LS1 240SX Build
Started parting the car out and it's now basically a half sanded, cut up rear fender rolling shell. I wanted to start over and do a full build.
Used to look like this.

My motor. Chevrolet LM7

Dropped off at the machinist:

Plans:
Block / Bottom End:
- Bore and plateu hone block. soft hone quick ring seating (5.3L to 5.7L)
- 3.903 bore
- Deck block
- Grind 3.622" OEM Crankshaft
- Balance rotating assembly
- Line hone block
- Check and set main bearing clearances, rod bearing clearances, ring gap
- Install cam bearings
- Wiseco/K1 Billet Rods
- Wiseco Pistons 12cc dome / 3.903" bore 12.4:1 CR
- Clevite Bearings
- ARP Main studs
Head / Top End:
- Performance 3 angle
- Surface cylinder head
- Porting + valve job and surface for 243/799 heads
- ARP Head bolts
- Stock head gasket
- Texas Speed Magic Stick 4 239/242 .649"/.609" Camshaft @ .050"
- Comp Cams Beehive dual valve springs, lifters, pushrods, rocker arms
- Manley Valves
First stage of machining has been done.
The valve job + porting should make the 799 heads flow to around 315cfm. Around the specs of the AFR 210 heads.
It will be fully caged, repainted, widebody/overs, new wheels, new suspension, etc. Everything. Going to do it right. So shut up if it takes a long time

It should be fun. This is the first full motor build I've ever done. Lots to learn on the way.
Like my neighbors TT 300zx with about 20 degrees of negative camber and stretched tires. He was kinda embarrassed in front of his 10 buddies after he talked SO much crap and lost to my stock SRT-4.

.Goodluck with the build. There are a ton of 240sx conversions on here if you need any info. There should be more than enough info as far as fitment and combos go for your swap. If you haven't figured out motor mounts, oil pan, etc, a quick search should give you everything you need.

Yeah, I've been around plenty of swaps in S-chassis cars. I already have a modded GTO pan but it wasn't very well built, so I'm going to ditch that for a Sikky pan.
Mounts I'll be going with Daft, harness from either Chase bays or Wiring Specialities.
Long ways to go to need to think about the rest of the swap, so I'll get it to it when I can. Thanks

GL on the build I will be keeping a close eye on this one. Looks like you already put some work into this bad boy.
PS...shameless plug but if you need an Fbody Balancer for the swap I have one for sale. We could work something out.

I have heard mixed reviews about Chase. So I will probably be going with WS.
Wiseco +12cc domed pistons 3.903" bore. K1/Wiseco billet rods. Static CR should be right around 12.5:1

Block is machined and ready to be assembled. Just waiting on some backordered ARP main studs.
