360 or 383?

Also, with the 383:

* You'll have around 50 lbs of extra weight up front.

* Piston and intake choice is much smaller, if you find them.

* Less room in engine compartment. (Plugs & headers.)

* You have the option of a built 904 for the 360 that would be about .15 faster than a similarly built 727, if you decide to go that way. (With same converter specs - converters don't interchange between transmissions.) Only 727's were available with big blocks.

Focus on a well balanced combo that's easier to build and reliable.

I vote for the 360.
