This reminds me of a great 305 V6 vs 350 v8 story a buddy of mine told me. He used to own a 65 GMC LWB C10 with a 305E/sm420 and 3.54 rear gear. He Loved that v6 and wouldn't have traded it for any v8.
Now here's the story:
He and a friend of his were ripping this deck down with their trucks.....his buddy had an early 70's or 80's Chevy 4x4 with a 350/th350. Well he backed up to the deck, and from what I remember hearing....in 1st gear that truck either couldn't spin the tires for it's life.....or they spun and the truck did nothing to that deck. Needless to say.....my buddy pulled up to the deck....hooked up...and in granny low, that v6 tore that deck apart without a thought.
And don't get me going on 305 v6 vs 305 v8 stories!
Never will Any chevy engine beat the durability and performance of the v6. Best engine GM ever made, not many can claim an easy 300,000 miles!
