I am in the middle of putting this new combination together and I thought I would see what everyone thinks. The motor is a .030 over 383 with a muscle motors 489 stroker kit. It has 10:1 compression, 440 source stealth aluminium heads with crane adjustable 1.5 rocker arms, any suggestions for camshaft and carbeurator. I do have a 750cfm double pumper, but I am debating if that might be to small. I called hughes racing about a cam and they suggested an HEH4246BL which has .555/.569 lift and 242/246 duration at .050" installed at 105 degrees. What do you guys think about the carb and cam? 727tf with full manual valve body, converter suggestions are desperately needed! 8 3/4 with several options for rears. I have a 489 case with a full spool and 5.13gears( I was going to use these for 1/8th mile strips). I have a 742 case with a full spool that I was going to put 4.10 in for 1/4 mile tracks. And finally I have a 741 case with a lock-rite and 3.23 gears for cruising and street driving. The car has 29 inch tires and weighs 4400lbs w/driver. Any and all opinions are welcome seeing as this is my first build, and I am trying to make sure I get everything matched correctly for optimum performance. Thanks Moparts.

From a race standpoint:

That is a tiny cam for a stroker and the low end torque will be beyond massive with the small ports of the stealth heads /750 carb.
--It will peak early and low.

That cam/carb combo would make for a very torquey, rip you neck off, street car.

Drivetrain:
- That 741 pumpkin will die a fast, horrible death with that motor.

- You will break that 8 3/4 at the weight you are pushing around. 4400lbs

- Don't put any money into a 8 3/4 for your application.

- Sell all the 8 3/4 parts before they are busted.

Also remember, when you bust a rear end it usually wounds the trans.

Before you start breaking parts...just buy a Dana.
It will save you the pesky future expense of buying a Dana, a new transmission and possibly your feet/life.

If I need to go to a Dana, will a Dana 60 out of a truck work to shorten and get different axles??? I have a completely rebuilt Dana 60 out of a 1 ton truck I have that we rebuilt that has 4.10 gears in it.

I can either run my Mopar M1 intake with a single carb, or I have a ported Offenhauser tunnel ram that i could get twin 600's or 650's. Thoughts???

Cam with a little more duration. Depending on gear choice the T/A "tight" 10" is a nice piece. I think the life of the 741 would depend on your traction situation and how hard you are on it. Others are right saying it will be the first to go, but I had one for a while behind my 2 ton car with a stroker and it lasted, with street tires. Jusy my I'm sure others on here can help alot more than me though.

Ok, I will try to locate one, thanks.

Anybody have an opinion on which would work better for this combination--a single 750 dbl pumper on a mopar m-1 intake, or two 600-650 on a tunnel ram?????

I found the converters that are 10", but what exactly do you mean by tight?? Is that a lower stall, or a higher stall??? Thanks.

T/A makes 3 "types" of 10" street converters. The "tight" one is the tightest stall of the three. It drives very well, but flashes good when needed. I think it is 17805ST.

4400lbs + 489" = Dana 60 and big U-joints.

Ok, thanks for all the help so far, I really appreciate it, and it has helped me alot. My next question is exhaust for this combination. I have hooker super comp headers on the motor, and was wondering wether I should run 2.5" or 3" exhaust with this combination?? I will have cut outs in the exhaust, and also what is a good muffler??

Yes you can use the dana from a truck with 8 3/4" ends and the correct length and spline axles. Get the 1350 yoke for it from the start as well.

The MI works well on strokers and will be easier to tune than the Offy. Performance will likley be better also. I'd go M1. The 750 is a bit small but should get you started. If you plan to street drive it I think the 242@.050 cam would work great. If its more or mostly race then biggger.
