What type of driving do you do with your cruiser? Highway will suck, period (with the 2F). You will be able to get it up to speed but keeping it there on any sort of a hill is problematical. Around town is not a big deal. Piece of cake actually. On the trail it all depends on what you are runnig for a transmission. With the 420 or a 465 you will not really notice it.
If you are running a V8 all bets are off. I have a buddy running a EB with a 351 warmed to 426 and he pulls hills very easily at highway speeds with 4.11's
Get the larger meats. Try it out and see how you like it. If it does not work for you get some 4.88's. Like Nolen said they are just as easily put in later down the road...
p.s. the problem with 36" tires is that they start looking small very quickly!!!!!
I have a stock F motor with 36's and 4:11's.
Its been this way for about 3 months. I am living with it now because I'll be putting in a V8, th350, and 4:88's soon. It works, but it's a dog. Way under powered and over geared. But hey do what you can afford a little at a time. Start with the tires and go from there. <IMG SRC="smilies/biggrin.gif" border="0">
i have 36's, w/ 4.11's, and a 350..its fine around town, but sucks on the freeway...before w/ the 33's, i'd cruise at 2200 rpm at approx. 70 mph (in overdrive w/ 700R4)...now its close to 1700 rpm in overdrive, so i dont drive in it, i leave it in 3rd gear and cruise at about 2800 rpm or so...im going to 4.88's so i can drive in overdrive once again. plus it'll up my crawl ratio!
i had a 5 speed and 35s and a four cylinder diesel, i got the turbo recon'd and then it could pull the 35s in fifth, but unitl i reco'ed it it was not a healthy boy in fifth with 35s! but up till fourth gear it was schweet! so i dont reckon 36s will give you probs right up till 4th gear!
I know several ppl running 4.11's and 36" swampers with their 2F engine. I know Mudrak (Gary Kardum at Mudrak Custom Cruisers) is running that set up in his FJ45. I followed him up to northern OR on a road trip to Tillamook (sp?) and he was scootin' right along at 75-80 on I5 and only lost speed when climbing over the summits (long, steep grades).
For a 350 powered TLC - no worries either. I am running 35's and the 4.11 gearing with no problem on the highway or in town. Works great on the trail.
I thought about going to 4.88's and stayed with 4.11's when I realized how easy it would be to get spare 4.11 parts ont he trail if I broke. Not near as many guys running 4.88's.
Give it a try and don't worry about it (yet). Just my $0.02
