Newbie here starting my first A body

Edelbrock Performer is a 318 intake with meat to hog out to 360 ports. Cheap, $100 used. 318 Streetmaster, LD4B, 273 4bbl iron, probably one or 2 more. All for around $100 used. 273 IS a 318 with smaller bores, thats it. Everything else is the same so all 318 parts short of pistons will fit your 273 and vice versa. 67-69 Darts, my favorite! Cheap headers, room for a B/RB, nice lines, mega body parts. Welcome aboard!
