Well, we are out! Snapped (I believe) the input shaft on 1st time run this morning so glad now it hasn't sold yet, four passes yesterday and one burnout today, not the way I would want somebody getting my car. So need to send my used back up converter in and wait till it gets back then put my spare trans in or get this one fixed first. Will also need to send the converter that is in it now to see if it was damaged, most likely putting the high compression 501" back in and sale the 572" outright or keep for another project to bring the price down, I guess time will tell.
