looking good, u seem to be moving pretty quick on it. when are trying to get the car done by? i bought the ebay remote coil mounts, they are cheap and look great since you are running remote coils. i currently have my car at cms getting my ds1c installed on my iroc, we will have to meet up at one of the LA meets sometime.

i used to be afraid of wiring but found out its really easy just time consuming.

i dont understand what your asking here:
"whats the length of ur cut for the shifted I still need to do mine?"

really nice work so far..i thought you woulda stripped the engine bay and then fogged it black but maby you just fogged it all first? and why the 4.8L instead of a 5.3L? just curious and i wish i had people around me here who could help me out with a project like that!!

and TPI Terror... what would it cost to do a 4th gen dash conversion? just curious.. i dont even have a 3rd gen camaro yetbut i absolutely LOVE what you did with yours...just dont know what it would cost to get it done and DONE RIGHT.. and obviously you got that covered..

umm....5.3 runs lower compression then 4.8, 5.3 has dished pistons 4.8 has flat tops. The 4.8 will respond great to that boost though....these little LM7's and 4.8's are beasts when it comes to swallowing turbo's and if you blow a bottom end? big whoop your out $350 and throw another engine in.
great build man! keep the old third gens alive love to see them at shows!
