68 Cuda Viper

The guys at magnum force race cars in Campbell ca. Might be able to steer you in the right direction. I was there a few weeks ago and they have done several viper engine installs in mainly E bodies. You have to relocate the hell out of the firewall to position the engine far back enough to get the weight distribution correct. The have installed one further forward in the standard position and they said it was terrible and scary to drive due to the nose heavy condition. You would have to do some serious cutting to get that to fit but it would be bad ***! It looked shoehorned into that E body cuda so an A would be tight. As far as tranny I'm thinking one out of a 3/4 ton pickup should work being that the v-10 blocks are similar but I'm not sure if tiny thing else would need to be changed to facilitate the stick to auto change. Give those guys a call, they are super cool and like to talk about mopars.
