Close ratio is the right ratio Mario! My under-powered gen 1 SBC with a 3.42 and T56 Mag close ratio is great. No problem with the taller 1st gear and it feels gap-less through the gears, 5-6 is the most noticeable and it's not bad. 1st gear is actually useable. I had a wide ratio in a '93 1LE Camaro and the low first gear typically created a situation of get it rolling and into 2nd asap to get business done.
I think you'll be very pleased.
