Well, 55K swap looks to be a breeze emissions wise.
Focus for the build stands, in order:
SS Intake tube's from friend + K&N filters
Tune - Interesting data and equipment to come to life from this one hopefully

(and not what you're expecting)
Put the new OEM rim on, Plasti black and clear - Haven't cause I'm lazy
New lower passenger control arm
Alignment
Wavetrac
SPEC clutch - Which wont go on until the 55K motor goes in. I emailed SPEC asking what they have that'll hold 700 ft-lbs for a crossfire that's as daily driveable as possible... They haven't responded lol.
Then the beast of a motor... Which will more than likely see quite a lot of time, TLC and prep before going in, unlike this $250 5.0 that I said, f' it and slapped in lol.
Between collecting of parts, I'll be designing my SC cooling circuit. Also, the interior will be touched up here and there. Slowly working towards restoration on some of the ruined areas.
