I guess that's a yes

I'm not a torque converter expert at all, but I'd guess you would want your stall around 2500. That's one of those things I play around with for test and tunes.

OR..
you could call Coan or another like company, tell them your full setup, what it's for, and have them tell you.

I put a JM 20-22 IN MY 73-350. 496 lift, 226at@50. In order to keep it running when I dropped it in gear it had to idle at 1150rpm. What a thump. I put in a B&M 2500 stall and I was able to turn down the idle to 850 in park.
With a 230@50 on your cam you might have problems with power brakes at an idle. tHEY MIGHT FEEL LIKE YOUR PUSHING ON A BRICK TO GET THE CAR STOPPED. You might need a vacuum canister for your brakes.

I would think that in a 355, you will need 10.5-10.8 to 1 to make it idle decently and have enough vacuum for the brakes. You probably won't be running pump gas.

Taking into consideration, that "Streetable" is a highly subjective term, as it has been applied to everything from a "stocker" (with a K&N, MSD, and a pair of Flowmasters) to a full on "racecar" (with mufflers, current registration, and insurance).

That cam (with a matching advance curve) can be a good choice for street use.

AC is not a factor. Whether PB are, depends on how the engine is tuned and the conditions when they are used. See "streetable" above.

There are reserve systems (PDF download) for use in "marginal" applications.

Not subjective: Compression ratio depends on what fuel is to be used. 9.0:1 is usually suggested, as a starting point, for use with pump gas.

Converter stall speed is subjective: Depending on your intended use, your tires/suspension, and the rest of your powertrain, It might be anywhere between 2200 and 3500 RPM.


Compression ratio has no effect on the idle

and little, if any, effect on the function of power brakes.

Remember you can always advance or retard it to help give you what you want.

If you advance it 4-6 deg and it helps noticeably then you probably have the wrong cam for your application and wants, (too big).

If you retard it and it has the same effect then you could've probably gone a bit bigger.

Vacuum is very important in a street car.

The JM 22-25-10 is Streetable, the 20-22 is a good one too

71olds350, you'll like the 22-25-10 its a good low end builder and yes you'll need a 2500 stall, mine will have the mondello roller tip rockers, guide's and push rods w/ studs, this winter, my comp is 9.3

im also building a 2004r overdrive tranny so can i get a 3000 stall with lockup? or to much slip on part throttle. im also wondering how much horsepower is my motor going to make with 7 heads reworked bigger valves, 10.3 comp, 22-25-10 cam, edelbrock rpm intake, 750 edelbrock carb, headers, x pipe and flowmaster 40s. just curious

1971olds350

does any1 know how much horsepower and torque 22-25-10 makes

call jr or lynn at mondello at 805 237 8808 calif time zone they will tell you that info, best plan on valve springs? am building 75 350 block pistons and rods with 65 330 heads#2 and the 65 330 crank, hope this info helps you out, gives me 9.3 cp and using 22-25-10 cam and yes its good with power brakes
