The thing I find most interesting is that none made 700 hp, which was tims original goal and seemingly easily attainable. Is it because this was wheel hp, or carb ad exhaust limitations?

I will say, this is just a computer program, I wouldn't take anything here as "gospel" so to speak, when it comes to camshaft choice.

I have a separate cam design software program, the "controlled induction" , that some engine builders utilize, and I know for sure, one of the "custom" cam sales guy is now using since it came out this year.

That program, for tims combo, suggests a 255/260 cam, for tim's engine, seeking 6000RPM max power. For 5500RPM max power, it suggests a 242/246. Pretty much EXACTLY what we saw on the dyno, with his 241/246 cam. It was about dunzo at 5500rpm.

For 25 bucks we can have the MK cam run in the cam doctor.

Not saying how it would perform, just that it could then be introduced into the equation.

The first and second column has the flywheel hp and torque, the thrid and fourth have wheel hp and torque. Just ignore the third and forth column!

Like the 290s?

Actually, the builder that dyno'd tim's engines, built a set of 540's using those 290's, with a crane "651" cam, not long before tims went on the dyno. He pulled the dyno sheet from that build, and overlayed it against Tim's. From about 3500rpm, to 6000rpm, it kicked tims combo's azz. Made 670ish hp if I recall, and better mid-upper rpm torque. Below 3500, tims actually made a little more torque, which you wouldnt think with the 290's vs the 325's.

I tried the tablet thing, I just cant get to liking them. I'm old school. I gotta have my PC. Even laptops, I hate them.

Especially when you're a dork, and sit on your computer playing with cam and engine software for hours and hours. It would take me a month to try and do what I did here, on my laptop.
