ok im swapping a tpi unit on a 350.the motor has 10-1comp a tpis torque secrets2 cam ported and polised heads,big valves,ported upper and lower siamesed runners.i got most everything here and want to start only thing is i dont know if it will run on stock prom.i got a stock ecm for 91 sd car and prom without vats for ecm.i plan on getting a haltec unit soon i just wanted to knwo if it would run and maybe even be drivable.thanks for any info and advise.eric

 

It should run but I wouldn't vouch for it being drivable, you'd need to hook a scanner to it while attempting to run/drive it and see what is going on with the engine.

 

THAT is gonna make for a bumpy ride!

Your car's brain is gonna flip until you start burning some PROMs for it!!

 

yeah i figured it wasnt going to run the best.i just have everything except the haltec unit here and wanted to start gettin it together.wont have money for haltec for like 2weeks.i know its going to take about a day to get everything on.i just wanted to be able to start it and maybe move it out of the shop till then.if its drivable well fine if not fine.thanks for the input guys.eric
