Hi. I was just wondering how accurate Desktop Dyno 2003 is? I built an engine and it comes up with 548 hp at 6500/ 503 ft/lb TQ at 5000, at the crank.

385 sbc
11:1 compression forged flat tops
dart Pro 1 200's aluminum 2.02/1.6
solid roller (lunati 50169) .606/.587 248/252 @ .050
vic jr single plane port matched
750 quick fuel dp
1 3/4 primary tube 3 1/2 collector headers

sounds kind of high to me. Plus I think the carb may be too small, bad hesitation when you stab it at a stand still, it cuts out.

Thanks

sounds like you need a carb, but that could be pretty close. Only one way to know for sure.

Usually its about 5% over the top.

Do you think an 850 is appropriate? Im in salt lake city, utah abt 4500 elevation

Jesus that's high! I'm at like 400ft. If you're thinking of going with a different carb a custom one would be well worth the money IMO. you're only looking at a couple hundred more and a good tuner can get that thing dialed in perfectly- which is harder than you think to do in your own garage.

Call up a couple carb shops and tell them what you have and what you want. Most of the better shops will work with you.
