Quality SB engine builders

My friend just had a 340 built and dyno tuned at Gor Den Racing engines in West Seneca NY.
He was very happy with how it turned out.

Also J&L Performance racing engines in Lancaster NY
and KTR Racing engines in Cheektowaga NY

These are the ones I know of local to me. KTR did my 318 in 2007 and it still runs strong.
Just saw you were upstate these places would be a good ride for you.
