Wow - what stall converter do you have - looks like your power is up there in the rpms! Vroom Vroom! :thumbs up:
Don't get over optimistic about that graph. Reasons; look at the peak torque, it's at 4500 rpm. You picked a set of parameters that included a long cam timing. If the car is for drag only, fine but for the street it would be much to aggressive unless you are going to run 4.10 gears and cruise at over 3000 rpm. I'm just trying to get you to see the technical/practical side of things and not just look at the numbers.
Yours is more in line with a 351 as expected but not for a 302. I am in the process of gathering engine parts for a 358 4 barrel alky engine using a sportsman block, N351 heads and a 800 cfm carb. The engine will be used in a sprint car turning as high as 7800 rpm and will still only make about 525 hp that's according to others who have built and real dynoed this combo. Point is you have to turn rpm to move air and make power from any engine. The dyno programs are nice to learn on but take about 15% off the figures because the program doesn't have enough parts spec-ed out to get really close for a $45 program. Takes one in the $300 range to get finely detailed expectation of what you will get for power.
I've found that desktop dyno is pretty close, at least in the case of our sprint. I ran the combo through, and it showed 838 HP, and on the engine dyno it dyno'd 854. 410 inch bowtie of course...but one of these days we're going to build a Ford. Wonder if Outlaws will allow canted-vavle heads??? I think 850 is possible with a 410w, don't you? might stay together longer than the chevys too
That's actually about what my girlfriend's car came up with on a 5.0L mustang on desktop dyno2000. DD said 480 hp, ended up being 280 rwhp SAE. Not bad for a 302....
