[Pete]

Here are pics of a 5 main 4 banger girdle and crank and a 3 main 8ba girdle.
The intermediate caps go on from the top on the 5 main one.(no webs in the block)
The cost of these is whatever you can get it done for. I don't know of anyone that is making them for sale.
Everything I do on these engines is public info and has been run.
I want to perpetuate the sport. If I get beat, I will just have to figure out something new for next time. Been there done that.
