Some points things to consider . What are you using it for ?

In my opion ... For street / ease of install... shelby , for abuse / race ... Dove / comp ,
and for all out race... jesel , T&D or should I say for a 10k ,20k,30k

You should talk to a FE builder !

There is a lot more work involed in the all out race units ,
(head removal , machine work )

Depenting on what intake you have , there is work involved
for some of the others you listed , you must inlarge the bores for push
rods . You may need shorter push rods .


The Shelby ones ( nice ) may bolt right up , may use original push rods
but don't bolt at the end like the Dove / Comp ones do .
They use needle bearings I think . Also may be hard to get .

I did not give price a thought as the engine I found is such a rare one ,
it just needed to handle it's poison .
Good luck ,have fun!
