Crate Motors
running twin 454's, looking to upgrade power without losing reliability, considering 502 crate motors, I have been told yes, no, and maybe, any thoughts?
Thanks.
Thanks.

Re: Crate Motors
PM Kidnova, if you are thinking about 502 crate motors...
MUCH more to it than bolting it in, but it can be done.
Kid KNOWS ALL about it!!!
At least with a 502/502 in a boat...

I can only assume they are installing their own proprietary cam grinds, installing their specific intake and induction system and electronics. If they are doing something more with them someone please enlighten me.
Also, to date I have'nt heard of any real issues with a ZZ502 being used in a boat.
That said, IMHO if you're gonna take it out and go WFO all the time, or do allot of poker runs, I think some attention to piston cylinder clearences may be in order. But, I guess that would stand for any engine you plan on running hard often.
