Only if the stroke was to the extent that a pin couldn't be fit to a piston would the deck height come into it. The physical dimensions inside the engines are identical AFA clearance for counterweights and rod to rail or cam clearance goes.

Do you have any clue for what it takes to run a 427 @ 8KRPM, reliably? More to the point, do you have a clue, period??

FWIW the IHRA P/S "Mountain Motors"- 900- PLUS cid- turn just a tiny bit more than 5.5K RPM- reliably. How about 2070 HP @ 8100. 932cid. NA. Carbureted.

"If you already have it all sorted out, why do YOU not just do it already!"
I do not have the money. However that has not stopped me from thinking about it! Have you the money to prove I am wrong?

"How do you think that a higher deck would make for any larger clearance inside the crankcase for more stroke?"

I did not say it would. I simply stated that you could have a bigger stroke with the same rods if you read my post.

"Have you ever even seen a TD BBC?" Yes I have. They are nearly the same looking. Easy way to tell without looking at the casting number is the space above the water pump bolt.

"Or ANY BBC??" You are clearly taking this way too seriously and making a post based on your emotional reaction rather than a logical argument here. But to answer your question: Of course! I have a 454 in my van now.

"Only if the stroke was to the extent that a pin couldn't be fit to a piston would the deck height come into it."

So let me see if I understand what you asked.. if you had a long stroke crank you wanted to use and the pin height of the piston was too short to use with any rod that would work, then you couldn't use the crank right? Well a tall deck block might let you use that crank and rod combo you wanted. So a tall deck block would let you run a longer stroke in that case.

"The physical dimensions inside the engines are identical AFA clearance for counterweights and rod to rail or cam clearance goes."

Did I not say that earlier that they were the same?

"Do you have any clue for what it takes to run a 427 @ 8KRPM, reliably?"

I would say that to run any motor reliably at 8000rpm is pushing it unless you have a purpose designed engine like nascar or F1. I was using it as an example, but to run some short bursts up to that speed is not above the realm of possibilities for a 427 tall deck with solid lifters, long rods, stock 3.766 stroke and great heads with huge carbs.

"More to the point, do you have a clue, period??"

I think that is some kind of attack on me, even tho I clearly stated I was simply saying my opinion, you had to throw that in there to try to make me feel bad somehow. I feel sorry for you man, you must have had a rough day, or a rough life, to have to to try to make others feel bad about themselves. Misery loves company maybe true, but it didn't work this time guy.

How much did they spend on that motor is my question? That may be an exception, but I do not think that kinda performance is what this post is about. Why I bet with unlimited budget I could completely design a entirely different motor that beat that. What about the GMC Big Block V6/V12 somebody mentioned earlier? I bet with its short stroke and forged crank I could even make it spin alot of rpms.. Might take some super porting on the heads, custom cams... custom lightened pistons and custom rods... Anything is possible with enough CASH. Dude. C'mon.
