Take word for it buy new water pump and cooling fans, I have good luck with the rest of the parts used so far.

Of course you will need a good tuner, I finally can start the car without it popping do to the reversed wiring, but it starts and wants to die unless I keep my foot on the gas. It stills stumbles when the car idles down at a stop signs like it wants to die it usually stays running though.

I will try to minimize hi-jacking this thread but I'm going to throw a new LS2 shortblock with AFR 205s in my 69 camaro. However, I'm wanting to put a Carb. style intake on with a 4150 style TB and a chrome air cleaner on top. Then run a real clean fuel rail on each side. Also I will hide the coil packs and put some nice Chevrolet valve covers on her. I'm looking for the sbc look without sacrificing performance. I don't see anybody doing this. Will it not fit under the hood? My tuner tunes with SD so no MAF to worry about. Any insight? Thanks first gen guys!
