Starting the LS1 Swap

[eric1h]

i'll go C5R its a little more, but what is an extra $80 for some peace of mind! I ordered accusump today! I'll use it on the current 4.6 motor until I do the swap, another bit of insurance!

Be careful... there are some companies out there selling "C5R" chains that aren't. If you want 100% assurance then buy it from Katech. Tell them your a Corvetteforum member, because I saw a post stating that they have an "economic stimulus" sale right now 20% off all parts, engines, labor etc.

i saw that, I'll be ordering from Katech THANKS!

Look what the cat dragged up to my door mat!!








Some new info. Looks like the alternator will have to be relocated to the passenger side. It sticks out about 17" from the center of the block, and we only have about 14-15" from center otherwise the frame near the shock mounts gets in the way. So I'll have to machine a relocation bracket. they sell some, but $400 seems absurd for a hunk of aluminum!

What did that car come out of? Looks like Corvette accessories setup, but I've never seen a yellow oil cap on any Corvette.

FYI F-bodys and some other cars have a different accessories setup w/ the alternator in another spot... ther's like 3 different setups. Many people doing swaps have to use something other than the corvette accessories setup.

It's supposed to be from a 2004 corvette

How does one truly validate -- can you run the casting numbers or something like that?

[Cobra4B]

Well.... it's drive by wire so ti's from a Corvette... plus it's got all the accessories in the correct spot. You can look at the casting number on the front of the head on the passenger side and see which head it has on it. They should be 241s which denotes a 2001+ LS1 head. The LS6 heads are 243 castings.

Wait a minute... that's not a Corvette oil pan. C5s use a winged pan. The C6 LS2 changed the pan to a more "normal" pan.

C5 Pan... they're 2 part pans.

it has a 2 part winged pan, and 241 heads I did check that when i picked it up...

Started prepping the motor, I will need to relocate the ALternator to the passenger side. easy cheap fix.

[Cobra4B]

Well then I guess you just got a funky oil cap

[eric1h]

Just a short update on this... I'm making some progress on all the parts I need.

So far I have

Engine is ready
clutch, PP, flywheel and all clutch hydraulics figured out.
motor mounts are done
Quicktime bellhousing is "in"
accusump is ready to go
oil pump, oil cooler/filter relocation kit


really the last few things i need to get before I start the actual swap is the Tremec 3550 26 spline input shaft kit, ECU/wiring harness, and a few adapters for the fuel system. And then the last major piece will be the exhaust system, I'll either do custom long tube headers or modify some existing short tube headers!

anyway, just an update to let you know the project is not dead.

it's the little stuff that takes a lot of time figuring out, like which throwout bearing to use, which clutch arm, the actual bolting in of the engine should go pretty quick once i get all the other crap figured out.
