NOW YOUR TALKING... put a shift kit in it... and you should be good to go for AT LEAST 500 RWHP.... and the good thing about that is... if you do blow a 80e can be rebuilt by your regular joe mechanic... it seems most people fail at attempts to rebuild 60e.... or you can grab another for cheap from a junk yard...

i was happy i did the switch

 

well thanks man i will do that....but all i want is bout 450-500rwhp....out of an 6.0
