A little help with cam selection without fly cutting I'm wanting to get some power out of my '98 Camaro LS1 A4. It is not going to be a street car, but I still want enough drivability to drive it about 3-4 miles every once in a while to get to the "Racing Spot". As of right now, I believe it is all stock except the transparent lid that is on it. I bought a used set of stock 243's that I plan on having ported and polished and a set of 1 7/8" headers so far, next I will be buying an ls6 intake, and then the cam kit, and a stall. What cam would be a good choice without having to fly cut the pistons?
I've read that the MS3/4 both clear on a stock 243 head, but wouldn't that be to much cam for my heads an intake? I just want to be fast...lol.

The repeatability of CNC is its main attraction. Ports on one head will be IDENTICAL to those done dozens later. A guy hand does a killer port, then digitizes it, and it can be repeated over and over.

The larger 3 and 4 stages can make power, but there’s and expense in driveability and Tunability. The Summit Pro Ls Stage two will be an absolute monster and there are a free other inexpensive things that will make big gains. Easy to tune. Easy to drive. Rapid trade offs soon after with your package as it sits or will be soon. We have the bigger twos and threes and even 4 that will clear, but your tuner will be the best judge after looking at our valve event numbers.

Yes, you should always check Piston to valve, but even the largest stage 4 is designed to clear a factory flat top. It would probably be a good idea to run a .045" head gasket to maintain .036in. minimum piston to head. Any closer and there's a chance of the piston hitting the head.

The Texas Speed tsunami will make just as much power as the ms3/4 and work great. Im not sure any other cams can hold a candle to it if you want brutal tire shredding power and great mid range also.

Yes, the 1218's are a great match.
