Well my engine is a basic mild 440 making Maybe 550 hp (not 900hp)and the pushrod failed me and also one of their rockers causing damage. Now, who should be responsible for this (me of course) but i do feel like I spent alot of $$ on weak parts. I hate rude people. I called them and I try to be polite when i call one of these vendors I always start the conversation out with "Good evening (or morning) how u doin today" Last time I called INDY I started the conv that way and the response was "Im busy and other lines are waiting, what do u need" I said never mind and hung up!! Of course I wanted to curse that SOB out. I called HUGHES and got what i needed. Of course they werent much nicer but tolerable. These people obviously dont care about us!
