Slant six or v8 swap for use in a truck

I have no idea if this is the right place to post this thread, but I have a beautiful 225 slant six I prettied up from a 63 Plymouth Belvedere shoved into my 1982 dodge d150. The engine only has around 80k miles on it, I got rid of the one barrel (holley model 1920) in exchange for a 2 barrel (carter Hightop bbd) which required changing the intake and exaust manifold. Easier said than done. But it's done did. There was this floppy thingy inside of the exaust manifold but it's not there anymore. Prolly some EGR save the planet stuff idk. This alone on top of a brand new clutch really increased the power. Like alot alot. I increased the tires from a p195 to a p235 so it needs geared from the 3.23 it's at. To a 3.55 or 3.73 maybe even a 4.11 ... sounds expensive. I can cruise and get up to speed pretty good, even with a quad in the back of the truck. Or about half a cord of wood. I dragged a camper out of the hole it sunk into from sitting aswell. I love the gas mileage that come with the engine and gear ratios involved. The question or rather discussion I want to have is whether or not it's worth going to a v8... the slant will never sound or perform like a v8 would, and the slant refuses to spin the tires and once your up to speed it has no power, it has a stick shift yet I can’t drop the clutch and let her eat... I got a cool truck that looks quick, sounds mean but ain't. It's got balls in 1st and second gear.. is it a gear problem, do I have to mill the head, mess with the spark make it happeners. Transmission? Cam it? 4 barrel? Bigger 2 barrel? Or would it just be cheaper and better to get a junk 318 that turns over and completely rebuild it. I should mention this trucks my daily. (Threw in a picture of the truck when I got it cuz im proud of it) I don't have any newer pictures with the 2 barrel on it , aswell as I was not able to upload any good pictures because this website doesn't allow for pictures of such quality. Be mindful of budget. Like let's say you only had $100 a week to spare on this. Any input is welcome
