SBC 400 specs. will this be a good K5 engine?

If you run it and dont like it, too much stahl maybe, I am in Maryland, B-more, if your not too far away I have a couple tc that stahl lower, your welcome to try them out.

rootbreaker, how much was that desktop dyno software? what year is it?

I used a friends machine.... he bought it a while back... havent seen him in a while...... :crazy:
 
I don't wear panties...

and yes you sound like you are educated on your opinion... as are each of us... this is what we know and what we have to work with...


the converter you have will work... no one has said that it wouldn't do the job... depending on what you want to do with your truck, it may be perfect... some of us need the tranny to lock up early to pull heavy loads, some need it to lock up completely off idle to climb rocks, and yes, some guys run really high stalls in their mud trucks to keep the rpms up while they're trying to dig themselves into a bigger hole...

as far as general driveability, that stall sounds way too high for a general use tranny that most of us post about. at the same time, most of us stick with the 350s and 454s... run what you've got... when something breaks, that's the part you know you'll need to fix....
 
Thank you, thats all i was really after.

And to the others, im not saying you aren't educated. Just don't assume I am completely wrong and off my rocker b/c of what i posted. I'm not arguing with anyone on any topic just trying to give as much info as possible. As i said I have never built up a 4x only cars before. I don't want to hear "it won't work" and thats it. tell me why it won't work. if you have experience with it then that means you are more educated about it. not "i run this and my engine is similar to yours so you need to run this too"

and if my K5 came with a 350 or 454 then thats what i would have built but it came with a 400 and i just happened to have a 400 sitting there already built so i swapped them so i could work on the original 400.

but thanx for the replies and input. im sure i will be dropping that heavy a** 203 and 350 to swap converters again.... this isn't going to be a rock buggy or trail only rig. but by the sounds of things a lower stall will be better off.
 
Im running a 2500 stall conveter with my 400. For street driving it might be a little loose, but I have a decent sized cam so it allows it to idle a little better with out locking up.
 
I believe the stall rating is for the converter to flash up to that rpm when used for flat out racing (i.e. drags) I have a 2800 in my car and it'll move at idle with no problem, and I can take off normally without revving the engine to get it going. It will however allow more slippage at part throttle, than a stock converter. HP will affect the actual flash point also.
Try to advance the cam timing 4*(in relation to the crank). This should give you more low rpm torque and hp.
 
Finally had the K5 out for a test run. 76zimmer you are right on that. I can take off with little throttle and if I accelerate slowly you can fell it slipping (although some has gotta be tranny related b/c it is still low on fluid!) but punch the throttle and she giddie ups and goes.. think it still might be too much stall though. just hate the idea of pulling that 350 and 203 again by myself...

Your gonna hate that stall. Imagine, you will have to rev up to 3200 RPM to move that thing. It will suck in parking lots, driveways, slow moving on the trail. You will burn up the tranny when cruising at 2500 RPM. Better get a HUGE tranny cooler. I had a 2000RPM stall converter for a month in a "hot rod". It sucked!! My current 425-450HP 388 has a converter with only a couple hundred more RPM stall so it can idle at 800 RPM.

3200 rpm stall converter doesn't mean the motor is spinning 3200 rpm... its alot less. Don't remember how to calcuate tc stall but rpm of the motor is not it. I'm sure somebody on here will chime in and tell us how they calculate it.

I'm running a 2000-2400 stall tc on my 355...330 hp 400 ft lbs and that converter means it launches like a mother focker and is still low enough to deal with trails and not overheat.

I'd recommend a good tranny cooler just to be safe tho.
