Well same here. And I just turned 41 on Saturday. But we could be telling Cole a 650 CFM carb and 3.25 gears and he wants 600hp.
For a strong daily driver consider this. For a Windsor, you can do 9.5:1 compression with 224/232 @ .050 cam,Edelbrock heads and their RPM performer intake, 650cfm carb and headers and end up with 400hp at around 5500RPM.
If you carry this over to the Cleveland, I would expect at least this much power. I actually like the Air Gap intake and a 700-750 CFM carb. These two pieces will allow you to upgrade your setup if you like (more cam, stroker, etc).
As for gears, I think 3.50:1 are great for the street and fine for the freeway. Exhaust, I hate long tubes. They all seem to hang so low. Just my opinion.
