  • Original center tube too close to the P/S rack for comfort? Or other clearance issue?

    • They were going on the blue car until that day I called you! My mind was fried from lack of sleep, food and energy drinks making me feel on edge (lol) and stress from the shift cable popping off the shifter that never came in these cars, and I had to talk to someone or loose my mind. The radio isn't hooked up either in the car and after several hours of just hearing the wind noise/motor hum I was going crazy. I forgot to bring my headphones or else I'd have all my tunes on my blackberry. I brought everything else !! Even a stereo cable to plug into the rental cars stereo to hear my music... I was going to call you before the trip but like you, when I would remember it would be too late to call.

      • I had to ding Alan's header and I made sure I put something on the jig where the S&S headers were beat to death. It was a bulge on the back of the trans that was in the way, and with me keeping the collector close to the passenger side, the assembled headers were tight getting into the car and actually broke the KS connector (that I had to replace

        Moving the middle primary just made them even closer to being perfect equal length too

        • On the orange car, there is TONS of room "behind" the motor. Nothing there but an axle.... it's strange seeing this big empty spot where I'm used to a bulging transmission pan hanging down!

          • I'll take equal length any day! Equal length rules, and is one reason why Gen2 intake manifolds suck (they aren't equal length), lets not forget!

            And these can be used with N2O, or a supercharger let's not forget! If I didn't already have 11.5:1 compression, a setup like mars_man has with the CSC would be damn sweet.

            • N BODY!!!!! LOL

              Actually early N-body fit, 4T60, with a 3500 head, and dont connect the collectors, I want my dual pipes. You don't think I could let this thread go this many pages and not stick in a request for parts on an Oldsmobile do you? :P
              sigpicHow to make High performance Emissions:
              A "true" High flow converter, straight pipe.
              Low/No flow EGR valve, block off plate.
              Carbon canister and purge valve mod, place in large 30 Gallon can, cover, and place curbside, the city will do the rest.
              PCV valve and vent tube, reroute to exhaust to dump where it belongs, on the ground. Or add breathers and let it all free.

                  • They aren't perfect equal length, but getting closer lol. <10% variance.

                    • Hell a lot better than the S&S ones. 10% that's close enough to call it I'd say! Not going to affect much with that small of a variance.
