I was reading my 1970 GM salesman handbook today
and in the 1970 Corvette section under engines is
listed a 460 hp 454 ls7.

<span style="font-weight: bold">460- Hp turbojet 454. Available only when 4 speed
close ratio or turbo Hydra-matic transmission is ordered.
Includes full transistor ignition system aluminum heads,
special hood and ornamentation. </span> PRICE TO FOLOW-------------

I wonder if they did produce a 1970 corvette with the LS7????

What dealer brochures/booklets and salesman's handbooks say does not necessarily mean it will go into production cars as this has happened many times with all the 3 big auto makers.

In 1970 the LS6 Chevelle SS 454 was the only time a car outside of the Corvette was the top performer for Chevrolet. In 1971 Corvette made sure this would not happen again as they got the LS6 and Chevelle did not. <<GRAEMLIN_URL>>/naughty.gif

I knew the LS7 never made it to production, other than as a crate motor. I did not know the LS6 was NOT available in the Corvette in 70. Hmmm. That's why I hang out here.

I always heard they couldn't get the LS7 to pass the emission standards.

Interesting. Shown with Air Con - don't think that would have happened with this solid lifter engine.

this is an official letter/notice of cancellation of the various hi-po engines for the Corvette for '70 that was authored after a meeting of the corvette engineering group. This came from Gib Hufstaeder's personal files. I have also included a page from the confidential 1970 Chevrolet Powertrain Features book, which was the preparation document that showed what was &quot;intended&quot; for 1970.

My car is about as close to a '70 LS7 factory car as you are gonna get - it had all the hi-perf go fast goodies GM could sell thrown at it back in the day including a 'CLZ' stamped LS7 crate engine.

It's a shame Corvette did not get the LS6 or LS7 in 1970.
That would have been one of the all time greats for Corvette history.

Friend of mine put a crate L-S7 in a vega. Very first time out of the driveway he stomped on it, that was the last time. After that only 3 wheels would touch the ground at any given time.

A friend of mine had a blue LS6 Chevelle.He put a crate LS7 in it with headers and 4.88s.The car ran 11.7s with a 10.50 slick.It was quite streetable but you knew it wasn't stock.Not many guys wanted a piece of that car.The same car is in a shop not to far from here and is being restored.
I had a 69 COPO Camaro that came with a LS7.Back then COPOs were not that sacred and lots of guys had them modded.It had headers and 5.38s.With L70 Ingelwoods it was a handful on the street.It spit out axles at the track with 10.50 slicks every 4 passes or so.
