5" bore spacing and 12" deck height... 800+ cubic inches.
I'd definitely recommend an original type bias ply tire setup for this.**)

David Kirkham 02-26-2007 12:04 PM

Jack,

What on earth are you going to do with 800 inches! Rotate the earth!

David :LOL: :LOL: :LOL:

ps. I hope you don't try to turn the corner at the 1/4 with that set up!

David Kirkham 02-26-2007 12:05 PM

Next thing you know someone is going to try to put a Merlin in one of these cars!

David :eek: :eek: :eek:

Just taking the more is better thing to it's logical extreme!

Actually, most of the billet pieces we have made fall into this catagory. The current trend is moving to 5.200" bore spacing - heading for 900+ CID. These are Pro Mod motors, similar to the Kasse job earlier in this thread, not at all street oriented!

David Kirkham 02-26-2007 02:12 PM

Jack,

We are just taking weight reduction to its logical extreme.

F=MA

David :D :D :D

If you are going to go to that exreme then put a R4360 in it.
Or a Bristol Centaurus.

My woodworking expert agreed that Poplar is a good stable wood providing the wood was dry prior to glue up into the "billet".

I remeber reading an article many years ago where someone, might have been Bill Harrah, put a Ferrari V-12 in a Cobra replica. He had acquired the engine and figured the Cobra would be a suitable chassis.

Don't tell Carroll! I hope Enzo never knew about it. . .

good morning,

of course the big bore block will be lighter using sleeves - before you press in the sleeves :-)

Sealing of the sleeves was a problem in the 70s as well as keeping them in their position (from turning and dropping).
And also sealing against the heads was.

But I am sure today's manufacturers of aluminium block have solved that.
Keep it in mind!

And how much are resleeving cost vs. re-coating cost when you have to overbore? And who can do it?

What'saCobra? 02-27-2007 09:00 AM

Years ago i recall a mag article about a COB that had an E-type engine installed in GB! Yoiks! Complete with the big pot SU's, would you believe.

i'm sure it can't be found and isn't still installed. Can't recall where i saw it pictured.

How embarassing to a Yank's sensitivities...

David Kirkham 02-27-2007 09:19 AM

Tinker51,

How about a Napier Saber?

Jack,

Yes, that was one of our customers. He needed a challenge!

rsimoes,

Enzo died before it happened.

Gotta run! BIG, BIG day today.

Post Update/Correction.

I just corrected the original post to reflect the correct weights of an original 427 iron block weight and the Shelby Aluminum block.

I Originally posted the original Ford block weighed 190 pounds. Keith Craft weighed one at 204 pounds.

I originally posted, "A cast aluminum Shelby 427 block (with caps) weighs about 150 pounds. (I am giving you that number from memory. I will get the exact weight as soon as I can dig it out of our records)." I could not find the records so I called Keith Craft and he weighed a Shelby block for me at 133 lbs.

Thanks!

David :):):)

Quickjack...are you sure you're not thinking about Harrah's Jeep Wagoneer? The sucker ran back and forth between Reno and Harrah's lakefront compound in Tahoe for years.

Harrah died well before Ferrari.

David Kirkham 02-27-2007 01:53 PM

Jamo,

Actually we DID have a customer put a Ferrari engine in one of our cars! He thought the car was cool and he thought the engine was cool. He said he loved the sound of the V-12. I would agree.

David :):):)

There was actually another one done in the late 1970s or early 1980s. It was red and I think based on a Contemporary. Instead of 4 header pipes coming out of the side and merging into the collectors, there were 6 pipes. I remeber reading an article on it about 20 years ago in a magazine. I think that it was a mainstream publication like Road & Track or Car and Driver.

xlr8or 02-27-2007 03:15 PM

At least my engine was a Ford. ;)

David Kirkham 02-27-2007 06:20 PM

Lew,

You can remember that far back? You MUST be a car nut. Does your wife know about this? I just want to know which you like more--cars or helping your wife at work?

David :D :D :D

No Kirkham for him, 2 years! (to quote a character from Seinfeld)

Jamo 02-27-2007 11:25 PM

Having seen DV's Viper thing, I imagine a Ferrari V12 would look real purty...just don't think it was Harrah. :)
