'70 Nova L78 (nicely documented)

[deuce-less]

its a 69 car, it's the car that was a stable mate to the 70 car at trm, which you posted
it was less $$$$ than the 70, a better driver choice for me.
the 70 L-78 production was lower than 69, making them a bit more unusual i think

The '70 production was a bit lower, 4,500+/-, compared to the '69 production of 5,500+/-. The 'unique' thing about the '70 version is the TCS and the pancake intake - thanks to the camaro.

Don't forget the dual snorkle air cleaner on the later builds.

The way I look at it, the 1970s basically had a Chevelle LS6 top end.

With the pancake intake? I think the heads were same spec's as the 840's from the prior year & the LS6 was all about the bottom end wasn't it?

RPO-L78 Novas in 1970.....total produced 3765. The L78 top end was basically identical to the LS6 454 motors. Heads were the newer 291's with larger valves..2.19 int...1.88 exh. They both shared the same cam, carb, TCS and low profile intake. The other major difference from 69 was the actual CID of the motor...though labeled a 396, they were actually 402's. Lots of theories on why...I will let others debate that. Some guys I know claim the low profile intake hurt performance and many switched back to the 163 or aftermarket in the day. By the way...I know that 69 green car quite well and one of it's prior owners... almost bought it..sorry I didn't...nice car..good luck!

Never really noticed that the 291's had bigger valves, or that the LS6's had the short intake. Do these differences translate into a noticeable power difference between the '69 vs. the '70?
