Blair Patrick's latest 506" FE
« on: April 30, 2013, 11:07:29 PM »
Information is a little sketchy on this one at the moment; Blair has promised to come on in a few days and provide some more details.  But these dyno numbers are unreal for what this engine is:



Photo quality of the dyno sheet is poor because it was taken with Blair's cell phone camera.  I have never seen an 800 lb-ft FE except for my big SOHC, and that engine was 585 cubic inches.  This engine is only 506 cubic inches.  That is a very, very impressive torque number.  And the horsepower peak of 911 HP from 6400 to 6600 RPM is also really impressive.

I spoke with Blair on the phone tonight for a while about this engine.  Apparently it is basically one of his Super Stock FEs, but with more cubic inches, less compression, and a smaller cam.  His normal 427-based super stock engines turn to 9000 RPM to make this kind of horsepower.  Compression ratio on this engine is 13:1, and the cam is a 270@ .050" duration cam with about .700" lift.  The idea behind the engine is that the reciprocating assembly and cam can be changed and the engine will turn into a legal super stocker.  The heads are Blair's pro-port Edelbrock heads, and the intake is a tunnel ram style intake with two 715cfm Holleys.  Blair pointed out that the heads and intake were ported and tuned together on his flow bench, to really optimize the combination.

That's about all I know at the moment, but I'm sure we'll hear more in the coming days...

The further flow benches progress it just points out that "realistically" all the individual numbers for head and intake runners flow's are detoured at the plenum not carbs flange. The distribution of A:F to the individual cylinders goes all to hell in the plenum when they are only flowed individually. Smokey discussed it decades ago.  No doubt Blair is one of the elite few that master the FE Super Stock motors

Looks extremely strong.
That would be 1.58 TQ per cubic inch - pretty much twilight zone territory for me - I've never been past 1.4 something.
Looking forward to seeing some details.

Me too, Barry, I figured I was doing pretty good at 1.4 lb-ft per cube...

That is a very bad @$$ piece there. With a somewhat gentle cam and 13:1 and a realistic rpm range it should live a long and happy life... wonder what one would cost to build?... Im also curious how close a person could come with a victor or dove 4500 flange intake instead of a tunnel ram? Very impressive numbers given the displacement! Great job and thank you guys for sharing.

I think that FE would do mighty well in my '68 Falcon.  The horse power is right about where I would like to see it with about 200 ft.lb. of torque than I had imagined.  I too wonder what it would take to reproduce this combo. 

Great work Blair!

Wow, I'd be pretty content with half of that.... for a while. Later, Travis

I wish I had only half of Blair's engine building skills. That is so good getting those power numbers from that size FE. Can't wait to see more details!

Whew! We've been humpin' it pretty good lately, and it felt good to see some results.   Jay summarized it pretty well in his post.  We basically built a "normal" Super Stock 427, but took out compression, added inches, and used alot less cam by comparison to a SS camshaft.  I was hoping to trade off the stock stroke, compression, and big cam for the bigger engine, less C/R, and little cam, to arrive at similar power with greater reliability from the lower operating range.  The unplanned surprise was all of that torque.  I was surprised about that.  I think I hit the combo just right.  This manifold would be too small for a 500" engine at high revs, but it worked great in the range we want to run it.  We really did not set out to make big power with this thing..........we wanted to build as much of a SS engine as we could so the owner would not have to redo anything except the cam, springs, and rotating assembly.  It has 2.19/1.72 diameter 3/8 stem valves, 66 cc chambers that I have spent alot of time on, and just enough of a bump on the piston to get back to 13 to 1.  It has a Swartz/Patrick billet tunnel ram that we built originally for the 427 that we took out of the car, and two 715 CV/CU carbs inline in the OEM configuration.  The small cam has only 250# on the seat, 750 open, and does not even have titanium retainers.  We went with light tool steel just to save a few bucks, knowing that we will change them later.  Same for the pushrods.  It has .145 wall 3/8 one piece pushrods for the time being.  It was supposed to be a test mule, but now we have to figure out how to deal with all of that torque.  The clutch set up will be interesting, and we have to gear the car to operate 1500 rpm lower, so a new third member is in order.

I was happy to see that the chamber worked well.  On the pull Jay posted, we had 30.5 degrees of timing in it.  It made a little more power at 34.5 degrees, but for the intended use, I'd rather run the lower timing with this much stroke involved.  The block is 4.280 bore for later use, but we stuffed in a 4.400 Crower billet crank to give it a little grunt.  The cam is .700 lift, and in the 270's at .050.  It is a mid-grade roller in terms of lobe profiles.  On the high end of streetable, and will live forever on the drag strip.  I'm still beaming about this engine..........then I start thinking about the what if's............some big 7mm stem valves, a little more plenum, a huge cam, and what about carbs............no doubt this engine could top 1000 HP with some changes.  I think I would stay at 500 inches, but I would go as big as I could on the bore, and plug in the stroke that got me to 500 cubes.  Then, it would feel at home at 8500 or so rpm, and the power would come.  I could also open up the heads some for some 2.300 valves.  These heads are "legal" runner volumes of 185 cc intake and 128 cc exhaust, but with no rules, there would be  more to be gained with the same port design with more cross-section.

All in all, it was fun.  Alot of times the "fun" goes away when it becomes work, but on this one, the fun factor got involved.  I also had a 511 on this trip that made 880 hp and 755 torque.  It had Pro Ports, a modified MR tunnel wedge, and two 850's.  A stout engine, but just not as far out on the cylinder heads and manifold.  I should have stuck those 850's over on the 506 just for grins..................

Wow!! That is massively impressive, Blair. Now the real challenge will be the ability to get the car to handle all that torque.I think they're going to need somebody equally as talented as Mr. Patrick, but specializing in chassis! I'm also amazed by the 30* of timing. I know aluminum heads require less...typically around 34*, but that is the first I've seen totals that low. Should make for a very happy engine with a long life.
A couple questions....what block is being used, and did the 4.4 stroke require any hammers to fit? Any hardblocking used? What car is going to be tortured with this engine? I'm guessing a Fairlane?
And please....pictures?!! :)
Very very impressive!

wedge head record?
« Reply #14 on: May 03, 2013, 11:15:47 AM »
... is this some kind of a record for a wedge head without boost?
