I will soon be getting a job that will enable me to purchase a daily driver. The money pit will be retired to weekend cruising & racing. Since driveability will be even less of a concern, (not that it's much of one now) I will be doing a stroker, most likely a Keith Craft 331. I will be pushing the limits of a stock block, and I will need a tranny to take it.Now the question is, which tranny? Should I keep my manual setup and get a TKO 2, Jerico, etc? Or should I get a Lentech AOD or something similar? Either way I go, there will be issues. Like picking a stall for an auto, or clutch for a manual. Since I would be driving it to the strip, which is like a 30 minute highway drive, I'd prefer something with OD (sorry Alex, no JPT C-4). Lemme know what you think! ------------------

You've got an awfully stout driveline the way it is. Unless you plan on adding nitrous AND launching on slicks with the nitrous system ON, I'd just swap engines and be happy. You'll be fine.However, you'll want to upgrade to a better set of headers... possibly some Hooker Super Comps. Good Luck! ------------------

No forced induction, gonna stay N/A. Jet-Hot Super Comps are already planned!  I just want to make sure I don't blow up a tranny. Like I said, I am going to be pushing as much hp as I can, while trying to keep it under 7k rpms. So with the heads ported to match a custom cam, with 331 cubic inches, it should put out some nasty hp!

Just be wary of heads with raised exhaust ports... Header fitment can be an issue.Good Luck! ------------------

I think I am just gonna have my GT-40 X303 heads ported/milled instead of buying new ones.

After looking at your signature package and track results of [email protected] w/ a 1.837 60', I've got to ask, What are you running for tires at the track? ...Seems to me like only adding 4-into-1 headers and 9" ET Streets to your current package would put your 60'er's at the low 1.7's and 13.0's or even into the 12's at the big end........?

I currently have 26x8.5 ET Drags. However, I have not figured out the best launch rpm OR the best shift point(s), so there may be more left in the current combo.

I don't know what rods they put in your "XB3 Longblock", the condition of your clutch, Tremec trans or U-joints, but if they'll take 6500rpms, I'd consider launching at 5800 and shifting at 6200 rpms... Yep, it seems like alot the first time you do it, but you and your car will "LIKE IT A WHOLE BUNCH!".... Ryan

The only thing I don't know about is the rods/rod bolts. Everything else is in great shape, maybe a little more than 1 year old.

even a stock 5.0 shortblock is good past 6200 (hoping they are since i've revved the Ranger 6500 a few times!)  A Lentech costs money like a Lenco ...something to go with Lens? I've seen guys run 9's with that same Tremec you have,the first gear is a bit too low, should be more like 3.10 but it's not gonna slow you down much. The car should be capable of 1.4 second 60fts with tires that still fit in the wheelwells,like 9 x 28's.

As far as switching to a tranny, namely to a TKOII you won't gain a great deal more strength.
As you know, I have done ALOT of research on the Tremecs and the only differance from the TKO from the 3550 is the input and output shaft size and spline count. The differance in strength is 10-15% Not much a differance, but when it comes to marketing it does matter I guess. As for the TKOII from the TKO you probably know the fith gear ratio is lower. The fith gear is part of the main shaft and not seperate like the T5.
It is possible to upgrade your current 3550 to a TKOII level so you wouldn't need to buy a whole trans, just the input shaft and the main shaft.My opinion is you will be fine with what you have and your current plans.
