LS horsepower

AJ engines

A different block, heads, and intake at the least.
The LS engine was somewhat derived from the Jag engine, but it is not the same. I don't think the Jag block will mount to the LS transmission, and the LS electronics can't handle the Jag heads (different valve timing controls), or the intake.

Politely, joegr, let me suggest that you read 'Land Speed LS' first and then join the conversation. If you want to do the same sort of swap that is involved when you replace a radiator cap, you're correct in your evaluation. Not otherwise.:) :) :) :) :)

In regard to shocks, Sully, it's necessary to make adapter blocks that change the LS mounts to accept the Heim ends that come on race shocks. It's figured out, but I haven't had time to do it yet!

With all due respect, this thread started out about a gen II LS and I assume that is still what it is about, not gen I (which wouldn't have the valve timing control issues.)

Here are facts---
'Fitting' considers two areas.
1. Physical installation may require minor crossbreeding, but all major components bolt up. (Jag has oil filter on right front and LS is right in front. At its most drastic, this could be solved with aftermarket adapter and a couple of feet of stainless braid.)
2. SCT re-tuning will readily alter any electronic interface problem.

I repeat---it takes more than changing a radiator cap and about the same as installing an FE engine in my '63 F-100. Not a giant job!! Not as much as putting a 460 in a Pinto Gen is irrelevant :D

Generation is irrelevant if you don't mind ripping out all of the gen II electronics and replacing with gen I, or losing all dash functions.

Of course, if you really want a Jag motor, then buy a Jag car, it will be cheaper.

Thanks for your input!!

Unless your input is based on hands-on information, you're likely to speak in error. Tell us about your 'dirty hands' experience. Please!

Thanks for your input!! (But first talk to someone with actual hands-on time)

Ken - have you got to the point where you can confirm this statement "SCT re-tuning will readily alter any electronic interface problem." - last I heard SCT said 'no problem' but did that mean 'no problem we have done it before' or 'no problem we can $work$ through this new challenge'?
 
SCT Mods

Hi Quik---
When I first looked into the computer changes necessary, I intended to use a Megasquirt controller. A local operation here in Metro Detroit suggested that I talk to SCT. Long story short, they have offered to support my Land Speed efforts and seem to be confident of their re-programming ability. Since I will lock out the VVT, I don't think we're plowing any absolutely new ground. But who knows, until we actually do it!

I'm not sure SCT can resolve hardware sensor profile issues. If the Jag uses a 24x crank sensor and the Lincoln uses a 58x crank sensor (notional numbers), then that is a hardware compatability issue and would require matching the sensor and wheel together unless SCT has more tuning capabilities than most tuners do for even the most common engines like the Gen III/IV GM V8.

I'm saying this as a concern not a hard statement.

As an example of problem-solving, the cam covers are interchangeable so alternate locations for cam sensors are available. Some of the concerns mentioned might be real killers if easy access (engine out) and interchange weren't 'on the table'. I simply repeat that SCT seem sure of their capacity.

I'm very familure with doing this. I have a 3800 FWD supercharged ECM and harness running my 4.1L RWD Buick V6 which involved swapping all the sensors and trigger wheels.

Just saying that its not generally an option to tell the computer to change the hardware profiles of most sensors involved as much as it is adapting the hardware. I'd also put more faith in hardware changes but I'm predominantly a GM guy so Ford might write their code so that you can change baseline tables easier and you can change things a bit easier.
