New to site - 65 Barracuda

He said that he wanted to use the 360 in his original post. That's why. If he goes big block, he'll have to:

-Change K frame and motor mounts
-Change trans and converter
-New Driveshaft?
-Much less room to work under the hood
-Everything also fits worse under the hood
-Big blocks add weight
-BB's don't seem to make any more power than a stroked small block in a lot of cases
-Will have to alter exhaust system plus new headers

If he stays small block, he can

-Keep K frame and motor mounts
-Keep trans and converter
-Keep existing exhaust
-Saves weight over big block (faster ET's and better handling)
-As long as he has an 8-3/4, he doesn't have to change the rear end. Otherwise he'll need to change it either way if not

So reason to me again why you'd "just go big block"??? When you calculate in all the things you need to make the big block work, build the big block, and then deal with the headache of stuffing it into an A body, I'm personally not seeing the advantage. Don't get me wrong, I love big blocks. But I truly don't see the advantage for the OP to go BB when he already has a SB setup that just needs stroked and head swap. But he can do what he wants.

All good points. And logic. Things is - it's already using an engine plate, front end is customized already, Dana rear, headers now need to be replaced anyway (open headers now - so need exhaust and "mufflers" for events entering as well), trans could probably use refreshing so going with JW SFI bellhousing to handle SB to BB swap, etc

From what we can figure a stroked 360 with even best of heads, cam, etc will get us into 10s. Maybe even close to 10.5. To shave rest still need a power adder. And expensive heads, porting, etc

So .... we've come to the BB option. And discussing stroking the 383. In end maybe tiny bit less budget as well.

You know how "plans" change. Lol. And you're right. Maybe just skinning car from different angle.
