Since I am not really a player for the big money, I see no risk in posting the numbers from last Wednesday's test sessions.
Engine 1:
Lincoln Y Block, 383 cu in ,4.06 x 3.7. 12.5 compression, Roller cam, Joe Craine ported heads and intake. 750 Holly HP. Score for EMC is computed from 3500 to 6500 rpm Ave torque and horsepower. This is the same engine I ran last year with a different cam and manifold.. It is about 40 horse stronger.
Engine 2:
333 cubic inch Ford Y block 3.86 x 3.61. 12:1 compression Mummert aluminum heads and intake ported by Joe Craine, Solid lifter hot street profile cam.
This engine has been built for a while and sitting in the corner.. With a much bigger cam it made 500 horse and 430 torque, but was not suited for the rpm range of the contest.. The cam is really too small, for EMC, but this was a last minute substitution since the engine I really wanted to take had the wrong pistons sent from the supplier. This will be a very sweet street engine. Flat torque curve and idles like a pussycat.. Yes I do have two engines in the contest.. It has been a thrash.. I am reminded of Jay's 3 car drag week experience.

Sounds like a couple really solid entries!
Neat...
I should do a write up on my entry. Class rules will keep me out of the money but still a cool piece.
-
Nice numbers, Royce. And Barry, I'm sure we would all love to see that writeup on your combination this year. Good luck to both of you at the contest - Jay

Good luck to both of you!

Lot of respect and admiration out to you guys that are doing this because you dig it.
-
Yep, cool stuff even if the engine design itself is quite old.
-
Bob not old... Vintage..LOL The engine is older than I am, and I am on Social Security.. I consider FEs a new fangled design.
Vintage class has 5 Ford products out of 7 entries..
-
Like me, that means I'm vintage too! LOL 8)

I have a T-shirt that says "If things get better with age, then I am approaching MAGNIFICENT!" Been wearing it for a while. LOL Looking forward to hearing some noise next week in Lima. This is the year of the "Y"! Joe-JDC

Nice dyno numbers Royce. We just got confirmation that our engine arrived at UNOH. I haven'y really talked any numbers because dyno's appear to be enough different that until you get the official numbers who knows. We have close to 4% difference between the 2 we use around here. So I've using SAE on one and STD on the other. UNOH appears to use long large diameter tube to get the exhaust out of the room. Did you notice a difference in the power curve from one dyno to the other?

Here is one of mine... chart added
This year's EMC entry is very much the work of William Blair - my machinist at the shop. I have spent a lot of time these past few months taking care of non-FE issues. I gave Willie a recipe to follow, provided the parts required, and have done the dyno work. He did all the machining and assembly.
We are running in "Big Block Spec" class. This has a 470 cube maximum, and scores are from 3500-6500 RPM. They add up the average horsepower and the average torque to get the score - no cubic inch factor in this class. They mandate the use of a catalog Edelbrock head (no Pro Ports), a choice of two Edelbrock intakes, Comp hyd roller cam and lifters, MSD ignition with no digital stuff, and 11.5:1 compression. Valves must be the same guide diameter and head diameter as delivered by Edelbrock. Porting of heads and intake is allowed, but no welding or filler. Carb must be a four barrel with a maximum of 1.75 bores, and mount directly to the intake - no spacers. Headers and oil pan must be catalog parts for passenger car applications.
I am running a 468 - 4.250 bore and 4.125 stroke. Rods are 6.8, pistons are .020 out of the hole with .066 Cometic gaskets. This was not done as a "trick" - it was done because everything other than the block on the engine is either repurposed, or will be repurposed once we are finished. Its something of a scavenger hunt build.
So far the best carb is an 850 vacuum - a reissued piece from the early 90s when I was working at Holley. The pan is a C8AX Ford performance part from the late 60s. The Hooker headers are borrowed from Rod C, and fit a 63-64 Galaxie. Heads are 60059 castings, intake is a Performer RPM, Romac damper and one of Jay's timing covers. Rockers are T&D street, springs are Comp conical with titanium retainers so small they look like ball point pen parts to me.
Cam is a special from Comp with 106 centers installed right now at 101 - yeah it's a bit advanced.
Its a pretty strong running entry so far - I live two hours away from the contest site so I can still mess with it a bit. But because of the valve limits it will not be a player in the class. The FE has to run a 3/8 guide with 2.09 valves, the BBC gets 11/32 guides and 2.19 valves, the BBM gets 11/32 & 2.14 stuff. Puts me at +/- 20-25 cfm down on airflow from where I normally run. Scaling up Kaase's 2015 spec small block winner gets a 1160 score target. I am currently 60 light, and might find another 10 or 20 at best.
Still a cool piece - and look at the torque curve.
Not the best pull - but a good representative

Added a chart to better illustrate.
This thing does not really have a torque "curve" in the traditional sense...

Man, what a stump puller! Nice job on that one...
-
i dont understand why fords have to run a smaller valve than bbc,and bbm.reminds me of bulls gap where my uncle would run dirt track.chevy could run 454s and mopars could run 440s but ford was limited to 390ci.my uncles 390s smoked them anyway.no wonder they had those rules in place.the officials said every time someone showed up with a big ci ford,they ran away with it.thats why they put the 390 limit on fords!

Barry did you CNC those heads? The heads should work quite well with CNC run even with a 2.090 intake valve, especially if you added a 45-47* intake seat. Flow probably in the 320s with CNC program. Joe-JDC
-
Yes we did.
My "normal" Edelbrock head program is probably more conservative than some. We went to a BT head or my head at some point so never chased the normal Edelbrock casting any further. My casting is just at/under 330 cfm with a 2.200-2.250 valve. Putting the 2.090 in there knocked it back by 20ish.

Here it is, All dressed up for the big dance... Could be a hero or a zero.. It has only been run for 20 minutes. No time for dyno testing

Talk about cutting it close!! I'm guessing you could use some sleep about now. Good luck, Royce. See you tomorrow morning.

This beauty needs to find its way into a vehicle.
