hey shinrar...
depends what you want to use the car for??? track/drags/drift/road
i am currently to a sr20det motor into a 78 2dr, and as has already been mention go to
www.classicford.mine.nu you'll find everything there
I think the sr is a good conversion and motor is not to heavy parts are everywhere!! and not to much modifying...except engine mounts/trans tunnel and the usual stuff but easy to mod this engine with off the shelf parts.
