I'm in the market for a torque converter. I don't know what my peak hp and tq numbers are or where they fall. I was hoping that maybe someone here could help me figure it out. Maybe someone with desktop dyno?

Here is the jist of my combo:
-383 w/flat top pistons (11.67-1 compression)
-Edelbrock 6085 heads (out of the box)
-zz9 camshaft w/1.6 rr's
(212/226@.050 .515/.525)
-Edelbrock TPI intake (out of the box)
-SLP runners
-Ported plenum
-52mm TB
-Stock 22lb injectors
-4.10 gears

Any help or even advice on picking the correct type of converter would be GREATLY appreciated. TPIS Said that "I'm making peak power at 4,500rpms and should stick to a stall speed of 2000-2400" Does this sound right?

Thanks
Bob

 

I just ran you engine on desktop dyno2000 and it says 409hp@5500 rpm and 450fp@4000 rpm.These numbers are goten from running the cam strait up. You can use these ratings as a guide and from experance they are pretty close.

sorry I forgot to enter your 383 and comp ratio

HP 430@4500
TQ 491@4000

 

if you can e-mail me the numbers on your cam card and I can try to nail it down more accuratly. I would like to get the no. off the cam card for my own files anyway.

 

Thanks!!! Let me dig out my card.... I'll post the specs in a few

 

Here are the numbers as they appear on the card:

Duration at .050 -- 212/226
Lobe Lift -- .3229/.3466
Lobe Separation -- 112*

Seat Duration -- 270/282
Gross Valve Lift -- .484/.520 (1.6=.515/.554)
Degree Intake Lobe -- 108 ATDC

Seat timing Int: 0 BTDC: 32 ABDC: 108
Seat timing Exh: 48 BBDC: 3 ATDC: 116

Thanks again for your help!!!!!

if you can recheck your camcard and make shure it is right I am coming out with some strange readings with the numbers you posted.

 

Ok, see if I can get this to work... Here's the card that came with the cam.

 

desktop dyno says that your motor will make 508tq @ 3500
428hp @ 5000
those numbers are running the cam at 3* advanced.

those are great numbers, but I would not take them to heart they are numbers from a computer not actual numbers you will actually produce.

Good luck
thats one hell of a engine.

 

Thanks for the help! Yeah I know those numbers are high but its a starting point Hey, could you save and email me the .dyn file for that? I got a copy of dd2000 today! My email is bobden13@erols.com

So far the engine has been in the car for a year now. The transmission has been a problem from the start so I haven't been able to really enjoy it. I got a new tranny under my warranty, but its "remanufactured to oem spec". I'm gonna get some extras for it as soon as my tax refund gets here
