Big Inch Smallblock

The big inch LA is long been in my mind. Several years ago I decided to do it but when I called Rod for the crank he had sold his last one 2 days prior. He said he didn't know when he would get more. I think it would be neat to have a 454" SBM. I would go 4.125 X 4.250. Use would be a bracket car which should get well into the 9s. Certainly finding one would be a problem but I'm sure one will show up but it must have 340 size mains. All I need would be crank and pistons I've got a few rod choices all with 2 X .927 config, a good X block which will go to 4.125. I also could go 4.125 X 4.125 for a 440 inch engine. There's a 4.250 crank for sale now but it has 360 mains. Just dreaming but if the right item comes along I'll go for it. It would be fun!!!
