Cool Engine swap for Blazer S10

I have an 87 Chevy Blazer S10 with a 2.8L. It's a very screwed up engine. (The guy who put it in forgot to do the finishing touches, to put it nicely)
I'm wanting to redo the WHOLE truck, engine, exterior, interior, the whole shabang. My question is this:

I would LIKE to put in a bigger engine for better HP, torque, and performance. I would like to put in either a 305 or a 350. Would either of those engines fit? And also, what size/model of transmission should I put in with the engine? I have the 700R4 at the moment. Also, to enhance the engine I put in, what would be the best bet with throttle body, fuel injection, or carboratur? And should I bore and stroke it out? Or leave it the same?

Any help on how to revamp the ole Duck Truck would be helpful! :p

There's tons of info out there on putting small blocks into an s-10. My friend had a s-10 blazer with a 305 TPI and it was pretty sweet. I'd say just do a search on the web there's probably tons of pages out there to help ya out. Check out chevyhiperformance.com they had an article about it a few years back like in 99 i think.

i you are seriou about it there are v-8 swap kits you can get for blazers and they are pretty cheap..also i am building an 88 s-10 right now and we are putting a fuel injected 350 crate motor in it...crate motors are a good way to go because they are fairly cheap,,,they are waranteed ,,,and they are pre assembled...as for the fuel injection part ,,,if you want to do it good i would go with multi port fuel injection all of this u can get out of a JEGS,,,or SUMMIT magizines and u can get the magizines free online

Its definitely a big job but it is doo-able, and sort of fun if you're a real wrench head. I'm almost done (I hope after 3 years) putting a 98 vortec 350 into a 91 Sonoma. There's lots of help out there. I STRONGLY suggest you visit this web site.

<a href="http://www.jagsthatrun.com" target="_blank">http://www.jagsthatrun.com</a>

This guy seriously knows what he's doing and sells the conversion stuff you'll need at a fair price.

Also check...

<a href="http://users.apex2000.net/whardie/index.html" target="_blank">http://users.apex2000.net/whardie/index.html</a>

and the many posts on this BB that relate to that topic. Before you make any major comitments of $$ you might check back and see if we have any advice.

Good Luck!

Oh by the way ... your tranny probably won't work. GM used several different bolt patterns and builds of the 700R4. Check with the Tranny-Rear End part of this board for more info on that.

I did the same swap. I have a 1987 Jimmy that was a four wheel drive. I replaced the tired 2.8 with a 350 engine and 350 tranny. The conversion was easy. I used old parts that were laying around me garage. If you need parts let me know. The results are great, the truck itself is very light but the only problem is handling is kind of rough. Good luck

Cool

Hey thanks for all yalls opinions and replies.
I'm still doing some major thinking. I still can't decide if I want the 305 or 350. Which one provides better HP???

I've done a lot of research so far, but there is still more out there that I want to look at. I know that I am going for top knotch precision, so this project MAY take a few years, huh? LOL.

It's pretty bad... I bought the truck for $3700 and had to turn around and put in another $2000 for an engine that was assembled poorly. To date, I have OVER $10,000 in that truck!! I might just put that much more in it because it is a sentimental truck.

If yall have any more info or suggestions on how I can redo the DT, let me know

PS: I'm not a "Big" wrench head just yet.. I'm still learning all my engine stuff, but I definitly know what I want!

If you need V8 swap info go here. <a href="http://www.v8s10.org" target="_blank">www.v8s10.org</a>
Or
If you want something differnt why not try a Camaro 3.4? It's almost a direct replacement for a 2.8 and has more power too. Here is some info on that. <a href="http://forums.s-series.org/viewtopic.php?t=52" target="_blank">http://forums.s-series.org/viewtopic.php?t=52</a>
Quite a few people on that forum have done 3.4 swaps.

Id go with a 350 over the 305. My 79 camaro felt strong with a 305 but when i switched it out with a 350 it was a whole new animal. 350s feel way stronger than an average 305. Not to say that you cant make a 305 strong, they too can be beasts. 350s are just easier and cheeper to get hp from. Both should red line at around the same rpm.

You have to go with the 350. It's much easier to get those up to 400 or 500 HP. Have you thought of putting in a manual tranny like a muncie M22 or a Richmond 4 5 or 6 speed. I have a Richmond 6 Speed and that thing I love to pieces. But definitely go with the 350. You'll thank us in the end.
Good Luck

Talking

I'm seriously thinking about putting the 350 in with a 350 tranny. My boyfriend just got an 83 Chevy Scottsdale and it has a 350 in it. Unfortunately he went to jail last night and well, I had to fire the truck up. The tranny it has in it now goes to a 305 (don't know how that was pulled off) and it's about to go, but that truck has so much torque. I love it.

I'll check out those sites you all gave and give it a lot of thought, but I've made up my mind, I'm putting a 350 in it!!

Thank yalls Keep replying!

93 s-15

Any v-8 will fit in as-10 whether its a 305 or a 350. You will have to buy special headers or if you have the machinery you could build them. The steering box has to be routed around. I had a mechanic tell me that the turbo 350 was the best and easiest transmission to use. If your planning on racing it I would check into a rear end swap also. I know the older camaro rear ends will work. And last but definately not least if you use fuel injection you'll need the wireing harness also. Personally I would go carburator but thats me. Hope I helped you out

Bluesman recommended you go to Jags that Run. This is the best advice on the planet. You want to purchase these two books:

Chevrolet S-10 Truck
V-8 Conversion Manual
http://www.jagsthatrun.com/Pages/Che..._S-10_V-8.html

Chevrolet TPI & TBI
V8 Engine Swapping
http://www.jagsthatrun.com/Pages/Che...I_TBI_V-8.html

This will be the best 50 bucks you'll ever spend in your life. Follow the recipe, all you've got to do to build a winner is just take your S-10 and these books then "shake and bake".

it's not hard at all to swap in a sbc, I would go with a 327 and a 700r4 though... It'll have more than enough power and still get respectable milage. You can use the driveline from a 4.3L s10 and just bolt on a small block- they have the same bellhousing.

v8 swap

I just did a swap on a 84 s10 from 2.8 to a 94 350 TPI and a 700r4 and love it. I went .060 and the torque is unbelievable and milage is great for a dd. I have the JTR manual if you need it. the swap is fairly easy but you definitely need to do research first. I choose the 700r4 tranny so I would not have to cut the driveshaft.I also went with an after market harness because 1: I suck at wiring and the 2.8 had a computer controlled carb. I would suggest that because I only had 4 wires to hook up. Also the corvette radiator is the best. I went thru 3 of them before I solved my overheating problem. If you need help let me know and the best site I found is the one that was said up further in the post: www.v8s10.org it is dedicated to only s10 and Blazer swaps
