Hi everyone, I have a 69 with a 302 auto.... It sometimes overheats and I am pretty sure it is because of it needs a bigger radiator
Currently has a 2 row, 20" width... Would a aluminum 3 row, 24" width be enough?

 

I would say it would be good. I swapped out my 2 row for a factory 3 row for same problem.

I would check ur thermostat first before changin radiator.

 

Also check the radiator hoses to see if they are collapsed. If they are not, run the engine and see if they collapse at higher or lower rpms. If they do, then replace the hoses with a support spring inside to keep it from happening again.
