The average 408...

I don't know, I plugged my crap into camquest and got 633 HP. I know my **** doesn't make that mainly because it's tired and it wasn't put together as a max effort mill but when I build the stroker with real pistons and an uncomprimised ring seal I should make 600 HP. According to camquest though I can make over 700 HP with my flat tappet cam and over 800 with a roller.

I'm not sure my stock block is going to live under those numbers.
