Another small block turbo early valiant

eventually it will get a HDK front end. My first goal is to get it back on the road and enjoy it a little. I haven’t been behind the wheel for way too long. Lol. Just a suggestion, twins would probably be easier to pull off.

Can you tell me why so on the Twins, is it the plumbing?
After talking with someone else recently they had me leaning towards a Single PT88 and says the "Precisions have a smaller footprint".
