Just sending a shout out to compliment a local engine builder. He sells alot of motors locally to racers in the area. I highly recommend his motors, I have never had a problem with them. He has a very nice, clean, and fully functional machine shop, (and I mean scary wipe your feet clean). He dynos his motors on sight and will let you watch. His attention to detail is second to none. I have called Mark on several occations to ask advise and he is always willing to take the time to help out, I highly recommend him to anybody wanting to purchase a turn key BB chevy, they are amazing. His Ebay handle is Vortecpro, and his TC handle is mike1231. Check him out. Thanks.......
