Well I now have a useable 5.0 L block that I'm likely going to be stroking out to 331 cubes. However I want my drivetrain to hold up to this combo and be able to for the occasional use of 200-250 hp shots of NOS down the 1320. I have an SC with 199,000 km that I'm using for parts. I will be using the rear end as well and I'm wondering what I should do for drivetrain upgrades. I want to spend as little as possible with the ultimate goal being 500 hp for the car. Do I need to buy an aftermarket aluminum driveshaft or can I just have this one speed balanced or anything else? Where can I find an aluminum driveshaft? Also, what about the half shafts? What are my options there? If I need to look into aftermarket products, where should I look? Thanks for all the help
