Hardblock?

[Monte Howard]

Save yourself the aggravation, I hard blocked my 010 block and went .060. With new cp pistons. After the 1st pass the car slowed down. Made about 20 more runs on it. Tore it apart this winter and the cylinders where .008 out of round. And my new pistons skirts where scuffed really bad. Do yourself a favor and just get a SHP block and be done with it.

Best advise ever !!!!!!

I was going to post that as I have seen what you observed with your build but most think I post that to sell new blocks.

This guy found the same thing I found out.

If you want the best, use MasterFlow 885, formerly known as Embeco 885.

MasterFlow 885 has a metallic aggregate, it is non-shrinking and way stronger than HardBlock or the Moroso product after cured.

My rule of thumb if you have to fill the block your using the wrong block,


Cylinders change during heat cycles and and never come back to the original machined size.

So every combo that can not get an aftermarket block should just stop building engines. That is what you are basically saying

go look at the replacement blocks listed by the nhra, and try to find some of the rarer combo's. This idea having to run a replacement block and spend vast amount of money to compete will be the nail in the coffin for many people.

Sounds like your being a dick head LOL

I build a lot of engines with OEM blocks and no problems to date.

95% of my circle track engines I have built for the last 40 years have been OEM block.

Now I am sure you will find something else to cry about LOL
