I second that Tod74!! my rev/lim kicks in 7200 & at that point, the fat lady has sung. But at 9000, it really needs to be in someone elses car.

I get to work with 9000 rpm and even 10,000 rpm big blocks often, ..
it's damn cool, .. and can be a fairly reliable bottom end, .. but these are HIGH maintenance engines, .. changing or at least checking valve springs every run, checking bearings often, .. etc, .. and it's expensive. If you really want to do this, .. go to a professional engine builder. Curtis |

Will have my high revving BBC finished soon! 630+ci. Will let you know how it does. Should be running by December. It's taken me about 6 months to build so I'm ready to race!!

crank, rods,(pistons) , valve train,springs (bolts/studs) balance it -if you want a lasting motor - just build it right nascar engines run what all day long??- when you deal with bb, the long stroke is what is so hard on them, keep it all balanced , and im sure it could be done cheep , so many ppl are blowing smoke up ppls asses , just to make other 80,000 builders look good,and to degrade the everyday week end warriors i remember when bb motors were nothing but high rpm engines, and the 283/ 327 /427 's were the high rpm engines-lol so much has changed in this world its funny to sit back ,and see it (my ford is better than your chevy, my chevy is better than your pontiac, my mopar is better)- blah blah blah-lolol no ppl realize there all competitive, with the right combo's |
