BB Tunnel Ram Setup

[YENKO DEUCE REGISTRY]

How would this work on a 427 with oval port heads, 550 / 550 cam? I don't know a thing about rams, but I think it would look cool on the Day 2 car - is this setup period correct?

I haven't seen too many vintage TR for oval port heads. Do you have a line on one? You can open the area up pretty well so the transition form a TR square port isn't too badly interupted with the smaller oval port. I like the TR with the old breadbox plenums. They look really cool on a Nova!

From very early on, I've run 2 Holley's and a X-ram on my 65 daily driven everywhere. Highway or around town with 4.88's I get 12 mpg. If you want to run dual-quads- then do it. With a good tune (and there are some tricks to do) you'll be happy with the way it drives. Heck I didn't know that mutch at 16 and I did it. Sure it can always be optimized some more, but I would rather see Benjamin driving the car with what you have, than waiting for the day you find the ideal parts.

As for the mild cam, I don't see it hurting anything. What gear do you plan to run?

Carburetor selection will play a MAJOR role here. Two of the Edelbrock Thunder Series Carburetors with easy-to-adjust Secondary Air Valves (only requires a small screwdriver!) would be a great choice here in the 500 CFM, or maybe even the 625 CFM size. Both Edelbrock and Weiand make oval port Tunnel Rams with slightly downsized runners and smaller plenums designed with street use in mind. Don't forget that Edelbrock recently released a Dual Quad Air Gap with part #'s for either oval or rectangular port Rat Motors. I've actually purchased one of these intakes for my own ride because I'm a huge fan of the mid-range torque that a dual plane manifold provides. Now I've had some fast stuff but for whatever reason I skipped my "tunnel ram phase" in my younger years but I'm gonna make up for it now. As tall as it is, I'm gonna add a little more height to it with 1-inch tall, 4-hole carb spacers and probably the K&N Velocity Stacks that utilize filters. I also plan to grind off the "Edelbrock" script and do a few little tricks to make the intake looke a little more vintage. These Dual Quad Air Gaps are actually very reminiscent of the very tall Z-11 intake that came on the factory Drag cars of 1963.

Here's a pic. Not trying to change your mind or anything if your heart is set on a T-Ram but just throwing out there a little more streetable alternative. Edelbrock Thunder Series #1805 (625 CFM) are already pre-calibrated right out-of-box for this particular manifold on BBC's.

You're right - that does resemble a Z-11 intake.

I vote for the TR2-X,

i also have a big block and was thinking of doing the same. i would use either a weiand oval port intake number 1981 or edelbrock street tunnel ram. i was looking at these carbs

a friend ordered some carbs for a blower engine. when they dynoed the engine the operater said the carbs were excellently calibrated and didn't have to change anything. mike

To be period correct, you've got to run a pair of Holley carbs. Edlebrock's weren't around any any close equivalent is just lame IMHO.

This is the empitome of 1970's day 2 TR's. This is a Weiand, but I don't know the model. It has a pair of 450 carbs, but the ol' 1850 600 cfm are cheaper and easily tuned for this application. I run them on my 327 too.




There is something about the way this intake looks that I really dig more so than the Two Lane Blacktop set-up.

are those 450's or 660 center squirters?

There are no 660's in the three pictures above... The 4224 has a very distinct look.
