I have a '72 LT-1 short block I'd like to sell. I reads "1220CKY" on the pad after the VIN#. It has the correct pink rods, 4-bolt mains and steel crank. I put in TRW forged pistons (.040 over) when it was balanced and blueprinted 30K ago.
Its running great in another Chevy vehicle with aftermarket intake, heads, pan and ignition.
I would consider selling the complete engine (changing to LS-1) but I'm a long time 'Vette guy so I'm assuming that anyone interested in the short block would want to use factory parts on it.
What might the short block be worth?
Thanks,
Mike

 

A .040 over bore with 30k miles on it? Not a whole lot.

 

I have an L-48 engine (2-bolt main) that has .040 over pistons in it. The engine has 208,000 miles on it; 30K since its last rebuild.

I think I'll just stay with it, since its in the car and running fine.

Someone may want that block and hardware from a 40 year-old LT-1 engine for some nostalgic purpose. But, I doubt you get much for it....maybe $200-300, as is. There is nothing really 'special' about that short block that any new parts couldn't duplicate or improve upon.

 

Might be interesting to see if you can find the car it should go with to see if the current owner is interested.

Otherwise it's just a used 350 shortblock...

 

Hi,
I agree that the present owner of the car it came from, (if it's still alive?!), might be very interested.
But, depending on what he, knows/thinks/has been told, is in his car now, he may prefer for it to stay 'missing'!
Regards,
Alan

 

A LT1 motor is worth quite a bit in the original Vette it came in, other wise it's a boat anchor, no one is really going to want a 40 over block with 30K on it

 

Are you kiddy me? I would love to have that. I would put it in my 79 vette. Heck half the work has already been done. Sounds like it just needs a cam, heads and intake and Veroom. I'm sure your at least half way across the country from me. I'm in Pa.

 

We have a winnaaaa......

 

Sheesh! You guys are tough, but I appreciate your taking the time to respond.
The story on the original LT-1 Corvette:
Answering a newspaper ad for a 'Vette motor I got directions out to a rural farm. The Corvette, sitting in the front yard, had been wrapped hard around a tree hard, totaled.
In a corner of the barn sat the LT-t hood next to a short block with buckets of bolts, pushrods, rockers etc surrounding it. The owner, a 19 year old farmer's son, said he had sold the intake, heads, cam/lifters, 4-spd to his friends.
I check the stamp on the block to confirm its pedigree and took it home for $250.00.
The short block went to a race shop to build it for use with a 6-71 blower. When it was done it went into my '56 Bel Air sporting a Crane blower cam, Moroso 8 qt. pan, TRW blower pistons, Trick Flow aluminum heads, topped by a polished 6-71 and dual Holleys. The blower pulleys are 1:1 producing 13 lbs. of boost at 6200 rpm. The dyno coughed up 595 hp at peak boost with 450 ft. lbs. of torque starting at 3000 rpm climbing to 550 ft.lbs. at 4400 rpm.
It went into the '56, Chev, not a light car, making it feel like it had been on a crash diet. Behind it was a B&M T-400 and convertor. The torque was worth the work and $$. In 30,000 miles it needed nothing but new plugs (often) and a replacement set of carburetors. Gas mileage? 8 to 13 mpg (highway). Next step is to replicate the setup with an LS motor.

 

A used 600 HP blower shortblock? Pass...

I would have taken the whole car...regardless of condition

 

I had already owned a '70 LT-1 in 1972. My previous Corvette was a '68 big block (bought off the showroom floor) with some modifications to the engine. It would pull 7000 rpm in high gear with a 3.08 rear end. The LT-1's power was a letdown. I wasn't interested in another one. Plus the frame was bent, no interior, fiberglass missing, no trans or bellhousing...uh, uh.
