When was the 1st. 350?
A question for the forum.......I know the last big block was in 74 and I know that in 75 all that has been available is the 350. But...when did GM put the first 350 into the Corvette?

I'm pretty sure Camaros had 350's in 68. Late 80's California Vettes also had 305's.
L82, L83, L98, LT1, LT4, LT5, LS1, LS6 are all designated as 5.7 litres/350CI.(346 CI for the LS series)
The LS2 is 6 litres, LS7 is 7 litres and the forthcoming LS4 is 6.2 litres.

We have now officially veered off the original question. Yes, SEPTEMBER 1968 (according to black book) the 350 was installed the 1969 model year as base(300hp) and L46(350hp) motor.

thats right, in fact that was what I had before the vette
1967 rs/ss 350 camaro with 4 speed. came with chrome chevrolet script valve covers and chrome lid on teh snorkel air cleaner, had a oil fill tube and a wide ratio muncie. deluxe custom bucket interior with factry head rests. Oh man i think im gonna cry
The vett didnt get it till 69 though. 68 was the last year of the 327, and in fact it was a 1 year 327 with large journals, yeah you guessed it the same as on the "new" 350. So a 68 327 can be coverted to a 350 with a swap of pistons to change the stroke ( wrist pin is in a different location)
Thats what i have in my 68 now
