Need parts application info... Joe Lucia???

[James W.]

Joe,

I need to know what applications a AC 15# radiator cap #RC33 and a Delco-Remy 115 12v coil is for. Any help would be greatly appeciated.

Also, is there any visual differences on the underside between a 1965 and a 1967 small block Corvette hood?

Thanks,

James----

The GM #1115115 coil is a predecessor OR alternate part number for the 1115087 and 1115202 coils. It may have been a PRODUCTION-only part number used sometime during the 1957-66 period.

The RC-33 radiator cap has an absolute plethora of applications. As far as Corvettes go, it's applicable to 1973 through 1982 models.

As far as I know, the 1965 and 1967 small block hoods are identical.

Joe and James....

I mostly lurk over here but I have recently gone through the '65 small block hood issue personally over the last few months, and unfortunately invested in moving some incorrect hoods around the USA this summer during my restoration...

The '65 SB Hood is a one year only hood, the main difference being that there are no slotted cutouts located on the engine side of the hood in the lower left hand corner (near the drivers side headlamp area) which were installed on '66 and '67 SB hoods, only. The slotted cutouts were for attaching the nuts on to the back of the "Corvette Sting Ray" emblem which was used only for the '66 MY car. The '67 SB hood has these same slotted cutouts but the holes were not drilled through the hood for attaching the "Corvette Sting Ray" emblem, again, as it was used only on the '66 MY.

There may be some other discernible differences with the engine side bracing on the '65 SB hood which I read about somewhere, but the easiest way to tell (by far) is to look for the lack of the slotted cutouts in the location described above...

Summary...

The '65 MY SB hood is a one year only hood...

The '66 and '67 MY SB hoods are the same configuration...

The '63 and '64 MY SB Hoods...I don't know this for sure, but I think they may be the same hood with some additional holes drilled for the hood inserts on the '63 MY, but I am guessing at this point...Obviously the hood indentations are the same...I'm sure that someone more knowledgeable than me will chime in here on these MY's...

Hope this Helps...

I believe that the 63 and 64 hoods were different. The recess for the hood ornaments within the forward portion of the twin depressions, present on the 63 hood, was not present on the depressions of the 64 hood.

For both 1965 and 1967 the hood used in PRODUCTION was GM #3857463. It's possible that this hood was slightly revised without a part number change for the 1967 model year, although I was unaware of any change.

Re: Joe and James....

Joe and Rick,

So what you are both saying is that a 1967 small block equipped car should have the same hood as a 1966 less the emblem, BUT with the holes in the front left corner of the underside frame/reinforcment?

Joe any idea about the Delco-Remy 115 12 volt coil application?

Thanks to both of you for the info.

Happy Holidays,

Re: Joe and James....

Joe,

As always, I appreciate your responses...

If the '63 and '64 hoods were different, then GM had a differnet SB hood for all Mid-Years except for the '66 and '67 MY...

The '65 TIMJG - Fifth Edition SB "Hood" Section says the following:

"Check underside of hood for provision of hood emblem typical of 1966 production"...

I learned more about '65 hoods than I wanted to this summer...

One other note worth mentioning on '65 hoods (according to the TIMJG) is that BB and SB hoods had their hood supports on the right side, with no provisions for a left-hand mount...

Always something unique on these cars...

Re: Joe and James....

James,

Yes...

The '67 SB hood is the same as the '66 SB hood on the engine side (with the slotted cutouts), but the holes are not drilled through the hood for mounting of the emblem...

We're saying the same thing...

Good Luck with your Project, and Happy Holidays to you both...

As far as the '115' coil goes, I really don't know much more about it than I mentioned in my previous response. Coil part numbers are "perplexing" because of the fact that most coils were supplied in PRODUCTION as an assembly with the coil bracket. Very often (but certainly not always), the PRODUCTION coil part number, including the number embossed on the coil, is the number for the coil and bracket ASSEMBLY. This is a "wierd" system and I don't know why it was ever used. I'm sure that there's a rationale for it, but it escapes me.

All I can tell you is that the GM #1115115 (the full part number for the '115' coil you mentioned) is a predecessor or alternate part number for the 1115087 and 1115202 coils. I don't know what applications that it may have been used on. From what I can tell, it may have been a PRODUCTION-only part number.
