Hello

[schulz464]

new to the forum. Looking for info on hooking up a mark IV block with port injection, any suggestions for throttle bodies, and lastly any harnesses readily available cheap.

Is it worth going to a Holley ecu or would a oem work?

I used a TPI computer and salvage yard harness for my Mark IV BBC project. One of the "Laws of Fuel Injection" ... The more you know about fuel injection, the less you pay for fuel injection.:thumbsup:

I figured out: How to custom program my own PROM Chip. I figured out how to use the TPI wiring schematic to modify a salvage yard harness for my Mark IV fuel injection system. Including the engine rebuild, my total cost was less than half the price of an Edelbrock Mark IV fuel injection system.:jfj:
