I am doing a very similar redo of my 78 --3.4 95 Camaro engine, carb & distributor. I have the following question. Did you use the stock 3.9 rear end and if so what gearing do you have in the trans? The 2.95 V8 or the V6. From everything I have read it seems if you keep the stock rear you should use the V8 trans. Your thoughts?

Love the conversion. Doing the same to my '78, 3.4 V6, crate engine no longer available. Question, are you using a Mustang trans? I have both a Camaro and a 2000 Mustang. Are you using the stock rear axle with the 3.90 ratio. My paint and body work is done but taking a long time to finish the project. email me at thanks, jim

This car could make me give up the idea of getting a Miata. Beautiful restoration... actually if MG had built a car like this they might still be in business... Still for sale???

Yea... on second thought it is a 10...I had a little issue with the wheels but that is purely a matter of persona taste... the car is friggen awesome! If i had a three car garage I'dd buy this... you have sunk some serious do-ray-mi into it.
