The Texas Speed Cleetus McFarland Bald Eagle LS3 Boost Camshaft is the rectangular-port version of the grind Cleetus McFarland runs in Leroy, his C5 Corvette. Texas Speed recommends it for supercharged 6.0L and 6.2L LS engines with rectangular-port heads, and notes it can also be ordered for naturally aspirated setups where a little more chop is wanted.
At 229/242 duration, .600" lift, a 115 degree lobe separation angle and 111 degree intake centerline, Texas Speed describes the Bald Eagle as easy to tune with a nice lope at idle and estimates a gain of 80 or more horsepower. Upgraded valve springs are required, with the TSP dual spring kit recommended, and automatics need a 2,800 rpm or higher stall converter. The cam is supplied only on a 3-bolt core, so single-bolt engines need a 3-bolt upper timing sprocket and ARP cam bolt kit, and any factory DOD/AFM and VVT must be removed.

FAQ
What engines does the Texas Speed Bald Eagle LS3 Boost Cam fit?
It is ground for 6.0L and 6.2L LS engines with rectangular-port cylinder heads, such as the LS3, L99 and L92, in supercharged applications. Texas Speed also sells a cathedral-port Bald Eagle for LS1, LS2 and LS6 engines.
Does the Bald Eagle LS3 cam fit a single-bolt camshaft engine?
Only with a conversion. The Bald Eagle is supplied on a 3-bolt core, so an engine that came with a single-bolt camshaft needs a 3-bolt upper timing sprocket and an ARP cam bolt kit, both of which Texas Speed offers.
Do I need to delete DOD/AFM and VVT to run this cam?
Yes. Texas Speed states that factory DOD/AFM and VVT must be removed before installing the Bald Eagle LS3 Boost Camshaft on engines that were equipped with them, such as the L99 and many 6.2L truck engines.
What valve springs and converter does the Bald Eagle LS3 cam require?
Upgraded springs are required, and Texas Speed recommends its TSP dual spring kit with PAC Racing polished dual springs, titanium retainers, seats and seals. Automatic transmission vehicles need at least a 2,800 rpm stall converter.
How much power does the Bald Eagle LS3 Boost Cam add?
Texas Speed estimates a gain of 80 or more horsepower from the Bald Eagle LS3 camshaft. Actual gains depend on the supercharger, boost level, cylinder heads and tuning.
Can the Bald Eagle LS3 cam be daily driven?
Texas Speed says the cam can be daily driven without issue once properly tuned, with a nice lope at idle and an operating range of 2,000 to 6,800 rpm.
