Default Mark VIII, to GT block swap ?

Okay, Here's my story. Ive been planing a Mark VIII DOHC engine swap in my 2000 GT convertible. A couple of months ago I picked up a MK8 engine from a local junk yard for $500. I was told it ran perfect and only had 58k miles. Well like an idiot, I just today pulled the oil pan and found a main bearing spun. Im well past the 30 day warranty period the junk yard allowes. Plus it's my fault for not checking the motor sooner.

Anyway, my question is this: Since I have the complete mark VIII engine with a bad block, could I simply swap all the DOHC parts (heads, intake, timing etc) to my GT block? With the mark VIII engine, I have all the parts needed to do a SOHC to DOHC swap. However, how well does this combo work together? what would my compression ratio be?

If possible, I would rather do this then buy another engine, or rebuild this one. Im already way over budget and far too invested to stick with my SOHC.


Thanks!

You would be better off just tossing your 2V crankshaft in.

It has ate the block up pretty good. It will definitely need machine work and a new main cap. Thanks for the suggestion.

Everything will swap but your compression would be around 8.5 to 1, im guessing.
