Well no wonder you car seems so slow. I kid, we're still N/A.
I'm seriously going to start getting prices for a complete L67 with everything on it. Supercharger, all pullies, icm, TB, etc. I'm assuming around $450 ish depending on miles, looking for under 120k. You just need that, swap the L36 flex plate on it, and swap the engine. Then order a cannned pcm for the purpose($200?) (l67 with 3.29's) and bam I can go s/c in a days time.(or maybe I can send a pcm to a member here to just swap l67 tables in for a bit cheaper. I can do the junkyard trick, pull an airbox and pay for an airbox. Ohh what's inside? a pcm lol) Hopefully all for under a grand, I'll be happy. Of course who knows if that used motor needs gaskets, if so add $200. If I can get all quotes, I'd be up for it. Good thing I really haven't put much money into my engine, just vc gaskets and elbows. Oh but my trans....yeah it will surely die if I get a lead foot with an L67. The mechanical internals are healthy I'm sure, it's the pressure issues that would kill it. I should order a professionally remaned/upgraded valve body from tep. Welp that's over a grand now...worth it.
