Speak for yourself...
how much faster you going to spin the tires on street pavement, with a 514 than a 460.....
Not as fast as you can spin them with a 598.
Oh come on, this is the only place I can be a kid ... Just because you have it, doesn't mean you have to use it all at once.

Very true that you don't have to use it, but sometimes the difference between using it and not is a very small window on the throttle, and that could mean the difference between making to the track in one piece and making it to the hospital in several.

With all the big hp numbers And big inches thrown around in magazines and on the Internet it amazing how desencitized we've become to how much is enough.
Example is Freiuburger over at hot rod throwing me under the bus over only building a 432" boss 429 rather than building say a 557.... Same cost and a bunch more power right?
But what they all fail to tell everyone is the cost of everything else that goes with the manly hp numbers.... Trans, rear, cooling, bla bla bla (read$$$$)
That motor made 700 hp at 10.5:1 with a flat tappet cam and a single 1050..... And I will tell you it would have absolutly punished any street tire made..... So how much is enough?
Ask Jon Kaase about his Boss powered Street Mustang.... He'll let you know...

460= 600hp@~7000rpm's or 521=600hp@55-6000rpm's which one is gonna live longer? I think the stroker will live longer because of the lower rpm's to achieve the same power as the short stroke deal. The engine will be happier at lower rpms with a mild stroker. JMO so flame away!

IMHO, they are both going to last the same. For a true "street" engine, the engine spends most of its time below 4000 rpm with short bursts to either 6 or 7 grand, so it's not like you're doing 6 or 7k sustained. If you want to get more technical, the piston speed of a 4.3 stroke at 6000 rpm is 4300 FPM, and a 460 at 7000 rpm is 4492 FPM, again, not much of a difference.
Again, IMHO.

Hey Al you mean .060 dont you72mav wrote:Welcome.
And go to the proven builds section, or the top here on engine tech. Dave Ohagens build up stickeys listed will get you there.
A 472 .080 overbore X 3.85 stroke and DOVE heads should get you there economically.
Goodluck.
