I am ready to bite the bullet and order the Trick Flow 270 heads for my 500" RB but after reading and reading and reading some more I just have no idea what intake I should run with them. The Super Victor doesnt line up from what I read and the Trick flow intake is to small of ports since it is designed for the 240 heads. I will be running a 1050 Dominator so would like to bolt it to the intake with out a adapter. Any suggestions would be appreciated.

Thank you, Matt

I don't know what to tell you but I used a Mopar 337 intake but used a 4150 carb. And 337 intakes are hard to find.

If you got the room the 2" 4500 to 4150 adapters work well.

21 views and no replies. That is a lot like what I found reading on intakes for these heads. From what I can tell Indy is prob my only decent option? Prob end up with the 440-3x. Anyone know how the ports line up with this combination?

If you have the super victor it can be opened up to MW size by sending it to Hughes. I recently asked this same question and was advised by Andy F. Good luck !

The Indy 440-3X manifold you mentioned is a big volume manifold for big engines. Unless this engine is going in a real light car and/or is gonna turn a lot of RPM, stick w/ the smaller Indy 440-3. That "X" on the end of the part number makes a big difference. It's big so your lowend grunt is really gonna suffer unless you're set up for it.

I was told 440-3X was designed after Indy got upset seeing their big Indy heads being run w/ the huge B1 intake manifold on them, so they made their own equivalent.

Maybe I dont need the X. I have a 12.5-1, 499 ci. 275 @ .50 and .660 Lift solid roler cam, 8" 5000 rpm converter, 28" tire and 3.73 gears. I was trapping befor at around 6300 rpm. I would assume i should be around the 6500 maybe + a little with the new setup. Prob wont be reving higher then 7000. car weighs 3750 with me in it. Currently runs 10.60's with the stage VI heads and am hoping these TF 270's willadd a little power over my stage Vi's

I definitely think the 3X is too big for your combo.

If you prefer a 4150 carb and have limited clearance to the hood, try to find the Mopar 337 intake. Otherwise go with a dominator and the Super Victor # 2893 intake, both those intakes fit great on the 270 heads.

Hood clearance is no issue and I like the Dominator seems to be very responsive. So the toss up is kind of between the Super victor and the 440-3 Intake. Anyone have any experience or know which one would be better for my setup?

I run the Super Victor on mine . It was the stock port , I opened it up to suit . No issues with alignment

I think the Super Victor is a better intake than the 440-3 but someone else might say the opposite. I used a SV intake on my 514 with Indy EZ heads. That engine made well over 800 hp most of the time and occasionally got into the 900 hp range.

Whatever you read was wrong. The Super Victor bolts right on to the 270 heads. There are two versions of the Super Victor, std port and MW port. You need the MW version for the 270 heads.

Your cam might be a little too much duration and not enough lift for the 270 heads. I'd recommend calling Dwayne at Porter Racing Heads and talking to him about your combination. You might pick up some power if you throw more lift at the valves. Not sure what Dwayne will recommend, maybe something in the 272/280 duration at 0.050 and 0.750 lift. Kind of depends which rocker arms you have and how much money you want to throw at the valve train.

I ended up selling my rockers with my old heads so I will be buying new rockers. I was told to definately get 1.6 with the lower lift cam and it would pick up power. I will have to buy a intake so it looks like I will prob go with the 270 heads and the super victor intake. Any suggestions on rocker arms? I was looking at the comp ultra magnums but don't see any 1.6 in them. Do you think there is any chance possible that this could be close to the 800 h.p. mark?

Couple more questions I just thought of. Any idea which version of the 270 head would be the right choice for me? Titanium retainers? The 1.55 Springs say good for .680 lift. Would that work with my .660 solid roller? Or do I go to the 1.56 with titanium retainers? Says there good for .700 lift? Also I am running a 75 cc chamber on my stage 6 heads and these are 78. Any idea what the easiest way to get the compression back up or higher? I have previously been running the Felpro 1009 head gaskets .039 Thickness.


Thank you everyone for the help. I have been wanting to replace the old stage 6 heads for a long time so I am excited I actually can. I tried to buy a set of Indy 440-1 off of Facebook page and got scammed out of $2200 a few months ago so I have been working late nights in the shop at home trying to get my money back together. Two months of after hours work in the shop that the guy scammed me out of. I decided I better just buy new and the 440-1 are more then I can afford new.

If your pistons are below the decks you can use a thinner head gasket to make more compression, I would shoot for a minimum of .035 piston to head clearances at the highest point on the highest piston edge .040 is safer though
On the rocker arms I like and use the Harland Sharp 1.6 ratio for all my 440 type heads with the single shaft rocker arm set up. They can and will make them in any ratio you want also at 440-238-3260
The big thing that matters is on any roller cam is having the correct spring pressures, call the cam company and get the pressures they want you to use

to tweak your compression you can use a thinner Cometic gasket, comes down to piston deck height . I have cometic 040s on now , but use cometic 027s on my 440ci stock block . Have used 270 heads on both .
As for which head , they seem rated per spring/cam type . I bought the hyd roller/solid ft head .
As for rockers if buying new buy the HS (?) specific for these heads . I am running Crane Golds 1.5s , wish they were still available in the 1.6 .

I should have said that my pistons are at 0 Deck height right now. As far as the cam I am not sure the exact brand as I bought it used and the specs I got were

Cam Dynamics Mechanical roller
Crane 8620 steel billet core
Part No. cdr274-06
core no 689356

278 @ .050
.660 lift with 1.5 ratio rockers
cam timing @ .50 intake opens 35 btdc, exhaust closes 31 atdc
Lobe seperation 106 degrees with 2 degrees of timing ground in

If you have the heads off the motor now I would have you check all eight pistons at TDC and use a small thin bladed screw driver to push down between the piston and block on the cam side first and rock the piston over towards the other side of the cylinder and check the height of the piston edge on that side(cam side), do the same by using the screw driver to rock the piston towards the camshaft on the motor mount side and measure the height of the edge of that piston on that side also
I've seen between .002 and .017 differences in piston deck heights at the edges of the pistons checking them that way, I had some touching the heads their with a .039 thick head gasket with zero deck height pistons is the only reason I found them

When i rock the pistons like that they all seem to be the same but they do possibly stick up above the deck surface a hair. They are basically all at o when they are flat. They dont rock much in the hole.
