Torque converter recommendation

Post by ChevelleNut » Wed Mar 04, 2015 9:19 pm

I'm needing some help picking the right torque converter for my drag car. I'm hearing and reading different ways of choosing one. I'll give you my specs and see what y'all come up with.

1968 Chevelle
3250 lbs.
Foot brake
489 BBC - No power adders
Cam - Solid flat tappet, 262/265 @ .050 on a 112 lsa
690 HP @ 6500 / 642 ft lb @ 4500 (according to Desktop Dyno)
TH 400
4:11 gears
29-10 Drag slicks

Thanks in advance

I would talk to a custom converter builder and have one built specifically for your combo and purpose. A good converter builder will know what to ask to get you exactly what you want.

If you were to put a "3600 stall" off the shelf converter behind that 489CID engine you will see about a 4200 stall
at the track, on launch.
The converter is rated for stall speed when behind a 350cid engine. ( Most all off the shelf converters are rated for when behind a 350CID engine). Your 489 CID motor makes more torque so the stall will be higher. About 4200 rpm stall.
A good place to be.

EG B&M Holeshot 3600 #20425

if a bolt in off the shelf high stall converter gets it done for you, this one is a good choice for you.
Mine works very well.

Ditto
I know as much as I can learn and try to keep an open mind to anything!

If I didn't overthink stuff I wouldn't be on speedtalk!
