Which way to go? Opinions...

Hey all. My first post on here. Sorry if it's long winded.
My project as I got it ten years ago : 71 Scamp with Dart nose. Basically stock 77 or 78 440 with TM7, 509 cam. 8 3/4 , 2.76 open. Scumacher kit. Stock 727. Been sitting untouched for about 5 years. Other priorities. I'm finally in a spot to get going on it. My original plan was do an all forged rebuild on the 440 and go small turbo. Fun street car. Recently I have found a couple things on CL that he me double thinking. One is a set of Indy EZ's, same ones in IQ's sticky post, used with about 6000 miles complete kit as from Indy. Stock port. Basically half price at 975. Also found a 530 casting 400 block with main studs installed. 250 obo. So......
493 with Ez's? Aluminum caps with studs. Already have the block as long as it checks out good. 470 with Ez's? Mostly street car with occasional trips to track. Did my research here and other sites, just really undecided which way to go. And of course budget is a concern.
