Crate 225?

^^ I agree and the reason I'm cautious on just using 'any builder'. each engine has it's own unique build characteristics, so i'd rather the builder have actual experience with a slant

I asked on slantsix.org for a builder in the Denver area ... the only response was a guy in NE and he only does builds during the winter. so if someone local would speak up, that would be great ..... otherwise I'm still looking at a 'crate' myself as I have no engine building skills nor the correct tools to do it correctly.
