Engine/trans/rearend combo

[mygirlz55]

I 'm at the point in my build where things are starting to get installed, and want some opinions etc on my powertrain combination. I 'm working with what I already have so please be nice if this doesn't seem to be a good idea.
I've installed a 77 camaro front clip into our 55 TF and put the engine (305 v8) back in along with the 400 auto trans.
I have the rear end from the 77 camaro and it looks to be 2.41:1 ratio.
Does this sound like it would work as a good setup for our truck?
Don't plan on doing and major hauling etc. And I plan on doing a rear axle flip to lower the rear down to match the front end.
Thanks for your suggestions.
