Scott, congrats on getting your car running. What changes did you make to the motor?

Come on down Chuck - I'm sure we can find a trailer to get you back home.

Default New improved #414

Thanks Mike - I've been having withdrawls as i sent the engine week before Christmas so haven't had any drive time till the last few days!

I sent the engine to Keith Craft, and he basically rebuilt it with the following new items:
- Diamond pistons
- Stage II port and polish the heads
- Drilled block for hydraulic roller cam
- Install Comp Cams cam with intake duration of 242 and lift of .645, exhaust 248 and .635 lift (old Isky was 250 duration and .525 lift)
- Smith brothers push rods
- Polished crank, balanced
- Dyno test

Net is 566 HP at 5900 rpm, and 584 torque at 4600 rpm - about a 150 HP increase!

Also got the new TKO 600 road race tranny installed.

Installed a competition style dash with Smith's gauges.

All I'm waiting on now is a new braided steel oil pressure line, and for Nisonger to replace the speedo which had a problem.

Had a near disaster when the nylon line contacted the headers, melted through, and sprayed oil on the hot headers. Had an oil fire on the headers but got it out and after clean-up I have some paint repair to do on the bottom edge of the header opening, and a couple of wires to replace.

Talk about freakin' out - second drive in the car and I'm suddenly enveloped in a huge cloud of smoke. Luckily when I pulled over a trucker saw me and came running with his fire extinguisher (note to self - ALWAYS re-install the fire extinguisher before going on a test drive - duhhhh)

And - I just got the kitchen pass to go to Year One and Mitty!!!!

Now off to do the non-rain dance

Assuming that my shopworn Cobra credentials are still valid, I'm ready for some playtime. Over the Winter the old 'Vette has been working out on the Bowflex, and has packed on an additional 300 or so horsepower (no nitrous oxide involved BTW).

Another thought for an outing: as you guys know, the SAAC convention (6/30 -7/02) is at VIR this year, and some of my old Cobra buds from NJ are going. How about a group ride to that event?

Rob:

Not to question the old professor, but I'm pretty sure that the Mitty is at the end of this month rather than May.
