Big Block Swap

Who cares what you prefer this guy wants to put a 383 in his Duster.

The largest radiator for a small block will cool a 383 and a later waterpump housing will be needed to use the sb radiator.

At this time fabrication skills will get that big block installed faster because conversation mounts are hard to come up with. You will need kickdown linkage, carb brackets etc..

Hooker makes fender well headers for the Abody big block swap.

Yes a big block 727 is needed.

And an Abody 727 drive shaft is needed, original or fabricated.

If you can't fabricate yourself you will need to find someone who can.

This is not a weekend swap for a novice.
What do you mean "A body drive shaft"? Ive got a BB 727 from a B body that i was thinking of swapping into my 74dart with a fairly stock 383. What is the difference besides having to cut it down.
