The one important factor that I see so many people ignore when chasing the big HP numbers is beefing up the rest of the drivetrain to support it. Reliable, big power costs. Applying said power to the pavement efficiently costs even more.
I hear ya man. I'm 34 now, but bought my Cutlass at 17 and it has been through a whirlwind of changes over the years.I definitely try to do my research, especially when it comes to building a new motor. Just looking for some more info and a good place to start so I can begin researching on a specific motor And start gathering parts over winter. I don’t like to do things twice, I’m 26 i already did that the first time I restored this car!
I had my body mounts replace about 500 miles ago with rubber mounts, I wish I would have went poly.Something to be careful about with the aluminum block LS motors is that they usually can only be rebored .010, plus the aluminum blocks flex and distort more under load than iron blocks. Its why trucks got iron blocks.
500 hp is a lot of stress on the g body structure and you will need frame and body reinforcing at 400 hp or above. Make sure your body mounts are good and no rust damage.

I have adjustable uppers and lower on the rear, big front sway bar, with Grand Prix bar and jounce bars. I have Grand National rear seat bracing with a rear sway bar and the rear frame horns tied. I also have fender to core support bars and firewall to core support bars. My car is very solid and handles great. I also have radiator cross bars, aftermarket transmission crossmember.
Do you think I will still need extra chassis reinforcement?
Yeah I know my turbo 350 won’t hold up to long. I have about $1500 in my rear end and I’m hoping that that holds up once I add new moser 28 spline axels. Fully adjustable suspension and I have a set of mickey Thompson drag radials on the rear. I plan on spending around 1500-2k on a transmission.The one important factor that I see so many people ignore when chasing the big HP numbers is beefing up the rest of the drivetrain to support it.

Yeah I custom fabbed up a grand national brace and am about to place my order for a rear shock tower brace from umi. You think my chassis should be able to support the power with all of those bolt ons? Frame is in good shape tooI think you'll be fine with that set up. Good body mounts are usually the most often overlooked. The GN bracing and shock tower bar also makes a big difference.
