Before i think of attempting a swap i was wondering what potential the 366 has? are all the bolt on parts interchangeable with the 454?? Do they make race cams for this engine?

 

as far as brackets and such they are interchangable so are intakes
and cam you can have anything custom ground
hei dist. works in also

I just put one in a 98 chevy pickup

 

I thought the 366 BBC was a tall-deck block? Requires different intake or adapters to run a regular intake. Might (should) make a difference on the distributor too?

Seems like a lot of motor (weight-wise) for so little cubes when 396/427/454/etc, take up the same realestate and will make more power. Kinda like the 305 vs 350 debate I guess.

 

You're going to have more modifications than normal if you want to use a tall deck block in a third gen. The 366 (6L) has a smaller bore that the 427 (7L) truck block which has the same bore as a 454. This smaller bore doesn't give the 366 tall deck as much potential as a larger bore BBC. Everyone wants the 427 tall deck block but nobody wants a 366 block.
