Hello everyone.
Another newbe here to the site. I have a 66 Malibu convertible that I am in the process of completely redoing. As I type the car is getting ready for paint and should be home soon to put in a new motor and complete new interior.
The engine is a 350-330hp crate motor. with a TH350 Transmission.
anyone got any idea what might be the largest tire I can go with in the rear?

Hello welcome to this site from OHIO.:yes:

Welcome. Check the wheel and tire data base in the wheel and tire forum.
Plenty of info including wheel sizes and backspacing.

Hello and welcome Al. Sounds like your Chevelle is coming along fine. Should be ready for the 2007 Chevell-abration.:thumbsup:
