Re: Recommendations for cooling of BBC in a 69'
Yep, two strikes against you now that fan and no shroud. Put a factory mechanical clutch fan with a shroud with the fan positioned with the blades centered in the opening, second choice would be electrical using a dual Winstar or similar, they pull a hurricane of air, but you would have to step up on the alternator since they do pull a lot of amps on start up, you can make it easier by using two sending units so only one turns on at a time, In fact I been thinking of converting my Nova to electrical, either system installed properly will work fine though.
