should I be concerned..

[SoulSurvivor]

I am going to pull the original 318 2bbl and replace it with the 340 that I built. I built the 340 to 400hp. I want to keep the perfectly working stock AC. Should I be concerned with the AC compressor and clutch assembly spinning @ 6000rpm? Some folks have told me the clutch could seize up.

The compressors don't like to see much more that 5,000 very often.

I got this info from calling http://www.vintageair.com/

Give them a call.

Thanks. You confirmed my concern.

They did tell me that if i went with a modern compressor it would be able to take more RPM for longer, but then it wouldn't look stock like you are after.

Did you get that motor on the dyno yet?

Not yet. I still have to get the headers and ignition system. But I will record the dyno sessions and post em for you guys to see. Maybe a month or two out.

Just shut the A/C off if you are going to 'play'. I have never had a problem with mine.

It's not as easy as that. The compressor pulley is not designed to spin much over 5000/5500rpm for very long. The will and do fail.

Take off the compressor drive belts when you want to play.
