as the title says, how high can i safely spin my L92(6.2) before you start seeing cam failure, main bearing failure, possible head gasket problems?

228/236 is my cam, stock milled heads, stock head gaskets, ARP head bolts, ARP cam bolts, ARP cam plate bolts, 7.4" comp hardened pushrods, Moroso high pressure oil pump, stock truck intake/90mm TB.

yeah i have brand new LS7 lifters/Trays, cam, pushrods, head bolts, oil pump, o ring for the pick up tube.
by spinning the motor i mean how many rpms can the motor handle.

im not worried with what the transmission can handle bc ill be going with a PB lvl2 tranny with a 3400 converter. i am also on 4:10s now.

i know for a fact the vettes dont red line till 7200 and a lot of guys are pulling to 7400 on 2-3 or 3-4 shifts. i like how my 1-2 is even though it can continue pulling if desired, but im happy with it.

nice man... i think i found the solution to my oil pressure drop problem i posted a thread in this section.. ill install LS7 lifters do i need to change the trays as well?? and LS6 ported oil pump..

i think theyre the same trays but theyre only 8-10.00 each so i changed em. the oil pump will do well
you have to pull the LTs, an heads thats why i wont upgrade heads or exhaust w.o doing both at the same time an since im in there i might as well do a 102 big mouth but thats 4500-5000 ill never spend.

u didnt put in new ARP rod bolts while u had it on the stand???
i personally wouldnt spin anything past 6500 without them, but that's just me.

nope i thought very hard about pulling the motor apart for new cam bearings, balanced rotating assembly, new rings, new main bearings. all wasted money to the average man, but when you want something to last its worth the few lil new parts added to make it last.

ive seen stock 4.8s turn 6800 theyre crazy but who knows.

im honestly waiting to hear 5900-6000 bc the "truck intake stops pulling past that" which i have a dyno graph that shows my truck flat lines at 6500 and never drops a single rpm to 7000.

have you changed rod bolts in yours?.... ive heard horror stories about people changing them with low mile (20k) motors and having bearing failures.
