Default curious: 1971 LT-1 run of mill

while tinkering with my new project.. and waiting on hinge parts I decided to check engine numbers. (1) it is original engine (2) it is the LT1 engine backed by auto trans (think 400?) is this pretty much the run of mill standard small block of that era? seems peppy but then again I'm use to driving a big suv. Thank you (I wanted a big block like I had in a 68 years ago but I'm happy with the small engine so far)

upon further research: appears the CJK was a miss print in the specs or something back then. Just have the 270/auto it appears. Still ok with it.. don't need a tire burner.. just like the sleek looks and at 65+ I can accept being slower. thanks

I don't believe there were any 70 to 72 Corvettes with the LT1 engine produced with an automatic transmission. You might want to re-check your engine numbers. If I remember right the TH400 trans was only available back then with a big block car and the performance LT1 engine option was 4 speed only.

the engine number is: V0215CJK But apparently the CJK did not represent LT1 .. but was printed to do so, but was miss represented by print error. Pretty sure just the low hp 270 model. Thank you

Default T400 Option

The Turbo 400 trans was the standard auto for the 71 Corvette when the auto trans was ordered. There was no other auto trans available.

CJK is one of the engine suffix codes for 1971 L48 350/270HP Automatic... the other being "CGT"

There was a manual that mis-identified the CJK engine suffix code but was quickly fixed and the 350/330HP Automatic nonsense has persisted ever since.

so you could get the LT1 in a Camaro with an Auto - but not the Vette?

thanks.. I can see what mess that miss-print caused. At least I still have the original engine for car even though low side of hp. Good enough for me.

I have no idea whether you could get a Camaro LT1 with auto, but all C3 LT1s were four speeds.

Yes
70,71 & 72 Z28s with the LT1 were available with a M21 4 speed or Turbo 400 Auto. Reg 350s got the turbo 350.
No AC avail at all only in the 72 Vette LT1.

Didnt know you could get the 70 Z with an auto, 71-2 yes.
Great motor with a touch better cam, headwork & long tubes.
Such a shame noone drives these anymore..used to get guys back even then (late 80s) wincing about it being daily driven...they were really starting to skyrocket in value
Fun every day, thats why!! Go buy some insurance and quit worrying-
Off track, just enjoy your ride dont let it sit around!
