question

(75 w100 318la) as I'm going forward with building my first vehicle ever, I'm finding of course, I know nothing. My factory manual trans has a crunchy second and I'd love to replace it before putting down lots of power. I'd really love to keep it manual. Do you guys know any trans I can put it...

I believe my truck has the factory clutch, I'm sure you can understand my thoughts. All i can find though are ultra mega super duper grip grab grop clutches for drag cars with the 318. however that's not the only thing, I have never bought a clutch before and want something that can work well...
