You keep telling yourself this

You keep telling yourself every trinket has speed in it.

Engine used to be the worst overspend, but they finally put enough down force on them where peddling isn't a very necessary skill.

He's not wrong. Magic axle, magic shock, magic spring, works too

So many racers, both at the local and national level, are their own worst enemies. They see more power….low friction….less rotating weight….low drag….and their wallets open.

I thought Pierce liked smaller cubic inch stuff than most everyone else? Or was that just prior to changing chassis manufacturers?

[Top Row Analyst]

Actually yes they are. Bigger is bigger.

Yes, that is what she always says!

Nothing new. We've been running a 496 for some 23 years now. Reliable as can be, torque a plenty and gets a hot 8 MPG on regular pump gas in our Chevy crew cab hauler pulling our race cars up and down the California coast.

mcintosh ran that big block buick a few years back and did ok. Theres more economical ways to get 900 N/A

what is the deck height on a wide bore because thats alot of stroke whew

Good point had to go look, its stated at 9.9" MAX so .900 taller than a SBC, thats crazy !

A Wide bore is essentially a Big Block, the bore size is 4.180 to start or so, and can go way up to 4.250

A BBC 454 is 4.250 bore by 4.00 stroke. The bore spacing led to the term Big Block.

So a 480 Vic Hill is larger, 4.25 by 4.25 equals 482 cubes.

I heard Pierce had a 500 inch Engine, but that was a rumor, unconfirmed.

Brodix claims a 4.375 in stroke will fit, and a 4.250 max bore so that would be 496 cubes.

I would think the ROX Block cylinder heads, they would be right at 950 to 1000 hp. Ive seen flow numbers that would support them numbers but do they run it in the car at MAX? not sure.

There was a dude a number of years ago that built a big block aluminum late model motor that made 1100 HP. It was uncompetitive, even at Selinsgrove and Port Royal.

Bigger motors are not necessarily better motors

I remember that engine, built by "EDGE" I think and was run in a "Lazer" chassis. I guess you can go too far, but I find a big block interesting. Jack Pennington use to run a BB Chevy at Cherokee back in the early 90's in his Walter Newman cars, ran good too, but I'm sure it wasn't 1100 HP, that's a lot to hook up. I can only imagine the torque numbers!!!
