Stock th350, no mods at all, have a 2400 stall on my bench, not sure I want to waste it on this trans.

 

I'd want a 2400 to 2800 rpm stall converter.

DO MA NEU!

 

That's why I bought it... But it's was for a new trans, that just isn't happening now, or at least until oil is @ $75/bbl.

Question of the day is, once I install it, it becomes used, and probably not recommended for use with a new trans => wasted cash. Or run it stock and hope for the best - if no good, could always just install it at that time. Engine is out at this time, would be pretty easy install, I'm off all this week, gotta say I'm putting my engine between the rails. But will have too wait 3 months before I can realistically try it out

 

I feel ya with lift Cost and and all.

DO MA NEU!

 

Oil patch is cut back pretty hard here...

Been fooling with my advace curve some more today, with relatively no success, swapped back to factory plugs, old dizzy cap and rotor, out to lunch now with my pit crew

 

I would stay with the 1800-2000rpm stall converter that comes with the c3 trans.

I suggest this since (before I took a walk on the wild side), I rebuild my engine in 1999 with a somewhat slippery TH350C. The C3 launched much HARD with the rebuild (I mean, it didn't just 'chirp' the tires anymore) off the line. It still had a tendency to slip under acceleration around 40mph which kept me from really enjoying the experience.

It wasn't until I stepped up to the 700R4 and 3.54 gears that it smoked the tires off the line (my 700R4 had same stock stall in range of 1800-2000rpm) and BARKED the tires going into 2nd.

If I were to refresh an L48/L82 engine, I would keep the stock stall converter... even if I were to step up bigger trans and diff ratios. The C3 converter is right in the 'sweet spot' (IMO) before you really need to change it (ie. to compliment a cam that requires "more than stock"). I've endeavored to keep my cam in that 'range' of performance that fits a stock converter... lots of fun to be had

 

I've got an hour or so to decide... Lol, just ran it up a few more time, pretty satisfied with the timing curve. Ended up ditching Mallory dist cap and button, something was amiss there, reused cap and button from car. 2 heaviest springs in mr mr gasket kit, all in at 2800.

Kinda rallied myself into the Thot process, if I can buy a tranny down the road I'll spring for another converter at that time...

Not sure, will decide later today when I swap engines on the hoist and stand. But Im goin for it tonite.

 

 

With the cam you are running you need at least 2400 stall.A 3000 stall would be even better with a built transmission.If your transmission is still in decent shape you should be fine.Maybe add a secondary cooler if you are worried about heat.They now make very efficient high stall converters that do not have the negative heat issues with them.What brand of converter do you have?

 

I don't think you'll need much stall - just the aftermarket one you have now, but not the stock one either. If it's rating is based on a 350 ci engine then we know it will be higher for your 400
Go for it !

(how's that for ten different opinions on stall speeds ?)

 

I left original tork in...can always undo it at a later date

 

Not bad for a cpl hrs, wouldn't fit with fan, had to pull it, got it in with alt and starter on, but in the end had to pull both to get headers in

Motor mounts on, tq bolted up, bellhousing tight, starter back on...

Calling it a nite

 

The higher The CI the lower a given cams operating range. The higher the CI the higher the bottom end torque. Convertor will probably be fine.

 

I'm hoping so, went ahead with stock to start, I still have it on the shelf if I need it, if I don't need it, I still have it when time comes for new trans.

Got the header gaskets on there and mounted up headers today, that's it.

Still got 3 months or so before driving season, but I'm gonna keep picking, even if all I have to look forward to is roasting tires in the garage

Notice the pool of red under the car... Managed to yank the trans dipstick outta it's hole and pinched it right off, trying to tip engine sideways to get headers in... Live & learn I guess.

 

Let me say, the other night when I dropped that engine in, I was on a high, it was awesome....

Then, reality, 1 whole evening spent installing headers properly... I hope

1 whole evening reinstalling a/c unit that may or may not even work, but without that belt on I could never stop the fan from squealing

After finishing up a/c realize fuel pump is hitting the frame, quit for night, went to bed with nightmares of pulling engine out of car

1 full evening removing/ installing fuel pump, no success, realigned bottom 4 times, no luck, quit for night, quite disenchanted.

Another full evening spent last 2 try's at realigning, got a spot to work, install fittings, run hose, oh man, what a battle to get the right amount of hose to allow it to not kink, and not so long to droop down to far. Install power steering hoses, and rad hoses. Pretty frustrating too spend a week of evenings, to realistically be no further ahead,

Next battle, somehow intertwined trans cooler lines into the header, in a manner that I'm not sure I could have done if I did it on purpose... I just hope the header won't have to come off.

Lost count of how many times I've layed on my creeper, and then promptly bashed my head into the sharp corner of wheel dolly...ugh
My hands and arms look like I've been strangling cats in my spare time.. Taking a day or too off from garage, starting to feel like my creeper is gonna get more miles on it than my car

 

Been picking away again

Spent an evening removing trans lines, and untangling trans line from headers, also changed out dipstick in trans, had to get wife to help me there... Actually 2nd trans dipstick tube on this car since I bought it

Got all the vacuum hoses on car hooked back up, swapped over all linkages on carb from old one, plugs, wires, are in, jumped up 2 heat ranges on plugs, (had some on my shelf) another experiment. Valve covers back on...

Just need to drop in battery, hook up starter wires, permanent install on side pipe tubes, fan & fan belts, getting close now!

 

I just drove my car

Wicked! Can't even say how awesome that just felt!

 

Tell us more!

 

Well, that's about. It really, it's still full on winter here.. So I only went about 2 miles up the road and back. Probably shoulda went with the stall converter, lugs it right down when u put it in gear, but really it has no trouble revving up tho, seems to have tons of power... Don't have a summer day to test it out on, but the way it planted me in the seat was awesome. Will have to wear earplugs to ride in it... Wonderfully loud!

I'm impressed
