<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: TheNovaMan</div><div class="ubbcode-body">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. </div></div>

Pete, I disagree. My talks with Joe when I picked my TR2X for my ZL-1 build was that Joe worked at Eddy at the time. The ORIGINAL TR2X were staggered ports, as per Joe. Only about 500 were made in that configuration. Eddy then changed it to the even port design. Man Joe certainly knew his stuff. Too bad he's gone. He did tell me that he still thinks that was the best TR around until just recently.
