Reminds me of Marks Ol toy from WMS......looks good. I dam neer killed myself rolling the 52s arround, and the 49s wasnt that much fun either. I am still on the edge on weither to swap out the 302 for the 4bt in my buggy. I just dont think I will be happy with the get up and go because of the gearing, but I also run/jump alot at the dunes. What kind of wheelin are you mostly into? Flat/big rocks....rocky hillclimbs etc?
sounds like it would be a good swap for you then. I am worried about needing to get some wheel speed up and going, and only having half the rpm before having to shift. There have been quite a few times where im bangin the rev limeter at 6500 back and forth to make it up something. For true crawling though it will definatly be a torque monster, that would just lug its way through, or spin the tires, or break something if it got in a bind with that low of a ratio.....torque is a mother One thing to think about.. everybody will love it at camp, but after a couple of hours on the trail they might be wanting some ear plugs, and a rag to wipe the soot off of there windsheilds :grinpimp: nice to have ya here...later
The 4BT would be great for the rocks then. You've got some awesome gear reduction - not sure on your doubler but I'll assume 4:1 x 3.06 1st gear x 6.72 in the rockwells. 82.2528 crawl ratio. Add that to torque converter multiplication and you've got some massive torque. 4BT would rock for crawling compared to the 350. You've got an enclosed fuel injection system too on the 4BT which will help in the rocks. Not sure how wild you get but have you considered running a dry-sump system?
What gear ratios are in the axles and in the t-cases? What specifically are you not happy with the 350 about, or should I say what do you expect to get from the 4bt that the 350 can't give you.
BTW Nice truggy! :beer:
