Post A newbie question about my Chevy truck

I have a Chevy 95 Silverado with a 350 that just rolled over 100K miles. It's starting to use some oil and my mechanic suggested a rebuild. Fair enough, but I'd like to put a few more horses under the hood while I'm at it.

So,,, the deal is this is a 4X4 work truck. Farm duty. Farm duty meaning 70% of all miles are on the highway running around and 30% being pulling serious loads, driving through deep snow, going in the fields when it's wet, etc. I'm not looking to build a street rod, just something with a bit more ompf when I step down on it. I *think* the engine was rated at around 240-245 HP when new. I'm thinking somewhere around 300-325 HP would be nice.

Any thoughts?

I'd get a crate motor, there are different HP levels with warrenty,cheaper that a rebuild.
Check out GM site.

Another Good Place for Crate Motors

But remember you can always go with a rebuild. But there are engines made specifically to replace your engine, meaning they have the wiring harness and every thing so you can retain your stock engine. It all depends on how much money you are willing to spend.

I took a look at the site you mentioned but all I seen were crate engines for earlier trucks. (All using carbs.) In fact most of the crate engines are more street performance oriented. Am I missing something?

No, you're not missing anything, Big Red. Most crate applications are for rods. It is possible to find something that will suit your needs, but you may have to check around some. I suggest you contact you chevy dealer and ask about Chevy Performance Parts #12497317, or look at Pace Performance Parts

<a href="http://www.paceparts.com/product.asp?0=239&1=241&3=948" target="_blank">http://www.paceparts.com/product.asp?0=239&1=241&3=948</a>

This is a factory crate motor that is a real torque monster. Unfortunately, it will not pass California smog checks so it may not work for wherever you are. There are other options, but as someone said above ... it all depends on how much $$ you have to spend.

Good luck and Happy New Year!!

Thanks Bluesman123, thanks much!

This looks like just what the doctor ordered! The biggest load I put on my truck is pulling a farm trailer and this looks like it was custom made for the job.

My mechanic gave me a ball park figure of $2500 to $4000 depending upon what I want to do. (I talked to him about increasing the HP.) Also said he could spend all the money I wanted to throw at it.

The thing I notice though is that this says for pre 1973 vehicles? Is that due to emmisions controls? (Not an issue as I live in the middle of nowhere farm country.) Would my existing "stuff" I.E. manifolds, TBI, brackets and such still work? (I'll call the company once the holidays are over.)

Again thanks, this really looks like the exact match for my needs. Heck I may even go pick on my brother and his big block if I get this installed.

Happy Holidays

you might actually want to look at drivetrain mods as well as a simple rebuild... horsepower isn't everything.
so... maybe at least look into either; an underdrive and numerically low gears, or an overdrive and numerically high gears.
the reason i suggest is what generally you build an engine for horsepower in a certain rpm range, while you're really looking at two very different applications with very different rpm's. a good pulling motor at low speed generally doesn't run quite so strong on the highway, and vice versa. with the gearing changes, you can stay in the power band either way.
... just my $.02.

There should be a crate motor out there for your application, keep in mind the computer that runs everthing in your truck, if you want to keep everthing running through it, make sure the motor is compatable, I did my 93 GMC 4X4 last year, it had a 454 that was rated at 290hp (very sad) I stuck with my motor, kept the compression close to stock, bored .030 got a crane cam designed to run on computer controlled vehicles, (duration was about stock but had more lift) I had to install screw in rocker studs and get new rocker arms since my heads had non-adjustable rockers, added a set of Hooker headers W/dual exhaust, installed a new computer chip from Jet (not the drag one, the one for low end torque) being it's a 1-ton truck, it didn't make it a dragster, but it feels like I picked up about 150 ft. lbs. of torque (especially when I'm towing) and I haven't had to make any other modifications.
Whew, that seems longwinded! Good luck.

If you want all the torque you can handle? turn your old motor into a 383! it is very easy to get 450 ftlbs of torque from this and cost not much more than a stock rebuild and if you do it yourself should be at around $2000? this should pull anything you can hook onto!

Do you really think so? My engine is turning right at 2000 RPM at 70 MPH. (Automatic with overdrive)

depends what you have right now... if you've got a 700r4 it probably makes less difference... i kinda missed the '95' part. <img src="graemlins/drunk.gif" border="0" alt="[drunk]" />
