New purchase came with heads/cam Hey all
Bought a 99 Z28 convertible last month. 100,000 miles. Black. SLP intake/exhaust. SS wheels. 275 squared stance. C7 brakes. Good starting point.
The previous owner bought a set of 243 heads and a stock cam from a C5 Z06. Low mileage on both when pulled.
Sent the heads out, they're good. just looking for thoughts. I figured i'd use them. Add an Ls6 intake manifold.
Headers and y-pipe. Have her tuned. Im not a drag racer by any means and im not one for crazy power or going for big power.
I figure it would be a decent jump from what it is now. Id imagine the cam will make for a nice manored drive. Add a bit of sound.
Ultimately its a sunday cruiser for the wife and I. Just want a little more kick. What kind of gains are those with experience thinking?
it came with a set of yellow springs for the heads as well. Id imagine tuning with factory z06 heads, cam and intake would be fairly easy but i really dont know.
Ultimately looking for input. what would be a good parts list to gather before putting it all together. Its a 4l60 car too.

If you figure the factory numbers, 1999 F bomb motor was 325 at the crank, although closer to 350 in realsies. C5z was 405 at the crank and truly one of the best factory engines gm made. I think you make a great choice to take the 243 heads,bowl blend, valve job, no porting, z06 cam. Easy to tune, easy to drive. If you do not already have the ls6 intake, consider a used fast 90 or 92 for another 15-25 powers.

If you can find an LS6 intake go for it and use thinner head gaskets @ 0.041 if you can find a set. That will increase your compression and give a bump in torque.
