Complete build up. I used a 1973 block with .040" Over sized pistons. Gapless ring set. The pistons are flat top with 4 valve relier's. The top of the motor is 1993 TPI Computer controled HEI heads and Intake. With a 2 bbl throttle body injector system. 1.6 ratio roller rockers. I used an Paw Super Stock Industries cam #10338 performance range 4. Duration @ 0.050 Lift 230-230 Advertised Int Exh 284 284. Gross Valve lift .452 .452 Hyd.
The engine will idle in park between 1500 - 2000 rpm's. When I put it in gear it drops to 500 rpm's. If you let off the brake it will go, but when you give it the gas it acts like your not doing anything. (the linkage is working it does move the throttle on the carb) I have a 4 row radiator and I am useing a 160 deg thermostat and I have a dual remote filters with an engine oil cooler.

Can I make this system work and I just have a simple problem?

Do I need a performance chip for the computer?

Should I change cams to one that is for a computer controlled vehicle?
