relpy yes im shure its a 02 engine i have all the paper work the vin number it came out of i even have a paper from the factory build sheet and a carfax on the car it came from also. it came from a place i think its called lqs? or some thing like that. it onky has like 30k on it. so if the egr's are different does that mean that the exaust manifolds are off the old motor? is it a straight swap? i have the egr on the passenger side if the head.
also wheres the best place to look for the casting number?
thanks for the help guys

01s and 02s did not have egr and came factory equipped with an ls6 intake. I'm pretty sure whoever did the work would just replace the longblock. The accessories and intake were probably just swapped over. I don't think it is legal for them to remove any emissions equipment that your 98 came with.
Pre 01 Corvettes also came with the ls1 intake, but not the egr equipment. You can tell the difference between the ls1 and ls6 intakes by looking at the bottom of the intake. LS6 intakes have a flat bottom and no egr. LS1 intakes may or may not have egr and have a hump on the bottom.

reply well i got the car from a guy i know and he said it had a ls6 inake on it.when he had the new engine put in he said that he put the so called ls6 intake back on the new motor witch was a ls1 instead buy what you guys said.
i dont think he new the differance. so i have the 98 manifolds and intake?
the car is really strong and it made like 336 at the wheels.
the engine was a hole crate motor out of a wrecked ws6 [guy i got it from hit a big puddle in a thunder storm and hydrolocked the engine and the insurance replaced the engine]

Easiest place to see the casting number for the head is on the passenger side head, lower right, just below the oil fill and valve cover. If you want to check the casting number of the block it's on the driver's side, back of the left hand deck, above the transmission flange - you'll need a flashlight and inspection mirror.

reply well the casting # on the head is 241 so it is a o2 motor.i cant tell if the manifolds are stainless or not a magnet sticks to them. the they look a little shiny by the flange but i has the normal rusty .
also doesent some f bodys come with the ls6 block
how do i tell?

Would it make since to put an LS1 into an f-body, and then try and hook the rx7's emission equipment up to the LS1 motor? The 02' was setup as to not require an egr, and therefore is not required in his car. Sometimes when you swap a newer/different motor into an older car, the older emission hookups won't fit the newer motor. It would be stupid to require a newer motor to try to mate with older, outdated and less efficient emission equipment.
Many states don't even do a visual, but I was under the impression (from other's I've spoken with from CA) that they look to that emissions sticker to check for necessary equpitment. Perhaps they were mistaken?
Yeah, they do look for the emission sticker under the hood and check for the appropriate pieces. If they assumed it was a 98 and he didn't have proof, I'm sure they'd probably require egr. If he showed a smog ref his paperwork, then they'd hold him to the standards of an 02.
