  • GM TPI parts

    I know this is a long shot considering how this is supposed to be a Ford forum but does anyone here have an aftermarket lower intake manifold from Excel, Lingenfelter, Edelbrock, or TPIS for a GM 350 with a tuned port intake?

        And it never will be with a TPI set up.

            All I could get out of it is a 13.4 and I wanted a little bit quicker. I'm not really worried about squeezing every last horsepower out of it. It's top speed is pretty respectable. I just bought it because it was the fastest car you could buy the year I got my driver's license.

              I understand, I just couldn't do it to myself.

                Believe me I know what you mean, when I was haltech dealer I installed an E6 GM on a guy's f-body and tuned it for him. TPI Motors are tractor Motors. If I recall correctly this thing was making about 700 horsepower at 5200 RPM and a lot of boost. The torque Peak was somewhere in the 4000.

                    Probably 2000 or 2001. I don't remember the guys name, he was just a customer.

                    Edit: Judging by your response this was an unusual power number to get. To clarify this was a number achieved on an engine dyno and not a chassis dyno. I did the tuning at Johnson machine on Metric Drive street avenue whatever in Garland. I didn't know much about Chevrolet's back then so I consulted with a tuner that told me what they needed in the way of ignition timing under boost and the rest was easy to figure out.

                        I used to work at a ton of different shops. The last one I worked at before I quit the car business was rotary performance. The 700 was on a superflow Dyno, not a chassis dyno. I'm also going purely from memory but I recall this combination having over 800 pound feet of torque at some point in the power curve. I remember being very impressed.

                        I tuned a 383 small block Chevy once that had a carburetor and a plate Nitrous system that made barely over 390 horsepower that had close to 900 pound feet of torque at one point. Since I was used to tuning very small but High horsepower engines back then that number blew me away. This was on a Dynojet at Rotary performance. The engine I'm describing was installed in a C10 pickup truck that I believe ran in the tens if memory serves me correctly. It had a very loose torque converter so that may have affected the numbers that I got out of it.
