manually shifting

[Anti-Ricer]

Just picked up project redheaded stepchild from my friends house.he installed the 3.73 gears in it.anyways this is only the 2nd time I drove it since I got it and the longest im drove it. I gotta say I'm not use to driving the old vehicles. Going down the interstate I had to keep turning the steering wheel back and forth to keep it straight plus I had to turn the a mile before the the wheels turned lol.the breaks we're just as bad you better start stopping a ways back or you are going thru whatever is in front of you.now the engine is a 2004 350 vortec from a boat.The transmission is a turbo 350 with as everyone knows is a 3 spd no over drive now remember I just got gears installed. going down the interstate it feels like I should have 2 more gears. I bet if the truck with a 4 speed I could lift the front wheels lol.the truck was moaning and groaning like a torque monster. I do have one simple question the trans has B&M ratchet shifter which I always manually shift it.now here's my question is it bad to manually shift the transmission? And here is the order of it.
P .N. http://www.hotrodders.com/forum/manu...ml#post1705954 . 3. 2. 1 now where is [D]rive at and can I put it in drive if it has it or do I have to continue to manually shift it?
