engine question T1, T4
 

i want to know if a T4 fits in my 72 SB without having to do some remodeling under the decklid, or must i cut till fit ???

It doesn't need any cutting. A stock 2.0 ltr will fit perfectly.

It's not a bolt in deal, there are some modifications needed for proper fitment. You can get a better idea of prices and the modifications needed here- http://www.aircooledtechnology.com/store/home.php
