Re: 72 GMC Short Step Build
Hey Z10,
You're going to have to turn loose of some of your Cialis brochures. We need water pump gaskets. |

Re: 72 GMC Short Step Build
What purpose does the MLV accomplish besides not laying down very well? I never seen the stuff used here before so wondering if its insulation or sound property's?? Thanks!

Re: 72 GMC Short Step Build
Diceman, can you respond to this comment from "Airstream" from a TPI post I'm monitoring?
Quote:hey z10, I see you are building a surge tank. I was going to make a fuel injection cleaning tank that i was going to fill with cleaner fluid and pressurize it with air and feed it to injectors. My tank size and style was a lot like your surge tank. I discussed this with my brother ( a mechanical engineer) and he said "you must have domed ends, they look like bell ends. If not and the ends are sharp 90 degree transitions, these areas are stress risers, create flexing, and eventually crack". This would lead to pressurized fuel spray in a hot engine compartment with spark generators (coils, alternator, etc). My brother also said to look at any ASME (american society of mechanical engineers) tank and you will notice rounded ends. I work at a power plant with compressed air everywhere with surge tanks, etc, etc, and all holding tanks have rounded ends with an ASME id tag listing working pressure, burst pressure etc. I think the quality of your work looks great as i don't wont to rain on anyones parade, but when i switched careers from dealer mechanic to power plant work it was an eye opener. Keep up the good work, good luck Brian F.[/QUOTE] Airstream, please go over to my build and copy and paste your comment. http://67-72chevytrucks.com/vboard/s...=1#post6356218 My surge tank was created by diceman50, I'm sure he'll respond. The tank was actually created by utilizing two DOT calibration gas cylinders which were originally rated at 500psi. As far as the domed ends, I'll default to your brother. On second thought I'll copy and paste your comment, just monitor it for his reply.

However, the point is mute since in our application there is ZERO pressure on the surge tank. We are using the mechanical pump on the engine to fill the surge tank with a return line to the main tank. The high pressure pump is inside the surge tank. It pumps fuel to the fuel rails after which excess fuel is returned to the pressure regulator which is mounted on the outside of the tank. Therefore no pressure is introduced to the tank. The pressure testing I did was for the fittings. Last edited by diceman50; 12-04-2013 at 11:01 AM. |

The jury is still out as to how well this will work. I still haven't done anything with the doors and will need to do that after we get the truck back on it's feet.

So i'm guessing this stuff may be better than just using 2 layers Dynomat first then the closed cell? Or possibly the way you layer it makes a difference? I'll be interested to read your thoughts on how well it performs, my truck is LOUD... I was also wondering if you had a heat gun if it would help shape the MLV a little? Then i had one thought, how thick are the 3 layers and will it affect the accelerator pedal movement enough to be a problem? Just thinking ahead.

As for thickness, all 3 layers are less than 1/2 inch, probably closer to 3/8. If I find it's to thick around the gas pedal, I'll just cut it out. I did try a heat gun, but the MLV didn't seem to want to hold it's shape when it cooled. The good news, is that if you trim it in smaller pieces, it stays put. My mistake at first was trying to use two large pieces to cover the floor and firewall.

Re: 72 GMC Short Step Build
First Engine Test Fit
Had some fun today. The decision was made to test fit the engine and trans. We found that the 700r4 trans and factory crossmember will match up to existing holes in the frame with out any need to drill holes. The engine stands were sorted out and bolted to existing holes, with the exception of the bottom stand holes, which we'll drill when we pull the engine back out. No interference between the firewall and distributor and the distributor will drop in. Looks like the drive shaft will need to be shortened about 3 inches. No clearance problems with the Sanderson CC11 headers. All in all a very good day. So, here's a few pics. You'll notice the engine still has the stock ZZ4 carb manifold. The TPI set up will go on later. ![]() ![]() ![]() ![]() ![]() ![]()

Time to show off "Hank"
I think it's time to show off Car Boss's "Hank". Turns out it's a pretty good tow vehicle. Photos shows Hank pulling my truck to the shop for the build. I'll bet if someone asks him he'll tell you all about this special truck. ![]()

Re: 72 GMC Short Step Build
F.I.R.S.T TPI Manifold and ZZ4 Head Mismatch
We ran into a bit of a mismatch with the F.I.R.S.T TPI intake manifold and the aluminum heads on the ZZ4. The ZZ4 heads have a protrusion that interferes with the intake seating properly. Car Boss and I have another friend who owns a machine shop, He machined enough off for the intake to fit properly. So, for those of you contemplating using this intake on a ZZ4, be aware that you'll need to make this modification. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]()

Re: 72 GMC Short Step Build
Cool Beans award on making the clamps !!!!!!! Subtle & clean.
and photo four: notched-to-fit channel makes a good (great) simple way to hold up one of the big Whitney punches to keep it from tipping over & smashing fingers & / or toes. I'll never do that again, after seeing this idea. |
