A few short questions on superchargering recommendations

[jack46]

I presently have a 383 SBC in my Z, and I am considering an upgrade. First I will be changing the suspension (9" Ford, tub, and ladder bars), then the engine. I can either build my 383, or use my LT1 from 93 Camaro, I have the full wiring harness, and a Vortech supercharger.

 

I have an effective stall of ~2500 and 4.11 gears, and my goal is >=400 RWHP

 

From what I have read, the 93 fuel injectors will be the first problem because of insufficient fuel flow.

 

1. Are the 93 Injectors too small for 10 - 12 lbs boost?

 

2. I prefer to use stock pistons (to save $$$), but is that being penny wise and dollar foolish? Or should I use forged pistons, and lower CR to <=9? (especially since juice might be added--no HP ever seems to be enough)

 

3. Will a reprogrammed chip handle the engine with an LT 4 Hot Cam without continual black smoke or other problems?

 

4. Should I sell the LT1 and simply build my 383?

 

I have received conflicting advice from friends and other boards. Some say a MAP won't ever run right, others have said no problem with a chip. I wish I had a MAF but I have a MAP, and don't want to invest more $$$ into a setup that is doomed to fail, or perform poorly.

 

Thanks
