If you are looking at 5-600HP do yourself a favor and just get an aftermarket block. The stock 5.0 roller blocks are very good but not that good.
Maybe the least expensive way to do the block would be a Ford 'BOSS' block.

i was going to get either the big bore boss block or the boss block which is the reason for the thread but thanks for the advice

i always suggest a big bore after my experience with a big bore motor that being my motor I am currently working on. Its a 358 4.160 bore with a 6.2 rod and a 3.29 stroke. N/A It just made 856hp with a small cam made for nascar speedway tracks. You would think a 358 this would be crazy compression and timing but it is only 13.5:1 and total timing of 35 degrees. The reason is the shorter strokes allow the motors to rev faster which for some odd reason (im not an engine builder but I have been told this by roush competition engines and BES racing engines that if you get the motor to rev fast its going to make more power.) increases horsepower.

nice info

Has to do with getting the air moving through the air quicker. Its like having a big huge vacuum that takes a few seconds to kick in to full suck. and then a tinier vacuum that gets right up to full suck its gonna be just as efficient but quicker response. If you understand what im saying

i know the reason for the quicker revving/higher hp combo is that hp is just a measure of work over time.

so obviously if you cant get the work done quicker, that means more hp.

same reason sometimes you can dyno your car after a gear install and actually pick up hp.
