![]() A bit expensive really but nice one piece intake design that cures the issues with TPI intakes. Which is pretty much a LT1 intake designed for TPI. Best intake for TPI in my opinion is the TPIS miniram. ![]() heads flow practically identical numbers and the cam was almost as similar. The Key reason the the 88-92 L98 350 TPI motors made 245hp and the 93 LT1 made 275hp is that intake. EVERYONE needs to read so I might need to move the edelbrock up a notch to my most recommended intake setup for a TPI engine. If you want good horsepower numbers from your car that intake has to go. Changing runers can help some but still perpetuating that long runner torque only design. In a jeep or 4×4, great low end torque although still 8 places for vacuum leaks. with a base intake, a plenum and then 4 long runers giving 8 problematic places for vacuum leaks and those long runners just kill any top end power potential. Just reminds of another of GM’s screw-ups and poor design. Next is that intake manifold, for some reason people seem to like the looks of it. I recommend you get a block off kit off ebay and remove the thing and tell me when you order a chip so that I can program the chip to run with the other 8 injectors and that will solve a lot of cold start issues on these cars. The worst piece on the whole TPI system is the cold start injector or referred to as the 9th injector.
