I would be more concerned with rod angle than piston speed, and rod stroke ratio.


LS blocks are still pretty rev happy in my eyes. If you never detonate, then motors can live through a lot of stuff that ones expect it shouldn't.



Too many novices out there blow up LS/VTECS because they don't know what they are working on.


I sound like a broken record when saying this, but MINE was bone stock and lived through over 8 months of 8500-8800 redlines on a average 100 mile daily city abuse. The next guy who owned it blew it up (actually spun bearing, rods not broken), probably because he liked the 9200 rpm (mugen chip) limiter too much.


I planned on building an H23/Vtec and running it at 9000 rpms if the cams were big enough. It would of course have H-beam rods though, and either honda or forged pistons.
