Hey gang,
I'm a newbie here and wondering if I could get some advice on injector selection for an '89 5.7L TPI engine I'm building for my '87 Monte. So far the engine mods are as follows: bored .030" over, 9.75 compression pistons, bushed SCAT rods, SCAT crank(balanced the assembly), Comp cams hydraulic roller K08-502-8 .495/.503 lift 112 lobe sep, Pro-magnum 1.5 ratio roller rockers, MSD pro-billet distributor, MSD coil, MSD 6AL, BBK underdrive pulleys, BBK 52mm throttle body. I'm running Edelbrock TES headers with a Pypes dual cat back 2.5" system.
For now the heads, intake, runners, and plenum are all stock. I'm going to have to fab an air intake system obviously. I've got the stock multec injectors now but figure with what I've bought so far(and read about Multecs) they should be swapped out too. Any advice you guys can offer would be greatly appreciated. I'll need to know what prom mods I'll need too and where the best place to get one burned. Of course I can't run VATS either, but I have a chip that deletes that already because we had this engine in stock form in my brothers '81 Chevy Stepside! Any guess on estimated HP just for kicks? Hopefully this thing will be at Atco by late spring/ early summer, something tells me it'll beat my stock '88 Monte with 195k on it!

 

Looks like the FMS 24 lbs/hr would probably be about right.
