Camshaft Choices
TSP Cathedral Heads Stage 1 (224R)Cam Specs: 224/224 .600/.600 112LSA
The Stage 1 camshafts use lobes that are designed to be both beehive & double valve spring friendly. The 112LSA helps to bring the camshafts powerband lower in the rpm band.The lower LSA also creates a slightly rougher idle. The Stage 1 camshaft is without a doubt one of the most popular camshafts we offer for the LS1 engines.It has awesome drivability while making a solid 40+ rear wheel horsepower gains! For customers looking for a smaller camshaft that packs a big punch, the Stage 1 camshaft is pretty hard to beat!

The 228R camshaft is a very streetable camshaft that makes approximately 5-7 more horsepower over our 224R camshaft. Dyno testing has shown the 228R camshaft to make a solid 45-50rwhp gains. The 228R camshaft is large enough that we recommend a larger than stock stall converter in automatic cars. Tuning will also be required in both automatic & manual applications.

Dyno testing has shown the Stage 2 camshaft to make a solid 50-55 RWHP gains with all other supporting bolt-on modifications in place.

Cleetus McFarland "Bald Eagle" LS1/LS2 N/A Cam Specs: 227/234 .600"/.600" 111 LSA 109 ICL
Purchase the naturally aspirated version of the camshaft that Cleetus McFarland is running in "Leroy", his savage C5 Corvette! The naturally aspirated version of the Bald Eagle camshaft is a great choice for engines running cathedral-port cylinder heads and not running a supercharger. It will have a little bit more chop at idle vs. the boosted version of the Bald Eagle cam. It comes with a large dose of 'murica and full of bald eagles! It is an easy camshaft to tune and has a nice lope at idle. Automatic-equipped vehicles will require a minimum of a 2,800 RPM stall speed torque converter. This cam can easily be daily driven with zero issues once tuned properly. The Bald Eagle cam can be run with either the PAC Racing 1219 single beehive valve springs or our TSP dual spring kit that includes PAC Racing polished dual valve springs, titanium retainers, spring seats, and valve seals.

Dyno testing has shown the Torquer V2 camshaft to make a solid 50-55 RWHP gains!

TSP Cathedral Heads Stage 3 ( Torquer v4) Cam Specs: 231/234 .629"/.615" 111 LSA
The Stage 3 (Torquer v4) camshaft features a more aggressive intake lobe that requires a good double valve spring kit. For customers looking for a quality double valve spring kit, we recommend the PAC .660" double spring kits. The new more aggressive intake lobes & small changes to the camshaft design has allowed us to create more peak power while bringing power in earlier than the Torquer V2. With the Stage 3 camshaft we typically recommend the customer have at least a 3200-rpm stall converter for automatic cars. Tuning will also be required in both automatic & manual applications.
