Would someone please run this on a Desk Top Dyno???

[billlsbird]

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???

THANK YOU Bill, aka billlsbird.....
