Re: 69 builtsheet
The LM1 and L48 options were the same price [$68.50].
This is true. Makes sense being that they're identical engines except for the head castings on the LM1 having slightly larger combustion chambers for a lower compression ratio. It's a shame IMO that the LM1 option was replaced early in the model year by the L65 350 2 bbl engine (250hp) but the L65 option was much less expensive at $21.10. the LM1 was a very popular engine in NHRA Stock and Super Stock classes back in the day due to it being under-rated by approx 20-25 hp. I have an LM1 clone in my '69 Malibu with a 3.36 gear. With some tuning it's surprisingly quick and runs on 87 octane.
