Im running a 408 , 5 disk 3200 stall , 342 gears with a 238/242-605/610 -113+3 .

I had to move my converter lock up points to keep the car from lugging against the converter and that only helped a little .

The only real problem you will have is the 3200 stall is not going to like a 244/248 duration .

A 3600-3800 stall will be needed for that size duration imo .

Its gona lug hard against the converter at 50-55 mph in over drive , 3rd gear locked at 40-45 is gona be bad also for a DD .

If you drive the car every day like i do a 244 is gona suck , that big of a duration will make great power in the 510-525whp range but as a dd you might not like it .

I have to order a new cam monday because one of my lifters was messed up during assembly and im going to stick with the same size and specs i have now .

Great power and right on the edge of drivability .

Also , a 244/248 will bog a little against a 3200 stall off the line because your not going to make power with that cam untill 3600-3800 rpms .

The only reason i get away with a 238/242 and a 3200 stall is because i spray alot which makes my converter flash higher .

Oh , and i just noticed your weight is 3500 lbs .

244/248 + 3200 stall + 3500 lbs = sucky launch's.

Merv has a 3600 stall , that why his car drives ok with a 243/247

Stick cars can get away with big durations while us auto guys have limits
on our durations for driveability

I plan on having my converter restalled before the motor goes in, I guess I will go 3800 or so and a built trans and 12 bolt. Thanks for the info guys.

408 cubes and still not enough? go bigger because you need to attain some kind of tractability keeping it sorta a tad docile at the lower revs with them cubes and when your ready for buisness
hang on!
i'm out of here!

So what kind of #'s are you putting down, what stall/gears are you running what is your drivability like...I am 99% sure Erik K. will be building my engine too. I can't wait to get it installed.

With my ported fast 90 setup I pulled 520rwhp and 500trq at the wheels. I have A4, 3200 stall, 12 bolt with 3.73 gears. And the tune and stall is set up for the spray. I get 225rwhp with the 200 shot!! Sold thay intake, got a new one being put on this week ported from someone else. Will see the new numbers next week! I can smoke them from a 50 roll like nothing!! I have a SD tune and she drives like a baby!!

Beards 373 gears help with that big of a duration because it puts his stall lug at a different point in his cruise speed , but at the same time a 373 gear with the A4 pretty much makes 1st gear useless so to speak .

He is also spraying , that will instantly flash the converter to the 3500-3600rpm range which about right where his cam is starting to make good power .

And Beard , dont let anyone fool you , if your making 225 on 200 shot jets , its because they are 225 shot jets , no matter how they are stamped .
Its the torque that will be super impressive and off the chain with the stroker motor .

Beards 3200 stall make it easier to use around town without being to anoying from light to light . A 3800 stall is going to be anoying in traffic and from light to light type everyday driving .

Excessive , look at the combination and learn from the combinations that others have before spending your hard earned money .

Purpose/Cam/converter/gear are the main things to iron out because if one is off , the rest wont work the way you want or imagine .

So far , your 244/248 with a 3800 is gone rock but with what gear in the 12 bolt ?

Also , with a 244/248 // 3800 stall your gas mileage in the city is gona instantly drop to 12-14 mph going from light to light in traffic if that is any concern .

Do you do a lot of highway miles to and from work ? ,, gota take that into concideration also .

It all make ya go ,, hummmmm

Thanks for the info. I was thinking 3800-4000 stall and 3.42 gear 12 bolt...I found a 242/244 610/612 cam on a 113+3 LSA. What do you think of this setup...enough stall/gear or no for that cam? I only drive 1.3 miles to work...all other driving is for pleasure.

Do you have any plans of spraying the car or using a power adder in the near future ?

If its strickly N/A a 3600 will put you right on the power band of a 242/244 cam and will launch like a rocket with drag radials but still give you some crusing ability with the 342 .

imo thats setup is gona rock and only driving 1.5 miles to work , traffic is not a concern anyway.

3800-4000 stall on the street is a little to high imo for a dd .

No spray for me...replacing the stock block due to piston grenade...why do all the work to go back to stock CI? So I decided to go bigger, bigger cubes, cam, TC, gears, rear, and trans to hold up to the new engine.
