I did Dyno the motor but that didn't go well. But at 5100rpm it did make 776fpt and 754hp running sickly. So once we get her rite 900hp should be no problem. So how do y'all feel about me running a 833 4SD? 7563116-IMG_20120313_194345.jpg (139 downloads)

If you plan on "dead hooking" the tires, the trans may last a few passes, but will eventually break, if something else doesn't break first. What clutch are you planning on using? What rear are you planning on using? That kind of torq and HP will need a good clutch assembly and at least a Dana out back. 4 speed street legal. Best time 10.99 @ 124 mph on 93 octane pump gas @ 3926# total weight

If you plan on keeping it stick I would seriously be looking at a trans from liberty, jerico, or G-force...or step up to a nice Lenco and never worry at all again

As the input shaft and output shaft come together at the third gear it is a week point in the transmission. The pressure will push the gears apart and destroy the main third gear and cluster gear if not more. Ask me how I know that with a lot less horse power. Liberty Gears told me that would happen, took me 3 times to figure out. Spend a little more on a good transmission now and you will be $$$ ahead. it's ok to butt heads, just don't do it with a butthead

Massive amounts of power will require race type gearboxes and a GOOD clutch Sure its only a street car that will see the strip "sometimes", but all it takes one pass to have an expensive mess of parts at the power levels he is at

Of course now 650 of your 900 horses are just there for making tire smoke. Would a Richmond 5 spd even come close to hooking that up? It sounds to me like you will be in the 800 ft/lb range when you get it tuned and torque is the great destroyer of drive train parts. Kevin

Now here the kicker so don't laugh, I was going to use the od 4sd on the street and the regular 4sd which I was going to let Liberty face plate and use a v-gate shifter at the track.

(sorry had to laugh) I know a guy that runs an 833OD in his Hemi RR with no troubles BUT he doesn't beat on it and by that I mean no drag strip launches or power shifts and OD is for cruise ONLY. He runs it up to whatever in 3rd and holds it there in OD. If he needs to accelerate from like 60 to 80 it's back to 3rd to do it. He has driven it from Canada to Florida several times. Your right foot will ultimately determine how long less than ideal parts will last. Kevin

There are ups and downs to each setup but the Lenco is by far the best bet for low maintenance. I am in a similar boat (the 150 less hp than you boat that is) and have been making lots of inquiries lately.

Show us some pics after the 833 OD splits the case in half...seriously - w/o bushing those cases for the countershaft (if its aluminum) you ain't got a chance of that thing living, 318's and slant sixes can kill an OD 833...
