Another guess the Dyno Numbers

What does "slightly worked" heads mean? What all was done to them?

Was the static compression ratio measured, or is the 10:1 what was printed on the box of pistons?

Who's dyno will it be raced on?

Exhaust ports gasket matched, full radius valve job, changed the chamber from 62 to 64.5 cc’s, bronze valve guides,

All,
I have an 367 going to the dyno and thought that we would play guess the Dyno Numbers! Kammer Racing builder.

367 cubes
10.1 comp
LAX heads 2.02 slightly worked
XE 274 comp can flat tappet
FiTech TB efi
Rpm Airgap
Roller Rockers
35 degree
1 5/8 headers
80 degrees high humidity
170 degrees coolant temp
91 octane pump

I’ll post the results on Monday.
Thanks
Marion

Did you test a carb and TB injection?

Isn’t the compression a little high for iron heads and 91 octane?

I’m going to say 425 hp 400 tq.

Nope. I’m running 10.2/1 2.02 J heads on my 340 that are slightly ported on 91 non ethanol pump gas with NKG BRK6E plugs with no problems other than a shitty Cloyes true roller timing chain...
 
The engine was disassembled , inspected, machined, calculated compression and verified, assembled and dyno ran there! All in house! At Kammer Racing in Dayton Ohio. Former Chrysler sponsored race team. NHRA Stock winners 70/80’s. Used to set at the table with the likes of Dick Landy.
etc! A no joke place for race engines in the area.

Yes , good question!

I hope the carb had some effort of tune and setup for this engine. Understand that fuel injection was the goal and dyno is expensive. But would like to know if there was some tuning effort in the carb to give it a fair chance.

This is not what this discussion is about at all. To your point a 650 was used for initial breaking and then tune. Then the fitech was slapped on. The engine speaks for itself.
 
385 Hp @ 5500, 410 lbs @ 4600
 
On a dyno, is there ever a measurable difference in peak hp/tq between TB FI and a properly sized and tuned carb? In theory, shouldn't they be the same? Both are just a fancy mixer valves.
 
I got a 274 cam in my square body truck…I think it made 360 hp with 9:1 and pocket ported factory heads…so let’s add 15 for your point of compression and 20 hp for your heads…so I say 395 horse on a decent dyno…

Seen some disappointing dyno numbers that had a Sniper setup. Don’t know if it was FI or other parts of build.

Wondered if we could learn from this dyno experience with your parts combo. Or if you learned something.

You posted the parts of your build.
