Personally, I would stay with the 4 speed, unless you want to spend money, which you said you would like to stay budget friendly. Passon Performance has an overdrive gear set that looks awesome, but I haven’t found any one who has used one so no real info on how they like it. If you don’t mind the gap in the gear ratio, the overdrive 4 speed is a great alternative to the pricey standard 4 speeds. I have been building 4 speeds for years and from experience I would recommend a cast iron cased OD if you go that route they only made them a couple years, but the iron case is the way to go. I actually have one on the stand I’m building right now that will be available soon. As far as pedals, there pricey, but I don’t know of any alternative to factory pedals. This is a 4 speed I just finished. If you’re interested in the OD trans I have message me we can discuss price
