Lookin for help and advice

Me and my Dad are doing a restore on a 88 gt. We got plans on running a turbo set up but we're both new to the whole thing but we also wanna do things right starting from the bottom. I was lookin for a good block to use and we we're kinda set on a r302 but reading around ford racing has a fairly new boss 302 block that i was reading on in this article Boss 302 Engine - 5.0 Mustang & Super Fords Magazine . He was questioning if everything would bolt up together etc... Anyways if somebody could shoot us a little advice our way it would be greatly appreciated. Still deciding on transmission as well possibly a c6 or somethin like the newer cars are usin the 6speed autos unsure on that as well on how it would all work together. Anyways any help you guys could send our way would be nice. thanks in advance.

Sorry for the late reply thanks for the input here and there. Me and him are mostly lookin to keep the car streetable its more than likely only gonna see the strip 3 to 5 times a year other than that just a cruiser. We don't really have any set quartermile goal atm I'm thinkin we'd both be satisfied with 10 sec range. We just wanna do it right. Somethin else we do want though is the twin turb set up just for a little ooo and ahh. We plan on keepin the a/c and trying to keep full interior as well just so ya don't get the idea we're makin a race car here. We know you can pull off numbers with all motor builds but we're not shootin for that. If we can keep it a 302 that's what we'd like to do but if it helps with longevity by selecting something else we may consider. Anyways hope that helps with some more input on our plans. Also do we need to worry about the rear end? will the 8.8 hold up to our goal? We are having it minitubbed I guess you would say atm while the rust is getting fixed as well.
