Nothing but spinning tires
What's the secrete to planting the tires on a pick-up? After replacing a worn out 350 with a 450 hp 383 on a 68 short bed I noticed a lot of wheel spin, but it doesn't seem like it has that "bet you can't touch the dash" feeling. It's a GMC so it has a Dana 44 posi, and leaf spring rear end. It has 275x60 tires but it seems like even after letting up to get them to connect, a little more gas causes them to start spinning again. I would really like to see the truck run with the average 350 Camero's and Nova's running around. I should have quite a bit more power & torque, and the truck really doesn't weigh that much. (it's really not any bigger than an S-10) So, if it's not HP, what makes a fast truck. Is taller gearing in order? Is it just too heavy, or too light in the rear end?
