Thread: Why my car lost 3 tenths last race

Tweet

Pat, I bought this engine used so now that I have it apart it is going to be rebuilt with all good parts and whatever needs to be done as far as machine work goes. I am going to get new pistons now because all of them have this damage (No need to cheap out now at this stage) just need to wait and see what the machine shop says about the cylinder walls to see about bore size. Thanks for your help and input on this.

Finally getting things done on this rebuild. Block had to be taken out another .020 because of damage obviously so I went and saw Bill Miller (his shop is local) and am having some custom pistons made. He is not the way to go if you are doing a budget build, had a little sticker shock, but I am getting his wrist pins too. Erson is also local to me also and they helped me out with all new valve train components and were really great to work with. So hopefully motor will be back together at the end of the month.

all guys a deal with. you could of used a shelf pistons and would of been abit less ???

Pat, from what I have read online (I know not always good/correct info) and my own research the heads I have would not work with normal open chamber pistons. I could be wrong, but that was the conclusion I came to and that is why I am having BME do the pistons. He just scanned my old Ross pistons and is making the new ones to the new bore size 4.580. I could not find many shelf pistons in that bore size, summit has some JE in that size and the price of those compared to the BME would of been pretty close. In fact we are going to use the JE rings because it was hard to find rings for the bore size. I also went with BME because it is nice to do business face to face and like to support local businesses when possible.

well i just did a 4.580 bore bow tie block. the guy had the pistons so i bored and hone his block and rings are $$ and from what he told me that JE is the only one that sells the ring s ? hard to say i never look in to it for him but told me top rings are $20. each.i told him to look in to a total seal rings as in the past they have had off size bore rings . any ways i would of used a 4.600 bore piston i do not know what chamber you have but i sure something could of been made to work less you have a odd size rod and stroke
