To anyone that cares, someone is actually building a whole set of these and accompanying parts for sale at the performance years forum.

@pwkid the reproduction RA V heads won't run like the originals, the repop heads have much smaller ports

@qmimi1 yes a RA V engine has a sound all its own

did u have to build ur 350 trans to hold the power or just put in a better torque converter? im puttin a 455 im my TA and its got a th350 and im wondering if it'll hold the power?

@tunnelportterror Yah from what I read, smaller ports with equal or better airflow. That is pretty awesome.
