My '84 S10 350 Poncho powered truck...
 
Here's a little budget build I've been working on lately...

1984 Chevy S10 with a mild 350 Poncho (72cc heads, performer rpm, little cam etc.).. Stock A-body motor mounts from a '72 Lemans, Milodon 7qt. oil pan and cut crossmember.

It'll have a TH-200r4 trans and shortened 12 bolt with 3.73:1 gears...

x2 there is nothing better than a poncho in a chevy!!!

Tastefully done. I like your attention to details. Nice job. You saved that trucks life.

Donovan 02-21-2012 06:05 PM

fun!

Lightfoot 02-23-2012 01:42 AM

Nice work.
You should find some S-15 badges to put on it. Pontiac engines are right at home in a GMC.

se428bandit 02-26-2012 01:58 PM

Looks nice, i wanted to build my S-15 that way.

RUDOLFSSON 03-29-2012 09:25 AM

Here's some fresh pics... Need to get the front end up next.

DennisG. 04-15-2012 04:01 PM

Nice little truck. Can't wait to see it when it's finished. I had a S10 blazer 2 wheel drive 2 door that had a small block Olds in it. Done up with a Bravada grill and interior.

'ol Pinion head 04-15-2012 04:27 PM

Looks sharp!

What front springs did you use?

455Grandville 04-15-2012 06:52 PM

Niiiiiiiiice

Stuckinda60s 04-16-2012 07:06 PM

Nice, better than new!

RUDOLFSSON 05-04-2012 10:47 AM

Thanks guys... I have 4 cyl springs in it now.. yikes!!! Will do an upgrade later..

Anyone have or know of a 82-90 GMC grille?!?! I'm looking for one :)

Sidponcho 05-04-2012 12:50 PM

Nice build!!!
I know its a preference thing, but a 5 speed would be so much fun in that truck!
I had a new 83 GMC S15 Gypsy with a 2.8 and 5 speed. It was a fun truck. Yours will be a BLAST

KARGUY 05-04-2012 07:51 PM

Nice project!!

What was cut on the crossmember? Also, what application did the exhaust manifolds come from? Was the steering column modifed?

Thanks for the pictures!

Karguy

RUDOLFSSON 05-05-2012 07:09 PM

Yes the crossmember needed cutting.. nothing major. I'm using two RH manifolds as you can see in the pics above... the one on the pass. side is from a '69 GTO and the driver side is from my manifold collection (I'll have to check on the number).
Yes I modified the steering linkage that goes from the firewall to the steering gear box. I'll post pics soon... I've done tons of work on it lately.

Kris.

72LemansFreak 05-06-2012 06:03 AM

Phenomenal work!

KARGUY 05-18-2012 05:21 PM

Any updates?

Very interested in this project.

Thanks

RUDOLFSSON 05-21-2012 06:16 PM

Have you finished the exhaust system ? I am interested in the pipe routing. Any other
advise to others on this project.

Hammertime Mike 06-10-2012 09:09 AM

I like the work that you've done. Pontiac motors work great in trucks. TORQUE TORQUE TORQUE !!

Stuckinda60s 06-10-2012 09:12 AM

Ya know, after all the times I've viewed this thread, it just dawned on me that you're doing this in Iceland. That impresses me even more, you don't have an easy access to parts or support.

MORE KUDOS!

RUDOLFSSON 06-11-2012 05:28 AM

Thanks guys! No exhaust work yet.... working on trans and rear as is.

RUDOLFSSON 07-09-2012 08:11 PM

Shorty 12 bolt truck style rear. 3.08:1 gears, passenger 12 bolt 3 series Eaton Posi (had to machine minor clearance to make it fit), big Ford bearing style ends (cut out of billet), 30 spline Strange axles, BOP brakes from a 8.2 rear and lightened 7.5 S10 drums.

What a cocktail... LOL

welcome

there is another system offered by them with longer head pipes to mate to shorty headers. It may work better for you to adapt to manifolds. It's the same price as well.

http://www.summitracing.com/parts/SUM-680126/

Nice option if you don't have enough scraps.

RUDOLFSSON 07-27-2012 04:11 PM

Fired it up for the first time today.... Will post pics of the exhaust later. I installed a factory exhaust (almost direct fit) from a 2004 LQ4 Hummer and connected it to the pontiac manifolds with mandrel bent pipes.

Stuckinda60s 07-27-2012 07:11 PM

That's just too cool!

A little (Unsolicited, I know) advice. Sell the Holley and get a Quadrajet for it. Preferably one done up by someone like Cliff Ruggles.

You'll probably end up with more power and you'll definitely enjoy better mileage.

Pontiacmuscle 07-27-2012 08:36 PM

VERY Nicely done!!! Looking forward to seeing more...maybe a video?? DROOL!

Yes a q-jet would be better no question about that... I just have the holley on it for now, will do the change later when the car is all finished up.

Donovan 07-28-2012 05:50 PM

bad ass

Well done with the hummer exhaust, love it!

RUDOLFSSON 08-13-2012 02:40 PM

Man I need to put up some fresh pics.. It's almost complete, just put it on 4 corner weights and looks like it will weight 2900lbs w/o driver!! That's nice considering all the heavy street parts that are on it ( 18" wheels, all steel, factory manifolds, factory hummer exhaust etc).
I'm putting a service replacement SD '74 Q-jet on it with electric choke, fresh rebuild kit and new primary rods from Cliff... I'm excited to test it out with the new carb :)

Stuckinda60s 08-13-2012 03:42 PM

It sounds like a great ride! Potentially good mileage coupled with respectable power.

Overkillphil 08-14-2012 07:46 AM

The Hedman shorty Pontiac headers may be justified in this case once your ready to dump the logs. Very nicely executed project!

what did the weight look like on each corner?

paul s. 08-14-2012 04:18 PM

VERY NICE WORK!

RUDOLFSSON 08-15-2012 04:05 AM

It was like 59% front.. and pretty equal +/- 20 pounds between sides. I didn't write the info down since it's not 100% done yet. It's got the battery in the front and heavy stuff up front so that explains the front % numbers. But hey it's a street car! A car like this gutted out with e-headed motor and glide should be 2500lbs easy.

rohrt 08-15-2012 09:13 AM

Love it!

What are the rims?

RUDOLFSSON 08-15-2012 10:21 AM

18" E/T classic five. 18x8 up front and 18x9.5 out back. Nitto tires, the back are drag radials.

RUDOLFSSON 08-17-2012 05:06 PM

Fresh pics as promised :)

Nice looking!!! Got any pictures of completed undercarriage and exhaust?
I am looking to duplicate this project also. Great job!!!

Thanks,
Karguy

Donovan 08-19-2012 08:11 PM

still 60 pounds lighter than my RX7 with an LS3 in it :) very cool

RUDOLFSSON 08-20-2012 11:41 AM

Will take some pics of it next time I have it on the 2 post lift.

Thanks :)

Stuckinda60s 08-20-2012 12:31 PM

I really like that it's so clean and understated. Anyone who takes a good look at it can't help but be impressed with your detail work.

RUDOLFSSON 08-22-2012 05:54 AM

Roll pan I made the other day...

RUDOLFSSON 08-25-2012 05:18 PM

Here's some fresh pic of the quadrajet I finished today and pics of the exhaust work someone wanted... Man it runs tons better with the Q-jet... need to get it out on the road now!
