525 with bigger headers
 

525 EFI with the CMI header package. I am rigging a boat with 525's that is completely setup for big tube headers and tails that came with the boat. I can make the header flange fit, but my question is: Are Big tube headers 2 3/8" too much flow for the 525's?

My buddy has them on his , sounds bad ass. You will loose a little torque on the bottom end, but worth the sound!

You really should have big huge blower motors with stupid horsepower for that boat. I don't know what you're thinking! :rolleyes:

Keith and I figured it out, if someone gives you trouble, you just tell them wait here, I'll be right back....:eek:

In all seriousness, you are going to enjoy having a performance boat with closed cooling, turn key EFI power. It will be perfect for our little mud puddle.
