I'm doing this same swap right now, I'm in upstate SC!
It looks like the trans cooler has 1/4 nps threads. Does that sound right?
Yep. Summit carries the fittings (sold as a pair) for about 20$. But, FYI on my swap with the STS mounts I have zero room in the tunnel for anything but the aluminum Camaro lines. Id recommend using the stock cooler lines and swage a -6 fitting on once you're past the crank pulley.
As Sts suggested I'm making spacers for the trans mount and I think with his and virtuosity's help I have 2 solutions for the colUmn. That should shore up the figment issues.
I am moving on to planning the fuel system and the trams cooling lines. Here is what I think I know about the fuel system:
Low pressure pump in the tank sends fuel to the high pressure pump under the drivers side through flexible fuel hose.
High pressure pump supplys 43 or so pounds of pressure to the Bosch jettronic rails. I assume these are high pressure hoses but I forgot to look today.
I think I can keep the in tank pump and replace the hoses from the tank to the high pressure location. Then use a 60 pound pump with new style fuel lines to the ls fuel system. Then return the fuel to the pickup with new hose.
Does this theory hold water?
As for the trans cooling. I don't know how I'm going to get hard lines in there. The fit is very tight. Are there flexible trans lines?
Use the Corvette regulator/filter. And buy the Dorman tool for nylon line, you will save alot of money vs. -AN or FI hose. The nylon is < 50 cents a foot, and you get factory style quick disconnect fittings.
You also wont have to buy an external regulator or anything ridiculous and keep the clean 1 line for 75% of the run.
I welded quick disconnects onto my in-tank sending unit as well.
Pump, if you're on gas a standard 255 will work.
On your rack clearance, I had the same problem with this kit, but I didn't forget to keep the aluminum cross member spacers. I can fit a folded piece of card stock in between the rack and pan i.e. they don't touch but they're VERY close.
What sort of space do you have now?
