Thread: Desktop Dyno?

Tweet

Hey guys I have a healthy little small block chevy here, that I know performs very well, as it consistently clicks off low 11 e.t's, and on a perfect day, and a perfect run, pull high 10's on drag radials and open headers. It's been put together for a long time, so a few of the details are probably pretty vague, but I was wondering if somebody around here could run my combo on the "desktop dyno"? it would be really appreciated.

Well anyway, my combo consists of:
a 350 4 bolt main block; bored .060 over
Manley "H Lite" forged 4340 series rods 5.7"
Eagle forged 4340 series crank (factory stroke)
Dome pistons (dont remember specific size or anything, but they are forged aluminum)
Camel Hump "492" over the counter series heads, extensively ported and polished, recut for 2.04(intake)/1.60(exhaust) vaves; I believe they flow 276 cfm (intake)/ and 198 cfm (exhaust) @ .600 lift (the heads were milled and decked to compromise a 12:1 compression ratio when matched with the dome pistons
Manley Valve Springs good for .700 lift
Crane 1.5 full roller rockers
Crane "Saturday Night Special" series Solid Flat Tappet Cam
Here is a direct copy of the cam card from Summit Racings website:

Weiand "Hi Ram" single quad tunnel ram intake; smoothed runner divider area, ported plenum and ported lower; port matched.

Hooker Hussler full length 1 3/4" headers 3" collector
and for crusing on the street I've got Flowmaster 3" super 44's dumped right out of the mufflers.

Drivetrain consists of:
a Muncie M22 series 4 speed transmission; pro shifted by Liberty Transmissions; backed by a Zoom Dual Friction Clutch; and the gears are rowed via a Hurst Street Super Shifter
The rearend is a GM 12 Bolt; loaded with a 4.11 posi, and kept to the pavement with Lakewood ladder bars

Rolling stock is Cragar 14x8's on the rear with G60 14 Mickey Thompson Indy Profiles
and Cragar 14x6's on the front with 195x70/14's.

Well I don't know what all is needed for the informative parts of the Desktop Dyno,but I hope I gave enough, if not I'll try to find some old receipts, and my actual head flow #'s somewhere. If I gave too much info, sorry, I'm just really proud of it.
