Street Master torque converters are designed for the driver who is looking for a competitive advantage. By raising the stall rpm, these converters will completely eliminate slow, sluggish starts. Recommended for stock to slightly modified engines for maximum performance, they'll allow the engine to idle smoothly when the car is in gear. All stall speeds are approximate ratings for fresh big block engines. Small blocks will vary 300 to 500 r.p.m. lower.

Q:

Looking at the Hughes application chart on their site, it says this particular converter is a 6 pad. The description here says it comes with 3 mounting bolts. Is it a 6 pad or 3 pad?

Asked by BARRY on November 30, 2017

A:

3 pad

Q:

I have a 1986 Chevy k20, th400 and 4.10 gears. Rebuilt 355 with a COMP 12-600-4, 600cfm edelbrock carb, edelbrock performer intake, and hooker long tubes. Peak torque is 2900 rpms on the dyno at the crank. When I put the truck in gear, it drops rpm’s and dies no matter how high I set the idle. Would this be the correct stall and would this help the problem at all?

Asked by DILLON on March 05, 2020

A:

I recommend GM25MAX STALL

Q:

I have a blueprint BP3834ctc1. 420hp / 450 ft/lbs. Also, a rebuilt th350. Going into a 1970 c10. Just curious if this would be a good choice for my build. Engine specs call for 2000- 2400 stall but from the little bit of reading I've done, it seems like this would the right way to go.

Asked by JASON on March 23, 2020

A:

The cam profile for this motor is 220 Intake / 224 Exhaust duration @ .050 at 114* LSA.
The GM25 would be a perfect choice

Q:

I’m going to install the edelbrock 2058 top end kit on a 1969 Oldsmobile 442 with a 455 engine. This car has the original W-30 TH400 transmission. Edelbrock recommends 2500 torque converter. Would this be the one to get ? If not which would work the best for mainly street application.

Asked by THOMAS on March 01, 2020

A:

GM25HD is the correct part number

I consulted Hughes with all the specs of my '77 C10 (engine, gears, cam, compression, weight, usage, etc), as well as how my existing combination with the stock converter was performing. Hughes recommended the GM25, and I am very very very pleased. It actually idles in gear now, the converter appears to be stalling right around 2400rpm for me, and drops 150rpm off throttle on the highway. This is my first stall converter, and it drives just fine around town, much like a stock vehicle on light throttle. Hughes customer service was great, and a big persuader for me in purchasing this converter. ...read more

Purchased this converter for a 74 C10 with a mild 383. Works really well. No problems with shipping. No issues with instillation. Works really well for the street and some weekend track use. I would recommend this converter.

Have put Hughes converters in all my cars -2 X Pontiacs and 1 X 66 Impala. They perform flawlessly every time! I find the 2500 stall works the best in casual street machines! Excellent quality and perfect fitment!!
