MSD 8.5 spark plug wires
Things I still need -

Sounds like a good solid combo and your car is beautiful. Not sure how you plan to wire it, but I used the how to guide on lt1swap.com...gives you all the pinouts and color codes to make a stock harness into a standalone system.
Thanks, i do plan on just modifying my stock LS1 F-Body harness i just hope i have enough slack to mount the CPU under my dash behind my fire wall some where out of sight and wrap it in a nice woven wire loom for show

You should be close with that setup....if I were you I'd clay the heads to check your piston to valve clearance and then mill the heads down to bump your compression up a little while not taking too much off to where you run your ptv clearance too tight....also I like the .040" mls gaskets to keep the quench nice and tight.
If you know what your doing you can also go in and do some porting on the heads to get them flowing better.

Fwiw, I mounted my ECU in the area were the dash speaker was above the vent controls. I ran the harness through the tunnel just behind the firewall and it all worked out fine. Nice car BTW! I plan to RR and AutoX mine, I went with a Fluid Damper 10% UD pulley.

Cool so i think i should have enough slack to mount it somewhere under my dash, How did you like the 10% UD pully im still debating on getting one not sure if a 10% or 25% was it an easy upgrade can i just do it later or should i do it all at once?

your 243 heads are good but i'd send them in for a stage 1 or stage 2 valve porting job. ls2 timing chain (50% better than ls1). imo i'd go with an ls1 tech sponsor stall over tci. just my one cent.
I bought the car in 2010 and drove it around for 2 months before blowing it apart, last time i worked on it was late 2011 and ive worked on a few swaps since so now i have the knowledge to finish it. I will post pics soon
Unfortunately i had all those parts installed yrs ago and now i just want keep moving forward and get it on the road, the heads where resurfaced and had a multi angel valve job, its just going to be a good cruiser i can beat on from time to time.
