Putting a 273 in Old Red Val.

2 things....

1. Early A's use the same k member whether /6 or V8...just the mounts for the V8 are different. What you will have to locate is a V8 dropped center link, for V8 oil pan clearance.

2. No early A factory dual exhaust trans X-members were ever made, mostly because they never offered dual exhaust in an early A. The "Commando" single was the only performance setup available. I believe Layson's offers a modded one for using dual exhaust, or you can mod your current one yourself (just copy the driver's side).
