On Thunders site, a TREX cam requires a 4000+ stall. Now, what stall at around 4000 can handle a 100 wet shot? I have to keep my stock heads(I have a screwed up thread hole where the back head bolt goes in, so I don't want to risk taking the heads off and getting aftermarket ones). My goal is to hit at least high 10s(I've already dropped 150 lbs).

Or would I get better times by just getting the 4400 and doing it cam-only? I heard the Yank series (pt?) at a 4000 stall can handle a shot of nitrous like that, but won't the shift extension get up too high?

What do you all suggest?

Call a converter company of your choice and ask them what they recommend. I think a 4000 stall would be about right, have you considered having you SSF3500 restalled to 4000? That's what I did with mine after going large with cam selection, cost me $125 plus shipping. How high do you plan to spin the motor?

Edit: Oh yeah, that will be rough on the bottom end. I am only spinning my motor to 6500 and wouldn't go over 6800 even on a newer year, just personal pref. I also plan to add heads and N20 later, but the nitrous won't be until AFTER I forge the bottom end.

That's gonna be pretty rough on a stock shortblock, 7000 + rpms and N2O. I'd put the car on a diet, and go with 4400 stall or so. But don't let me scare you off, my setup isn't too different than yours, but I'm hoping that the N2O will bring my power down a few hundred rpms and I''ll be shifting at 6500 or so. I think the best results with the T-rex have been had shifting it at around 7200 rpms. I know that there are people spraying on a TCI4000 so restalling is an option.

souns like a good suggestiong, but if u restall a 3500-4000 want that be just like getting the 4000 cheaper? lol im persoanlly debating this myself.. and have searched and read that if ur spraying more then 150 or 100 with a big cam u better just get a converter with a anti ballooning plate ect.. i reccomend a restall or a yank ss 3600 or 4000 converter.. the 4000 i would do for the trex ofcourse

Contact kevin winsted (sp?) at TCI. I'm sure you can get your current converter rebuilt to handle what you are looking for.

ss4000e for Trex and n20 would be nice....

I think for insurance purposes I'll add some ARP rod-bolts. If that thread becomes too troublesome, I guess I can always have it heli-coiled. Looks like this can be a very doable combo. a moser 12 bolt with 4.10s will complement this as well.

hmm... wonder how long the t-rex with a ss4000e and 150 shot would last on the stock bottom end.. trex doens't look like a very nitrous friendly cam? or is it?

It's going to be hard to maximize both efforts. I would keep the 3500 stall if you're wanting to really spray it, if not I'd look at a bit looser converter.
