The plan for my z28

i understand the rear mount for originality, but dont count on sts. do a custom set up. sts is very generic and with what they supply can usually pretty cheap in the places you dont wanna go cheap. not to mention that it is a hot turbo set up. with what you will spend after buying the sts and buying all pieces that need to be upgraded, to the front mount intercooler, you will have spent enough what you need to buy 2 sts kits just to get the most out the kit power wise and reliability wise. some have luck on their side and the sts goes together ok and make nice power but the few who do rarely get past 5 lbs of boost.

i dont see too many prochargers go more than 30,000 MI on a DD
i am sure plenty of people have had no problems. but while i was working at a chevy dealer i saw numerous chevy trucks/camaros/vettes that had prochargers installed by us and were back within 35,000MI with valve problems broken connecting rods. BUT i have never seen a totally built 454 LSX block with a procharger. lol maybe its tough enough to handle it? i agree build up a rock solid 4l60E or TH400

from the factory there isnt an ls(x) motor that is built for fi other than the ls9 and lsa. all other ls series that are factory installed are too high compression with plain cast metal materials. where as a built 454 to me for a boost set up would obviously be forged metals with lower compression with custom pistons for spray also. yea you can still install a sc or tc setup on anything but if it runs well is another story. for example a factory ls1 will not normally hold up to well past 8 psi of boost. whether it is tc or sc.

that i know but he was talking about vehicles that have hit 30k miles with sc setups that go to dealerships for work to be done on said vehicles. even though the sc setups are installed by the dealer that tmaxicana works at, he hasnt stated whether the motors were built for boost or not. so im assuming they are factory high compression motors that would be lucky to hit 30k miles with most of those miles being boosted.
