i kno nothing and i mean nothing about this stall converter thing. i know nothing about what it is or does??
don;t wimp it down. Build it exactly as I layed out for you.
ya you want a high stall converter for a cammed up 307.

A stock torque converter will not work.
10" 3500 stall like the B&M #20425 or equal. (th-350) 4.10-4.56 gears.
The lil 307 wants to rev up. No the valves won;t hit with this cam or with the isky Z27 cam.
Get a qualified automotive machinist to help you with the cylinder head machining.
Its pretty straight forward basic stuff. Do the porting yourself first.
