    5.3 into a 86 K5 Blazer (Advice)

    Hey Guys,

    I did a little research but was wanting to know if you guys could lead me in the right direction for what i will need to make this swap work.

    I currently have a 305 with a 700R4 and it is 4x4.

    I have the complete 5.3, but i need to know about oilpan clearance, motor mounts for 4x4 and what kinda flywheel? What headers will fit?

    If any one has done this swap and has a parts list that would be freakin' awesome!!!!

    Thanks for your help!

    Brent
