Expressman; I have not had an optimum steel block for 4 years, we have two aluminum blocks and three semi motors. I am however, building two steel block engines for this season. The rules at the tracks in our area are steel block. I want to race where our family can enjoy it as a group and for that to happen we need to be able to race the Mountain and the Bird. The extra weight is difficult to overcome; I have never been able to get the steel cars under 2380 and that was with a lot of light weight suspension. The rules dictate iron blocks.
I think you can machine about 65 lbs off one of those aftermarket blocks! Bringing it down to around 30 lbs difference! Call Chris at Edge racing engines. He did that to one he was using(814 525 1355) And I don't think it compromises anything! But really ....all for not! Look at Marion Center Speedway! The most sucessful track in that area! In business for 48 years running! I don't agree with a lot of things there....but even they have a Superlate class! And a Steelblock class! These tracks need to move along with the times if they are going to reopen ! Why buy a new computer and put windows 98 on for the operating system! Personally My classes would be Superlate....Crate late....Purestock....and 4cyl!
