For about 2 weeks I've been searching here for infos and I found too many set up possible so now I'm confused.

Here's what I do with my car 1st . :

1994 LT1 T56

- I drive my car only on sunny days to cruise around town , I may hit the 1/4 mile a few times a year . I want this thing to be very drivable & reliable to cruise around town.

Lloyd Elliot suggested me his LE2 package with a ported intake and a camshaft with 223/230 .565/.565 112 LSA . ( bought it already May 2010 )

I will not spray or use any type of supercharger and I want a nice flat "torque" power for street use.

I want to get a rotating assembly to be able to put together a 383 CI that will be machined here locally .

I've heard "cast" , "nodular" "forged" crankshaft and I've heard rods that need to works with "regular base circle" camshaft ( what ever it means ) .

I'd like to know what you guys will suggest me for
-: Crankshaft .
-: Pistons ( with dish or not ) and brand .
-: rods that will work with "regular base circle" camshaft ( if it means something )
-: Oil pump ?
-Misc stuff I may forget.

I had the impression I was going to be able to figure that out myself but so many choices and options.

I'd like to spend around $1500.00 on the rotating assembly if possible.

I'm not building a race car , just a small car to have fun around town so please don't go too crazy with your suggestions. ( $$$ ) .

Thanks in advance for your help and knowledge.

You are probably going to spend more like 2000, for pistons, forged crank, bearings, rings, and some 6in h beams. My eagle 6in H beams clear the cam easily, but have to be clearanced for the block. As far as the oilpump goes just run a regular M-55 melling.

I will disagree with you on the M55 Melling. Their housings have been known to break because of the weaker casting design (that's why they are so cheap). If I was the OP, I would go with the Melling SELECT line of pumps (particularly 10554).

2K is ok for me also.
See we have two reply and already we have 2 different opinion.
Do I really have to go with forged crankshaft or cast "Nodular" what ever the difference is , will do the trick ? I don't think I'll be over 400 425 RWHP with my 383 LE2 setup and the restricted exhaust & headers I'm running right now.


Keep the comments comming , I'll pick what I think is OK for me.
This is a good debate and can be good for other members with a similar project too .

Damn yea that's what I have, I just meant don't run a HV.

This is the other things I'm running.
Eagle 3.8 Crank
Eagle H-beam 6" Rods
Wiseco Pro Tru 4.030" -13cc Pistons

You will want to use a 3.75 crank to get you 383 and make sure its forged and pick your brand.
Here is some pictures of them

well my setup is from clayton racing engines and i paid 1780 shipped for my scat rotating assembly. all forged with 5 cc dished pistons and the arp 2000 rod bolt upgrade with all the bearings i needed. i also use the meling select pump. i was inforrmed by clayton racing that this setup would support 750-1000hp and i belive 8000 rpms. i think you could get the same setup minus the rod bolts for 1700 and it would support up to 700 i think. this is the only setup i have used but i love it with my le2 heads and custom cam. it would be overkill for ur setup. but 200 extra dollars might be worth while in this case. i hope this helps, if you have any questions feel free to pm me.

Good info.
I'm always running 91+ Octane so what compression ratio & "cc" "dish" pistons I should get ?

kalebm22

iTrader: (2)

the tune is the most important part. i am running 12.5 to 1 compression on 91 octane but i have a little more cam than you. i think around 12 to 1 would be a good setup. which i think you can get that with a 10 cc dish and a thin head gasket. others need to chime in on that tho. my heads were milled .030 thousands the get 12.5 to one on my 5 cc dished pistions.

I already bought a Mr Gasket 5716 head gaskets .026 that Lloyd Elliot suggested me to get.

Have you dynoed your car ?
I'm curious to know what you have at the rear wheels.

kalebm22

iTrader: (2)

yea i did, but it wasnt getting enough fuel so we shut it down early. hopefully it will put down 450rwhp with a good tune and enough fuel pressure

Someone has a 4 bolt main LT1 ( core ) , what question should I ask him to make sure it is the right block for my built ?

fex77k

iTrader: (2)

To find out of its even remotely right I would make sure it didn't have a mechanical fuel pump boss and the 4 water pump holes on the front of the block are two easy ways to weed out a bunch of blocks. Then get him to tell you some part numbers off the block. Shoebox had good pics of all of the locations.

mpcv2000

iTrader: (1)

Perfect .
I'll make sure I double check the part number 1st before investing money on it.

Still haven't bought anything for the short block yet but here's what piston's specification I was suggested to buy :

Something with a negative piston pin ( what ever it means ) with preferred -10cc dish or -16cc .

I'm unable to locate some -10cc pistons but -16cc is pretty commond.

What you guys think of this :

Forged 383 racing rotating assembly for LT1 LT4 and all late 1 piece seal blocks

SCAT Forged 3.750 stroke crankshaft
SCAT Forged 6" H Beam connecting rods
MAHLE Powerpack forged Flat top coated piston kit ( to be confirm *cc* )
MAHLE file fite ring set
ACL Race engine bearings

Looks like I need to make sure the rods will work with a "Standard base circle" camshaft .

Any suggestions where I should get all my parts ? ( sponsor here , well known shop etc. ? )


Thanks.

There's no reason you should be running a dished piston. A flat-top with standard valve reliefs is all you need (most commonly -5cc) to keep the compression up.

kalebm22

iTrader: (2)

i agree! valve releifs is all you need. call corey at clayton racing. he will tell you exactly what you need and has everything u mentioned. those rods will clear a standard base cam just fine.

vetteboy99

get a 383 forged kit for around 2000. Whole bottom end Except for block
