Recently acquired a 67 Camaro badged as SS 327. How can I determine if it is a 300hp version?

 

It's my understanding that the 327 engine was not available in an SS Camaro in 1967, only the 350 and 396. The highest HP rated 327 in a Camaro according to the CRG website was a 275 HP 327 (L30). Check the casting numbers and date of the block and the engine stamp pad for engine codes that can be used to determine if the motor is original to the car. If the motor is not original to the car, the engine codes should be able to identify the car model that it was used and what the horsepower was rated at.

 

Thanks for taking time to share!

 

Yeah a true SS will be a 350 or 396,the SS 350 Camaro was the only vehicle to get the new 350 motor in
'67 so it's quite rare. Even the '68 350 is a rare engine only available in Camaro and Nova SS cars.
In '69 the 350 was available in nearly every GM car and truck,I believe the only exception was the rear engine air cooled flat six powered Corvair which was in it's last year of production.

 

1967 should have a cowl tag that lists the options it came with from the factory.

 

Yes, I would agree, but the 4P code was used to indicate both an SS350 and the 327 L30 option, it would be hard to know which came in the car without the original engine code.

 

Yea you have to take into account dates and where it was made but there are some 350 SS not marked and some 327's that where marked. As long as it is not a earlier production car the 4P should be there on a SS. I kind of assumed that if he has numbers matching 327 and he read the above post he knows if or if not its a SS. I was talking about the rest of the options. Normally we just get guys with 67's posting pictures of there cowl tag asking what they got.

I wish I had a dollar for every time someone asked me about their 327 SS. I even got to the point I stopped arguing in the 90's about it. Of course I am not talking about the original poster here, but I have heard every story how this plant did the 327 for a month or it was a secret specials order and the 327 had more power then the 350. There was a lot of confusion because of the 302 being faster then the big blocks and the L79 327 had 350 HP in 1965, add in the 4P thing and I can see how it was confusing. But even in the 80's you could still find an old order sheets for the 1967 Camaro and GM policy was simple its that sheet or a COPO car. Once you picked SS the 327 option was gone. Early production only had the 350 as an option. Big Block showed up mid year.

 

OP...anyone can badge a 1st gen SS. In 67 the 327 4 brl version was 275hp aka "L30" engine. That with the 4 speed was the poor mans SS in terms of performance but was cheaper than a "SS" model. Of course like any SBC those L30's could be modified with cam, headers, bigger carb and head work to really scream

 

I think that 275hp 327 was underrated by GM like so many of their other motors,I had one in an Impala fastback and it moved that big boat pretty well for a mid sized mouse.
Bone stock it was backed by a T-400 and 10 bolt posi with 3.08 gears but it could lay rubber and squawk the tires going into 2nd,pretty good for highway gears and a big heavy car that the Impala was. Wish I had that car back,it was one of my favorites of all I've owned.

 

The factory rating is next to use less. It was a marketing tool. The HP rating is just a snap shot in time and the factory decided where to take the snap shot. The 67 302 is a perfect example. 290 HP at 5300 RPMs. Is what they advertised. 5 HP less then the SS350 that the marketing department wanted to sell. Well 290 hp at 5300 RPMs may not be a flat out lie but the same motor was 400 hp at 7200 RPMS.
