Sounds like a nice cam. Comp makes a very good product. It might be a little weak down low (under 2,500 rpms) but it'll pull like hell up high:D

a lot of times custom cams are ground by comp/crane. the builder just sends his specs to them, and they cut it.

This one has the part number machined on the end...

I just got back from Jegs an hour ago with a set of crane valve springs.. Decent price and spring rate of 330# they take a .580 lift.

the 24's are for the n/a mock-up motor

Yeah the 24's will be for n/a.. The engine will be in the car n/a for a while.. until I can afford the rest of the turbo stuff.. I was going to go with 30#ers but I think I will up it to 42's.

I just mounted the timing cover on the engine. I was going to do more work to it but I'm getting dragged to steak and shake.

Looks like I will be going with an F303 Cam unless anyone knows of a better camshaft.

I'm glad to see that you didn't get the F cam. I think the cam you got with the 114 LSA will be alot better.

What are you doing for an intercooler? I was going to run 2 87 TC intercoolers up front for my set up. 1 for each turbo and Y them together on the outlet side.

Anyway, good luck with your project. I sold most of my turbo stuff because I got cold feet... I didnt think I could pull it off. I'm lookin forward to hearing how that thing is gonna run. It should be a beast!
