Not getting your point. Since the manifold has a production part number and the Engine Dress Line components are shown in the AIM, it did come close. I don't doubt L70 Pilots were built. The M08 Sport Shift option is in the '69 AIM with part numbers and that never made production either. It happens. My position is that the L70 was intended as an option for the SS350. There is no reason to believe there was any intention to use it on the 302. For whatever reason, it never became a production engine.

Yes this is correct. The L-70 was produced in plant as a prototype job for GM evaluation. Images of this engine with the air cleaner on and off are in the book that was first published back in 2013. |

According to this article, the L70 would make 360 HP!

Was the L70 more than a 350 with trip deuces? Like a higher compression ratio and a solid cam? A 65 HP gain with just a 3x2 induction doesn't add up |

Phil, for clarification, if the L70 was discontinued prior to the Camaro going into production then it would seem like they would have had to be evaluated on the pilot cars, however those all seem to be well documented as to how they were built. Are you possibly saying the L70 engine was evaluated after it had been discontinued and once regular Camaro production had started?

Yes, kind of. The RPO was drawn and then cancelled per the timeline. However here is where it got interesting when a retiree told me "hey I was part of the L-70 build program". In summary These were prototypes built in the same side building where the pilots were produced. These were 3X2 small blocks and were cosmetically dressed with the stripes later used on RPO Z/28. The build happened soon after regular Camaro production started in the fall of 1966. Here is the Air cleaner image close up that I posted in another thread on this topic here back in 2016. |
