[geneo4116]

HAVE A 27 COUPE WITH A 350/350 TURBO 220 STALL 9. 5 TO1 PISTONS,202 HEADS,THUMPER CAM,PRETTY MILD STREET MOTOR, MAYBE 300HP, RUNNIN SINGLE 600 HOLLEY PRO FORM,RUNS GOOD,JUST LOVE THE MULTI CARBS,WHAT SAY U, WOULD RUN BETTER ON THE STREET,TRIPOWER OR CROSS RAM

 

[Willowbilly3]

I vote tri-power

 

[CR55]

Tri power.

 

[jfg455]

tri power would probably run better but the cross ram would be different.

 

[grunt]

I like the look of the tri power...

I really like the 6 pack but, it's dobe a lot. The CR would set you apart. I don't think the HP difference will be that radical. You might do a little better on Gas with the Tri set up.

Based on visuals, I like the 3X2.

I have never ran a cross ram set-up, but it seems you would lose a little throtle response with it. That set up is usualy a race set up where bottom end response isn't a necessary!! The tri power is proven to work well on the street, especially if you have the proper linkage!!

I vote 6 pack!!!

Crossram or Tri Power

How about a Tri-Power on a Tunnel Ram? Haven't seen that yet.[ddev

Here ya go :

I love multiples...

But...

For performance, you would probably be better off with a single 750 double pumper.

As we've discussed before, nothing runs better than a single 4 barrel on an engine (well, maybe fuel injection, but that is a different story altogether). BUT, nothing looks cooler than a few carbs sitting on top of an engine.

When I changed from the single 4 barrel on my 23 to the 2 x 2 Vintage Speed setup I did lose some smoothness, but I sure liked the looks a whole lot more. My 27 has only had a 2 x 4 setup for the 20+ years of it's existance, and that will always be there.

So, my vote goes for the 3 x 2 setup for your car. Crossrams are really not all that bad on the street, I have seen a few and the owners say they perform well, but I think the 3 x 2 would be a little easier to tune and maintain.

Years ago, either Hot Rod or Car Craft did a manifold shootout. A single plane manifold worked the best. The tri-power was down on power, but the crossram was difficult. They noticed a fine mist above each carb at idle. Turns out it had a reversion problem. They tried building anti-reversion dams, which helped, but didn't cure the problems. My buddy tried a crossram on a bbc and had the same problem. He went with dual quads. My '32 actually ran better with tri-power than the single Edelbrock.

I have always felt volume is the problem with the cross ram, as I said earlier in this thread, it could cause it to lose response. Moving that much air rapidly could be a real chore!! But once you get it moving it works great!!

Not very streetable IMHO!!!

3-deuces

A 27 with 3-deuces just goes together. A 27 with crossram looks as out of place as the new shoebox kits that are mounted on the T-bird bodies.3-deuces are my pic and you can make yours different by coming up with a different air cleaner system than everybody else.

i dunno man. i knew a guy years ago had a nice 29 R.P.U with a 413 max wedge motor and those LOOOOONG factory crossrams that put each carb over the other sides valve cover and it looked KILLER. for streetable on a SBC though, i think i'd go 6 pack.

To me thats the only motor that looks right with that set-up!!

But you're right it's killer on a wedge motor!!!

Tri Power

I like it. How well did it run?

 

[Flipper_1938]

I think crossrams or more impressive when you open a hood and find one.

Just sitting out in the open, they don't really have eye appeal....not like a tri-power, tunnel ram or blower.

 

[26Troadster]

take the cross ram and make a new top for it with 6 2jets or 6 2 g's make 4 of them dumbies and run on the 2 middle carbs then you will have something different.
