Try using a coffee can with a hole poked in it to let the coffee out, then make yourself an adapter where you can solder the hole in the coffee can with a washer with a small hole in it and just on the lid, solder a 1/8" tube through it and run the vacuum from your engine to a tee type vacuum check valve mounted close to the can, and the other end of the tee to your heater/AC controls.
That way, your vacuum sucks on the can, the vacuum goes to the heater controls, and the check valve keeps the vacuum in the can from escaping back into your engine when it is shut off.
The can acts like a vacuum reservoir.
Is it possible you got a vacuum reservoir with the donor car? check it out.

I sure I can find a vac reservoir and the pick a part. Another suggestion was that I should get a old heater (petcock) valve and install it on the heater hose from the engine to the unit.

Thoughts?

Nice work on your TPI. Here is a pic that I took of mine when it was just getting running. Found a complete TPI from an 89 Z on eBay. Added fuel sump, hoses and a lot of hand wiring to put the ECU and relays in the cab.
As to the AC and temp issues, what connections do you have from the ECU to the AC?

[oossuuu754]

We rewired the complete truck with a new TPI harness from Larrys Electric. Although I wouldn't recommend them, since they sent me a 6cly Memcal labeled as a 8cly 350 Memcal that cost me weeks and hundreds to get diagnosed as the culprit to my piss poor engine performance.

cool hoses where did you get them? im doing a ramjet in my 59 having a hard time finding upper hose

Yet again, I forgot about this thread that I started.

My truck has been complete for a year now. However, I didn't take the final photos of the engine compartment until yesterday. So this was timely that it came back to the top just now.

I just recently added a Billet Specialties radiator cap. Nice product. Sure beats the cheap one with Chinese writing on that came with the American Eagle radiator.

I ended up redoing the radiator fans. I went to dual HP Spal 11" fans because I had issues with the engine running warmer than I liked with the low profile 16" fan I had on originally. Solved the issue completely.

this is how i routed around the air filter on my ramjet into a stock radiator: short rubber couple into 90* stainless tube into rubber 45*

[roger55]

Best way to do it Ogre.
I did the same thing with my truck and my Belair w/Ramjet I showed a photo of earlier in this thread.

I do not like those bendable corrugated metal hoses. I don't care for the way they look and have heard they can crack.

Cool Thanks! Where would i find a 90 out of stainless?

hey roger55, do you have issues with water drenched air filter when you drive in the rain? did you do anything on the inlet to your air box/filter inside the fender to eliminate that possible issue?

We've put over 900 miles on the truck since complete but it hasn't been driven in the rain. Even though the air inlet on the cannister is outboard of the path of a tire splash trail, I intend to make a guard on the inlet to make 100% sure water can't splash in there. But I haven't gotten around to it yet.

I don't think we will drive it in the rain, but I do want the truck to be ready for an unexpected rain when we are out somewhere.

Wow, very nice. Do you by chance have a photo of the new fans?

[tmoble]

or you could have a radiator shop move the outlet over to the drivers side. minor deal for any good shop. have a radiator hose with a 45 bend.

What's the deal with the 2 overflow hoses on cap neck? I don't recall ever seeing that before. Are you running a real surge tank?

looks like a good bagger setup. are those shock towers off a chevy pickup?

is there a valve cover adapter/spacer on the drivers side too? That's a nice engine. 430HP vortec?

[tmoble]

full of questions, aren't I?

What about the those upper a-arms? are the adjustable for length like a turnbuckle? or do you have to unbolt them to align the front end?

[Coupeguy2001]

T Mobile, that's the reflection in the radiator on the overflow hose.......

Lol yeah click on my build link from day 1

I'll look up your build thread, thanks.
