G'day all, I would agree with Rusty and Jim with regards to sticking with the stock engine, although I would still take approx 150 thou off the head to take the compression to around 7.25. With standard gearing of 4.54, a 38 Six is doing over 3,000 rpm at 60 mph. I would be more concerned with getting a 4.1 rear end and getting the revs down. My 38 Six runs 2,200 rpm at 65mph with a 4.36 (120) rear end and an R6 O/D. But the standard motor will pull almost as well anyway, you will only feel the difference on the hills . Just soup it up a bit if you have to work on the engine for some reason. Best Regards Peter Toet.
