i have a sparks racing national 440 motor. has been ported by sparks, hvy duty valve springs, ti valves, ti retainers, sparks x4 race cam, carillo rod, hinson clutch basket, pressure plate, 89mm sparks/je piston, hvy duty sleeve, hvy duty cam chain. right center case is cracked. common weaklink in ex motors when putting out alot of hp. replace cases and have them machined to accept hvy duty sleeve and u have a very strong ex motor. also recommend a valve job . motor has 15-20 hrs.
