New Project!

[Stover93]

Hi All. I've been lurking here on the board for a while gathering info for my 68 1/2 ton build. It's a 68 GMC cab and front clip on a 71 Chevy lwb frame, no bed. All of the metal is in really good shape. The frame has been painted and it looks like it has some new brake lines, etc. Somebody started on this truck and gave up on it.

I've never done one of these builds before though I did own a 71 Chevy lwb when I was young & cash tight. Sooo... I had a few questions.

Since my rig is sort of a franken-truck already, I was planning on cutting it down to a swb and switching to a chevy front end. Are there any issues with switching from a gmc grille to a chevy? I have a 68 Chevy grille that was in the pile of parts that came with the truck.

I pulled the diff cover and it's a "one-legger" 3.73. I'm going to switch to a posi or Eaton true track. Leaning toward the true track but I've read good and bad info on both. Thoughts?

Been talking to Silver Sport about one of their TKO 500 driveline kits. Anyone have experience with Silver Sport? They've been very responsive to my questions so that makes me feel like they'll help me out when I actually become a customer.

I need a motor as well. I'm looking at the Smeding 383's but have been considering a truck ls 5.3 as well. I had an 02 Silverado with one of those and it ran pretty dang good for a stock engine.

Anyway, any comments are appreciated and I'm really glad I ran across this board. The info here is top notch. I think I've favorited about 50 posts already!

Something like these is the direction I'm heading.

You are in a cool position to go any direction with it you choose then since you won't be ruining an original (for the purists). You can go GMC or Chevy, long or short, what ever suits your taste. Some dig GMC and some dig Chevys. Do what you want with it to suit you. 383s are cool and FI LSs are powerful and efficient. Your choice.

[Stover93]

Thanks Boog. I dig your tag line on your sig.

This rig is at a pretty good starting place. Cab corners, rockers and floor are good or have been replaced as well as the braces under the cab. It came with all of the glass, inside door panels, handles & hardware, heater box & controls, bench seat, & a bunch of other small parts. I can’t figure out why the previous owner gave up on it. It should make a nice truck. We’ll see.

My wife already named it The Money Pit.

And she don't know just how right she is.

Nice project! Mine is the color of the second one, and I really like it..

I bought my TKO 5 Speed form Silver Sport and am very satisfied with the product and extremely happy with all the support that Jack and his people offer. You can't go wrong dealing with them. Also they will offer specials often.

Thanks Wally. That's what I was looking for.

They do seem like a well run company.

I'm guessing most of you guys build your own motors. I'm not sure I have the ability to take that on. I could probably hang one together but it seems like you can buy a crate engine for about the same price as you can build one if you use similar parts.

Anyone have any experience with the Eaton True Track?

Silver Sport is running a $250 off special in the month of August (right now).

[Stover93]

I was in the local ...ahem... Ford Dealer yesterday and this Ranger was on the floor. I thought the color might look pretty good on my 68.

Not so much anymore. Crate engines are cheap enough that it makes it hard to justify the expense of building a motor, especially if you have any extensive machine work done. I built my last 5.7 Vortec but that was mostly because I really wanted to.

Welcome to the forum and I'm glad to see another GMC build. I'll answer what I can for you.

As far as converting to a Chevy grille, I believe you'll need different fenders and to modify your core support (remove the second set of headlight buckets) and there is a sort of crossmember between the fenders that might not work with a Chevy grille. It's your choice whether to stick with the GMC front end or not. I considered it lightly at one point, but the GMC's are more rare and I like them. I have always owned GMC's only so it's cool to keep that tradition running for me.

As far as SBC vs LS, I would go LS. It's definitely a question of restoration vs restomod, but LS engines are definitely more efficient and there is a huge aftermarket for them. If you already had the support systems for a SBC setup (fuel system, transmission, gauges, etc.) then a SBC would be more attractive but since you've got what appears to be a bare bones truck, you can go the LS route and get all the parts to support that powertrain.

I would recommend starting a build thread in the build subforum as well.

If you want to do a Chevy front end swap I have a Chevy rad support that I'd trade you for your gmc support as I'm currently doing a swap to a 67 gmc front end. Figure the truck has a different bed and is going on a different frame and I've always liked the 4 eyed face of a 67-72 gmc. Pm me if you're interested

Keep it a gmc, the grill looks tougher and the gmc hood letters are cool!
GMC is rarer as well

[elf w/capital T]

Wow, have fun keep us posted! I have a chevy..but i dig the gmc front too

I really appreciate all of the help and info from you guys. This site is a great resource!

[Stover93]

Decided on Omaha Orange. Got the cab set back on today. Now the work can really begin.

Looks good! That is a great color.

Went with a repop rad support. Got the new radiator installed after a week of looking for a bottom hose. And best of all l got the new motor fired for the 1st time. It was a good day in the barn!

Wow! That is a nice looking setup. You are making good progress.

Looking good so far.

I'm thinking your wife was right about the name for it (the Money Pit, because they all are)


Which radiator setup did you go with?

Sub'd.

Its the Entropy radiator. It was pricey but seems very well built. It fit well too.
