ok i am building a 355 with tfs heads 23 degree heads, and a converted lt1 intake..... what cam should i go with i called comp and the are tellin me a 12-268-4 but i want it so lope a bit.... and i am not a roller or i would go with an lt4 cam? so please guys help .... noticed a few with the lpe cams... how do yall like them.... please help......this is like the last thing i need to get my motor together... and comp is being hard headed and will not give me another cam choice that "lopes".... thanks guys

 

that comp 224/230 would lope nicely i'd imagine. i got a friend with a 227/233 in his LT1 (.565 lift intake, cant remember the exhaust) and it sounds like it is about to eat somebody, but then it is on a 111 LSA. Get the 268 and let me know how it does because you EXACT setup is what I want to do in my truck . I'm thinkin it should be very nice and might actually put my hooker supercomps to work for once! I am proud of everything on my truck except what is between the intake and the headers

 

yea i would like to get a cam with a 112 lobe sep but couldnt find one in the 268 series...... but i really wanted the lt4 hot cam... but dont wannata roller the motor.....

 

I think what you want is a cam with an LSA of 112*. That LSA will lope a bit, but still be friendly enough with the ECM. If you go with a 110* LSA, the ECM wll hunt for idle RPM and maybe give you error codes. An LSA of 114* (like I have) is very ECM friendly and will idle dead steady.

Look at Comp Cams on line catalog for part# 07-502-8 (grind# 269HR-12) and part# 07-503-8 (grind# 276HR-12).

 

both of those cams u suggested are a roller cam which i do not have i have a normal flat tappet cam....non roller
