Gary thanks for calling me today,nice talking to you.Thanks for all the insight.

I hear you bro..

Likewise James, always nice talking boats/motors !!!:grinser010:

Gary, after talking with Jeff the next step is to let him decide how to build the motor. He knows what you want, let him get you there!!

One thing about Jeff, he has more posts, is more visible here than any other builder or any supplier for that matter and I have never seen a negative thread or post about him. That says alot!!!!

Hey Jeff, Merry F'in X-Mass!!

K. I really want to move forward with the new motor, have to sell the 600 first. Jeff and I were discussing the same HP as your motor.

Gary,
PE has a 540 cube with a 2.3L Whipple making around 750HP.
Your 502 cube with a 3.3L Whipple is capable of making the same 750HP no problem. New cam, ignition, brain, turn up the boost.
I'm not sure I follow?
Is it that the Merc Racing 600 is worth enough that if you sell it you can build a custom 750-800HP engine with $$ from a sale?
Either way the smartcraft has to go, right?

Pat,
Jeffs talking about a 598 ci. efi. 750HP is like running it stock. Longevidy is way up there.

Thats pretty much it ...........big cube motor, 750-800 HP, no supercharger, 54000-5600 rpms, regular gas ='s LONG LIFE !!!!Great talking with you lastnite Pat, your new boat is gonna rock !!!! :grinser010::ernaehrung004:

Hey G,
Not much here.

Did you call Whipple or Raylar? I know they can remap the Merc 496 with Smartcraft.

Hey Gary is your boat have regular gauges or smartcraft,if it is wired smartcraft you will need to use pcm555 ( much harder to recalibrate than mefi 1-4) you may need to re-rig dash for standard gauges if engine builder uses aftermarket computer or mefi1-4,just something to look into.Modern electonic control units are nice but can create issues when modifications are done.Merc racing changed there wire harness acouple years ago.
