4.11 gear with a 4 spd already has "low speed torque" due to the engine revving so high. That combo needs an engine that makes power in the upper rpms (unless it is going into a tow truck).
what he really needs in a set of headers to make that mid rpm torque!!!
a 292H makes a nice "weekend" street cam. I have used that cam as just that and loved it. He isn't building a daily driver.
I have near that 350 setup with a 3.90 gear with a 5 spd in a 2800 pound car with 200cc darts. 1st gear is all torque and traction is very bad on street tires. Thankfully the engine pulls to 7200 rpm which gives 1st gear some pull at the end of the rpms when the tires stop spinning in the 6000 rpm range. With a smaller cam, 1st gear isn't usable, well maybe for a parking lot. Even with the 292H, I take off in 2nd gear most times.
the 292H is back to making torque at 3000 rpms which would be around 20mph in first gear (4.11 gear, 2.75 first gear, 26 inch tire).
