La400

I have an excellent short block, low miles, it is missing a rod and piston, no damage to block. Excellent condition. It is still put together with crank etc. Removed heads for porting and polishing. I would like to get $1000 for it. I am considering since I have not been able to put on overhauled, ported head in selling them. With port flow the increased in HP would be around 47 HP, they are like new, I would need somewhere in the $2,500 range.
Thanks for your time.
