just out of thin air a 4,000 9.5"TC are you having your TC rebuilt?... try to measure the cam lift and installed CL over the winter.that will help.

with my .509 hyd cam i know i wanted more than the 3,000 TC i had.there hyd cams going to the .550 lift range so it is a guessing game.a TC can be strong down low and still have 4K stall.what size tires do you have? an easy thing to check is if you have stock steel stamped valve train[rockers]not rollers.

Being that you are new to Mopars don't buy a TCI, Hughes, Art Carr or any used or any of the other cheaper brand converters. Go with a Turbo Action, Dynamicss, ATI, or one of the other ones that the guys on here will recommend that is custom built for your car A good converter is like a really good woman, hard to find, is really good to you and a real keeper

Turbo Action But you really need to know what you have in the engine.A lot of converters get installed based on "I know this is what I have" and then the converter company gets blamed when the combo is a dog.
Nautilus Racing- We use Superformance gaskets and Turbo Action converters/products.

Strokers are pretty forgiving if the converter is a bit tight...unlike say a 340 would be....torque is grunt and you need a heck of a lot of cam to take the bottom end grunt out of a 500" mopar. A 750 on a Stroker will start to choke off power above ~4800RPM but it will be very responsive and should add torque to the low end...going to a larger carb (~950-1000HP) will help the top end power with no real downside off idle-up. That said you say "the biggest Hydraulic they make"....well the biggest off the shelf Comp and Crane Hydrauic rollers are IIRC around 242 to [Email]248@.050....but[/Email] for example the Biggest Hughes is around 272 @.050 so there's a HUGE disparity between MFGs. My Find out more about what's inside what you just bought....then figure your wieght, gearing, tire size and how you intend to drive it and take that fto a reputable Converter MFG. do it once, do it right. As for off the shelf, I know from my own experience that a 'Tight' T/A 10" converter that Footbrake stalled around 3200 behind a 10:1 440 would stall around 3800-4000 behind one of my 265 @.050 solid cammed 500 motors, but it would feel very nice (no slushiness) at part throttle behind so much torque so it's a good default stroker vert for street occasional strip duty so long as you cooled it down between rounds. For an every week-end bracket type use I'd go to a more race-oriented unit. As a rule of thumb I try to get the stall pretty close t othe 70MPH highway cruise RPM....if you don't your MPG is gonna suck so I tend to build them custom with a tighter FB stall (As much as I think the suspension can handle) but with a looser FLASH which should optimumly be at the cusp of peak WOT torque RPM.....my own custom 9 1/2" PTC fb stalls at ~3400 but flashes to 4400, works great with 700HP and 3.54 gears.....but I cam and tune my street motors for the broadest and highest average torque and let the heads and induction carry the HP/RPM. Guys will tell you you I 'need' 4200 stall and 5000 flash and if my car was a drag car running on slicks probably so...but since the motor was built to make at least 90% of it's peak torque from ~3400 to about 5700 it really doesn't matter as much in the sense that the broader (less peaky) the torque the less critical the Stall/flash is so long as you're in the right ballpark...that's why it's so important to know your cam specs and head flow to pick the right vert....that said it works so well I'm getting bored with driving an Automatic so I'm gonna go back to a stick and have some real fun!!!

I'd be curious as to what you really have. No reason to run a Victor intake on a 440 that sounds like it isn't that built. Especially with a small carb.
I want my fair share
