The Helms are the best.

They don't show a '94 or a '95 LT5 Shop Manual set, but the '93 is the same engine. I'd order the '95 manuals and the '93 LT5 suppliment.

It's worth getting hold of the LT5 service video, I learnt so much from it.
Enjoy your Z :thumbsup:

You can also find manuals on Ebay from time to time.

I might add the training videos and training bookles that were put out by STG (Services Technology Group) You see the dub video out on Ebay all the time but if you ever wanted to see what was involved in cam timing and engine removal etc etc they are a great resource as well and adds weight to the helms series as a resource

Lowly?
hmmm....
I can think of many reasons why the '90 is the best year.
Lightest.
Quickest.
Most distinctly different than the base model Corvette of the year.
Only year with the black body side moulding.
And because the '90 was the first year of the King.
:worship:
Helms is where I got mine.

Hello from Switzerland,

Tom, you are right.
And, the '90 front end is different from all the others (1991-1995).
And, in 1990 they run the world record.
Okay, you may respond, that it was not exactly a '90 ZR-1,
but it could have been, if Chevrolet would not have given this
test car.

Have a good time,
