Are/were there any cast B1 TR manifolds ever made?
The only thing I ever saw was a weld together “kit”.
If someone is buying a sheet metal manifold....... it could be sized for however big the motor is.

Agree. The intake is the one that Koffles or maybe Mopar Performance had made to go with the heads. It was a 3 piece intake. I bolted the runners to the heads and slide the plenum over them. Squared it up and welded. Runners were bell mouthed and funnel shaped tapering down to port size, made an open plate and attached a Big and Ugly on top.. Here is what I have.. The Indy intake looks almost identical to the Mopar Performance. Second picture is of a Big and Ugly hat on a tunnel ram. ![[Linked Image]](http://i.imgur.com/5W7qHea.jpg) ![[Linked Image]](http://i.imgur.com/48G65zl.jpg) Dave

In this pic of the kit....... it sure looks like some serious porting would be required to at least one end of the runners.

What is the total intake tract length? That is HUGE in power production. Second, what is the plenum volume? Third, what is the runner size in the plenum vs. at the flange and taper? All these things HAVE to work together to make REAL power. Your engine makes power, but it would seem even you are not happy with the results. I'm trying to make you look closer at the puzzle pieces to determine the problem. Or you can leave it alone...

I have one of those weld up kits. I spent many hours on the Bridgeport with that thing back in 1996. A very good B1 head guy told me to open the top of the runners to 6 square inches and taper it down to the port size. It ran the same on a 572 with two dominators on gas and with a bird catcher on alcohol. It made 907hp with the dominators. That was over 25 years ago can't remember the cam specs but I will try to find them. Good to know. Mine had already been worked on when I got it and since I have a friend who has one just like it with no issues I didn't think I would have any. Both are injected engines. Mine fit the ports perfectly when I put it on and I didn't think to measure the top as I wasn't expecting any issues. I'll check it next time it is off (maybe before) but the plan for the future is to build an new one. Thanks for the info on yours.. Dave

Even back then I thought mine should have made more power and always wondered how a good manifold would have been.
