right now Ive got a MidWest 2800 to 3000 stall...it was behind my old 305..that got me a 1.7 60' with drag radials.....Im putting in a new motor that is a 383 HSR with a 226/232 cam

SHould I have the converter re-stalled? I called midwest and he told me that behind the 383 it will probalby flash to about 3200 or so....

what would should I do? I would rather do it now while the tranny is out of the car. THis will be a street car with limited time at the track..mostly street racin...

thanks!

3200 and street suck, less so if its a very tight converter like Vigilante's or Yank's.

I cant comment alot on the midwest since I no longer use anything other than vigilantes(I have my reason and they have proven themselves every single time in every app we have used them in, not something I can say about 3 other "wonder" brands)

If this is to be a street driven car 90+% of the time, I would get it restalled back a little lower like into the 24-2800 range, if its a tight converter.

If it tends to be a loose converter, might even back it down a tad more.

from what Midwest told me...its a tight converter...but behind my 305 it did just fine..acted just like normal..pulled when I tooked my foot off the brake and held itself even when I was on a slight hill...I could brkae stall it to about 2400 before the brakes would not hld it..but flashed to about 3000 when I mashed the gas...why would you say 3200 and street suck? I have read that I need a loose converter to get me in the powerr band of the cam...and get me good times.

Midwest says that being a tight converter it a 3200 or 3400 would do just fine on the street but that about pushin it...

please explain why you say it would be bad...

thanks

If you are keeping that 3.42 gear I'd stay with what you've got if it will stall about 3200. My 3500 yank and 3.73 gears is perfect, but with the 3.27 gear it was looser.

I wasted my time and money years ago with a 2200 stall and gave up alot on the street and track. Ended up switching it out for a 3500 stall anyway. I wouldn't buy anything lower than a 2800 even for a stock motor. You are giving up alot of et with the lower stall speeds.

It all depends on what you are used to. I wouldn't hesitate running a 4000 stall on the street now that I've run the 3500 for years, just too cheap to pull it back out and send it back.

yeah Im keeping the 3.42's I cant afford to get new gears. Im going to send the stall back to Midwest and have them go thru it and maybe restall it to about 3400......

so your saying I need the verter to be tight? I just want somthing that I can do good at the trck but Im putting this 383 together mainly for the streets around here.....Im wanna put most if not all the stangs to shame and some of the LS's around here tooo.

If you liked the manners of the 2800 convertor behind the 305 it will act the same behind the 383 during normal driving. Only when you floor it will the extra torque of the 383 cause the convetor to flash higher to 3200 RPM. Keep your original convertor if you were happy with the steet operation.

yeah I'll probably get it restallled to 3400...just to be sure....should I tell him to make it a tight converter or loose? Im thinking loose would be worse for the daily drivin.


my cam hits peak TQ at about 4000 and peak HP at about 5500
