like Dhadley said, put 93 or newer pistons and rods in your 120-140 looper. well, why not add the finger ports to the block that go along with them :) that should really wake her up. where do I send the block?

You can add them to a V4 but they wont be behind the liner like a V6. There's not room. Youll add them with a ball end cutter and actually cut a groove in the sleeve.<br /><br />Actually, there isnt room for them in a V6 open deck (behind the liner) before 1991. The 91's have the added material to the block casting.

Re: add finger ports? v4 looper

Lets start at the begining. What are you going to do with the motor? What kind of rpm are you looking for? What kind of boat?<br /><br />The shallow finger ports will help but probably not like you think. You'll have to be turning some pretty good r's to see any improvement.<br /><br />What heads are you going to run?
