I am putting together a TBI 5.7 swap for my 4.3 TBI truck. I have an upgraded radiator and suspension is all done and brakes so I feel confident in upgrading the power. If I buy a Hedman swap in a box with the oil pan… outside of electric fans and the extras that come with the install kit what would I be missing? I know I’ll need a 5.7 computer, upgraded transmission at some point cause who knows how long the 700R4 will hold up… but to get it down the road what am I missing?

Thanks all!

 

With the 4x4 the oilpan may be an issue. Probably needs full modification of the pan and pickup.

 

I know that’s why I was going to get the swap in the box… comes with “everything” needed lol
