A hydraulic roller top oiler will make excellent torque for what you want without temperament-you don't need side-oiling -why spend for it?

Builder said it made approx 550hp. Well, this was NOT what I wanted to hear but it seems this may not be the car for me. The sound of this engine was just music to my ears.

Tip for buying Cobras; don't accept what somebody 'said' it made. If you're spending $40-$100K on something, see documentation on the build and it's testing. Buy something that suits your use too.

I've been in the car scene nearly all my life and I've never heard of "VP C16 fuel."
Dove parts? What happened to all the Ford Tunnelport parts?
Listen to Chas, he knows mostly what he's talking about.  (just kidding)
As to what premium I would pay for a 427 vs any other engine in a BB Cobra that I was considering? The answer would be:
The cost to build and install my new 427 less the salvage value of the engine being pulled from between the fenders.  |

Listen to the folks who have "been there,done that"......your talking about a high compression,very tempermental engine that will require a lot more than the average engine.....
For your stated purposes,if your dead set on a big block car,you'd be much better off with a nice stroked 390/428......
If you buy this car,I'll bet within a year you'll be looking to sell it......

.. then you never heard of C12 and C14 either.
And I've NEVER been accused of knowing what I spoke about-even a little.

I'm guessing jet fuel, but who really cares. I'm sure Patrick will chime in next |

VP C16 is here. Ive used this many times in my 300+HP Snowmobiles as well. Good fuel.

I knew what it was... I was just thinking how much I would have had to carry in the trunk when I took that all day ride earlier this month in order to mix it with the fill-ups along the way.  Not only is it not cheap, but it catches fire and explodes easily.  |

it is less flammable than regular gas! Expensive yes. Instead of running this in my turbo sleds, I switched over to meth injection. Much easier. |

But what I was thinking is that the little trunk we have would have to be full of cans of what essentially is Sunoco 260. You know, the old "dial-a-pump" thing that Sunoco had. That would be a PITA, trust me.... |

It may not matter for your intended purpose, but you'll never be able to stray farther than 1/2 tankful of gas (you have to get home for another dose of C-whatever). While this engine combo sounds pretty exotic, this could become a giant PITA pretty quickly. Then again if you're only planning on keeping it for 2 months, disregard all of the above and plow forward. FWIW.

Maybe that is why Baskin-Robbins has thirty-one flavors!

Not to mention that you get get quite a bit more usable horsepower over and above the (reported) 550 with a semi-docile stroked FE... 482"+.

These guys are right about trying to run a car with an engine built like that.Once stuck a cam in a big block Chevelle after dialing it in sounded very menacing but oh so sweet.Up until about 4k rpm's it was a dog but once it hit the tires always started to melt.Trying to cruise through town was an absolute pain.Back then we were able to fuel up at Sunoco stations.Around here it is next to impossible to get a barrel of VP fuel.

Simple answer
It's a simple answer really IMO.
What does the emblem say on the side of the car slightly above and behind the front fender louvers? 
Here's a hint: What SHOULD be under the hood of a 1969 big block Vette that says "427" on the hood scoop?
Again just my opinion. But then again I AM just a rank amateur. |
