the 1993 finally blew her motor @ 133k miles... Im gonna put togeather a 383.. does anyone sell any kits (crank, rods, pistons..etc..etc..)? for those of you who have done it is there anything that you know now that would have helped to have known when you started? Where are the best places to get the parts? Also, I have an auto tranny with 2.59 gears.. what cam is a good selection?? hotcam? thanx

 

Summit sells 383 kits, but Id pick and choose parts from several makers. Like Lunati rods, JE pistons, Scat or some other forged crank.

It depends on how wild you want it to be, that will point you to what exactly you need. Like if you want it to be bulletproof, go all forged, but be prepared to fork over some dough. If youre never gonna go with N.O.S. or a Supercharger, you can easily go with Hyper pistons and PM rods like comes stock in the LT1.

Need power goals to pick a cam too. 383s can easily handle cams with ~220/220 duration @ .050" or bigger with no real problems. Hotcam is the LEAST id go with.

 

Call Mike at More Performance,

He sells a 396 kit for $1999. It consists of a Callies dragon slayer crank and Lunati pro mod rod along with a JE piston.

Clearancing the block on the LT1/4 is a real PITA. But if you send the block to Mike he will do it for $150 on his CNC machine. Well worth the price to me.

Also rod selection is critical. The Lunati Pro-Mod has a "stroker" profile that helps to minimize interference with the block and cam.

 

I know where you can get :

<P>
4340 Crank - Internal Bal.
4340 H Beam Rods
JE srp Forged Pistons w/ pins and locks
JE Rings

All of Eagles Finest... for under $1500

Trust me... I shopped around everywhere before I found this deal....

 

Where?

 

Will I need to move up to a 52mm throttle body and long tubes?

How is the $5700 engine different from the $1999 396?????? Other then one is a 383 and one is a 396 :confused: :confused: :confused: :confused: :confused:

$1999 is just for the rotating assembly. $5700 is for the complete assembled shortblock.

BluByU is looking for a "kit" not a complete motor.

 

So who can give me a ballpark cost to have my LT1 turned into a 383? I'd prefer to go with forged parts all over...maybe about $6K?

How hard is it to find a shop to do this kind of work? Seems pretty common to do this motor (probably second only to the 302), so how do you pick the shop to do it?

 

I've got $4500 total into my 383. I paid the machine shop $2000 for the 383 conversion which included forged parts and then he ported and polished my heads for $400 and then I have about $2k in miscellaneous parts like all Comp Cams Pro Magnum valve train, a custom grind cam, headers, electric waterpump, 58mm TB, broken sensors and stuff, etc.

 

Will the 383/396 require a bigger than stock throttle body? (52mm over 48mm?)

 

You will need at least the 52mm throttle body if you are doing a big cam and ported and polished heads and all of the good stuff.

 

ScaryFast:

If you are thinking going to a 383, I may have some stuff to get rid of. I just bought a project car with no motor in, and with it I got the stock 350 shortblock, and a 383 shortblock. I don't know much at all about the 383, other than it has high dollar rods in it (Eagle?) and very low mileage since the build. I'm going to build the 350 for my car, and may consider parting w/ the 383 stuff. I know the rotating assembly is fine, but there there is a big :confused: on the block. The guy I bought it from had a water problem. Could have been a head (hope not, I plan on using them on the 350), head gasket, or block. He never knew for sure. I've also got a Canton race pan ("wings" on the bottom) that has been clearanced in the front corner for the 383 install.

If you are interested in this, e-mail or IM me. I picked you out based on your post and location. I'm in Brighton.

My buddies LT1 is being picked up today. Nu-Tek is doing his 383. Do some research on them, a very reputible shop and they specialze in LT1's.

 

I bought all of my pieces on eBay. I still have fuel injectors and a cam to get to be finished with buying. What I bought and prices as follows:

1) A NEW GM High Performance 4340 forged 3.800 stroke crank for $750+shipping.($1400 retail)-works out to be a 388ci.

2) New custom JE forged nitrous pistons with rings, pins and locks.
$400+shipping.($700-$800 retail)

3) Used Carrillo rods-perfect and guaranteed with new ARP 2000 bolts.
$495 shipped.(new- ~$1400)

4) Used 2 bolt main block.
$200+shipping.

5) New Eagle splayed 4 bolt main caps
$79+shipping.

I got $3800-$3900(retail-which would be a little cheaper by going through vendors) in parts for just about half of that + about $250 in shipping charges(the block was $150 for shipping itself). I also had the luxury of waiting for these pieces to come available as well and that makes a big difference. All total, if I didn't need the block and main caps, you would be looking at about $1700 for the rotating assembly(oh, throw in another $100 or so for bearings). And that is for some of the best that money can buy. If you can afford the time, shop around- it's out there.

I have a 383 from Scoggin Dickey(see sig). I've put on over 40,000 miles on it and I'm very happy with it. they sell a 383 short block, but i don't know exactly for how much.

But if I could do it again, I would probably opt for the 396. The extra cubes is always good in my opinion.

good luck,
joel
