In the April issue of Car Craft (Yes, April 2007) they take a junkyard Gen3 6.0L (364 CI) truck engine, added a GMPP carb manifold with a 750 Holley, mild GMPP cam, MSD ignition and long tube headers.
The end result was 480 HP and 450 ft-lbf for $3775.
I've been looking at the Gen3 LS1 engines but have found them to be somewhat expensive and often abused.
The Vortec 5300 (LM7) is a V8 truck engine (5.3L 323 CI.) based on the Gen3 small-block V8. The LM7 is a very common junkyard motor so it is much less expensive than the LS1.
Using the concept from the Car Craft article I came up with this engine idea:
$540 Vortec 5.3L (323 CI) LM7 Engine, low milage junk yard unit
$690 Edelbrock Performer LS1 Intake Manifold Kit with MSD ignition
$266 Edelbrock Performer 600 cfm 4-Barrel carb
$300 Edelbrock Performer RPM Hydraulic Roller Camshaft
$250 Crane Valve Springs, retainers and cups
$370 Hooker Super Competition Block Hugger Headers
$ 84 Gaskets, Oil, filter
$2500 total
A similar setup on a 5.7L block with an 800 cfm carb pulled 410 HP.
Does this sound like a good swap engine for my street driven 280Z?
Thanks for any help!
