The water/alky will still be there.
We are buying an off the shelf cooler to put after the turbos.
We are making the manifold inhouse .

I did get to talk with Bob. However he was running out the door to catch a plane. I have decided to call Crane cam and based on my build this is what they came up with.
690 Lift 262/274 @ 50 LS 114 with 1.8 rockers.
I wish I knew enough to say go ahead. Bob will be back in town early next week so I guess I should wait.
Thanks

My recommendation was on the conservative side based on your rpm limitations. I use that combo as the maximum size hydraulic roller in a 572 application and have alot of good experience with it. The cam your builder proposed is very small in my opinion, it will make a ton of torque but I don't think it will carry up the rpm range. I consider 248/252 @ .050 the smallest duration I would use for your application. The 1.8 rockers are a great recommendation. They will put extra lift on the valve and allow a less aggressive camshaft ramp profile, keep in mind they have a net effect of slightly adding duration to the camshaft. Good Luck.

for some reason i just like Radical/agressive cams and adjusting Valve lash all the time .
