How will the stock block react to 400 to 500 hp, thanking about a pro mod stroker kit, engine kit, and 125 shot of nitrous.Can the stock block handle that power???

400 your still in the safe zone but your on the limits.

500, people do it all the time, depends on how well your car is tuned and many other variables. Some people run 500hp on stock blocks reliably, some people split em.

i read in a magazine that they put over 600 hp in a used short block, stock. it held up in the dyno. but any longer? no clue. i just read it in a mag

Its all abou the revs, and the tuning.

best truth right there revs and good tune.

i would reccomend an aftermarket block or a 351w
but i heard that its not how much you can stuff into it, but essentially on how well it was built.

500-580 max by the way, forged h beams, rods and pistons, billet crank, girdles and a motor plate.

a waste of money there as the stock crank rods and pistons i ve seen make over 550 rwhp and last years

dont waste the money on all this stuff until u have a real block= dart,boss ,man o' war...etc..

yea your revs is definitely a limiting factor.

And girdles dont make your block stronger....
