New engine setup?

[paulwilliams3]

Ok so I've got a knacked block,good head,good pistons,on 84k
I've can have a 86k rebuilt megane engine or another block and rebuild mine,or can I build a hybrid from the megane lump and my Williams lump.
I'm going on the idea that the they are the same except for manifold!?
Which is better idea and would I get better gains using anything from the megane lump? Cheers

Megane 714 bottom end. Williams head & cams on standard inlet.

Will it give any gains using megane block or are they identical?

If there are gains they are not noticeable. It's jut a better block generally, and slightly lighter. Don't use Megane cams, they are mild compared to Williams ones.
