I myself do not see a drawback to the IRS rear in the sand rockets really. Even if you use a Jaugier Diff like they often do its not much wider than a Mendeola so travel can be similair. Since the motors weight is being carried a bit more by the front the rear should have no trouble dealing with odd terrain with as much or nearly as much travel. Just my thoughts on it. Same for the Ford diffs and any others you might run acorss.
Whip,I know what your saying...Roundy roundin for almost 30 years...Hanging out in Dick Trickles pit as a 6 year old...My 327 will be running A 2 barrel, It's already got a race prepped cast iron intake on it...1997 second in season overall points.. set up...On a 305 cranked 350 I have access to a flow bench At Superior head service :P I know there is alot of power to be had...And it's cheap for me to do the machine work...Since I have to drive to visit Fabr anyway...Juice deliveryI'm not too worried about more power You forget I'm a gimp I don't need to get my eyeballs flattened, or the g-force on my body,This is more of a no dollar build...But really I'm just looking to building a totally NO BUDGET Buggy...Because so many people have no money but want to play...You are really putting out good feedback,I'll worry about swiping Fabr's drag motor after I get the travel numbers and get enough seat time in it to see If it's even feasible to have the damn thing
I always got a out of how everyone seems to get all worked up when you say anything about a straight axle, no budget build!! Everyone says just sell something and then you can drop a grand into blah blah blah. For some of us its not that easy. I love the idea of this build. Instead of spending this thread talking about the merits of independent rears and bike motors, lets talk about what SPEC is building. There are some of us who are in this exact same boat, and would like to see this happen EXACTLY how he's planning it. The drive train layout and components are picked. Lets see some help with how to make them work.Sorry if that came out like a rant, but to see 3 pages on a topic I'm excited to see happen go on about everything this build is not about is kinda irritating.As for the build, I would go with the Jeep rear, TH350 trans for the better ratio's and light weight, and the 350 for the better low end torque, as more time will be spent cruising along. I'd love to see a double triangulated 4 link rear built, they have excellent travel with no binding when set up properly. Plus, if you do it I can see it built!! I don't know how to build one personally (proper angles and such) and would love to see it done. For the driveshaft, to keep it EXTREMELY low buck, I've seen square driveshafts work, and they have the ability to extend to almost double their length. If driveshaft speed is kept relatively low, vibration should be kept at a minimum. If nothing else it'll get it moving until a proper driveshaft can be afforded!!Have you figured your steering? I would likely use the S10 steering box (I seen the S10 rear end suggestion, so I'm assuming you have the truck!) The reason behind that is that you can use the power steering pump and everything will hook up to the 350. Use a modified Pitman arm with 2 tie-rod holes and extenders to get the proper steering geometry.Wow, first post in a while! Guess I made up for missed time, lol
