this is a Q for all you Nova Historians.....

the 68-70 BBC nova's.. are they all L78 or are there some L34 and in 1970 a LS3?

or are they all denoted as L78. which seems crazy/// all were 375hp? instead of 350, 325hp? what about the L72?98? aluminum head option.. which I know there were a few produced..

just seams every one and his brother has a L78 on ebay

BB Novas..

The 3rd gen Nova had the optional BB engine available for 3 years, 68-70. It was a mid year option for the 68 models and had a limited production run, 234 of the L-34 cars and 667 of the L78's. The Nova did not share the same range of 396 choices as the Camaro and Chevelle...both of these cars had the option of the L-35 (325hp) engine and the very rare L-89 (aluminum head) option. In 1970 Chevrolet changed the displacement to 402 (basically a .30 over 396)...the engine was still marketed as a 396 due to the popularity of the 396 branding. The LS3 402 engine was a 300hp version for 1971 ( Camaro, Chevelle, Monte Carlo and Full Size)...in 1970 it was rated 330hp and was available in the Chevelle and Monte Carlo. BB Novas only had the 2 engine choices: L-34 or L-78.

While it may seem there are lots of L78 Novas for sale...many are not what they seem. Real, numbers matching BB cars are still rare when you consider there were over 9,000 of them made during the 3 years of production.

Hope this helps answer some of your questions...

Funny thing is...during the 3 year run of the BB Nova...there were many more L78 cars produced than L-34 models. I guess everyone wanted the high horse car :rolleyes:

Another reason, was the cost wasn't very different from L78 to L34, so more opted for the L78 (i think it was like $50 more). As folks got more and more knowledgeable the remaining BB cars were being saved, typically L34 cars were less desirable even back in the day, so they didn't survive then either. An L79 car could probably out run a L34 car, so that was a big reason why they didn't get a lot of respect back in the day either. (no insult meant to any one).

Now that the L78's fetch sooooo much money they're all being brought back to life. The sad part is most buyers don't know so of the secrets to tell them apart and the dealers/public have learnt how to fake them, with, PING STAMP, PING STAMP. I've kept all the old BB parts I've replaced for verification on my non numbers matching car, incase I want to sell it. I can prove it's an L78 better then anyone could prove it's not with the parts.
