nurkvinny Posted January 15, 2005 Report Share Posted January 15, 2005 I wondered if anyone has dyno software that estimates hp numbers. Or, if anyone could guess the hp for the following set-up: sb Chevy 383 Dart heads, 2.02 valves ~11.2 to 1 roller cam, ~300 duration, 550 lift high-rise, single plenum intake + 1" spacer 750cfm Holley lighter-than-stock rods and valvetrain large tube, open headers fully balanced oil windage tray lightened flexplate no mechanical fuel pump no mechanical fan full MSD ignition with a 100 shot. Also, looking for a guess of 1/4 mile times / trap speed in a good-hooking vehicle, running a high stahl, corrected gear ratio of ~4.11, and weighing ~3000lbs. Thanks.

Dave1647545494 Posted January 16, 2005 Report Share Posted January 16, 2005 10's 120-130mph thats just a top of the head guess though Quote Link to comment Share on other sites More sharing options...
Tinman Posted January 16, 2005 Report Share Posted January 16, 2005 You will need to know the intake runner size of your heads to get even a ballpark figure. Everything else sounds good. Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted January 16, 2005 Author Report Share Posted January 16, 2005 200cc, and you should know a little something about this particular engine's history. It ran pretty well, but we had some parts sitting around that I decided needed a new home. Quote Link to comment Share on other sites More sharing options...
Tinman Posted January 16, 2005 Report Share Posted January 16, 2005 Ahh, I see. That motor, with your extras, in a 3000lb. vehicle is going to be quite the package. Quote Link to comment Share on other sites More sharing options...
desperado Posted January 17, 2005 Report Share Posted January 17, 2005 Here's some numbers that my software spit out according to your specs http://www.foornet.net/images/383dyno.jpg Quote Link to comment Share on other sites More sharing options...

nurkvinny Posted January 19, 2005 Author Report Share Posted January 19, 2005 Keith, can you run that again with 2.05 heads, 64cc chambers, several degrees of advance, with an 850 carb, solid cam? Quote Link to comment Share on other sites More sharing options...
desperado Posted January 21, 2005 Report Share Posted January 21, 2005 OK, I ran the numbers as you requested, these are TOTAL CC in the quench area, not 64CC heads, you have to remreber that true CC is the head CC, figuring with the dome displacement, and the CC of the head gasket. Its' best to go with Compression ratio that your heads and pistons are going to generate. It's a way better number to work with. Also, I have no way of doing ignition timeing, only cam timing, I ran it up 4 degrees, but you might want that pulled back. So let me know. Here it is without the 100 shot. http://www.foornet.net/images/na.jpg Here it is with the 100 shot http://www.foornet.net/images/sprayed.jpg Just for grins, this is what I am putting together for the truck, I need only to buy the cam and lifters. That and some extrainous bullshit, gaskets, head and main studs and assembly crap. http://www.foornet.net/images/sprayed357.jpg Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted January 21, 2005 Author Report Share Posted January 21, 2005 That makes me REALLY wish I went for the 2.05s. Quote Link to comment Share on other sites More sharing options...
