[QUOTE="Lil' Blue Rude, post: 368239, member: 4627"] If you wanna go fast I'm your guy. lol :mrgreen: Last time I checked on a 16' 48" Blazer ss they were around $2500. Your 75hp isn't going to pull a 7 3/16, sorry just not gonna happen. You've probably got the 49 cube block since it's 75hp, if you have the 56 cube block you can get it built up to pull the 7 3/16 impeller but your better of just getting a 6 7/8 stainless 3 blade. The 49 cube is better for high rpm the 56 is better for low end torque. jets need low end torque. It's hard to get back the low end torque with a 49 cube because of the port lay out on them. You can put a 56 cube powerhead on your current mid section, just have to swap out the exhaust and the drive shaft or put the 49 crank in the 56 cube block. [/QUOTE]
