The Bottom End

[HuKares]

I'm looking to build an new engine for the 'stang this winter and wanted to get some ideas on building the bottom end to handle what I want. The 'stang is a '66 with the original 289 although I have access to 302's and 5.0's also. I plan to build the engine naturally aspirated for now and then add a centrifigal supercharger to it later. After I add the supercharger, I'd lke to produce something like 500 to 600 hp. My shift rpm's would be about 6500 the way the rest of the car is set up.
My question is how I should build the bottom end for this. Would I be able to use a stock crank? What rods are enough?(I have access to some 5.09 cat h-beam rods for cheap) and etc.? Would I be better off going with a stroker ( I drive the car often so I doubt I want a 347 with the oil control and wear problems)? Thanks for any help,
-Brian

At 600 HP the cat rods are really boarderline ... You need the good stuff at 600 HP.
And maybe i didn't understand but you plan on slappin a blower on a 289 and making it crank out 600 HP ??

600hp with stock rods is not a good idea. If you want to turn 6500rpm's I would use arp main studs, and rod bolts with a nice set of rods. I would also have it ballanced to the 28oz not the 50oz. At 6500rpm the 50oz imballance will put some strain on your mains if you do it all the time. A main girdle would be a good idea incase it lets go, it will help save your expensive parts.

One more thing 347's do not have a oil control problem. Will people please stop posting this
