Going to the dyno

[BREK]

Next thursday and I'm curious what I should be expecting. Here are my engine specs. 69' 390 .040 je forged pistons, comp 292h, 291c heads mildly ported, somewhere between 9-9.5 c/r, torker (ceramic coated), ceramic coated hooke s/c headers, stock crank & rods, internally balanced, milodon single pickup kit, bulltear nickelplated timing cover with hrc gears, flokooler water pump, hayes billet flywheel 35lb, deburred & polished valley area with bypass line, probably more but thats about all I can remember right now.

edit
I almost forgot harland sharp 1.6 rockers

What carb ?

If Edelbrock or Holley 650, guess 415 HP motor

If Holley 850 cfm DP, guess 465 HP motor

[BREK]

I have 2 carbs to try

1) holley 800 dp mechanical secondary

2) holley 750 dual feed single pump vaccum secondary

[AMX69PHATTY]

Ok, I'll guess 435 HP @ 6100 rpm @ Flexplate
with the 800 DP and a 1" 4-Hole Spacer
and 37 deg total Advance @ 3000
and the valves adjusted properly of course :roll:

i'll guess 440 hp

[BREK]

Well after a few mishaps the numbers are in. Best pull was with my 800dp with 69-74 jets, 110 gas, 36 degrees total timing, and a 1" open spacer. It made 450hp @ 5800 & 440 tork @ 4900

:lo1l: :lo1l: :lo1l:

COOL ! man 450 HP !!!!

:t: :t: :t:

( for ref 800 DP stock jets are #70 & #85 for list #0-4780-2 )

was a 1" 4-Hole carb spacer tried also ?????

Great Brek. Are you happy with those numbers :-|

[BREK]

Yes the 4 hole spacer was tried on pump gas and 110. We lost about 5hp and about the same tork. I am very happy with the numbers, although I would have liked to see 460-475 but hey 450 is pretty darn good for a pump gas motor.

brek,

did you send me a reply to my PM to you ?
if so it didn't come thru for some reason.
got an email in my normal email about a reply
but it didn't show up in my BullTear inbox ?????
Just asking so I figure out if my BullTear inbox is working.

Let me know, Ok ? Thanks :t:

Would be nice if I could dyno mine when it's back together :-|
