Nobody knows! We even started a pool on it, but enkei has never dynoed it. I'm sort of pulling it out of my ass, just based on seat of the pants in it and other fast cars I've been in, plus the engine combo, and I think I put my money down on 575WHP . . . when it's all working.

Ben, I know Id never get anywhere near that top speed. Haha. And ps, I love you for that estimate.

Also, keep in mind after lower and smaller tires, my c3 is 5 inches lower than stock in the front.

Basically they have to be kept much looser so they can expand at the much harsher long WOT period, otherwise they can actually melt. That's what I remember from the later cobras. Actually might been the piston heads themselves that started binding in the motor. The down side of course is that you'll have a "loose" motor for more normal driving.

I plan to gap the rings to .022 for the top ring and .018 for the second ring. I'm also going to be running Probe SRS pistons and will have the bore finish honed for a .0045 piston-to-wall clearance just like we did with the 331 we built for Eric's Mustang.

Spot on, thats what the silver engine came out to

Maybe after finishing the current projects within a generation or so, we could build a Motorgen top speed car and take it to the flats. That'd be fun.

I filed mine to 24 and 20, minimum for the second ring was 14 but they recommended alot more. Didnt feel like fucking around to make 3hp

I moved the other posts to their own thread to clean up everything. They're more at home there.

Let's change it from an estimate to a solid number. I happen to know of a dyno day in Upland at 10am on Sunday September 30th. $50 for 4 pulls there are limited slots available so don't go telling everyone and their mom. No excuses now. There might be a cobalt and a Sky red line there that will give you a run for you money on the rollers though. They are both Turbo swapped and they should get close to 500 to the ground.

If you drop an LS block in anything I have HP tuners, and I know a good tuner who will help us out. I'll donate the time and money for the tuning.
