I've built tons of big stroke small and big blocks and they don't seem to ever have problems. With the same parts and in fact any parts an engine with a 4.500 stroke won't turn or make it's power way up high anyway without a huge gogantic cam and huge heads. People are wanting to do these ultra large super big engines since they make the power so much lower in rpm and are in fact lower rather than higher stressed because of the the large drops in rpm required to make the same power. Some people understand this and some don't.
Well except for a lot more tire wear.

I don't understand why you can't rev these 500's to 7k? If Sonny Leonord's 802ci. motor makes max hp at 7100, why is it such a big deal with these? Especially if it's an ERL block. Oh by the way, that 802 made 1417hp at 7100 rpm, N/A, on 89 octane!!!!!!!!!!!!!! I WANT ONE 
. They also have an 898ci. monster that made a hair over 2000hp the same way!!! I WANT ONE OF THOSE TOO

I know what you mean Phil, but the motor he is talking about actually used steel rods, since it is intended for teh street, hence teh lowly 11:1 and 89 Octane.

As Erik said, as long as the head can supply the air needed for a big cube motor, as well as the supporting camshaft, you CAN twist a big motor sky high!
Edit: I guess I was typing when you made your post Erik, or at least I did not see it...and Bruce and teh guys should be calling you this coming week

Wouldn't it be crazy to have that thing in something like the Big Red Camaro. Sorry to hi-jack this thread. Ever since I got my new issue of Hot Rod yesterday I've been in a daze. You might want to transaxle it just to help even out the weight distribution. What, with a M6 that would be good for 1100rwhp N/A. You'd probably go through alot of tranny's, but if you can afford that motor a $6k tranny ain't ****. Big Red would fly, Literally!!!

And that 762ci that makes less power and torque.
And Bischoff engines are known to be some of the best built engines.
Either way though, that 60K or 80K engine must be race gas too then. So still, why such a big difference in price?
Well, Sonny's powers pretty much most of the IHRA Pro Stockers. The only differnce between a full out race motor and one of those 802 street ones is the Rods and Cp. That and the heads, they're like 14k just for a set of semihemispherical 5.0 bore spacing heads. Kind of like some Arias ****... The thing is you need a tube chassis for those 700+ inch motors.
Boy this how rumors get started good god. The motor I listed specs on like flow numbers and such, teh Sonny Leonard motor is a 89 Octane motor with steel rods, and 11:1 and was built FOR THE STREET, it is going in a ****** coupe, again, destined FOR THE STREET The price tag is so high because among other things, the block and heads. Everything on a 800+ CI motor, is basically one off. There are NO shelf parts for these motors. The freakn intake VALVES are almost 2 1/2" in diameter!!!! Those are Sonny Leonard Hemi heads that go for @ $15K. The Throttle bodies are 2 1/2" in dia, and there are EIGHT of them. It uses 96 Lb hr injectors, and this is a NA motor.

doesn't the FTM motor use a procharger though? I can't remember exactly, I do remember somebody posting up that a Buddy of theirs had BES build a pump gas 621 that made like 1100 FWHP N/A, and still had good street manners. It also costed around 34K iirc.
The price on his website for his (BES) 632ci 1,200 hp N/A engine is $24,000. Thats a complete engine ready to install.

Being one off parts for 800+ci engines answers that question.
