Finally made some pulls on the 527 Cammer

[Barry_R]

This is a "cut & paste" from my post on the FE forum - but I figured that some of you don't frequent that place...

Made 870 horsepower at 7000 RPM and 722 TQ. Absolute top line components throughout - as nice as a Cammer gets.
That's 1.65 HP per cubic inch and 1.37 TQ per cube from a vintage style package.

Billet 4.375 stroke steel crankshaft. Billet 6.700 Oliver rods. Iron 4.375 bore Genesis block. Highly modified welded and CNC ported Coon Cammer heads with raised ports that flow 456 cfm. Highly modified Dove single plane intake with sideways mounted Quick Fuel 850 carbs. Billet .705 lift cams from Comp. Prototype T&D rocker system. Compression is 11.5:1 with custom Diamond pistons, skirt coating and an .043-.043-3.0mm ring package. Crank trigger ignition with custom "T" handle MSD wires. Billet rail Moroso mid-sump oil pan. Meziere water pump.

This is the engine originally intended for the 2009 Engine Masters Challenge, and it was built to meet the rules that year. When we were unable to get it ready for the show, it went onto the back burner for a while as customer projects took precedence.

It was a challenge to get set up on the dyno - the sideways dual quads were too much tension for the old throttle actuator to pull in - it would either hang at 1500 or so if we pulled the return springs - or it would slowly release after 12 seconds or so at WOT. We were able to get clean pulls, but it sounds a bit odd coming in. Still sounds awfully good at 7000 plus!

I did make a couple EMC style pulls from 3000 to 7000 to see "what would have been". With nominal tuning it delived a "score" of 2533 - it would have been competitive for sure. Timing is at 36 locked, and jetting is at 70 square - still very safe at A/F ratios in the high 11's/low 12's. There is definitely more in there - but that's for the next owner.

Sorry bro, aint gonna let you put that in my Cobra, I think it would flip it upside down.
Sweet looking engine, crazy numbers, well done.

[Clois Harlan]

I love that engine. I wish it came in a small block version! I have a 427 in my Cobra but I would love to have a small block version of the cammer in my Daytona Coupe!

very impressive numbers. those carbs look really small!

[601HP]

If I was younger, I may bypass this whole Cobra thingy. I'd buy that engine and drop it in an 'S' code 1968 Mustang.

What an impressive set up. Huge numbers but the one you left out was the $$$s/HP. Gotta be massive!

Barry that's a beautiful engine. I wish I wasn't a mere mortal and could spend the $50K to build one.

[Avmaviator]

That is awesome Barry! What an engine.

I can't wait to see what kind of awesome engine you are putting together for us!

[rodneym]

HO-LEE crap
What a beautiful monster.

I've seen neked girls that weren't that purdy!

VERY nice Barry!!!!!

This motor weights around 630 pounds and puts out about 730 hp the the wheels, what is so impressive about that, my 427 sbf stroker makes 515 wheel hp and weights under 400 pounds, you do the math, its the same output, just supercharge a small motor, all the power, no weight, for an engine competition cool, for street more of a conversation piece

Well, it IS the one WE'RE all talking about.

So, you can't afford it either

fordracing 65,

First, I'm not a ford guy at all, but you are just missing it. When did nearly 900 normally-aspirated HP become unimpressive? Your 427 sbf does not do that - period, period, period. And you're wrong about the "same output" you tout: 730rwhp/527ci = 1.38 rwhp/ci as compared your 515rwhp/427ci = 1.21 rwhp/ci - you need to do the math!

Besides, straight-up, 730 rwhp is more impressive than 515 rwhp, period...

Speaking of doing the math, we can do other math as well - as far as a total car weight goes, assume the same chassis (1800 lb without engine). Say the SOHC car weighs 2430lb and your sbf car weighs 2200lb (correct 230lb difference for engine weights) 2430lb/730rwhp = 3.33 lb/rwhp vs your 2200lb/515rwhp = 4.27 lb/rwhp. The SOHC car beats your sbf car, even with its lower weight, by 22% in hp to weight... A HUGE advantage.

If you want to talk supercharged, keep it even and supercharge both the little sbf and the SOHC and see what happens... I could do the math and show you, but you get the picture

Barry, this is a very impressive engine you built! Coming from a non-ford guy!

[csx4910]

Well Said. You have to respect those kind of numbers. I agree to drop it into a 67 or 68 mustang but the motor would be worth more than the car! (But O wouldn't it be worth it!!)

On the street no way, around corners no way, down a prepped drag strip with slicks, depends on the driver.

You drive a factory 5 right, my engine and trans pack costs more than your car, I like factory 5 cars, but who can't afford it? My kirkham is for sale also.

[Barry_R]

I typed up a comprehensive response but realized that the proper answer to your SBF comparison drivel is a simple "who cares".

[fordracing65]

Great motor, super pricey for 730whp, for an engine competiontion awesome, which is why this was built, a supercharged pump fuel motor, say a 5.4 doch for half the price, same numbers, I have dyno charts also for that, and its fuel injected. Every motor is cool in its own way, this one for me, for the price and weight, not that all impressed.
