sbc aluminum 303Hp & best auto trans

Project - 1970 Camaro one owner
Looking to build a quick streeter with decent gas mileage (13 mpg sux!).
Searching for a low mileage aluminum 303HP smallblock that will hookup to latemodel auto tranny. I would appreciate tech leads on How To source the right parts.

I am looking to run stock motor (with headers, chip, cold air pack), gears and slicks for 1/8qm@8.25et.

Have stock internals goodwrench 350 (manifild, 650cfm,headers,recurved dist,battery in trunk, slicks, loose converter, elec fan) in it now and run <2sec/60 ft -- 8.96 best and 9flat consistent 1/8th -- with 3.08 gears!

From reading other threads/posts, I think you have to use an ECM & harness from a donor vehicle that has a manual trans if you're not going to use the electronically controlled trans. Otherwise it will throw all sorts of codes from not having input from the trans.
