I have been building this 68 Camaro for over 2yrs Pro touring style but more curiser and hit the autocross and roadcorss maybe 2-3times yr and im at the point where i decided to upgrade my LS1 why not rite!

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.

On my GTO with the stock harness I had enough wire without cutting to move it from under the hope to up behind the gauges in the dash

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?

That should work....concentrate work around the valve guide, take out the flashing, then blend everything as best you can

Glad to see your back on the project. Progress pics are alway enjoyed so let's see them. If you only knew how long my 68 has been down you'd feel good about yourself for sure.

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.

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.

Nice!! Where did you get the blocking plate for the two outlet ports at the waterpump? These ports go to the inside radiator

Joey, there is no blocking plate on the water pump for the heater core. I see two open holes.

I actually tapped and threaded the ports on the stock pump, I will end up using stainless steel plugs
