90 roller la block advantages & opinions.

I built my motor on that block, sent the can to Bullet racing cams and had it reground, I used magnum heads and new rods and pistons. That should have a block off plate where the fuel pump goes. The cam has a long snout for the concentric. I used factory lifters, Eatons I believe. It's a great motor to build on. I have a 71 360 block here and used this instead.
