470 Stroker - Anyone built one?
I tend to be a believer in full disclosure and my apologies because I'm feeling a little grumpy this morning
In the "it's not that hard" mode - What are your dyno setups? What headers are used? What do these engines have for crank driven accessories on them when you're doing your pulls? What are the water and fuel temps? Do you consider crank scrapers and race type oil pans to be "easy"?
How "easy" is it for the average Joe? I'm asserting that if you take a basic B wedge lower end, a street oil pan with a windage tray, belts driving the water pump and an alternator (we'll assume no power steering), and a set of non-equal length street car headers I can gaurantee you will not see those power figures and i'd venture to guess you won't see the 450rwp or the performance on the track he's asking about.
There's a huge difference in "making *** power" and making results on the dyno by freeing up crankshaft power and you guys know that.
BTW - I second talking to Dan. He's a great guy, a straight shooter, and builds one hell of an engine.
Greater disclosure huh? Factory hemi 6 qt oil pan, factory windage tray, 180 degree water, 180 degree oil. The fuel is at room temperature of the dyno cell. The headers were a dyno set we use for convenience on all our engines, 1-3/4" to 1-7/8" to 2" step headers into a 3" collector. Again for convenience we use a factory water pump driven by an electric motor.
Doing what others cannot do has become the normal around here. We pulled onto the chassis dyno once and the operator said, "What yah got? What do you figure it'll pull?"
Said I, "451 stroker with 906 heads on pump premium, it'll pull 500 HP."
Says he, "You do that and it will make everything we do look like s**t."
It went 528 hp and eventually 554 hp. Too bad about all his s**t.
They laughed at us when the other 451, RPM headed, pump gas engines with Hooker 5209 headers and crank driven water pumps made 585-590 hp on the dyno the day before and we said ours'll go 700 hp.
724 hp.
I can't afford to build my own race car. I'm an average Joe livin' on Social Security and building other people engines when they will let me. You just have to be smarter than the pile of iron and aluminum you're workin' on.
