Default Drivability question

Been a while since Iv'e done much and lots of changes, good and bad.

But here's the question I'm asking myself -- how "drivable" would a 401 w/auto be in a 'glass Model A pickup?

I've wanted to build one since I was a sprout and now have means/time to do it. I love low-end torque (drove Poppin' Johnnies as a kid) so the BB GMC's appeal to me.

But how will my antique engine out of a "New Idea" harvester handle long road runs and city traffic? (Assuming I get the gearing/tire size/etc correct)

I'd love to have the old torque monster in my truck but if something goes wrong two states away it could be a problem.

So what's you experience in long-distance cruising?

Sounds like a fun project! You should have no worries about long distance cruising. I bought my '62 in the Phoenix, AZ, area and drove it home to Oregon. Then later I drove it to Jolly's in Utah and back. And I drove my Dad's '65 from Wichita to Oregon in 2014 with no problems at all. Treated right, these engines are pretty bullet-proof.

I'm sure you're aware that your 401 weighs about 900 pounds. So you'll need some hefty springs for the front end on your glass A.

Yeah, the weight is another consideration along with gas mileage.

But both can be managed. I bet the Big V-6's sound good chuckling along at half the revs of others!
