Heyoooo! So I searched for the above, and after about 3 pages of not finding what I needed I gave up and created this thread. I'm sure it's been discussed before. If you don't feel like replying, a link to a post would be appreciated. Alright, so I've got plans for my engine. Question: what's the bottom end on a stock 95 302 good for, RPM-wise? I've read a bunch of other posts on other forums, and they all mostly seem to say 5500: because there's a rev limiter, stops making power, blah blah. Every reason I've seen had to do more with the top end not producing power past 5500 (or really 5000 I guess) rather than a physical limitation on the bottom end. So, assuming the top end can spin to infinity and can flow more air than there is atmosphere, what can the bottom end components (rods, crank, oil pump, etc.) capable of supporting with regard to RPM? My gut tells me that the stock bottom end is good to around 6500 to maybe 7000. Up towards 7000 and beyond is probably stressing the components too much. Thoughts? Thanks in advance!
