Just looking for opinions on this. I am currently having a 400 built by a performance machine shop.

On several occasions I've said to the guy at the shop that I'd like to get AT LEAST 400 HP to the wheels. Up to this point his only response has been "We'll get you at least that much".

Well, long story short, I finally cornered him on the topic. His reply has me both happy and worried at the same time.

I personally only expected maybe 420 HP and 450 ft lbs of TQ on the dyno. He's telling me I'll be closer to 500 HP at the fly with at least 450 TQ!!!!

What kind of drive train will I need to support this??? I think I'm in a league I didn't intend to be in when I started all this.

I have SFC's (that I still need to install), and I think my trans will hold up OK, but what about a clutch?? I only have a stock one in it now. I also still have a one-legger alum. drum rear in it too. But am I beyond the level for a 10 bolt posi?? A 9 bolt??

Or will I need to drop even more big $$$ on a 12 bolt?? How about the factory torque arm?? Should I buy LCA relocation brackets??

I want to put the power to the ground, but how much will that cost? It's not like I have'nt spent enough already...

I know a lot of people that would love to have this problem, but they may think differently if they just spent over 4K on an engine, and face spending who knows how much more $$$ in order to use the engine without tearing up the rest of the car.

You'd think I would have figured all this out by now.

 

Sorry, I just realized that this should probably be on the Trans & drivetrain board.....
