Hypothetical 475-500hp 360 build cost.....???

You're right. Not a fair comparison. But this is based on what I have and what it would cost me in my unique situation. And, I was hoping it might help someone else get a good idea of the actual cost to build a 360 core they already have to the stated requirements.

The 360 has a truck pan on it... Seller kept the car style pan.

I traded for the 360 and I did infact get a smoking hot deal on the 5.7...

Anyone contemplating a build similar to either one of these would just have to add in the cost of a core engine in similar shape to what I stated.

What's a typical 5.7 core with low miles like 9,000 go for on the open market?
That would give us others an idea if we wanted to go 5.7.

A 73 360 short block like you have should be somewhere between $300-400 I'd think. Others' opinions?
