got aluminum heads with torker intake on the 455
Question is what needs to be done to the hood to use the OAI air cleaner setup

Throw it away and get a different hood. The Torker does not work with the OAI hood. You can get a repro air cleaner adapter and cut it up to fit, but there's nothing you can do to the hood.

 

Hi Rick
I don't think its huge on performance, but I've been told the older O4B aluminum intake will fit under an OAI air cleaner/hood setup. That's against factory cast iron heads, I don't think the aluminum heads would be any different but I don't know for sure. If you have factory OAI parts I wouldn't do anything to modify them, they're too rare and worth to much $$. Joe did mention the repo ring that doesn't have a flapper door in it, just the outer ring with the foam seal. That will shorten it some but I don't know if that's enough to use the torquer. John

 

I ran an O4B on the 455 in my Delta, I think it was the the same height as stock.

 

It's not, but it DOES clear the OAI hood and air cleaner adapter. The foam gets crushed a little more. Note that the O4B comes in two flavors, square bore and spread bore bolt pattern.
