	06-02-2006 03:33 AM #1Would someone please run this on a Desk Top Dyno???
 
 Hello Everyone, First I was wondering what is the best kind of desk top dyno to buy??? {for windows computer}. I want to purchase one...
 Also if someone already has one would they please run this motor threw it??? HP & TQ if possible....
 Not sure what info to give so I'll just give everything that I can think of. If any more is necessary please ask....
 
 Bottom end; 400 small block, 413 cu. in., 4.185 bore, 3.75 stroke, 5.56 rods {stock 400}, flat top pistons with 2 valve releafs. .040 gasget, 0 desk height, compression is 9.9 to 1....
 Cam; will be a Comp Cams Hydraulic Flat Tappet, EX284H, with 240/246 duration @ .50" lift, Valve lift is .507/.510, but it has 1.6 rocker arms so lift is more, 110 lobe seperation. {is the lift 540/544 with the 1.6 rockers??? not sure if I'm doing this right???}.
 Heads; are AFR, 195 Street Heads, 74 CC combustion chambers, 2.05 intake & 1.625 exhaust valves,
 Flow is;
 @ inchs, intake, exhaust
 .200, 132, 108
 .300, 198, 156
 .400, 240, 178
 .500, 260, 190
 .550, 262, 192
 .600, 262, 194
 
 Performer RPM Air Gap Manafold {dual plane}
 Carb is an 850 Dbl Pumper {I think it's to big???}
 1 5/8" headers with 3" collectors {long tube}.
 2400 to 2600 stall
 Turbo 400 trans {reverse valve body} w/ Trans brake.
 
 {This motor put out 438 HP @ 5250 & 499 TQ @ 4000 on a flywheel dyno with a smaller Crane cam. Duration was 224/234 @ .50, lift was 488 with 1.5 rockers but it had 1.6's. Guy said it needed a bigger cam. That it'd put out way more HP but probably not any less TQ}.....
 
 Oh, the Comp Cams spec sheet says that the cam I want to use has an opperating range of 2300 to 6500. Does this sound right, with what seems to me as a pretty big cam???
 
 Oh and are there any changes that anyone would recommend???
