Bill, I know this is not what you originally asked but I have an idea which would be economical & reach your ET goals with ease. Buy Jesse Bigg's Arrow which is in the race car section right now. Drop your small block & 904 in this car & you would have an easy low 9 to high 8 second combo for $6,500 & headers & driveshaft. You could also run that car in nostagic pro stock. If you decided to sell your car afterwards you could probably make money on the deal. I know this is probably off base for you,but think how long it took you to figure out your present engine/trans combo. You would have to start all over again with a big block. Just my
