L46 Package
Was interested to know if there are any indications on the 69-70 body of the L46 option besides the obvious engine itself and the engine tag near the shifter

Nope, there is nothing on the exterior to identify a L46.
All L46 were manual transmission, shared valve covers with the LT-1, had the 350 hp console tag. All L46 had a 6000 rpm tach redline, which is the hardest item to fake and is often the easiest way to see if a base car has been dressed up to look like an L46. There are a lot of other smaller indicators but those are the items I always look for first as they are easy to look for. YMMV |
Tachometer redline point is the best 'tell' for a real L46. Lotta trouble to fake or find a correct one. The faceplate could be changed, but then the age-fading of the numbers/colors would be different on the speedometer.

The L46 will have deep groove pulleys and an 8" balancer. These can be seen easily and can help verify a real L46 along with tach red line, aluminum valve covers, and console badge.

The L46 had the large copper rad, same as the LT-1. The base engine had the smaller rad with the external expansion tank.

The L-46 used the 26" wide core copper radiator, with attached tanks and corresponding core support, while the base 350 with a manual trans, used the 19" aluminum radiator, with the separate aluminum expansion tank. The 26" copper radiator was also used with base 350's with an automatic trans and/or air conditioning, so the copper radiator in a car with AC, might not be a indicator of a real L-46. The base 350 came with 2" exhaust, and the L-46 had 2 1/2" pipes, but after 50 years, the pipes have likely been changed a few times. |
Thanks to all that responded, great info!

I agree. I have an early 69' L46, it came from the factory with aluminum radiator and expansion tank.
Beware as configurations changed. |
