The main reason for the swap is the TBI, FI is is almost a necessity off road, there are times when my vehicle is almost vertical, the carbs don't cut it then. I am well aware of what needs to be changes to get the SBC in the jeep, its almost done and about as easy a swap as you could do. but is there anything that i would want to up grade to sneak a bit more performance out of it. i have to replace the TBI unit, should i stay with the stock unit or upgrade it?
