You don't need any Vasoline but you do need special motor mounts and exhaust to make it all fit.

That is the old set up with the huge 2.0" primary headers I used to have. They were too big and a pain to do anything with in the car. The new 440 that will be going in has the Schumacher 1 5/8" step up headers that are ceramic coated. They will even allow the car to have power steering put back on! (Very much needed with the weight of the 440 hanging out over the nose and the weight distribution of a FWD car!) She's been off the road for a number of years now but I want so badly to get it and my other projects running again. They will probably have to wait until after I'm married and into a new house. If I was going to start all over, I'd go with a huge stroker small block like a 408ci or 410ci or even the new 440 Super Commando crate motor. Big cubes and power but better packaging and less weight!
