You're right on all accounts. It cost a ton just in parts to get the 700r4 to tolerate some abuse, where a Th350 needs very little and be built tough for under $125 in parts including the rebuild kit. You'll spend close to $500 in parts alone for a 700r4 just to have that OD, and it's still not the strength of a Th350. You might suffer some mpg, but the cost difference pays for some of that, and you're trading for dependability for the lost of a couple to a few if you're lucky mpg. I will run a 700r4 in a OEM or a little power adders trucks, but not for my toy that I intend to give pure hell. Also, some will tell you that 700r4 is better because it has a lower first gear. True that it does. But the 700r4 also has a big gear gap in it's ratios, so what you gain in the low end you lose in the mid range anyway. That taller first gear can be gotten around with a little lower rear gear and/or higher stall and a good trans cooler. Pros and Cons to both. Boils down to what your main purpose for the vehicle is, and make your trans choice accordingly.

Did you say a lil cleanin or a lil pic??? I can tell those are auto parts but ..... I still think I'd find a hydro boost off of a 6.2 truck or a 1 ton truck before I'd go with the Astro system. I forget our purpose of this hboost discussion now wo reading the thread again, but only reason to really want a hydroboost is if you're running a biggo cam with a loss of a vacuum.

Has anyone used one of the adapter kits to mount the sbc serpentine setups on. Bbc? I'm considering one but would like some input first.

I have the Kwik Perf kit on my 454 but I have not cranked it yet. Everything about the kit fit nicely and installed very smoothly. I got the bracket casting numbers off of their website and went found them at a u-pull-it real cheap (I got the pass side bracket without an air pump).

Following their website, I got the bottom crank pulley listed by part # from GM and a water pump for a '99 model truck application.

Two things the site doesn't address is the top radiator hose and fan -

Once the kit was installed I noticed my original water neck pointed right at the alternator (top pic). I ended up using an Edelbrock water neck that pointed straight up (from Summit Racing) and a top rad hose (again) from a '99 C3500 truck.

For the fan, I got a 9 blade fan and clutch from a (you guessed it) '99 C3500. these parts fit nicely but I haven't run it yet to know if the fan clutch is a strong as my old standard rotoation HD unit.

Here's a couple of pics -
