[QUOTE="KennieG52, post: 15648834, member: 162590"] Don't be running your car with that much boost on pump gas with the 4.0L !!! Maximum boost on pump gas should never exceed 17 lbs.!!......How do I know you ask????.....I just blew mine apart with 22 lbs and yes, I have the 4.0L Whipple. Was making 853 rwhp on pump tune and 940 rwhp on C16 tune. Its now apart while we await my new 5.8/5.4 Race Block being built by Livernois. Typical of most fails. No 8 Rod came apart and punched holes in both sides and the top of the block!! Wasn't pretty....lesson learned is that Shelby's stock forged internals are only rated to 750 rwhp. You can take it over that(as I did) but you are only fooling yourself to think it won't come apart very soon! Do your internals now before you end up having to replace the block as I did......its $7,000 Canadian for a bare block. I went to the 5.8 versus my stock 5.4 as it works better with the 4.0L Whipple and also gives you more displacement. Heads bolt up the same, only have to install the proper head gasket to accommodate. [/QUOTE]
