You'll have to have mpfi heads, wiring and ecu.

+1... The SPFI shorty and the MPFI are the same compression... but as said the MPFI requires the 4 port heads, and related wiring... might as well just drop the entire engine in while you're at it... I also might point out that there is VERY little power gain.SPFI -> MPFI :dead:
