Ok, I'm borrowing and possibly buying a trailer for my firebird this weekend. Any thoughts on if my old GMC is going to be able to pull it to the local track and back?(roughly 1hr away some hills but nothing too steep) Here's what it is:

1984 GMC 1/2 ton longbox

TIRED old 305 w/th350 newly rebuilt by me last summer

2.73 gearset

It pulled a yard and a quarter worth of concrete last fall and wasn't too bad besides being a little sluggish uphill.
