Hey i have a 1987 IROC. i bought a 4-bolt main 350 and bored it out to a 358, as well as milled the heads. I plan on installing a bigger cam with a lift around .450. I plan on keeping the TPI setup, and might be eliminating a few sensors, as well as emmission stuff to improve performance(any suggestions/tips/advice/etc on this would be GREATLY appreciated!!!) and i was wondering what kind of programable-ECM i should consider purchasing that will work with my setup. thanx a bunch
