Hello all,
I have been searching around trying to find the best parts to use for my new 4.6 2V TT build. Anyway, I was searching and came across Coast High Performance who sell many different 4.6 performance parts. They have a nice short block with -21.1 cc dished pistons ending with around a 9.5:1 compression ratio when paired with a 45cc combustion chamber. All forged internals of course. The question I had was that there is one short block with 3.750 stroke and one with a 2.851 stroke, they both have the same displacement of 5.1L. What is the difference? which is better?
