Don_F, thanks for your input. I have looked at the TBIchips website. I believe they got 25 rear wheel HP on a c/k tbi truck just by cutting out the OE y and replacing with an aftermarket. I wasn't sure if the same applied to the g-van tbi y-pipe. Luckily I don't have any major hills on the interstates near me. The worst interstate hills I go on are on I44 between St. Louis and Joplin Mo. in the ozarks. My 94 GMC C1500 gets down into 2nd gear(4L60E trans) on a couple of them at 50 mph and barely holds 3rd gear on several others pulling my trailer with car on it. That is with a completely stock TBI 350 putting out a whopping 190hp. I do realize the motorhome has the aerodynamics of a brick and weighs at least a ton more than my pickup. I picked up a set of either brand new or freshly re-manned vortec 906 casting heads while I was at the junkyard(they haven't been fired yet, junkyard score of the year). I was debating whether I wanted to put those on the motorhome or on my pickup. I already have an edelbrock performer rpm intake for them. That may not be the best suited intake for either one I know so if its a dud, let me know and I can probably trade it for a regular performer intake. It sounds like the vortec heads would be better off on the motorhome, I should look for another set and put them on both.

Hey guys!
This thread was a great help to me, I ended up going the route of the Hedman headers, shorty plugs, and paint for my G30 Ambulance project.
I noticed a performance increase (judging from the seat of my pants lol).
My favorite part is the sound, Nothing beats a big block withe headers!
Anyway, I filmed the whole thing so if links work here (sorry I am new) you can see how I did it.
Its a 3 part video, I posted the last part here because its the most interesting but the others are out there if you need them
Hope someone finds this helpful!
