109 3.8 turbo block

[hotairgnx548]

What is the max I can have a 109 block bored. Block is bored +040 but burnt a piston in one hole may need to be bored to clean up. This is a street and strip car I dont want to put the money in it if its going to cause more problems for me. I expect it to be a low 11 or high 10 sec hot air motor when I'm done.

personally I would find another block, bore it to .040 and just buy one piston.

Your already .040 over that would be my limit especially with low 11 high 10 sec power!!

Is a sleeve not an option?

Thanks Randy but I'm going to clean this one up and put some forged pistons & rods in it. For some reason it really went lean and melted one of the .040 over stock pistons. I also have a couple of hot air blocks and a 4.1 on the motor stand that just needs forged pistons in it or just put it in as is it already run 11.40's but I want to use the 109 because I've already had it decked .020 and I want a 9 to 1 compression motor . If the machine shop says the block is no good I'll keep you in mind. Thanks see ya John
