Joel,I cant tell you the in's and outs of installing a 400 in an x frame car,but i'm sure there are people here that can.At about 450 hp,on a stock stroked 409,I'd suggest a convertor with a stall speed of around 3000 rpm for street/strip use,if it's a stroker,about 25oo should do you fine.Set the floor shifter up in the place where the original shifter comes thru the floor,have the transmission governor up to full-throttle shifts at 6000 rpm,put it in drive and GO!Yes,I'd definately keep all the original pieces for later re-installation.Another option would be to use a "switch-pitch convertor type 400 which will allow you to cruise around with a tighter 1500 stall,then when at the track,flip the switch and have a 300-3500 convertor for fun.
Charlie K will tell you the same as me. Both of us ran 4 speedd in the ole days, but got tired of breaking. You can make a 4-gear work, but lots of $$$ for clutch & trans....think $3k+, I suspect. Of course I'm talking about quite a bit of drag racing. Auto just so much more forgiving. 400 is stronger, but 350 will work, but still needs some good parts...ie:hardened sprag. If you're planning on 3:70 or 4:11 rear, w/ about 450 hp, I'd go w/ a TQ in the 2400 stall range. Short tires(slicks) will get you in low 12 second range, I'd guess & you could use tall street tires & still be pretty road worthy Now if your nickname is 409 Charlie & you're gonna try pro stock if they loosen the rules, you're gonna need to beef it up with good RR w/ spool & lots of other changes.

Thanks for all the good info. Still undecided but might stay with a 4 speed because of the budget. Bob Walla has one that he used & had it rebuilt. Said he never had any problems with it so that is good enough for me. Also since I will not be doing a lot of racing it should last, hopefully it will hold up & I won't destroy it.
Dave: Just noticed the dates on the shootout. How come so late this year? I usually attend yours & the West Coast (Aug 24& 25 this year). These dates will almost make it impossible for me to attend both. I realize that this most likely won't affect anyone else, is there any chance of it being changed back to the first weekend in August as in the past? Thanks.
Joel
Dave: Don't change it just for me. You need to be there. Go with whatever will be best for the group. Hope Reid is ok. Take care.
Joel
Might not have enough interest for a quorum anyhow.
Hi Joel , I had the driver's bucket seat altered to fit the Hurst shifter for my super T-10 4 speed. Turned out well and was not that expensive. This picture is with the TH350 trans.
