FINALLY this thing will be on the dyno Sunday for NA break-in with a carb.

Here's the combo:
427" SBF using following parts:

FRPP SVO W-351 4-bolt block 2.75 mains
4.125 bore custom Diamond turbo pistons tool steel .927 pins Hellfire rings
4.00 stroke (mystery forged unit but a very quality piece--guess is Bryant)
6.20 Lentz steel rod 2.0 journal ARP 2000 bolts
9:1 compression/Cometic head/intake gaskets
240cc TFS HP heads from Ed Curtis FTI 8mm 2.08/1.6 valves (EV8) with PAC LSx small diameter springs/Ti retainers (look awesome)
Edelbrock Glidden Super Victor 4500 intake converted to EFI with port matching plenum blending
Probe 1.7 shaft rockers
Smith Bros. 3/8" .116 wall pushrods
Custom billet core hydraulic roller cam from Ed 238/244 on 115 .600/.600
Morel link HR lifters
Melling select HV pump
Stef's custom oil pan
ATI balancer
JW wheel

Engine will be dyno'd with injectors plugging bungs and using a 1050 Dominator carb (to fit intake).
Doing this to make sure rings are set and everything pulls clean over 7000rpm.

Last version of this motor was more mild (CNC Vic Jr heads/Vic Jr intake/sl. smaller HR cam) and made about 520s/520s break-in without power tuning and was done by 6200.
Will be using same builder/same calibrated Land & Sea engine dyno and have old dyno sheets to compare.

I'm looking for 600hp NA and clean pulls through 7200rpm.

So, what are your HP/TQ quesses?
I will send a small prize if someone gets exact HP.
Should have vid and pics next week.
Wish me luck, haven't had much so far with this rebuild.
