I've searched around quite a bit and read all kinds of conflicting stuff from it won't work at all to Trickflow is coming up with a manifold.

I am under the impression that the Trickflow 270 with "Max Wedge Type" intake runners wil work with a B block if using an RB intake manifold.

Is this the case? If not what are the options?
 
This isn’t complicated.
With TF heads, you would use the manifold type that matches the block you’re using.
B manifolds on B blocks, RB manifolds on RB blocks.

The 270’s do indeed have MW sized ports, and afaik only Indy offers low deck manifolds with MW sized ports.
 
I think o.p. is thinking of raised port stage sixes, that could use an rb intake on a B block. Wont work on a Trickflow.
My question is.... can the trickflow B intake be opened up to maxwedge size? Is there enough meat?
(FWIW, I have a tm7 440 intake opened up to maxwedge. But the top of the port needed welding, and the bottom of the port is VERY thin.)

This must be what I was thinking, and had my mind mixed up. So it's a yes on stage six heads with RB manifolds on a B.

So now another question. Just how much meat would have to be ground off the B manifold? Couldn't a manifold be welded up?
 
Heck, I wasn't even sure TF made a B intake till a couple days ago. So I have no experience with how much metal is there, to know if it can be opened up to maxwedge.
What I do know, I described above. My TM7 has had a chunk of aluminum welded to the top of each pair of ports, to enable them to be opened to max size. The bottom of the port is okay, but bare minimum thin. Width of port seemed to be no problem.
What would have-to-be/could-be done to a 383 manifold to get it to match a 270 tf, I have no way of knowing.
As said above, the only bolt-on maxwedge B manifold I know of is from indy, and I don't know if you can even get one now.
I can post pics of my Tm7 if it'll help.....

Trickflow says their intake can be opened up for max wedge ports.
 
What is the action plan for the engine? Maybe the TF 240s with stock size ports will do the job, & you then have a LOT more intakes to choose from.....
 
Indy is really the only show in town for a b engine with 270’s

Depending on how much power you're looking for, The 240 intake will support 700 hp or so in a 270 head, I will be dynoing one in a couple of months, anyone want another manifold tested, and want to send it at the time let me know, I will have it for the day.

Any news on the 270 low deck setup? Been awhile and I'm sure things have been tried.

No first hand knowledge but the 1st hand knowledge I have is the 240s are too small for my 470
 
As soon as I get my car put together and have some room I'll be doing another project. Some welding required lol

I thought trickflow had a low deck intake. I would think that if they have common sense, it should be able to be ported to a 270 head.

That pic above is low deck but they don't make a 4500 flange
 
I've got a dominator flange m1 for a 440 that MIGHT be able to go to a 270 port (it's standard port now).
Did Mopar make a low deck dominator M1?

My guess is most people aren’t looking to reinvent the wheel with their B builds using MW heads, and use the Indy manifold……….since it fits.

I did a low deck 470 with TF 270 heads. This was a pump gas engine, made 780 hp with a Wilson ported Indy intake. Made pretty good power with a heavily ported Mopar 4500 M1 intake.

M1 4500 intake requires a lot of welding to make power on 270 heads. A lot of welding. Figure at least $2000 to have a pro cut the intake apart, add material and weld it all back together. Much less expensive to just buy an Indy intake and have it port matched.

Thanks Andy. I was just kinda wondering. I have a selection of intakes that I can use on a 440 with.a maxwedge port, (including a tm7 with "a lot of welding"). I was wondering if the MI dominator I have could get that big. I guess the answer is no.
If i ever do a 400 stroker with max heads, an Indy intake will be first on the shopping list, lol.
 
For a low deck the only option is Indy. For an RB engine you have more choices. Edelbrock, Trick Flow and Indy all have MW single 4bbl intakes. There are also cross rams, bath tub rams and tunnel rams available.
