As the title states, got this block as a part trade for an '89TTA about a year ago. I took the heads off and that's about it. Block is complete and came from a wrecked Grand Sport Vette with right under 30k miles. Included is the complete rotating assembly, cam & lifters, timing set, cover, oil pump, pickup, optispark (although the cap may have been damaged moving it here from Connecticut), and the water pump. I may still have the LT4 valve covers as well, and this motor has a flexplate attached, you can have it as well, I have all manual cars. I was gonna build this block up, but have too many projects going right now and still need to get the Z running, so best offer will take this motor. The stock vette oil pan is damaged, probably from moving it back and forth, but it was that way when I got it. No signs of internal damage whatsoever, 4-bolt mains of course, no indication of spun bearings, etc. Give me a call @ 904-327-7863 if interested. I hate to get rid of it, but it will be a long time before I can utilize this, I'd rather see someone here locally make this 'tard run and put it to use. Thanks.

 

not sure the worth, so 500?

 

Guy backed out w/bid of $1000 without seeing the motor. Highest offer thus far is $600. Thanks for the inquiries guys.

 

Im somewhat interested, if nobody else takes it you can shoot me an e-mail. I would probbaly go $500 on it, especially if you had the valve covers.

I would have to look into it to be sure. I have my 400 block that goes to the machine shop next week, but its bare. I know that i would have to buy new pistons but if I can get information on how tough the crank and rods are, in the LT4 I may go with that. But if I have to buy a complete rotating assembly for that too, then Ill probbaly jsut with with my extra CI.

 

Sold!

 

Why would there be a flexplate for an automatic when all LT4s were stick shifts?

 

From what I was told, the person(s) whom I traded this motor/car with had the full intentions of using this in an auto-equipped pickup, believe it or not. After loss of interest and a turbo buick/TA liking is why the went with the deal I laid them on the table. Ain't often you trade a complete LT4 longblock & cash for a turbo trans am, but under the circumstances, I couldn't pass up the deal. The car had severe front subframe damage that would have cost me a fortune to replace.

In short, the flexplate was installed in prep for this motor going into a truck. I received the motor complete, with the following stock components attached: heads, oil pan, balancer, timing cover, optispark, water pump, and said non-stock flexplate.
