I am now getting rid of my tunnel ram, and going with a fuel injection setup, and want a supercharger. Not a roots type, but something under teh hood. First off I am a complete novice when it comes to this stuff, so please forgive me if my questions are basic. My motor now is a 383, sbc, and I have heard that with a little more compression, and a little less boost the motor will have better "driveability" than with less compression, and more boost. I am looking for something around 550-600 horsepower.

Here are a few specs.

.030 over 350 4 bolt block.
Forged TRW pistons.
.500 intake, .518 exhaust, duration at .050 232intake, 242exhaust.
108 lobe seperation
Edelbrock RPM Alum. heads, w/ porting and bowl work. 64cc chambers
10.63 Compression

I believe I need to lower my compressions some, with maybe some different heads? So any suggestions on what fuel injection unit to use, and any supggestions on a supercharger? Will I need to change my cam?

Thanks for any help and direction you can give me.

With that power goal I'd recommend a P1SC. Will support that and more easily, and builds boost quickly. The cam should be swapped, the lobe separation should be around 114 or else you'll build less boost and later in the rpms. Compression also should be dropped to 9 to 9.5:1 for that power goal on pump gas, and heads with a bigger chamber is the easiest way to do that.

As far as EFI I like the FAST and BigStuff 3, but neither has complete kits. However Frank at GP Superstores can put together a package deal. If you go a different route on the EFI make sure whatever you choose runs a wideband O2.

Thanks Jody,

In quick ROUND numbers, Blower set up, $2500 to $3,000. FAST XFI complete FI conversion set up complete, $4000 to $4500, set of heads, $1500 to $2000. So you will spend $8000 to $9000 for the entire conversion.

Keep in mind these are quick round numbers.

Jody is correct. We can sell you everything and spec out all the critical components to be certain everything works togther. You should be able to make 600HP - 650HP without breaking a sweat!

If you would like to talk more, email ProdigyCustoms@aol.com, or call four zero seven 832 1752

Sorry my typing skills.

No F1, but F.I., Fuel Injection.

Frank set me up with a Holley Stealth Ram, Fast XFI, and Procharger, and some other goodies.

No problem, I misread it. Which model blower did you end up going with?

I got the procharger P1SC.

Frank said should be good for 600 HP. Thats should be good for a long while.

Yep, great blower. It's actually good for 600-650 rwhp or more, so more than you'll likely ever need.

Good choice, and thank you to Frank.
