Phishincruisin gets a vortec

[phishincruisin]

I started working on the crossover pipes and it is a PITA. Hopefully tomorrow morning I can get a good jump on it.
I made the signal conditioner for me tach signal. It wasn't too hard, and buying parts through the EE department at school made it only cost about $5. I'm pretty happy with how it came out, but I haven't had a chance to test it since I don't want to wake the neighbors. Here are a few pictures of the signal conditioner.

What is the pita about building the head tubes?

What is the pita about building the head tubes?

Its been a PITA routing it so that I have clearance with my front drive line. I'm wrapping the passenger side around the front of the oil sump and over to the drivers side. There wasn't really enough room to do anything else, and I might have to extend my bump stops 1/2 in or so. I'll just have to be careful with it until it gets 80 axles under it, since I'll be moving the front axles forward a couple inches. Probably would have been easier if I wasn't using 2.5 in tube too...

That's good info since I was looking at 2.5"from the headers to the y-pipe too. Do you think dropping down to 2.25" would give you more clearance?

Dropping down to 2.25" would only give you an extra 1/8" on each side of the tube, and I don't think that will make that much of a difference. If I was to start over and do it again, I'd still use the 2.5", but I would design my transmission crossmember differently so I could run the passenger side along the inside of the frame until the back of transfer case.

so for a photo essay assignment i had to do for photo class the subject was karl's exhaust. thought id put it on here for s***s and giggles.

 

[Landcruisin'60]

Nice, that looks sweet.

 

[phishincruisin]

finally got the exhaust built. I'm pretty excited about how well it turned out. I just have to put two mounts in on the crossovers and weld it up in the morning.

 

[SARCruiser]

I understand now what you meant about the clearance on your crossmember being an issue. Looks good though. Bet it'll be nice to be able to start it up without waking up the whole block now

 

[bozone802]

waking up the neighborhood is way more fun!

How are you liking those V-Band ("Marmon") clamps so far?

I've used them at work on the dyno and I used one on the World's Most Expensive Patio Heater, but haven't yet used them on a vehicle. They aren't cheap, but they sure do look like a great gasketless solution.

 

[Willman]

Looking good!

Clean tube work!

Keep it coming!

 

[bozone802]

welding the exhaust: (flux sucks)

 

[phishincruisin]

I really like the v-band clamps sp far. They work really well for building the exhaust, as they allow for tweaking of the tube since the ID is a little larger then the OD of the exhaust tube. They are really easy to put together when installing the exhaust on the truck, and its just one nut on each joint which makes it nice.
I turned my bathroom into a paint booth since it was cold out and snowing occasionally. Painted the exhaust with some VHT paint, designed for this application. The color I got was exactly the same as the Flowmaster muffler and y pipe I purchased.
Here are all the exhaust parts on my bedroom floor I'm going to just get a turn down for the outlet of the muffler for now. I'll build a tailpipe this summer.

 

[jacksfj62]

Are you planning on running cats or no?

 

[phishincruisin]

Shes alive! Took it for the maiden spin tonight and WOW! this thing is so fun. I need to have a tailpipe made as it is still pretty loud when you get on it. It sounds great at idle, but is too much most other times.
It seems as though the GM power steering pump must be a little better because the steering seems easier then before, but maybe thats just having less weight up front.

 

[rover67]

Wow, looks awesome man! Nice work on the exhaust! Also nice find on the tach signal conditioner! I banged my head against a wall for months trying to figure that one out.

 

[kling-on]

nice I like how you ran it ... the power is cool huh

 

[phishincruisin]

thanks guys. drove it around more today. I don't think this will ever get old. its great having power in this truck, its so fun! Still need to get my VSS figured out. The gear I had attached to the transfer case came loose. I need to figure out a better way to attach it.
How does the engine act differently without the vss? I'm not getting a check engine light without out, but I wonder if its running differently. I'm under the understanding that it uses vehicle speed for engine management, particularly in the fuel mixture tables.

 

[Kurtis]

The vss leans the motor out at higher speeds and will give you better fuel mileage. It'l probably give you better power anywhere in between as well. I don't think you'll hurt anything running without it but your motor should defiantly run better with it. The computer controls the timing and air fuel mixture off of the vss so its defiantly something you want to hook up eventually.
