Looks like you got a good start going but there's a couple things the worry me.
1. The front nose cone mount will want to pull up with hard launches or acceleration and I'm worried the studs may pull out of the rubber bushing. Having the rear mounts attached to the motor instead of the bell housing move the fulcrum point and weaken the leverage but it's still worth considering.
2. The tranny and motor look like they are sitting back a bit so it might hit the body or you might have to cut the body for the engine to fit.
Aside from that you got any more info about the build? This thing will certain haul ass when your done.
