N14 Side pipe option

[Jim S.]

Could N14 be ordered on a base engine car in 65,66,67? Could N14 be ordered on an automatic transmission car? Thanks.

Re: N14 Side pipe option

According to the dealer order form, N11 and N14 had no restrictions in 66 or 67. Don't know about 65.....

Re: N14 Side pipe option

The '66 TIM&JG says side exhaust was not an available option on a base engine car with M35 automatic transmission.

Same for 1965 and 1967 Judging Manuals. For 1965 it actually says 250 HP base and 300 HP with auto trans.

I believe Noland's Book on C2 Restoration also has a writeup(s) on this as well.

Thank you, I did not find this in the '65 or '67 TIM&JG. (Don't have a 66 to review)
Does this mean that N14 was available with a manual base engine? Any comments on 65's & 67's?

Re: N14 Side pipe option

Nolands resto guid appears to indicate 67 cars built in 1966 with ECL AC Base engine or L36 with M35

Thanks, I found it in the 5th edition of the 1967 manual however it appears that element has been left out of the 6th edition of the 1965 manual.

Re: N14 Side pipe option

There is a 67 Shriner Car. White/ Blue car that has been for sale a few times. Original tank sticker, original motor well documented. Base motor, powerglide with side exhaust. I have photos of car and tank sticker. It is a real pipe car. Maybe because a special order but they were built. Jeff

In Noland's Book for the 1967 models, he shows that possibly a few base engine (300 HP), auto trans, side pipe cars were produced by GM. However, the 1967 Judging Manual 5th edition does not support this. Perhaps there were a few. Maybe this is now changed with the 6th edition manual.

The message here is if you have one that is base/auto/sidepipe you will likely need some good proof to convince the judges.

Above are copies of Dealer purchase order blanks for 65, 66, and 67. Note the availability to order N11 and N14 options with associated engine/transmission options. Chevrolet may have not "honored" the order in all configurations as shown, but they were at least offered on the purchase orders to dealers........

Re: N14 Side pipe option

In '65 all 250 HP engines had 2" manifolds and also 300 HP w/PG, so GM would have had to have two versions of the N14 options to cover both 2" and 2.5" manifolds, but for '66 all small blocks had 2" manifolds, so there would be no technical reason why N14 couldn't be installed on the base engine with PG.

When enlarged, I can read the 1965 dealer sheet as saying "Available with 250 or 300 H.P. engine" under Powerglide. Under Side Mounted Duel Exhaust, I believe it says "Available with 300, 350, 365, or 375 H.P. engines with a 4 speed transmission.
On the 1966 sheet, I can only see there isn't special notations under Side Mounted Exhaust other than (Off Road Service)
The 1967 is also not legible.

Re: N14 Side pipe option

Here is what John Hinckley had to say on the topic of side pipes:

Interesting, I've trusted the info in 1966 Technical Information Manual to be true in this matter. It says (page 116) that base engine with Powerglide and 2 inch exhaust system was not available with side-mounted exhaust and it will give a total deduction if so equipped.

That's incorrect. All '66 small-block engines had 2" outlets on the exhaust manifolds, regardless whether they had 2" pipes and mufflers, 2-1/2" pipes and mufflers, or optional sidepipes. There were no ordering restrictions on the N14 side exhausts in '66-'67.

After additional research and reading I believe that for the year 1965, base/300 HP engine with auto could NOT get side pipes from the factory. But this changed for 1966-67. Apparently the 1966 and 1967 Judging Manuals used what the 1965 JM had to say on this subject and copied it without research...........and are therefore wrong as currently written.

This makes the most sense and agrees with our experts (JohnZ, Duke, Noland etc). FWIW. I have no dog in the hunt.
