The Texas Speed Cleetus McFarland Bald Eagle LS1/LS2 N/A Camshaft is the naturally aspirated version of the grind Cleetus McFarland runs in Leroy, his C5 Corvette. It is intended for cathedral-port LS engines without a supercharger, with 5.7L and 6.0L engines listed as the best fit, and it carries a little more chop at idle than the boosted Bald Eagle. Texas Speed calls it an easy camshaft to tune with a nice lope at idle.
Texas Speed estimates a gain of 50 to 55 or more horsepower and recommends a compression ratio of 10.1:1 or higher. Automatic vehicles need a stall converter with at least a 2,800 rpm stall speed. A rear gear change is not required, though a 3.23 or steeper gear is recommended for maximum performance. The cam can run on PAC Racing 1219 single beehive springs or the TSP .660" dual spring kit, and a custom tune is required after installation.

FAQ
What engines does the Texas Speed Bald Eagle LS1/LS2 N/A cam fit?
It fits cathedral-port LS engines such as the LS1, LS6 and LS2 in 1997 to 2007 Corvettes, 1998 to 2002 Camaros and Firebirds, 2004 to 2006 GTOs and cathedral-port GM trucks. Texas Speed lists 5.7L and 6.0L as the best suited engines.
What is the difference between the N/A and supercharged Bald Eagle cams?
This naturally aspirated version is for engines without a supercharger and has a bit more chop at idle. The boosted Bald Eagle is the version Cleetus McFarland runs in Leroy with a blower.
Do I need a stall converter with the Bald Eagle N/A cam?
Yes, in an automatic vehicle. Texas Speed requires a torque converter with a minimum 2,800 rpm stall speed. A rear gear change is not required, but a 3.23 or steeper ratio is recommended for maximum performance.
Which valve springs work with the Bald Eagle N/A camshaft?
Upgraded springs are required. Texas Speed says the cam can be run on PAC Racing 1219 single beehive springs or on the TSP dual spring kit with PAC Racing polished dual springs, titanium retainers, seats and seals.
Can the Bald Eagle N/A cam be daily driven?
Yes. Texas Speed describes it as a great daily driver camshaft once properly tuned, with a mild chop at idle and an operating range of 2,000 to 6,600 rpm.
Is tuning required after installing this camshaft?
Yes. A custom tune is required after any camshaft swap so the engine idles, starts and runs correctly with the new profile. Texas Speed states tuning is needed in both automatic and manual applications.
