Stage 2 bore

[951le]

What is the most a 153 block can be bored safely?

 

[49-blues]

i think that would depend what a sonic test would tell you.

How about this what it the largest bore anybody has heard of with out problems?

 

[Reginald West]

I am doing one at 4.050 and I have heard of them going as far out as 4.090

 

[49-blues]

I ve heard as much as 4.100"-i would call any of the reputeable stage2 engine builders such as dan strezo, cal hartline,duttweiller,bobbie from rpe,nick micale, etc for a more reliable answer.

We went 4.060 with Catagory 6 (950 rwhp) with no problems.
