You have to have custom bends and what not I believe. I’m not sure I understand it all yet, all the fabrication rules.

I'm running one of them propeller supports. Not because V8 but because drivetrain length due to doubler. I got these for mounts

Man I agree. I’m initially wanting to buy time. I was planning to do the LS in another year if it survived that long. It honestly ran great minus smoking at idle when hot.

However to do an LS I’m going to be another 3-5 deeper, unless I bolt it to my 4 speed and add the 5 speed later down the road. Which I don’t really want to do. If I did mate to the 4 speed I would need a 60 shift plate for my trans. My shifter is plenty close to the heater now so there is no way I could move the drivetrain forward enough to clear the firewall (I think)

Engine $500-800 plus gaskets to freshen
Fuel pump $300
Manifolds / headers $400-500
Motor mounts $200
Split case $500-$2000
H55 parts needed to finish $800
Crossmember / trans mount $200
Exhaust $250
Wiring supplies $100
Clutch and flywheel $500
Drive shaft mods $250
I’m sure there are other odds and ends I’m forgetting.

Basically 4-6 grand to LS swap and the down time.

F engine repair -
Gasket kit $150
Piston $80
Rings $90
Bearings if I go there $65
Plus machine shop at roughly $500

I can have all the parts and start putting back together in a week or two.


But dammit you have my wheels turning.

I apologize for being late to the thread, but I see what strikes me as a glaring omission, unless you are an LS wiring and computer guru.

The vast majority of people who do LS swaps purchase a conversion wiring harness. It makes the swap way, way easier. Many conversion harnesses are a four wire hookup. But they cost money. I haven't bought one in a while, but I'd guess about $700, or so. Assuming the engine you purchase comes with a computer (or ecm, as they're called), you will need to get it re-flashed, which will add another couple hundred bucks. If you are planning on running electric fan(s), make certain the conversion harness has wires for those fans in the harness.

You may be able to use stock, or slightly modified, factory exhaust manifolds which would save some money.

I'm a big fan of LS engines. Yes, there's some ass pain involved but after your rig is finished you'll be glad you did it.

This will be my 3rd swap using a factory modified harness that I did myself. It’s honestly easy just time consuming. Tuning the ecm is no issue as well.

Although this time I did splurge and bought a nice fuse block for the harness.

I too love the LS platform.

I’m going to see what happens with stock manifolds before I order something. I have thoughts in mind.

I'd be curious to hear or see what you have. Most all V8 conversion(AA or Downey) I've seen with the stk 4speed(h42) & Tcase use a rear propeller crossmember.

No propeller crossmember….it looks to me like the H42 bell housing remains, and there is a bell-housing adapter from SBC to H42 bell housing. Best i can tell, the h42 bellhousing and supports are in the original location, and i believe this is supported by the fact the original h42 shift plate is still in place, and the shifter is in the factory location.

What does your adapter look like?
 
You’ll want to get a pair of Summit G9080 manifolds. Don’t waste your time bolting the stock ones back on.

Good deal on the 60 axles.. I would put the rear axle in all day, that’s an awesome easy upgrade. The front I would sell and recoupe since you already have a disc conversion.

Thanks for the manifold part #

Just run spacers in the front?

My only gripe about spacers on the front is my lockout will be inside my hubcap due to my wheel setup. Currently flush

I am duly impressed by your skill at modifying a factory harness!

I know the NV4500 was mentioned earlier, and some of the ones listed have absurd asking prices. This one doesn't seem unreasonable at $1,200:

Is that with a spacer now?
You certainly can put a 60 axle under the front of a 60, but the front diff and right-side leaf spring get very tight.

No spacer now. The wheels are pretty thick. 17x9 Fifteen52 aluminum.

I have plans for the 60 axle swap that doesn’t involve front leaf springs. However this LS swap might delay that some.

Ok I see what you are saying now. If you put spacers on it will be wayy inside the hubcap.
Carry on. let me know if you need any help with 70 or 80 series radius arm brackets or spring mounts if that is what you are thinking.. we can get everything :)
