period correct tunnel rams

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: pxtx</div><div class="ubbcode-body">With that criteria, I would say the Offy TP Tunnel Ram is a perfect fit.

In the 1980's my uncle put a TR on a street rod with a similar set-up. It has been the most street friendly dual quad car in the club and is still running strong to this day. You could dive it in traffic tomorrow, then blast off to Columbus without a hitch. Vac advance distributor with a special tune. The street rod is a 42 Ford pickup. It's not a race car, but has turned 14's at the drags.

My personal hang-up is having a TR equipped car only running 14's. </div></div>

Awesome! That's what we're going with then. We'll figure out the carb selection later, but I've been reading up your advice on SNS about using 2 600's. We want to have fun with this setup, and not have to deal with a finicky rpm operating range.

Sorry but all the intakes that I have pictured are manifolds that I have sold in the past. Just posting them for reference.

Marlin, you can buy them new from Offenhauser through Summit. I think I paid $380 for mine 6-7 years ago. Offenhauser still uses the original molds. Everything is 100% identical to the originals even the lettering.

If you buy used there are tons of them out there for sale but look them over carefully. These were race items and many are butchered up-plenums cut out, hogged out intake ports, holes drill in them for nitrus ports, mounting flanges milled down for weird head angles..that sort of thing.

Ok, sounds better.

I just got my tunnel ram combination running this fall. The long block is a 454 LS6 crate motor from the 80s with 990 heads and 10.2:1 compression. I put in a Crane p/n 134691 solid flat tappet cam (0.580/0.600 lift, 256/266 @ 0.050 and 290/300 advertised, 110LSA) and topped it with an Edelbrock TR2X and 660 center squirters with secondary metering blocks. I run an electric fuel pump and an MSD 6AL box. My torque converter flashes to 4000-4200 rpm or so off the line, and I have 4.10 gears. &quot;Everyone&quot; said it was going to be unbearable on the street, and I had my doubts too because of the enormous plenum, but as it turns out the throttle response and torque are phenomenal! The first pass was 11.39 at 118mph. The air/fuel ratio is fairly close for most of the 1/4 mile, but I need to drill out the accelerator pump squirters for the launch and restrict the idle feeds in the primary metering blocks for the pits and the street...

Early TR2X manifolds had equal-sized runners, but they went to the staggered runners around 1970 or 1971 (I think). Joe Sherman is a big fan of this intake. Grumpy ran it for a while, but then switched to Weiand.

wow that is good street times. keep with the updates!

That is cool and we need pictures.

This is an Edelbrock UR2X tunnel ram. I'm not sure exactly when Edelbrock released this manifold, but it was at least before 1976.







It has the unequal sized runners.



This is the same manifold (not the <span style="text-decoration: underline">actual</span> manifold, just the same model) I ran on the L78 396 I had in my first `67 Chevelle around 1983.



I used a pair of Carter Competition Series 750 AFB's back then, and the swap to this manifold from a 163 with an 800 Holley made a very notable improvement &gt;4K rpm on that little 396.

The current UR2X will eventually make its way onto the 496 in the current Chevelle project. I just had the 163 off of the 496 for cleaning and couldn't resist setting this in place for a quick pic. [img]<<GRAEMLIN_URL>>/grin.gif[/img]



If the manifold makes the same kind of improvement on the 496 that it made on the 396..... [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

I have some pics that are more up-to-date, but I haven't had a chance to upload them to Photobucket yet. In the meantime, I'll wet yer whistle with a couple pics from before it was quite finished.

Sounds and looks great. I like the VC spacers.
