I don't know if it's the 1 goofy head thats on it or the cam. Hopefully we get some real dyno time at the end of the year to swap some parts and figure it out.

Something sounds off.........it should be making maximum power right around 6800 rpm.What rpm does it drop to on shifts.

5800-6000 Also Glenn in my previous post I meant to say drops to 5800 and won't move.

Clutch slipping?

Absolutely not. Just dead, no power.

I don't think so, same cam as it had before and this wasn't a problem before the engine explosions.

It looks like me I would get another opinion on the clutch just to cover bases . Call Rob Youngblood 208 880 6214 won't hurt

Todd your pm's are full. I agree with Don give Rob a call.

Something doesn't seem quite right if the car goes 6900 at 117.50. That's fast enough to indicate that the engine makes a reasonable amount of horsepower.You said that it has 5.14 gears and goes 6900. That almost seems to me that the car needs more gear. My 327 Chevelle in I/SA had 5.57's in it when I ran it at Pomona a few years ago, and it has a Glide with a typical stocker converter. It ran 7480 in the lights, and it felt like it wouldn't go any faster, it was pretty well done. That figures out to 68 RPM per MPH. I put 5.38's in it, doesn't sound like a huge change, but that is 61 RPM per MPH. The engine seems to like it better, although the first half of the track is about .03 slower. The overall result is about the same. Your engine seems to pull fourth gear OK, but a little more gear would make its job a bit easier. You have a car there that is consistent, and a consistent set of results run to run. Maybe moving the cam up might show some results. I don't think I would change too many pieces until I had some answers. The clutch would be one thing to investigate, how ever.

It's not a clutch issue, I've had it loose and tight and it still has issues pulling early in high gear.
