First hit on the dyno

[Hallzy]

Long time coming here.
Finally got its first run today. Fine tuning and adjustments on Wednesday. It did better than I thought with the Stealth heads.
400/499 Victor intake, Ported source heads, Ferrera valves, Mancini rockers, Smith Bros 3/8 push rods, endurex roller lifters, Bullet solid roller, Mahle pistons, Eagle 4.150 crank, and Eagle H beam 6.76 rods.
11:1 Compression on 91 pump premium.

Those are awesome numbers !! What does the cam card look like ? Carburetion ?

 

[Hallzy]

That's with an 850 carb and to be honest I haven't seen the card but here's what I know
264/271@50
626int/626exh
105°lsa
That was really the very first run no real tuning there probably a few more in it yet I would guess. No work on the intake either there's probably some left in it as well.

Well done !

I will have better information after Wednesday when I'm actually there in person this run was done in my absence.

Nice work.
Job well done!

Anything over 600 hp with unported heads and intake is a win. Was this with pump gas?

It says they are ported heads ! Still very good numbers ! Can't wait to see it tuned !

These heads are ported quite nicely...by hand mind you but the guy is good. Yes it is on 91 octane

 

[Hallzy]

I have to admit I'm pretty happy to see it all in before 6000. I'm sure lots of you will disagree but I think it will live longer this way.

 

[K.O. SWINGER]

Congratulations that's flipping Stout!

 

[Hallzy]

Thanks for all the positive comments fellas it's a pretty exiting day for me. I appreciate any and all good advice!!

550 ft/lbs at 3,500....damn that will be fun to drive.

 

[moparstud440]

Nice combo you assembled there.

Just curious, what block did you start out with?

It's a 1976 400 block with a half fill I had two blocks this one was much thicker everything was right around .200

Dont see too many engine people stroking 400 Mopars, interesting.

 

[345man2]

Awesome build

The 400 is choices around here and everyone is looking for the “right” 400 block. IMO, the B 383/400 is a excellent block to stroke.

I thought the same thing. Isn’t the 400 the go to foundation for all the 451 builds?

 

[Hallzy]

Got a touch more out of it today.
Dyno runs were done with 1-3/4 header

Yep! With a 4.25 stroke and .010 over, it’s a 502.

And 383 -> 496 (4.250" stroke/6.535" rod)
or
383 -> 426 at the stock bore,
438 (4.31 bore, 3.75" stroke/6.760" rod)

So those short deck blocks are worth a little something after all. LOL!
