I got the Eagle rotating assy. And the eldelbrock 338 hp top end kit. All matched components all work together. I did have my machine shop assemble it. They will have to machine and clearance the block. I ended up with a little over 400 hp and 460+ torque. Around 10:1 compression with the 64cc heads you could lower the compression a bit by going with the 72cc heads.

You could even have them assemble the short block and you do the cam heads ect. Why I liked doing it this way was I knew what kind of shape the block was in and exactly what parts was going into it. And could stop by from time to time and check progress.
