Tuff Dawg Engines

Greg here - in Melbourne Australia.
Purchased a Tuff Dawg engine crate motor recently.
We ran it for about 30 hours then it let go (blew up) like I've never seen an engine let go before. Pistons shattered, bent conrods,etc.
Contacted Tuff Dawg several times to try and work out a repair or replacement or some solution.
After one short reply from them they have refused to reply to any form of contact. Lousy service.
So if youre thinking about a Tuff Dawg engine CHANGE YOUR MIND AND GO SOMEWHERE ELSE.
I'm happy for you to send them this message and see what reply you get. Maybe I'll get a reply too!

Roller blocks that are setup and ready for roller go for more money among rebuilders. So they use flat cam older blocks with vortec heads and intake or blocks were not drilled for roller running gear.

Either way i agree if your going vortec atleast you should get a good cam setup. It does sound pretty lame to not get a roller setup.

Factory roller lifters are not good for high rpm engine. Flat cams will make more rpm than oem style rollers with stock lifters. If you going for 6500 rpm flat cam will out perform oem roller applications. Now once you go full retrofit roller you can get proper lifters and cams for any rpm range. Flat may still have some advantages but cant see them in a hopped up vortec.

You know Greg, not taking sides or anything but I just called Tuff Dawg, the owner told me that if you are the man that put that engine in a boat then you were out of the warranty period. He also said that you sent them an email telling them that the engine blew up and you wanted a completely new engine.....is that true? First post "raw doggin" an engine builder? He's waiting for you to call him @ 1 (602) 395-0800
