cheatr_small.gif Thunder Racing Custom Camshaft

"LS2 CheaTR" - 215/230 .629/.592 117 LSA. Off Idle-6800 RPM Power Band. Broad power range. Works well with stock exhaust manifolds and catalytic converters. Stock like idle. Minor tuning required on automatic transmission cars. Responds very well to nitrous. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended. Comp 921 Valve Springs are highly recommended.

that cam is known for being used on n/a f bodies who want to run stock mani's id go with someone with an even lift for intake and exhaust , when your forcing air in the cylinder you need just as much time if not more to get it out .

Thunder Racing Custom Camshaft

"TR Blower" - 214/230 .601/.579 117 LSA. Off Idle-6800 RPM Power Band. Broad power range. Different from our CheaTR with even less valve overlap for forced induction applications. Stock like idle. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended. Double valve springs and titanium retainers required for this cam. what do you recommend as a profile and manufacture to look for????

that seems more blower friendly , there are some good guys out there that can spec a cam just for you , try patrick G on ls1tech.com or call futral motorsports i have bought a few cams from them .

 

im running a 216/224 56x/58x 114+3 lsa and it doesent bleed to much boost but im spinning the hell out of my t trim vortech . and making only 15 psi with 9.2- 1 cr. with a stock motor it will take less boost to make power you just have a fine line to work with . id have someone spec you a custom cam . just let them know you want an aggressive street/strip cam .
