Is it hard to Swap LM7 5.3 into 95TA New to the lt1,i bought a very clean 95 ta with blow head gasket for $600..the engine has been disassemble to just a short block in the car still..Looks like the water pump maybe the culprit ,since the bearings were shot on it whhen i was inspecting parts that the owner took off,,,i know the opti spark basically sound like a nightmare and untrustworthy...i have a 30k mile 5.3 with a zo6 cam ,this was going to go in my Regal(aka GN) and twin turbo it...this ta is closer to finished then my regal...so how hard to do swap and whats needed...sorry new to f body cars..thanks DEnnis

It can be done and is becoming more popular to put a LS engine in a 93-97 fbody.
Cant say I have done it but I would think you could build a LT1 motor with 370-400 rwhp for less money than doing the LS transplant. Optisparks are not unreliable at all. I replaced the original opti on my car at 130k. Replaced it with a OEM Delphi and have had no issues at all. I have had several LT1s and optisparks have never been a issue.
If I was going to do a LS swap I would go with a 5.3 with a turbo or a 6.0 normally aspirated. Then with all that power the trans would have to be built up, then the 7.5 anemic rear end would have to be replaced with a stronger unit. But then again a 370-400 rwhp LT1 will kill the stock rear end eventually, especially if drag racing.

OK so motor is a short block in the car ,so opti will be easy to do and maybe fine ,but since i am doing things,why not change it.
to reach 370hp I would assume i need Heads and Cam,i have not seen heads for less then 800 and cam ,springs were pushing $1200..
I'm a GN turbo guy,f bodies are starting to learn the way of turbos,slap on a turbo for $400 and gain 150hp,I dont like spending 10,000 on junk,ported TB,lid evhaust,yada yada yada...
I have read many posts from 2008-2010 and it was a sin to yank the LT1 out for a 5.3,,but since we are in 2014 it seems that the consensus has changed,
,I think i need a K member (which)

LS stuff is expensive too. The difference is there's much more selection. From intake manifolds to heads, the market is flooded. But you can make more power. Towards 600 HP NA.
"Is it hard to Swap LM7 5.3 into 95TA"
YES. It's a lot of work, parts and wiring. It's best to strip a donor car.
You'll need an LS K-frame. I HIGHLY recommend an aftermarket lightweight K-frame from UMI or BMR.
1998 F-body cars have gauges like the LT1 cars so it'd probably make things easier to go with a 1998 harness & PCM.

The LS stuff cost a fortune, the truck intake won't fit so you will need to buy an intake. The truck accessory drive wont fit the car leaving you to need to source a car accessory drive which will likely cost you as much or more than a truck engine.
Top of the line tuning and data logging 94-5 LT1 with cable and no VIN restrictions is $250 twice that for LS1 VIN restricted.
So yeah the LS is vastly cheaper if you don't bother to comprehend, understand or consider anything involved in the swap.

The LT rack and shaft will not fit with the LS stuff. But, you can get a complete K frame with rack pretty cheap, and most yards around here will jut toss in the steering shaft with it.

I have a lt rack and steering shaft... and I have a ls2. ..it all works. Then again I have a bmr k memember not a stock lt one.
