PM me. I do not understand what you mean by the ZR1 heat exchanger assembly and don't want to clutter up Josh's build thread. I do want to get my oil and water track temps down. I thought the DeWitts would do that in addition to getting the oil up to temp (which it does fine).

Cant wait to see results. I got in contact with comp cams they said mine was infact a SR cam and that they misprinted my card based off the cam id lobes. I'm dropping off the head gaskets tomorrow then she will be underway.

Nice build. Recently finished an HR cam build with Tonys TFS heads and E85 that did 642/55X on a dynojet SAE.

That's a very impressive torque curve. That's got to be a tire burner!
How much valve lift with the cam? Which rockers did you end up going with? That's a mean mod list. I'm looking forward to getting my MSD IM back from Tony.

Your intake is coming along very well....should have it wrapped up and heading back your way next week sometime
The combination Matt was referring to was a combo I spec'ed and supplied the customer with all the components. Very similar to what you and I are working with btw.....my new MMS TFS heads, the shaft rockers I had Yella Terra build specifically for my new heads, a ported MSD intake, and the cam was a custom I helped him with also and it was only 247 @ .050 on the intake (big but not ridiculous)....had a 261 exhaust lobe on a 114 LSA which helped tame the cam some. The car drove extremely well for what I would consider a more aggressive combination.....Matt did a nice job with the tune getting 6th gear to run pretty smooth even as low as 1300-1400 RPM's.
Note that the more efficient cylinder head design had a hand in that also however. Getting 412-414 CFM thru an intake port that's 5 cc's smaller than stock means you have a tremendous amount of airspeed in the runners and that really helps negate the negative aspects of reversion with larger camshafts. It's much more difficult to change the direction of a faster moving column of air then a slower moving column of air....just another perk to factor in when your weighing which cylinder heads to purchase. While I can do a really nice job with stock castings, clearly the best results happen with my much more efficient (and more effective) clean sheet design. The best cylinder heads I have designed over the years always had a alot of air across the lift curve (not just big peak numbers) and modest cross sections which really improves the airspeed in the head. Moving alot of air at higher speeds always better packs the cylinder and really helps improve the lower and middle part of the torque and power curve as well. It really improves the volumetric efficiency of the engine a great deal and you can see that with very high BSFC numbers on the engine dyno as well (for the guys that have the opportunity to test on them).
Here is the thread documenting the 642 RWHP build (on a dyno that doesnt give away the numbers!)....customer was thrilled with the results. I actually had the opportunity to drive that car.....it's quite impressive and I have driven alot of fast cars in my day (there is a short in car video in that thread with me taking it for a quick blast!).

Thanks for the update Tony. I can't wait to get it back together and tuned. I'll report back with dyno results from the same dyno, some pictures, some video, and my description of how it drives. I just watched the short drive video clip, it just EXPLODES acceleration after each gear change, zero hesitation. Credit no doubt to your port work.

Maybe I missed it Josh, but who is going to be tuning your car?

Mike Carnahan from Vengeance Racing. He tuned it for the previous combo, and I have an autocal with integrated Innovative wideband setup so he can remotely tune my car via email. I'm very satisfied with his tuning.

WCCH Heads
In case anyone is interested in my WCCH Stage 2 heads with Ti/Mo intake valves/PSI springs, I listed them for sale in the C6 Parts section.
