You might want to do some research on that first. I don't think I've ever seen a positive comment regarding Monster. A 4L80E would be a better choice, but that's not without its own set of complications with having to have a controller and whatnot.

That looks real nice! Great to see someone that pays attention to detail like myself!
Will a 4L80E fit in that GP without tunnel or firewall modifications? My car also has buckets, console and floor shift. Could that be a problem?
I’ve been told if the 700R 4 that’s in the car is built right, it can handle 500hp real well. The car is set up for a 700R4. The drive shaft has been sent out, sized and balanced. The trans crossmember has also been modified already.
It's the torque that will kill it, but as long as you don't put stickies on there, you could be fine.

Oh because I read the problem with the 700R4 is heat and torque. I can deal with the heat with a good cooler. I was told they can be built to take the punishment. I really don’t plan on constantly beating the piss out of this car when finished. But I do want it to be reliable when I do get on it. It will be driven on weekends to local car shows and around town.
I’m wondering about the rear end? I know for a fact that 10 bolt will blow apart in to time. I want to know the cheapest rout to a 12 bolt 373 or 410 for that car? I read there are no vehicles with a 12 bolt I can just bolt up to my car.
I’ve got a 200-r4 in mine, built of course 650 to the wheels now, no problems. I’m using the Grand National 8.5 which will bolt right up. They are known for the durability but you can have it built also.
I am in the process of having a shaker conversion with a hood tach done. I wanted a really good fabricator to make this look stock. I’m really excited about the results so far. Tell me what you guys think!
