look at the picture when I post.reread my post about using a bigger cam in a small block with 3.50 gears.
At 60 mph my tach reads 2k,if I want to accelerate i step on the gas.The torque is great.My bigger cam makes peak power at 6470 on the dyno.I use a 950 cfm HP holley.
If you put 4.11 gears in that car with that engine it will be like a bee on its back.
I use a TKO 600 5 speed.Its strong and has a 2.78 first gear. I dont like the way it shifts from second to third,not a big issue for me as I dont drag race
remember 2,000 rpm at 60 mph and my duration is 256/264,and I accelerate smoothly and easily from there even in 5th
