Torquer 383 and a stock 700r4

[Dain Fraser]

Do you guys think my stock 700r4 (with about 25 miles on it since installation) could withstand this GM torquer 383?

Good torque converter and BIGGEST tranny cooler you can fit.

 

[Dain Fraser]

Excellent (rubs hands together)

for the $4000 US pricetag, you can probably build an engine with some better components, and still have money left over for other mods (torque converter and tranny cooler )

Get a used 350 block, some decent heads (scoggin dickey's got some good ones for a fair price), cam+tappets, 383 kit (crank, pistons, etc), and intake, all plus machine work should be about $3 grand for a bad ass 383.

I ended up spending $3000+ when I built my 383. Or 388 rather, its now been bored .060 and is a 2 bolt main. Thats a 4 bolt main ALL NEW. And its a roller!! He can rebuild it 2 maybe 3 times, And when he does he can pump it up to 500 HP if he wants. I like how it makes over 400 pounds torque from 2500-4000RPM. And peak HP is at 4500. With a redline of 5000RPM and 9:1 compression. Me lilkey!!

My build up has a 2800 dollar stroker, but I didnt have to pay for heads or block, but Im gonna be running a fairly stock 700 r4 with only an upgraded sunshell and shift kit, so we will see how it fares.

Let me guess, "sunshell" another slang term for torque converter? I think I can see why.

no, a sunshell is an internal part. part of the planetary gear set i do believe.

No, the sunshell is a big, well.... shell. I has most if not all of the clutchplates in it and carries the load of the engine.

a run of the mill 3.75" stroke / 4.030" bore 5.7" rod 383, with 28cc valve relieve pistons, .015" deck, .025" head gasket and a set of Vortec heads (box stock) with an XE256 in it will do nearly the same, for probably pretty close to half the price. if you build it right, you wont need to build it 2 maybe 3 times.

according to desktop dyno, this one makes 400+ ft/lb from 2000-4500 (2000 is the lowest it will go) and 322 hp at 4500 rpms. with a little detail work during assembly, it is highly likely to surpass those numbers without changing any parts.
