    I don't think a Lenco would bolt up, I could be wrong though

    Yeah, I'm not real sure how that'd work out. They probably do, or could, make one to handle the power though, especially considering what their standard use/purpose is. If one could be made to bolt up, it might actually be in-line cost wise with buying an Eaton or a set of boxes. Man, you almost have me excited over this 'project's now! Lol

    Myself I’d take a c12 over a c13 it has less issues even better yet a 12.7 series 60..

    If I could have found one, I'd have dropped an old 11.1 Series 60 in mine.

    Off topic but geeze I was like a half hour away from St Malo last week.

    I think I'm going to go with an Allison 4800 for this since it's rated for 680~800 horsepower and ~2,000 ft-lbs of torque. First gear looks really ####in steep but my next concern would be how I go about transfering power from the engine and to the rear wheels. I think I'm going to use a Quick Change center section for independent suspension setups but I'm unsure if I should go about getting a pair of flanges to directly couple the tranny output to the differential input or if I should go with a driveshaft, a short one at that. From there I think I'm going to go with Corvette style suspension and brake components since my original thought was to go with GM one ton wheel hubs and custom cv axles but seeing as how I can't find tires for 22.5" super single wheels with a low enough profile and a high enough speed rating to be practical

    You are expressing thoughts that are on a much higher plane of racing than I am, however do not think to put short wheels on a vehicle that needs to get down the distance with a given engine speed of rotation. Don't get too short wheels. You will just waste time with them.

    At some point wheel will spin at whatever rotational speed it can get maxed out, now with a tall enough tire you can gain more distance with less rotation count per mile.

    makes sense?

    To some who talked cars and times, I am not that good on the 1/4 mile, I can do it but it's not my best. I am mostly a top end man. And as such take great pleasure in having engines capable of staying at red line or a little beyond for extended periods of time. Brand or type does not matter as long I get it all out and keep it there.

    My thing with going with Corvette suspension and brake components is that with 22.5" super single wheels the only tires I'd seemingly be able to find are those meant for use on a truck as large as a Freightliner and I don't think I'd want to take the risk of running a tire that's rated for at most 70 or 80 miles per hour at more than double that, I haven't had a chance to look into the selection that's out there at the time of this post as I'm just getting done with another day of fighting with the fourteen hour rule and being restricted by California speed limits

    Another thing about that, tire selection is part of it but brake selection is another thing all of its own, with Corvette wheel hubs I can go with some top quality brakes like Wilwood or Baer carbon ceramics which, from what I know and not having first hand experience with them yet, are some #### nice brakes as the nature of carbon ceramics rotors doesn't allow brake fade, the carbon just sublimes off into one oxide or another, plus I can go with a hydraulic system instead of a pneumatic system which is imo an all around better option for this application because it means the vehicle can be smaller because I'm not having to leave enough clearance for comparitively massive brake drums and if I were feeling like having even more of a headache in the fluid management department I could go with a rear steer setup in addition to what will probably be a hydraulic rack and pinion system up front because I imagine this would be too heavy for an electric power steering system and manual power steering is all sorts of no from me

    I am reading this and wonder what is the project? Is this going to be a Blastoline kinda thing?

    Regarding transmissions, I was thinking about using an Allison behind a C13 in my Peterbilt. A friend that is an engineer at KW said it would be a daunting task. A lot of uncertainty in parts and support from Allison on older Cat engines and the new transmissions.. As far as manual transmissions, most heavy truck trans are non-syncro, Volvo has or had a 13 speed full syncro transmission in the early 90's, knew a guy with a truck that had one.

    As far as driveline components, IF you are going to use a C13 that is set to 470-500HP 1650/1750 torque one ton stuff is not up to the task. Not stock one ton stuff at least. The torque will tear up the gears/splines. Corvette stuff is going to be far to light to withstand the forces you are suggesting. The forgings are designed to withstand an upset force well below what you propose. If you just want to smoke the tires maybe you can get away with some of this stuff, if it hooks it will break. While the HP may not be as impressive as a hoped up 5.9 the torque of a 13 liter engine is double that of the smaller engine. Yea some of the driveline stuff is designed to haul 80-120K loads but, going from a SPL170 u-joint to 1350 or 1410 is like using a 1/4" extension to torque main caps.

    Can you elaborate on the design and configuration, you mention mid engine? Is this going to haul or tow anything?

    I'm not going to go with GM one ton equipment, I considered it at first because I found wheel adapters that would let me use super single wheels and I thought that would look pretty cool, however tire options killed that idea. As far as Corvette components they would not be stock, there are companies out there that make driveline components for high output racing applications, such as The Driveline Shop (yes that's their actual name, look them up) makes components for the Corvette that's rated for as high as 1,600 horsepower, plus they can make axles custom to pretty much any application. As for it being something like Blastolene I had never heard of it till this post and so I'm not familiar with it, the first image that came to mind in my head when I first seriously thought about it was something similar to the Ford GT40, albeit loosely. It's not going to tow or haul anything, I have other ideas as to what I would use for those purposes
