Olds 400 W-30 NOS short block value?

[JOZW30]

That era W30 (400 motor) had a cast iron intake. Would agree with $1000 - $1500 or so for value.

For sure NOS D heads would be worth more than the shortblock.

Don't see many NOS Olds blocks surface though, that's for sure.

i wouldnt give over $500 for it.

is there just an S on the vin stamp?

It has LISB with a much larger 588 below it. The rods have 12 point rod nuts with extra meat around the rod nuts on the cap and they have been balanced. The cam has green/white color code marks. The block is a #396026 G F1 and the pistons have ink stamps with C and D on the tops. The GM crate has the same LISB 588 on it along with # 230824.
