Also, your crankshaft will need rebalancing probably, im not sure if im keeping my stock one, i think i will bore my engine a good bit its still in the air right now. As for your block... its the lighest and strongest 4.6L production block that was made.... no point in going anywhere else, its a Teksid, a company in italy who today still makes blocks for ferrari, now don't you feel cool that your car has a little ferrari in it? lol... well almost. oh the hp rating for your block is upwords of 1000whp so whoever told you 600...mmm idk.
