Tell us about your Corvette: 1971 Coupe that's been in the family since new. Was "stored" in a shed in New England for22 years. Even though I have limited knowledge and experience, I'm doing a body off restoration. Standby for many questions!

I hear all that you're saying and believe me I am NOT convinced yet that the existing beams will hold the load. The beams are already part of the garage's structure and look to be commercially made since the lines between each of the eleven 2x6s are compressed so well that they're hard to see. The final dimensions of each beam is 6"Wx16.5"Hx20'L. As to the type of wood, I just don't know. I'll have to check and see if I can find any markings, but at least it doesn't look to be pine. The spot I'm thinking of making the lift from is 6' in from the end of the beam, so it's not right at the 10' center which should afford a bit more strength than if I was lifting right at the span's midpoint. In addition to bracing the sides of the beam to add stiffness, I might also add some temporary 4x4 posts about 3' on either side of the hoist to take some of the load.

Maybe I better find the guy/company who designed the house & garage 15 years ago and see what the design load was and whether or nor it'll take the additional stress. Failing that, I might just have to find another wood beam/truss products specialist and get his or her input...
