Who's got a desk top dyno?
 

Now that I have all the major pieces bought, can you plug it in and see what it says,, or anybody have any good guestimates?

454 8.5 compression, 731 cam, promaxx 320's, ( Intake .200 = 155cfm, .300 = 228, .400 = 289, .500 = 336, .600 = 368, .700 = 388 .800 = 392 exh .200 = 117, .300 = 158, .400 = 205, .500 = 228, .600 = 258 (w pipe 277) .700 = 260, (280) .800 = 261 (283)... 1050 dom on a 177 blower, 5psi.

No desktop dyno, but I would guesstimate around 580hp @5400 rpms.

put it together bring it up to michigan, 30 min north of detroit this time of the year my "real" dyno is looking for jobs to run

567.3

I modeled a 525 SC then changed the heads to your flow numbers, swapped cams and raised the compression. It shows 617 HP.

Oh boy.... I think Im going to need a bigger prop.... :party-smiley-004:

and that thing just before the prop.

yeah, that too... when I replaced the lower 2 years ago, the propshaft and the vertical shaft both had twisted splines

What you have in it for power now and what kind of speeds are you running ?

If I throw the little pulley on and a 2" shorty, the bam speed calculator thing predicts top speed somewhere between the mortuary and the crematorium....
