What to do ....'71 Longhorn?

[Sam Longhorn]

Hi All ...first post here ...

Details:
- '71 Longhorn ...90% restored
-350 (original?) with 200-R4
-odometer reads 89K
-Red Oak bed with SS
-Gas tank under bed
-non a/c
-truck located in Vancouver, BC (Fraser Valley ....rain forest!!!)

I am seriously considering turning it into a daily driver. Below are some considerations:

-remove the red oak and replace with white oak. White oak is superior to red oak for outdoor use
-could get cover but 100% water tight seal not possible & 3x more $$$
-keep 350 or swap with L4Q (6.0L) and current tranny ...I have the L4Q

I have debated the above for a number of years but am at a point where I have to pee or get off the pot ....I've moved and don't have room for three trucks ....the Longhorn, 2000 Silverado (L4Q donor) and a Honda Ridgeline, and yes the Ridgeline is a truck ....well, okay, ....truck...ish

Pro's .... Con's?
Thanks for any responses.
