Ok Pat if I were to zero in on a bbc (which is most likely what will happen) what direction would you recommend in terms of size and combination? I know I could find a used block and build from there but I'd really rather start with all new components or a crate engine. Also I want something more 500-600 hp. Keeping in mind that at times I will want to drive it on weekends and the occasional car show. Tech mentioned i'm starting at the wrong end. I was thinking to decide on the engine then the trans that would be the best match and do with a ford 9" rear with disc brake and convert the front to disc. I know there are probably other things I should consider but that's why I'm asking for advice from the more seasoned guys. Like I said, any and all advice is welcomed and appreciated.

i still have some mark 6 and 4 core blocks cleaned and mag i can get you out to 512 with any of them blocks with a 9.800 deck. lets think more about TQ then hp numbers it can get to 600Tq and mild 500sHP . now moving up to a dart block 9.800 deck go to a 565 build can do a 582 but i wound start with a 4.250 crank and 4.600 bore or a shade smaller it.s cost would be the same at this point to build a 509 to a 565 flat top engine . after market at this point if you do not mind custom headers then a 10.200 build with a starting point of 572. all engines would use a small rec port head and smaller hyd roller cam custom to my build . so it would be easy on parts and low rpm and make a lot of tq. i done many things to the A body GM car over the years as my 66 GTOs have had many bbc in them 396to632
