I agree with Tusky that the TBSS intake and 799/243 heads are the way to go on a LM7. The TBSS intake is the best stock intake manifold for a cathedral port head and the 799/243 head flows more air than the factory castings.
We need to know more info such as what transmission, rear gear, vehicle weight, tire size, usage of the vehicle etc.

Hey guys I'm looking to do something similar. I have a 1995 z28 camaro looking to do a 5.3 swap. The lt1 was junk and pulled that out but still have the 4l60e tranny and pacesetter headers. Will these headers fit the 5.3? Also what top end route should I go with and what intakes will fit? Sorry for the stupid questions.

I agree with you Martin. All that matters ALOT when dialing in a camshaft for a specific vehicle and it's application.
The reason I said the 210/218 cam I because it was proven on the engine dyno by Richard Holdener. Itll be the quick " go to" choice. That cam made great torque and power EVERYWHERE in the powerband while the other two cams that was tested gave a tradeoff so to speak.
The other two cams was tested was a 206 duration and the biggest one been a 224 duration cam which made the little 5.3 hurt below the 4500 rpm mark.

Martin, the lift was 551 and the LSA was a 116 if I can remember. Here is the link to that specific article I'm referring too.

You'll clearly see the 206 cam was a torquey little cam but felt off in the upper rpm range. The 224 cam which was the biggest cam tested made the highest peak power but it hurt the low end grunt of the motor. The 210/218 cam from crane just delivered great torque and power through the entire power band and still hung on up top strong well.
