64 With 365HP, AC, PS where does idler belt fit in here?

[Larry S.]

Have an original 1964 Corvette Convertible with 365HP(Idler pulley)AC, PS and of course alternator. Can anyone help with the idler pulley belt routing. I assume there is a large belt for other componets listed here that encompasses the idler pulley.

Any help?

Thanks

You cut it in half, nail one end to a garage 2 X 4 and use it to hang things. It doesn't go on the car. Are we building a car "from scratch" here?

Larry I don't think you can have a idler pulley on a car with p/s.

Loren,
Thanks for your reply. I had a 64 with 365HP in 66 and it did have Idler Pulley but it did not have PS. Interesting story here. I bought this 64 about 7 years ago. Story was original owner wanted more power, he had the engine pulled and installed a Z430 GM motor. When he decided to sell the car the ad stated original engine available. I bought it 2 owners from his sale. Reading about the original engine available the guy I bought it from did not know anything about it so it was sold seperately before he purchased the car. The car had 6500 redline tach and factory AC so i just recently decided to find a870 motor with casting date would work for the car. I thought I would assemble a 327/365 horse motor and when I get ready to sale it , would be with matching number engine and all component parts casting dates to work with the cars build date.
I have bought several engines from a guy in Ca. and send him an email asking if he had a 870 block with a September 63 casting date. I gave him the full Vin # and advised him the info needed to stamp front engine pad. He called me and said he had the original motor that came in the car. Complete from oil pan up,. Only thing it needed was water pump,exhaust manifolds. This motor had my vin stamped and engine assembly date with the RR suffix for the 64 365HP with AC. I bought it and it should be here next Tuesday. I am exited to go thru the motor and rebuild it to original specs. Although the Z430 motor is real sweet in the car will change out to original rebulit motor. All the brackets, exhaust manifolds, water pump, 7 blade fan etc was used on the ZZ430 motor install. Have you ever heard of this happening? I have not.
Will try to post pictures of the engine. Not very computer literent???

Larry from what I see in the 64 AIM the PS pump goes, more or less, in the same location as the Idler Pulley, section N40 sheet 1.00 & 2.00
The AIM however does not call for removal of the Idler Pulley (or I just could not find a note, like one sees in section L84 sheet2.00)
Interesting story on engine, know I was looking at a 63 FI which the owner called matching numbers and the numbers on engine where however a guy in CA had the original motor. (I Trust CA but not local seller.)

Re: 64 With 365HP, AC, PS where does idler belt fit in here?

Revision B: Rescue the idler pulley and throw away the power steering. No power steering on the HP motors until a running change in 1965 when the 350 HP changed pans to allow the installation of PS. No such option in 1964, ie PS pump no likeee 6500 RPM.
You probably should go buy a lottery ticket THIS WEEK - interject a note of caution here, especially if you are paying a premium for the motor - line up qualified stamp judges to examine the motor when it arrives - I don't know/want to know who you're buying it from, but there are those who would stamp it themselves for extra $$$$.

Re: 64 With 365HP, AC, PS where does idler belt fit in here?

Someone correct me if I am way off on this but..... I recall that PS was not an option on early C2s with a SHP (L76 & L84) engines. Something about the PS components interfering with the larger, 6 qt oil pans on these engines. Have made a quick search of threads on this point but could not find anything conclusive.

After doing some additional research on this issue I did find one internet reference that confirms that PS was not offered or available on 64 corvettes that had the SHP engine.

+1, that is what I have always understood as well.

I have a 64- 365hp A/C car and there is no way P.S. ever could come with this engine. Oil pan will not all the presence of the the P.S. slave Cyl. on any SPHP engines! Check the AIM.

I can't believe your not getting photo's and imprints of the pad prior to purchase of such a major item. In fact a person of knowledge should be looking at it in MHO. But the call and sale does not involve MHO. I can not imagine GM produced 365 horse w/air in big numbers. Yours being a convertible is a big plus. A 365 HP, convertible w/air, super cool combination.

I would have preferred that he gave me the VIN # on the block he has instead of the other way around. I'm just sayin.

My mistake my 327/365 with original motor does not have PS but does have PB and Ac. Trying to post pics of original engine pad stamp.

Re: 64 With 365HP, AC, PS where does idler belt fit in here?

I have had two 365 air cars. No power steering available from factory. You would have to go to a 5 quart oil pan to add P/S. Your A/C compressor should have a special size pulley as well. It is larger then all others in an attempt to slow the revs as they were concerned about slinging belts off. The rr is very rare. Another point is one of my cars had like a 370 gear and the other had a 3:08. Many would say the 3:08 could not be correct with a 365hp but my car was original and it was acknowledged in Noland adams book that some came with a 3:08. Tough on clutches!

Actually, the larger diameter was to slow the compressor speed down to keep from blowing IT up. The deep groove pulleys that were on all of the high lift cams from 57 up where installed to keep from slinging the belts. Your A/C compressor should have BOTH features and I would think it would be hard to find.
