281 to a 302 stroker

well I need a rebuild , my stock long block made 355 RWHP and 325 RWTQ till it snapped the rod mid beam. expected for 140,000 mile MK8 motor , but anyway I did the math to check the changes in the rod ratio. I also race other brands and my other engines with great torque bands have higher rod ratios and I am a believer in that idea.(a 4.6 stroker just lowers it from stock). I am already using a 3.33 pulley on a S trim Vortech and think I may spend the extra couple hundo's on some other parts I would have to buy anyway. My Mark comes out of the hole like a turbo car and that would save the rear axles anyway, If I wanted to dump the clutch I would have kept my 96 Cobra (too small inside). Thanks !!

A 3.800" stroke (to get 302ci with a stock bore) seems like an awful lot in the 4.6 block. How long does the rod end up being? What the rod ratio? Does the pin end up in in the ring stack? How far out of the bore is the piston drawn at BDC and how stable is it down there?

Given that these engines are really limited in bore -- the Windsor pushrod motor had a 4" bore and a measely 3" stroke -- and the fact that all the stoke in the world will not make up for the limited resultant valve size, it seems to me that all of the money and effort put into a stroker would be better spent on a supercharger setup...
