Even the quote fits that description.

I think weiand dubbed theres the HI ram, edelbrock called theirs the street ram and imo a better tunnel ram bc the ports were bigger and offset lining up to the head better SLP used edelbrocks cast for there prototype streetram
