Check out thirdgen.org. They are into modding those motors plus have a few free tweaks that can be done.

 

I can't imagine a situation in which you'd be willing to spend the money and time to install a blower, but are unwilling to do an engine swap. Quickest and easiest-put a big block in it. It uses the SAME MOTOR MOUNTS, and has the same bellhousing bolt pattern. Hell, even the distributor is the same as a smallblock (though the tbi distributor won't have any provision for mechanical advance, but decent distributors that would work for a carbureted big block are a dime a dozen).

If you don't want a big block, you could easily swap in a 350, 400, 383 stroker, or some stroker bigger than 400 inches. Smallblock chevys with strokes longer than 3.75" (the stock stroke for a 400 smallblock) tend to make LOTS of torque, enough to get your truck moving. I'm not technophobic, but if you just wanted to make it easy, I'd go with a carburetor on either a big or a smallblock and avoid having to spend the money and time making the fuel injection work with something the factory never used it on. There are times when making injection work is the thing to do-this does not sound like one of those times.

 

didn't know it was a truck sorry . I seriously think you're best bet is to check out some tbi performance forums. I hope this isn't against the rules but fullsizechevy.com is a good eresource as well.

 

alright guys, ill check the other fourms. Thanks!

 

If you could stuff a big block in there might as well go with the 572.

I know a person that has 2 of them in a boat.

572 C.I.D. - 12:1 Compression Crate Engine
Horsepower 720 @ 6250 RPM
Torque 685 Ft. Lbs. @ 4500 RPM
Max. Recommended RPM 6750 RPM

Well I guess the question is.......how much are you looking to spend?? There are a lot of options to get some more juice out of the motor, but some of them options are cheap and some are really expensive.

hey I've got a MAF TPI 305 from an '86 IROC in my '56 chevy 210 sedan and I couldn't be happier with it for being a relatively stock engine. we just have the basics, GOOD homemade air intake, headers/exhaust and a little tiny Crane CompuCam specific for TPI engines.
if you're considering a supercharger, you'll be between $3-4k for a centrifugal setup with all the necessary goodies...and then a tune. and then you're blowing through a TBI unit, which I'm a big fanatic of fuel injection and I'd rather have a carb than TBI. I think if you want to keep it simpler than a BBC swap or something like that, get some good heads, a TPI setup and a cam. affordable-fuel-injection.com has the most inexpensive EFI setups I've found.
a lot of people rag on the 305 as being a little p.o.s., what they don't realize is that it's a small version of a 383. the bore/stroke ratio is very close to the same. the reason these engines get such a bad rep is they came with the #2 worst flowing production heads that GM every made for a v-8.
so, for the 305, since it's too small of a bore for the 2.02/1.60" valves, there are a couple of 'stock replacement' performance iron heads or the Vortec truck heads that have 1.94" instead of 1.86" intakes and I forget what the exhausts are.
1. is World Castings makes the S/R Torquer 305 for roughly $5-600 a pair. and you can buy a high flow baseplate for roughly $3-400 I think.
2. Scoggin Dickey Parts Center makes a high flow TPI baseplate so you can put a TPI manifold on Vortec truck heads. they sell that with new vortec heads with upgraded valvesprings and all the gaskets/bolts necessary.

so, for about $1k you can get good heads and a high flow baseplate(which is the most restrictive part of a TPI system) and then get the complete TPI from A-F-I for about $2k. then you're still in it for a little less than a supercharger and you have a very efficient engine with a bunch of low end and gobs of mid range torque that'll rev to 5,500rpm with ease. that's nice for a 4x4.
with that top end, if you get the itch down the road, you can put a 350 short block with a simple chip change in with no problem/headache. may have to change the injectors out, may not, would be a good question for the A-F-I guys.

I really really like S/C's and turbos but I'd choose upgrading to a TPI and good heads in a heartbeat before forced induction(that'd be next!) if you weren't in AR I'd offer to let you drive my '56 just so you could see the difference between EFI setups. I can't understand why they didn't use that for the 87-95 trucks, it makes so much low-midrange torque.

 

my wiring harness will only hook up to a 454 or smaller

 

2-3 thousand will be about all i dump into it


ive gotta get this thing like i want it so i can drive it when i have my dodge in the shop puttin on the twins

 

sweet! thanks, ill dig a little deeper into this

 

I agree with Jon and what he posted a couple posts above.....a super charger would be nice but you are lookin at around $4k give or take. Some kits are cheaper than others but don't perform all that well.

I'd do some new heads, cam, a little work to the injection system, maybe swap out axle gears too as a possibility......maybe some 4.10's??

These motors run really well with just a little tuning to the motor and some bolt on goodies......then after that's all done and later down the road you get the spare change, throw that super charger on and you'll be happier than a pig in doo doo!!!

A super charger will definetely give you power, but it might cost a few more bucks than you are wanting to spend.
