Broke in today on dyno
Goin for pulls tomorrow


4250 eagle crank
7.1 rods
70 over diamonds
9.5:1 compression
240 trick flows
Sick pack intake
Tti 1 7/8
6 pack
Firecore wires / dizzy
custom mild comp cam
600 lift
Split duration
Hydraulic rollers
1.5 hs rockers


Any Guesses

Losses through stock manifolds Monday or Tuesday

559 hp

Did I read that right. .070 over 440 block.

605 HP, 650 TQ (with headers). I don't think it will like the manifolds.

Lol sleeved

Need real/complete cam specs.

My guess is, it will make peak power right before the valvetrain gets unhappy, unless the duration is really short.

Between 525 and 650 HP, depending on the cam.

You took my guess

With headers it should make easy 575-600 with almost any mild performance cam

With the exh manifolds about 525 to 550. Good luck , Ron

First pull resulted in poor attachment to dyno

Fabricating new mounts ..
may have been tractor supply grade 8

Constantly learning
and regaining common sense . Lol

A fat bar with a couple of holes going to the lug on the right above your mount might help. That would tiie your mount to a second lug.

New mounts fabbed
Uncorrected hp 672
Centers 65
Outboards 89/91 staggered
Time to play with jetting and timing and
Secondary springs

Lean in middle due to six pack bog

Rejetting to 92/94
Keeping timing at 35

Wish i could poke holes in my nice ttis and do individual
EGTs to see if staggered jetting is valid .

I think we got a monster on 90 pump fuel .


Great guys workin with me .. takin a break and
Rejetting .

Watching the outboards open and suckin in 55
degree air is cool .
Stll got 1500 rpm and plenty of adjustments to go

Install aircleaner set up?????

got a chance to talk to dave dudek yesterday at the NMCA race at indy and he showed me a chassis dyno sheet of 699hp at the wheels. i'm impressed about what guys are doing with these old '60's engines.

Well im cheating a little with the trickflows

Regardless
Air cleaner , great idea

Then were doin cast manifolds
With 2 1/2 h pipe .

Did good at 66o hp corrected

Then the builder wants to try 850 quickfuel on
performer intake .

Performer or Performer RPM ?

Will bee interesting to see the difference with HP Manifolds

Very nice. You know you've got nice testing conditions when corrected numbers are lower than actual.

Was the intake manifold modified?

Great results! I was surprised to see the size of the outboard main jets. Those are 10 sizes larger than what my 493 with similar sized cam & Indy EZ's likes according to my wideband. I do run the mechanical DC Holley's.

I bet his are .089" and .091" holes in metering plates. That would be about the same as your jet sizes in metering blocks. Decades ago when I raced with the mechanical carbs at least 4 times a week I had three outer metering blocks with 78, 80,and 82 jets. I could swap them at the track a lot quicker than switching jets. Usually ran 78's and 80's on warm days and 80's and 82's on cold days. 64's or 65's in the center.
