You will find the manifold here; http://www.appliedgmc.com/level.itml/icOid/481 It is $600 and Gary Rockwell designed and casts the manifolds. I think Jim at...
Ouch, that hurts. Hay, HAY!! Look what I found! It's EXACTLY what I'm looking for. http://www.summitracing.com/parts/PFS-57026/?image=large Have the machinist...
I'm surprised at the price for the Howell TBI from Applied GMC. If you buy the TBI setup for the GMC direct from Howell, it is around 1200 bucks. I wonder what...
Excellent points there. I appreciate you sharing what you know. For these reasons, we settled on a ratio between 8.5:1 and 8.75:1. I've been thinking... If...
You stated to go with the cheaper 454 EFI, do you mean TBI? In other words, trying to figure out the difference in value from TBI to multiport? BTY: If you are...
Generally speaking, the 454 stuff is cheaper then the 455. Since I'm playing with the numbers anyway, I could pick up a multiport (or TBI for that matter) for...
I would recommend calling Howell Engine Development and requesting their printed catalog. It has a bunch more parts listed than what is on line. Originally...

Thomas: Either the engine has lost power/efficiency or something is dragging. Easy Test: Jack up each tire and spin the wheel. Harder Test: Check the...
Thom, Don't know if I'd ever be considered a gear-head, LOL, just broke. I piled in nearly $65k in my coach in the past 18 mos. Everything is basically new...
Maybe I'm just picky but the location of my tandoms in the wheewells in making me a little crazy. The right set is @2" from the rear and @4.5" from the front...
I know Tom (aircraft electrician) installed TBI in his coach and was getting a solid 11 mpg, but that was not towing. I've also heard fairly good things about...
Thanks Marcus, I haven't check that accurately. Will do ASAP. May head me in the right direction. You goin' to be able to meet us at Quartsite? Stan...
Its hard to say what is really wrong. One problem is that Revcon sold off all the uprights when they went bankrupt in '86. This may mean that things were not...
I would be more interested in the distance from the center of the front wheels to the center of the rear wheels. Hook a tape measure to the front of the rim...
I don't have much experience with the Revcon, yet. But.... Checking the air in the tires (the tow vehicle) is a good idea. I flat towed an offroad rig for...
That is funny. I have the squirt gun set up on my 73 also. it got disconnected somewhere. My 73 250 runs 10-11 mpg real consistently, and i climb lots of hills...
Stan, I keep the tire pressure up in the toad so that can't be it, but thanx for the tip! We'll get this figured out, darn it. We 2 are planning on being at...
I feel the need to move the fuel filter from between the axels to a more accessable place. I have thought of running the fuel lines up beside the tank filler...
Marcus, I checked the tandom wheel spacing and they are almost the same 1/16" difference. The measurement is 36" between wheels center to center. I talked to...
