Trying to find out if there is a difference in converters between a 250 6 cyl C4 and a 302 C4, thanx guys, Dave
There is a small difference in the stall speed but nothing that you would notice driving the car. THEY WILL INTERCHANGE IN BOLT PATTERN AND THERE IS NO COUNTERWEIGHT ON THE CONVERTERS. In short you can use the 250 converter with your 302/5.0l
the 250 one should stall a little higher behind the 302, but it all depends on torque.. if i remember correctly.
The converter from a 250 has a slightly higher stall speed that will go slightly higher when put behind a 302. If you put it behind a 429 it will have a higher stall speed too. It all depends on torque and HP.
I've always wanted to know that too Gene. Everyone keeps saying they want to get a new converter for higher stall speed. . . don't get it.
So a lower stall # is generaly better? Can having a higher stall make it feel like a rubber band? Horrible description... kinda slugish at take off. Who can calculate what is best?
So basically a stall "determines" what RPM your car will shift? If its a street car you want a stall of whatever you normally would shift at if you had a 5-speed, a race car would see a stall typical of near red-lining? I know nothing about stalls, so thats why Im asking...lol
K. Thanks. :Handshake Edit: I looked up my cam and found info at the site. I'm still gonna call and ask some dumb questions. http://www.compperformancegroupstor...C&Product_Code=31-330-3&Category_Code=SBHFTCM
Just to clear things up a little more, a torque converter is only used in an automatic transmission. The 5 speed manual uses a clutch disk and pressure plate, where the stall is controlled by your left foot and clutch pedal. That is assuming that the clutch is good and not so burnt up it's slipping. Hope this helps, -Scott H.
