Big Block Cooling System Questions

The overflow hose should go out to the passenger side. Your bottom hose should clear the filter. You should probably try to find one that fits better. As Matthon stated the proper rad # should be 2949065. If the last two digits are 66,67, 0r 68 then the rad is from a small block car. Big block radiators are rare and getting harder to find all the time. The repro shrouds such as Mancini stocks are prone to warpage. If you do buy one make sure in advance that it can be returned for a full refund. I bought one from Year One and they were very good when it came to returning it.
