$3300 for a rolling chassis a-body is cheap...if it runs its a steal...check for rust...check the floor and trunk pans...check around the bottom of the rear window reveal molding as well...if its a 2-barrell I would say its probably rated somewhere around 250hp...I work at Year One...so if you need any fine details call 1-800-YEAR-ONE. and ask for Chris at the counter...they'll get me and I figure out what you need and go up to the tech library and look everything up...Good luck with the car man! I have a 70 Chevelle myself I'm about to bust off this weekend!...Let me know!
