[69 Post Sedan]

I took the block that came in my car (3999290 4 bolt main) in to have it cleaned and double checked to make sure of what I have. When I had my engine builder take a look at it he said the bores were perfect and straight. Initially I was told the cylinders were .008-.009 on the big side. It's already .060 over. If I have to bore it again that would make it 396 +.070 or a 402 +.040. Do you know how hard it is to find pistons that are 4.165 for a BBC?

I have a cast crank and HD 3/8" rods that are going to get completely rebuilt.

The 077 heads should be at my house this week. They are getting checked out and flowed.

The cam Mark talked about in a earlier post is what I am leaning on running which is also what Comp. Cams suggested. 11-770-8 or XR274R. It has good low end torque with steetable manners.

Carb and intake are up in the air yet but my engine builder liked the TM2R with the 3418 Holley.
