Stop in for a cup of coffee

that's not a new block that is used on that one, that's a 78 casting number and the water port shape backs that up. But a good core around here goes from 150-500 depending on the year, so you're still looking at less than half. That rotating assembly can be had from jegs complete for $2039 shipped. The heads are just under 1200 complete, roughly 650 in labor costs,cam,intake valve train probably another 500~. plus gaskets. It's a rough estimate but still WAY less than their asking price
yep but its a 70
1200 each for heads..
