I'll be building this from the ground up. new push rods, rockers, everything. This will ultimately replace the wimpy 305 in my car (86 Trans Am) now. Has anyone here built one of these combinations before? If so, just what exactly could it do?
I figured something like this would be up a hotrodder's alley, so I was hoping I could find out even more information here. Thanks in advance folks!

I don't see the advantage. The L99 crank will bolt into the early 350 block, but usually if someone does something like this, there will be an advantage in rev range or higher static compression ratio running better fuel in a race configuration. But in this case, the crank is cast, so there is no rev advantage and the currently available pump fuel quality will not allow much over 10.0:1 static compression ratio due to detonation, so it looks to me like you'd be throwing good money after bad just to say that you have a 302 in the car. If your goal is to improve performance in that 3500 lb car, bolt a 383 kit into your 350 block, along with a set of 195cc Pro-Filer heads, Edelbrock Performer RPM intake, 750 carb, 1 3/4" equal length headers. You'll make 500 hp, 500 foot pounds of torque and life is good, and you can tell everyone it's a 302.

Here's a link to using the 3" crank though, if you're just hard-headed....
