I am reading all on FI from these forums and other things, and I am wondering whats everyone opinions on FI for ours cars. The LSx style is waaay too expensive and a pain so ive been reading on the late 3rd gen style of TPI and the LT1/4 style. Which does everyone think is better? I read ultim8's write up on TPI he did and its very interesting. Is the Lt-1 worth it, or is a roller cam 3rd gen TPI set up any good? It seems like I can get a roller cammed 350 block and use an earlier style TPI set up and convert it to the MAP sensor type and use early small block heads and make some good HP. I dont know, is the lt1/4 style TPI any better? My concern is for upgradeability. They make superchargers for both styles, and I am wondering if the heads on lt1/lt4 engines are going to be good enough to make good HP and compete with a good set of AFR heads you can get for a normal small block. How fast do you think you can get an lt1 to? I imagine with a good cam, ported alum. corvette heads ( i think theyre aluminum ), and free flowing dual cats and good intake you can get some decent hp. And with some money you can build up an LT1, stroke it out, get some higher ratio rockers and ever supercharge it right? Im just waiting on a deal on a lt1/t56 to fall in to my lap one day for a swap, some junked up hit 96 camaro or something.
