Can you post a copy of your class rules. Or just give me a link to you track. As you know mud bogging is so different in every area.
Just because you out run a 434 with a smaller motor deosn't mean 434's aren't good. It's all about the total combo. Just think how much faster you would you if you had the bigger motor.
Motor wise and stock fuel pump some of you guys help me out on that part too.
The truck part I can help no problem.
4,300lbs is still to heavy for a full size truck with a small block.
You should be able to get in the 3,900lb or less range with a 200lb driver.
You have to run a trans that came in the truck? Can you run a trans brake?
I need to know what you can and can't do with the rear leaf springs.
How many springs do you have to have?
Can you run adjustable shocks?
Can you run coil over shocks?
