Points & condenser '65 L84

Re: Points & condenser '65 L84

Late '63 to '65 FI engines have a 55-60 psi relief valve and 80 psi gages.

Oil pressure has little effect on carbureted distributors since the lower bushing is splash lubricated and the upper bushing by grease from the little well below the breaker plate.

If FI distributors have a pressurized line to the pump drive housing (I can't remember), oil pressure could be an issue.

I still don't understand why guys mess around with Melling oil pumps. They seem to be nothing but trouble.

If you buy a Sealed Power OE replacement pump for your specific engine, you should get a correctly designed pump with the proper pressure relief valve spring, which is 40-45 psi for most engines, but if you have a late '63 - '65 SHP/FI engine with an 80 psi gage, there should be a specific callout for that pump, which has the higher pressure spring.

I never understood why Chevrolet raised the pressure on mechanical lifter SB engines so late in the game.

For the prices I've seen asked, I wouldn't touch 'em with a ten-foot pole.

Duke,

You are right, I am a NAPA jobber. If you PM me your address, I'll get the points out to you. I am real curious to see what your findings will be.

John,

I am suprised you are having trouble getting the CS786P's. It may just be an issue of the particular jobber you are dealing not stocking up or asking the warehouse to stock up accordingly. If you like, PM me and I can set you up with some (either the CS786P or the CS89).

Best Regards,

Tim

...sent you an email, not a PM.

Duke, I got a set last year, 112P points and cond for less that $30 and just did the same last week to have a send set. Yes, there are people out there chasing these to the sky, but you just stay away from loco's anyway and they are easy to find. 106P are even easier to find and cheaper, and for my low reving motor, more than sufficient

To paraphrase and old saw... points is points.

The napaonline.com price for CS89 is about 21 bucks and 15 for CS86.

The same parts in other brand boxes through different marketing channels may be priced slightly different.

I consider the current SMP parts to be every bit the equal of NOS Delco stuff from the old days.

Be careful with the M-55 oil pump as the standard volume, standard pressure pump has a 60 psi relief spring. It's perfect for the high oil pressure solid lifter Corvettes. There standard volume/high pressure pump relief is 10 lbs more so it's really not necessary.

I think Melling must make the pumps for Sealed Power because the S/P pics show the M-55 pump.
