67 Longbed GMC Patina 5.3 T56 Driver

[keetonb25]

Not a lot of picture worthy progress mainly just wiring and plumbing things correctly. But I needed some motivation so I test drove it! Just around the block but I made sure to leave rubber at every stop. No cops even showed up despite the open headers and no bed. I ended up going with the core shifter and it's great feeling, the forward to back throw with a 14" stick is only about 4 inches. Should have the truck more drivable here shortly.

That's the same thing I thought. I'm not using the straps neither. It's not going anywhere bolted in.

I actually ended up using them. Just had to straighten them out and re-bend them. Also going to have to cut the bed stringer.

ok well I guess I'll have to take you off of the strapless team. Hope it looks good for you.Truth be told I might put mine on too.

Intellitronix gauges are in.

Nice and bright. I like that you're keeping the original steering wheel (?) looks identical to mine even the rust pits on the shifter. I'll probably replace shifter it's worse than yours. Keep up the fire I like this build. And the production line markings are still on your firewall, kind of wish I didn't paint over mine already.

Yeah, even when dimmed they are bright hopefully it's not too much at night. I got a new wheel even though I like the factory one. It's just too big, and I'll be taking the shifter off since it's not being used.

Awesome build!

[keetonb25]

Got exhaust done last week, did 2.5" with MagnaFlow mufflers. Still need to build seat brackets for the buckets, and lower the front. I've been driving it though and having a blast! The steering is great with the mid 80s power steering box and LS pump. Here's a shot of the interior so far.

[keetonb25]

Well here it is somewhat complete. Lowered the front two inches, did mcgaphys front disc conversion. Put 5 lug axles in and got some wheels.

Im not usually a fan of long beds, but I LOVE the look of this truck. I think you nailed it, and with an LS swap and 6 speed, this is a truck I'd love to have!

I love the paint on this truck

[keetonb25]

Thank you! It truly motivated me too keep going getting the compliments on here.
This thing is so fun to drive, and I've been driving the $#!t out of it. The t56 makes the whole truck and the power from the 5.3 is really good too (too much for the ls1 clutch...)

Here's a cool shot from yesterday. I'll get a video driving up a killer grade here soon too.

[Big Block]

Nice truck and a great build.

[Ken B]

Awesome build! I think you nailed it on all fronts...

[kehstr]

when you say the 5.3 makes too much power for the clutch, do you mean it makes enough power it just slips?

I'm thinking that's what's going on. When going from first to second on a hard pull it's slipping. If I don't just stab the clutch to shift it works fine. But where's the fun in that?

[rustytruck50]

That looks totally killer! Nice job!!

[AnotherWs6]

Yeah, stock LS1 clutches are meh. Bone stock with 30K miles mine was slipping if driven hard. Like hitting second aggressivly. Annoying. They will live like that for a long time. Remember that GM had to safeguard the little 7.5 rear in those f-bodies. Aggressive clutch was out of the question. Master cylinders were purposely choked down to make high RPM violent shifting difficult/impossible. Fourth gens were/are good, but that 7.5 really killed what could have been a fantastic car for several reasons.

Good info there. That's what read after I smoked out the cab... but it's on the road for the summer. This winter I'll make some small changes.

[AnotherWs6]

Call up monster clutch when you're ready to swap it out. They are EXTREMELY popular for LS based vehicles. Can give you what you're looking for at a reasonable price. They are certainly the go-to one LS1tech. I've got a stage 3 from them waiting in my garage.

any ideas of what you are going to put in it? or just run it and when the time comes to change it you find out then?

[mrobvious34]

do those headers hang below the frame at all? or do they tuck up nice and tight?

[Doug's68SS]

I like the tires and wheels, what wheels are those and what size tires?

Sorry guys, haven't been on here or messed with the truck in a while. Not sure what clutch I'll go with next. The headers are pretty much flush with the bottom of the frame might hang barely below. Wheels are 20" US mags rambler. Tires I'm pretty sure are 295 60.
