Re: questions for converting to TPI

Sorry should have mentioned my engine combo. My 350 has a mild cam and flat top pistons.020 over. My heads are mid 70's big valve smogers (not the best I know). the engine is about 9.5 to 10 -1 compression. Im Using a Moroso windage tray, Im running the stock 11inch flywheel.
it has long headers and 2.5 inch exhaust. Rear end is soon to be a 4.56 ratio. right now its a 3.90. rear tires are 295 50 15's
Im going to be changing the cam to work with better with my combination. I have no idea what the specs are on it cause I lost the damn cam card, but I know its very mild, about 17hg's at 600 rpm
With my combo will I need more than 22lb injectors?
