How similar is an A4 block to a boss 302 block? What do boss blocks usually go for? I found a decent .040 boss block in need of some machining and I'm thinking about getting it.

thanks,
jes

The boss block is the best factory block in a 5 litre you can get. The A-4 is better. The block is thicker, beefier, stronger, rollercam.
Oh yeah, expensive as hell to.
