LS3 Conversion (76 Corvette)

Anything, used, more than $3500, it’s time to go new.

Leaning toward the Hot Cam LS3 built engine. 480HP, 473lb.-ft.
Chevrolet Performance LS376/480 495HP Hot Cammed LS3
https://www.gmperformancemotor.com/parts/19369333.html

Powerplants I will consider, depending on price:
LS1 Aluminum 346ci 5.7L 1998-2002 Camaro, 305-315hp 1997-2004 Corvette, 2004-2005 GTO 345-350hp
LS2 Aluminum 368ci 6.0L 2005-2007 Corvette/ 2005-2006 GTO 400hp
LS3 Aluminum 381ci 6.2L 2008-2009 Corvette 435hp
LS6 Aluminum 346ci 5.7L 2001-2004 Z06 Corvette 405hp
L92 Aluminum 381ci 6.2L 2008-2009 Silverado Maxx, Denali, Escalade 403hp. This engine shares the same block as the LS3.

A brief summary of some differences.
1998
Had differnet casting heads which had perimeter bolts and valve covers.
Ignition coils were mounted to the valve covers one at a time.
1998-1999 LS1 cars had a smaller throttle body cam, which caused the throttle to open to WOT faster than 2000+ cars
1998 cars had 28 lb fuel injectors from the factory
1998-2000 cars had a larger cam than the 01-02 cars
1998-1999 cars had more restrictive exhaust manifolds
1998-2000 cars had an LS1 intake with EGR
1998 only LS1 blocks had a much smaller cylinder sleeve that only tolerated a .005″ hone
1998 only cars had a different PCV system with the PCV valve located above the passenger side valve cover
1998 most cars did not have an idle adjustment screw on the throttle body. Some 98 cars do have the idle throttle stop set screws.
1998 cars have a completely different PCM from 99+ cars
A production shortage of F-body cams caused the use of a C5 cam to be installed in F-body LS1s for a very short time

1999
1999-2000 cars switched to 26 lb fuel injectors
Cylinder heads and valve covers redesigned to have center bolts instead of perimeter bolts. Other than that, the heads were the same.
Redesigned cylinder sleeves that allowed for a small bore, up from .005″ in 1998 models.
1999 cars continued the LS1 intake with EGR provisions
1999 cars continued more restrictive exhaust manifolds and larger cam
1999-02 cars had a different PCV system with the valve located to the side of the intake manifold

2000
Redesigned exhaust manifolds for new emissions standard actually flowed better and created a little more HP.
2000 continued use of LS1 Intake, EGR, smaller cam, and 26 lb fuel injectors
Throttle body cam was increased in size to slow the speed at which the car reaches WOT
Starting 2000 intake lids contained a seperate breather filter

2001
A small percentage of 2001 and 2002 LS1s actually had LS6 blocks which had a different part number and a darker metal cast
Starting 2001, all LS1s came with an LS6 intake manifold without an EGR system
Advertised HP output was changed from 305 to 310 on base LS1s and from 320 to 325 on WS6s and SSs
2001-02 cars have a smaller cam from the Vortec truck engines to increase low end torque
2001-02 cars had 28 lb fuel injectors like the 98 cars (albeit different part numbers)

2002 – Last year of the F-body
2002 LS1 head gaskets redesigned. The new ones are a pressed metal, as opposed to the graphite ones and are no longer specific to the side of the car theyre installed on
2002 cars continued with the LS6 intake, 28 lb fuel inectors and smaller truck cam
2002 continued the use of an LS6 block in some LS1 F-bodies
A factory supported optional 345 HP option could be ordered from SLP

A Note to Eckler’s Corvette

I wanted to contact you and say I am far from happy about the quality of the fiberglass parts I received, order # 11184560. Specifically with the front and rear bumper (Part # 33662 and 10341 respectively).

While I expected some fitment issues since this is a 30+ year old car, I did NOT expect the multiple thin spots and bubbles just under the gel coat. This has lead to extensive body work on, what should have been, install and go parts.

Here, we have an area that was less than a 1/16th of an inch thick. An area right next to the mounting surface.
http://gallery.kulish.com/main.php?g2_itemId=5315

Here is another thin spot that was sanded through but on the front this time.
http://gallery.kulish.com/main.php?g2_itemId=5345

And these two were bubbles right under the gel coat in the rear lamp buckets.
http://gallery.kulish.com/main.php?g2_itemId=5126
http://gallery.kulish.com/main.php?g2_itemId=5123

2 out of 3 fiberglass parts on this order now require additional shop time to correct.
Is it possible to get some sort of partial refund due to the amount of labor it will require to fix these manufacturer defects?

This is why I did not order my hood from you nor can I recommend you as a supplier if this is the quality of work you provide. Regardless of any refund provided by you.
