Scott, I had a similar problem with my 70. The air was cold but no blow. So this past winter I removed the air box on the inside fire wall with the heater core and found that all the seals had turned to crumbs when you touched them and that a diverter door had come disconnected from the vacuum pod. I repaired all the seals and doors and adjusted the doors and now it will all most blow your hair off your head!!! Check it out you may have a similar problem.

Hope you don't mind another so soon. Got part of the answer earlier but now looking for more tricks and fixes. In my 68 Chevelle - Air flow with the air conditioning. It don't blow...it sucks. It has good cold air but air flow is not like I am now use too with these modern systems. Just had a relay put in the line to the fan motor - that helped the fan speed at lot at lower engine speed - changed out the squirrel cage to a light weight plastic with a 325 ( I think ) CFM unit. Helped as well but more puff is needed. Got any ideas. A 600 or up CFM would be good but it is a small box and I am not really into major dollar a/c redos. But I am open to anything. It is factory with an upgraded compressor. Seems mainly just poor air speed. As it is going, since it will be a little on the miserable side in July and August her in Texas, my wrench is going to throw in a new cam, roller rockers, "chrome" Edlebrock intake to replace the one that is not chrome( figures), moon finned valve covers ( boy have those climbed in price since I got a set in the 60's) and I am sure a few other things that will appear on the bill that he has not told me about. He keeps looking at one of his blown 502s and bigger sitting on engine stands in the back room and saying, "it could fit, cept fot a leetle hole in the hood " and a big hole in my wallet. Other than the fun of trying to make something old behave like something young ( yeah, that logic probably had something to do with my recent divorce ) I'm starting to wonder if I should mount the Chevelle body on an entire Corvette running system. Especially going into summer in Texas, any help will be greatly appreciated. You'all really helped on the lights. Running with crappy lights was a serious inconvience, running without good air flow is bordering on human abuse and should not be tolerated. Thanks in advance. I hope to help with answers some day instead of just questions. Scott
