    I probably wasn't clear in post #8 but I was talking about 2nd gear. I have 33's and I see you entered 31's using 3rd gear.

    I think my real world test is pretty close to the calculator. I played around with different rear gears, I like seeing the differences.

    Thanks for posting the calc link.

    That explains why you said "drop to 3rd". I definitely didn't catch what you meant. I entered 31" because generally tire diameters are less than their description says. Yours in reality are probably closer to 32" if you held a tape measure across one of them. 31 was a very conservative number on the lower side of course. :)

    Yeah, I understand very well about gearing and the gives and takes one deals with in going too low or too high. In another post I stated that my 280Z would actually go faster in 4th gear, redlined, than it would in 5th gear due to the things you mention above. Since I have 31" tires, it will be interesting to see how the combination works out. Hope the ratio isn't too tall. Do they make a blower for the F-134? OK, I am just kidding, but that would be interesting...

    I wanted to get the tranny back in my Jeep today, but it is my wife's birthday, so I would imagine that any work on the Jeep would be taboo. Maybe next weekend??

    I don't think I would want to be on the highway in my Jeep with a top end of 60 mph. That's not what I am building it for anyway, right? Thanks for the information.

    Been done - search. Some aspects of the F134 seem to favor forced induction - thick block, steel rods and crank. But it still is highly undersquare, which seems to go against the modern trend and is probably the single most significant issue limiting the power of the engine.

    That is one of the first things I noticed when I looked under the hood. The engine seems to be hugely tall in comparison to its width, side to side, and length, front to rear. One of my friends was with me, and I even remember him asking me what I meant when I stated, "That looks like an engine with a helluva stroke compared to what has to be a small bore". I even made the statement that the top hp numbers were probably 1/2 as large than the top torque numbers. Then after I found out the max rpm, since in general terms, rpm equals hp, it was interesting to see that I wasn't that far off as far as these numbers go.
