Wonderful thanks.
Btw, How good are these 502/450hp marine long block that's available? Can they easily be upgraded to 500hp with some bolt-on mods? I'm making mine carb.
Thanks

I dont know anything about whatever long blocks that you are talking about. I went long block one time with what I thought would be a good motor and it ended up being a POS. Since then, I dont buy anything rebuilt because you dont know what parts are in the motor...cast or forged. I have also found out that it really doesnt matter what they tell you about the motor...it usually isnt true.

did they by any chance give you a build sheet with the engiine?
if you can, find out what is in it. It should have forged pistions and steel crank. 450hp for a 502 is mild, the question is how did they get there hp rating, you can bolt on some hp with a good exaust sys. and carb & intake, but it would be good if you knew what cam it had.
