Seems about right or even a little low, but you seem to squeeze more performance for a given power to weight. So I bet there's a bunch of guy's with a similar truck going way slower (mph) than you but still making similar power to weight but would calculate even less power. To me anytime I...

I get that but what proof is there that these calculators are accurate in the 1st place, the original formula was based off some guys hp estimation in the 50/60's and later Road and Track data, no actual dyno results, and when there is dyno results the calculator is assumed to be correct and...

But also why dyno's put out different results, cause the conditions of the test were different changing the power being made.

I just find it funny how a Calculated hp results are held in a higher regard than a dyno's measurement.

To me Dyno = Potential, Track = How well that potential is being used.

Rumblefish probably knows, he's done things for him, to me it seem like a hobby/business.

Depends on how well you ported the Stock Magnum heads, they could be flowing similar, so no real gain is possible. If half way in between with mild cam may not do all that much especially for the $$$$$. How much gain would you need to feel worth it?

A small port like that flowing 233 cfm must of had fairly high average velocity.

Pretty kewl, I like that, now I need one :)

My guess the owner is worried about Velocity but never heard you can also have too much velocity.

Probably make decent low end (350-392 Cid) and if it can be made to breath enough should also make ok hp, probably be expensive hp but as long the owner ain't thinking anything too crazy hp wise he'll probably be somewhat happy.

Guess that's what the customer wants, sounds like a mutt of an engine 273 heads, 340 intake, 318 block, with a stroker crank guessing probably 3.58 maybe 4 he won't say :) Sound like they want it to spin at least 6,000 rpm. He said the owner wants it to look like a stock 273, but the intake...
