Slant six or v8 swap for use in a truck

lud said
I love the slant and the uniqueness, it also just makes my truck seem more ratty (which is what I'm going for) I have p235 75 r15 tires on my truck, and a A833OD with a 3.23 rear end. I can't remember what it is, I think a 9 1/4 axle. But the sound of a v8 can't be replaced, the power can't either but how much power do I really need. I've made up my mind I think tho, to keep the slant. It's an amazing engine that's already in it, has low miles, runs amazing and starts evertime. I've been around it in and out. I like the idea to mill the head and change the valves, but first I'm going to mess with the electrical bits and the timing.

That's an 8.25" rear as stated above. Putting the larger tires on was the equivalent of putting a 2.99:1 gearset in it, and the OD top gear is the combined equivalent of adding 2.18:1 cogs out back, good grief what do you expect from that poor Slanty!! I'd toss the 3.73's in it, the new comparative final drive ratio'd be 2.52:1, if that's important to You. Personally I dislike the OD 4spd, but if I wanted to use it in Your application, I'd put 4.10's in it for a final comparative top gear of 2.77's & plenty of pulling torque to get going...and easy on the clutch.
