You know guys it is a personal choice. If you like it, want it, then go for it! Being a farm boy I could take the old IH 4 cylinders and get better HP. Driving a 235 in my teens I could make it bark! There is always more horsepower and performance you can get from all most engines! Today at 68 yrs. old I still love HP. My 59 came with a 350 the motor was junk, today I have installed a made into 383 why; because I can it makes me happy! Last Sat. at a car show downtown Lagro, In. I saw a 61 Chevy stepside with a 283 3 deuces impressed me a whole lot! life has taught me go for it!
