As far as I know small block mopars do not benefit from a T ram like the big blocks do.





Back in '87 I ran an Edelbrock t-ram on the '67
Cuda. Little 340 with 10 to 1 and the Lunati
BR II cam, only .480 lift, 234 at .050 and ported
lightly 340 X heads. Two Holley 450 carbs.
Power range was 3000-6000 rpm and was real nice
to drive on the street. I could drive 150 miles
one way to Cedar Falls Raceway in Iowa and run
12.20's in street trim. Worked good 22 years ago
and they still work good today, all in the setup.

Interesting read that delves into theory & practice.

Back in the late 70s and early 80s I ran an Edelbrock str14 (tunnel ram with layed down runners) with a single TQ (tried some holleys too, they ran about the same) on an 11 to 1 440 in a 68 barracuda four speed car, 4.56 gears, hooker 1 7/8 fenderwells. Cam was in the 540 lift range, can't remember the duration. It would always start and run well and I street drove it almost every day I had it. It produced tons of low end and midrange torque. Ran out of breath around 6000 rpm. Would run around 11.10s and that was at 3000 ft elevation.

I have an article in the 2008 spring issue of hot rod do-it-yourself engines series magazine where they tested 18 different intake manifolds on a B engine mopar. It included an edelbrock str15 (the low block version of the str14) and it produced only average performance. I was surprised to see this since it seemed to work well on my 440 barracuda, maybe it's runner lengths and sizes are more suitable for 440. In this magazine article the clear winner seemed to be the weiand hi-ram tunnel-ram with the greatest torque and highest horsepower #s by a significant margin. Another intake that seemed to stand out as a good street performer was the dual plane edelbrock performer rpm.This article is a good read, find it and read it if you can. Interesting stuff.

Hey QuickD, what are the numbers on your TQ carbs?

My old DartSport had an M1 single plane and 1050 Dominator running in the 10 flat range with a best of 9.96 on a real cold day.
I switched to an M1 low deck tunnel ram with 2 750 Quickfuel carbs and the car was a whole new animal. It started and idled better in any kind of weather as long as it was over 35 degrees. Ran consistant 9.90's with a best of 9.88. Footbraked to a 1.36 60 foot, this was an 11 to 1 compression 451 with the MP 590 purple shaft solid cam.

If you don't mind I'll look tonite or tomorrow. It's -10 and my mess is out in the garage. I just don't remember off the top of my head. I have milled the airhorns off and installed replaceable bleeds on everything. I'm guessing they flow well past 900cfm each. Dave

It was -20 when I went out to start my work truck this morning.

In the early 90s Edelbrock made a "Street" tunnel ram for mopar small block. It was not as tall as a Weiand or the early Edelbrock units. They only made them a few years.


Keep old mopars alive.

thats what I run

everyone says my car should be a pig...
basic stock 360
mopar 474 lift cam
stock small valve heads
3.23 gears
eddy street ram w/ 2 holley 390's

I get 16 mph highway ( driven all over even in the rain)
run 12.56 @ 106 in the quarter ( 1.74 60' time )

I ran a stock cast iron intake on my car and a holley 780 it ran 13.2 @102 w/ 1.86 60' times
so the t-ram does work!

never have any driving problems with the t-ram, aside from looking at it shake in front of you at idle you would not even know its there..till ya step on it

Scott; The back carb is a 6322 and the front carb is a 6545. I've worked them over so they're a matched set now. Dave
