Max HP stock 200-R4 and 10bolt rear end can handle...

[87MC_SS]

Im getting ready to purchase a 383 stroker out of a 67 Chevelle. 400+ HP and Torque... at the crank.. I had my 200 rebuilt about 8 months ago. nd I have a posi 7.5 rear end.. How long do you think the two will hold up with that motor?? Im looking for a bigger rear end but I know it may take a while to find one worth buying.

I'm speaking from what I've heard...
... when you say "rebuilt 200-4r"... does this include shift kit? or simple replacement parts? What kinda stall? Any oil cooler?
That 383 will probably like a +1800rpm stall convertor. Stock internals on the trans will likely wear out soon. An additional oil cooler will increase your trans' life and keep it healthy.

The 7.5 rear should be okay for now... try to be gental. Avoid slicks. And if you're having fun at a red-light... give it a gental start and hammer the throttle after you're up and moving. The key is to make sure you don't hook when you're dropping all 400 horsies on there...

A stock rebuild on the transmission.. for now this is what i will buy for the transmission the 449.00 kit http://www.ckperformance.com/resources/ ... DKITS.html

where can I find a oil cooler for my trans at? and no slicks, just good ole daily driver firehawk tires.

any auto parts store should carry it. It's fairly universal and largely used for 4x4s and towing vehicles.
I've seen two different kinda trans oil coolers...
#1. old school style:

#2. new school style:

I went for #2... This kinda actually has the oil lines built into the fins like veins. The old styles are hardlines with fins attached to them. And I find it's easy to ding up those fins and damage the lines.

I installed a 11" x 12" cooler in mine, biggest I could get. I was using my car this summer for daily driving, and during rush hour the oil sometimes climed to 200 deg F. And it would get real hot at the strip too.

If you plan to thrash on your trans as much as I do, it's definitly a good investment. Although an 11x12 is kinda overkill, you should be okay with something smaller.

I routed mine seperate from my rad... but it does fine because I have dual electric fans. Alot of folks say to route it in series with your rad oil lines so you get double cooling.
(I'm not an expert on optimum oil temperature, so I won't comment any further on this)
But with my cooler routed seperate from the rad, the temp never climbs above 150 deg F.

Mine is a Mr.Transmission brand. It came with brackets or zip-ties to attach to the rad or any other mounting surface. It also came with addtional fittings, and a nice length of pressure hose.

How much did it run you?

fawk... bad question...
well, I didn't do my research, so I just went to PartsSource and dropped a $100 for my 11x12...

later I found out, they shouldn't cost much more than $50, even in that size. So just look around. A dealer will likely be expensive. Napa or some small chain parts stores should carry is cheaper. You might even get a cheap deal from a independant shop.

I'm up in Ottawa, Canada... so I can't really say where you should look... I just know it's more expensive up here.

thanks 4 the input

I'm using a condenser from a car out of the junk yards, has a built in electric fan...thats the cheapest route :wink:

If you're junkyard shopping, check the transmission cooler on a recent dodge ram pick-up. They are huge!!
That's what I will be using

From what I have read ideal operating temp for trans fluid is about 170 degrees. ie after its been through the cooler or radiator. An extended time with temps in excess of 210 will dramatically shorten your fluids life and if not changed your transmissions life. BTW trans temp guages are cheap and easy to install.
