Motor rebuilt COMPLETE!!!
hey guys
i just picked up my 427 C5R motor from DRM. Lucky me, im local to him!!! So, it has been exactly 2 weeks since i gave him my motor, and he cleaned it up and fixed EVERYTHING!!! there were a ton of things gone wrong, listed in the following:
rings
rod bearings
main bearings
timing chain & guide for 427ci (had .5" of slop
)
gaskets (given)
oil pump (preventative maintenence)
3 bent intake valves
springs, seats and retainers (previous ones were to large)
ARP crank bolt
fix seats and mill em'
not to mention, that when the heads were ported by MTI, they drilled into the oil passage in the intake side, filled with epoxy, only to crack and allow oil into the intake. this was fixed by each port being welded shut! After being finished, they were bench flow tested makin 330cfm @ .614 lift. Nice for LS6 C5R race heads huh?
so, with all that, i wonder how much hp/tq she will make! she was a monster before, imagine now with proper parts and build...
i no longer have a MTI motor, with all the problems and poor assembly, i am now proud to say, i have a DRM MOTOR!
