B3000 SHO swap

Looks great! Can't wait to see more progress

So today I worked on the balance tube. I had a couple customer cars come in for work so I only had a couple of hours to dedicate to the truck. I really really wanted to keep the balance tube; the intake just looks wrong without it. Per my last post I was looking at bashing or cutting the firewall. Last night it came to me: section the balance tube.

So if you look in the very first post you can see the balance tube connects to the two plenums with two rubber couplers, and also has the ignition control computer mounted on the back side of it. I milled off the mount for the computer ( which I won't need since I'm going to be running MS3X), welded up the freeze plug on the back side. Then I sectioned out the couplers. I needed to keep at least one coupler so the intake could be joined/separated as needed, so I moved it to the middle of the balance tube. A couple hours of cutting and welding later and viola, intake fits. I think it even looks better than factory now as the balance tube is closer to the runners. It sort of flows better. looks 100x better. I have it all sand blasted, cleaned up, and gasket matched now. Tomorrow I'll be painting it.

On a side note, the turbo header flanges showed up today - about a week early. I can get a jump start on that tomorrow.

I'm digging it. I love to see something different than what's 'common'.

 

[c1skout]

nice looking build so far!

 

[stmitch]

Cool! Any idea how the weight of the SHO engine compares to the original Vulcan?

 

[pjtoledo]

the SHO is heavier, not sure how much. both are iron blocks, but the 4 cams and intake add up.

Maybe you should name the truck... Yamazdaha

Really nice work...

Lol I kind of like that. Yamahazda. It's better than what I was thinking: Shranger Thing. i'ts not good , but I didn't put a bunch of effort in to it.

By the way, turbo headers didn't show up. USPS delayed. So All I've gotten done is get the intake cleaned up and painted. New gaskets for the intake won't be in for a couple days, so I might loose bolt it together but right now it's a a waiting game. I'm also waiting on ARP flywheel and pressureplate bolts. I'm trying to track down a good quality harmonic damper bolt, but ARP doesn't offer anything in a close enough size to use. I'm also looking for underdrive pulleys so I can spin the motor to 8500rpm. I found one company that still sells them, but at $300 a set, it's probably going to wait for a bit. I'm also waiting on some intake manifold spacers. I want to bump the intake up 1/2 inch to clear the timing cover. But I need to get a gasket to the waterjet guy before he even starts that. And I need to get him to re-cut the thermostat water neck as I gave him bad dimensions on the first one.

This job would be so much easier if you knew how to weld!

Just kidding of course, I'm jealous of your skills. Nice work!

 

[Uncle Gump]

I kinda like Yamahazda better.

Yeah… I'm jealous of your welding too.

stRanger Things?

 

[pat8703]

Yeah. Both the wife and I have a love for Bob's burgers-esque name puns. That one wasn't well developed, but like I said, I didn't spend much time with it.

 

[pjtoledo]

the SHO harmonic balancer bolt is almost impossible to break. the only issue I ever heard was rounding it off because of cheap tools.
they can be really stuck on.
they are 14mm x 1.5 x 50mm. the flange is 45mm wide. head is 19mm.

 

[pat8703]

Yeah I wouldn't even consider changing it out if it weren't for the fact that the motor I picked up doesn't have one an I'm pretty sure they're unobtanium now, short of pulling one from another motor at a junkyard (which I bought the only ATX within 200 miles of me)

 

[pjtoledo]

MTX/ 3.0 and ATX/ 3.2 use the same harmonic balancer bolt.
the mighty 3.0 Vulcan has the same 14 x 1.5mm threads, but it's too short.
maybe some other engines have a similar bolt.

I'll agree that parts are getting hard to find for the Yamaha V6 SHO engines.

damn hoarders
