Yeah? You went through the trouble of researching to see if you could get the EVAP to work properly, just do the cats and see what happens. If you had something like HPT you could do a performance tune and an inspection tune if necessary. Hydrocarbons is about the fuel trims and overlap while the other stuff is based on timing and whatnot, right?
Also since your car is an 87 the LS1 should run cleaner than the original TPI and since it is older the margins should be higher than for a new car anyway. I wont be doign a cam with my swap but I fully expect it to run a lot better than the TPI ever did.
