Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

OK, you 'really' want to put EA to the test...
Heres one for you. This is my Nova small block. Without every detail EA will kick back some silly numbers sooooooooo...

Short block
4.165" bore, 9.000" deck height Motown block

4" stroke 37pound Scat Pro light knife edged crank

Oliver 6" rods, custom JE pistons w/ 11cc dish
Cometic 4.2" bore x 0.039" bore head gaskets
(net 13.29:1 compression)

Gilbertson 12 qt screened stripper wetsump box pan w/ Titan oil pump.

Cam,, almost hate to give those specs away, but there onl relative to this combination so,.. A Jay Allen custom roller. From the CamDr (0.050 #'s)
Intake
open 17.09 BTDC
Lobe CL 110.63
I close 68.35 ABDC
Duration 255.73 @ 0.050
Max lobe lift .4548
net valve lift w/ 1.8 Jesel shaft rockers, .819 (-0.018 lash = .801" valve lift)

Exhaust
open 72.18 BBDC
Lobe CL 115.52
close 21.14 ATDC
Duration 273.3 @ 0.050
Max lobe lift .4444
net valve lift w/ 1.8 Jesel shaft rockers, .799 (-0.020 lash = .779" valve lift)

Heads are a set of AllPro 245RR 23° raw castings built by Uratchko. Valves were plunged in at 17°, 2.18" titanium valves, Exhaust are 1.65"castings.

Flow numbers are:
0.1" = 57/44
0.2" = 123/102
0.3" = 190/150
0.4" = 249/194
0.5" = 298/233
0.6" = 335/241
0.7" = 351/256
0.8" = 365/264
0.85" = 374/-

Exhaust is Lemons 2 to 2-1/8" stepped fenderwell headers, 4" collectors, no mufflers.

Intake is a Uratchko ported Edelbrock RR supervictor developed to match / compliment the AllPro runner. Carb is a single Prosystems Dominator (wet flow was right at 1300cfm if I remember correctly,, looking for that build sheet)

Run the thing on gas (VP C-14) and then I'll tell ya what the Superflow dyno said What I'd like to see is what happens when the motor is converted to alcohol. Still toying with the idea of injection, but it will probably be a toilet instead 'IF' I ever make that change.

I just did my taxes and reviewed my SS statement. Thanks to the current administration it looks like I will only have to work till noon on the day of my funeral.
