Worth it Yes/No ?

 

who built it? lot of parts in it i wouldn't use, it sounds too cheap to me.

 

who built it and what kinda warrenty?

not that much money for that kinda numbers!

 

Where did you find this deal? I am also in the market and currently evaluating different options. New crate or rebuild of existing assembly.

 

a company called AllChevy

 

I reviewed the web page. Any idea on their warranty or balancing tolerance?

 

i really haven't asked but you can e-mail them the respon prety well. i have asked them many question this way but somtimes it takes a day to get a response.

 

Small shop that custom bulids your motor. One year warranty on engines and blancing spec just ask them.
