This was with the free Engine analyzer 3.0 by performance trends.
I was screwing around just looking at differant cams with a similar setup as mine. The program does not have 4v cleveland heads, so these are #s off of 2v heads with 2.16 and 1.65 valves. 10.5:1 Compresion. Ok question is this:
I ran 3 cams. all three were recomended, and ofcourse, I chose the "Best" one. The Choices were:
280H .53"I .53"E 230 I 230 E
305H .585"I .585"E 253 I 253 E
32-638-5 (solid) .564"I .589"E 246 I 256 E
Now, I always heard the Solid will make MORE POWER...everywhere. And will rev higher, then the hydraulic. Well I did 12 total dyno runs, with 16 differant categories. This is a synopsis of the results.
2000-6500 RPMs with 500 RPM Increments.
(SOLID)
TQ 416 @5500 Avg 323

I only wrote all that out so you guys can see with me what I am seeing. What I am seeing is the Solid wins the most categories. Of the 16 Categories, the solid wins in 10 of them. 305H 5 280H 1.
What I am wondering is is that what the solid cam is supposed to do (make more power pretty much everywhere, but not as high RPM?) or am I mislead? The only place where the solid got beat up by the 305H is 5800-6700 RPMs with 100 incriments. Other then that the 305H made more HP EVERY TIME except the 5800-6700 100RPM inc.
What is the deal though, was I wrong in my thoughts??
Thanks for clearing that up...Does this seem accurate? I had a Desk Top Dyno run my motor at 515 HP @6500, and 455 Foot lbs. I imagine that is with 4v heads as well?
