Stop in for a cup of coffee

so you guys know early A stuff in here.

Would a slant six out of a 67 barracuda bolt right into an early Valiant with a 3 speed trans and all? using the rear end and driveshaft from the barracuda as well. Are the mounts the same? oil pan clearance ???

Didn't they change the diameter of the torque converter snout in 66??? You would need to match the converter and trans...

How are you going to shift the trans? The 63 is push button/cable shift, where 67 is linkages... You would need to work out the shifting...
