For a street/strip and/or race only motor applications, in what ways and why are the aluminum main caps better than steel?

Yes you do, we met when I came to your house to buy the a girdle from you and bought an nos bottle as well. You were also gracious enough to show me your shop and car, and you also hooked me up to moparts.

My Cuda is 3/4 finished with a 4130 full tube chassis based on a skinny kid copy of a design. Double frame rail very similar to an IHRA prostock chassis. With my full time job and my business I have not worked on it in a long time. I hope to free up some time soon. But as you know our economy is much better than our counterparts down south so I have to make the cash while the gettins good as they say. I am so busy I just hired another full time road salesman. I have been racing gokarts with my daughter pretty much year round every two weeks for the past three years. So I still get my fill of fun times. I miss the adrenalin of the drag car but not the waiting around between rounds.

Well it may just happen. Been talking to a few guys and it looks like there is still enough interest to resurect this thing.

Nope never got paid a cent, so I will take it another direction now. This time it will happen and you guys will get the product that the budget racer needs.

We prefer aluminum caps on stock blocks to help with with shock loads in the main area.Funny thing though is that we have used steel caps also with no problems. We have always had our aluminum main caps and seal retainers made here in the USA. Sometimes were our out of stock but can always have them in a short time.

Have a friend who runs Program cross bolt mains in a 440 block ,he has had no issues so far,,,,and i run ali caps in my 440 ,,again no problems so far ,,,,I think its about how good your machine shop is that will determine the failure rate of both set ups....thats my take on it for what its worth

I have Pete's (Best Machine Racing Engines) aluminum caps on both my 400 blocks.

In terms of design, it looks to me like the BCR standard replacement and the Best Machine caps are very similar. However, IIRC, BRC used some type of 6061 vs. Best using a 7075-type aluminum. What are the pros & cons of these two different materials, everything else being the same?
