I'm not looking to track my car but since I've chipped the edge if the cam gear, I may just replace it along with the lifters. Looking for something that will maintain what little fuel economy these cars get. I doubt I can get a NOS one so I'm open for suggestions. Only mods are Champion intake, GN1 SLIC, alky and chip, 3' ATR exhaust. I want a smoooooth idling camshaft. Thanks in advance for your advice.
Mildest flat tappet cam avail. for the GN?

With over 20 years of cam selections, the best choice for you is the 206/206 flat tappet.
We have installed over 100 of these and it sounds and acts like a stocker, except a little more mid-range torque and HP.
Just as a side note, only 2 of the ever wiped a lobe, and both owners used Mobil I.

206/206 or 204/214 -both good choices
I used to run the old poston's 202/202 back in the day with stock set-up..
Lunati 200/200 was another good old cam..

Check the LSA too. My 210/210 on a 110 biller roller is not exactly smooth at idle.
Ok I'm looking at the 206/206 flat tappet cam. Can I use new GM lifters or is there something better? Again, not gonna track/race the car so looking for dependability/longevity. Will this wipe out my fuel mileage as it will be considered a DD even though it may not. This is the only 206/206 cam I found. Turbo V6, 231H.440"-206'/.440"-206',112', TA_V260H | TAPerformance.com
Cottons also sells the comp cams 206/206 flat tappet kit. I have this in my clone. Seems like a lot of people recommended this for a stockish setup. There is also a 206/206 roller cam you see in a lot of faster combos, but this is usually the high lift cam like the one Weber sells.

My TTA has the 206/206 flat tappet and its pretty mild, idles like crap with a stock computer but runs like a dream with a Turbo Tweak chip
I'll have to see what chip I have. I thought these idled smooth?
I dont have a 206/206 cam card handy but id imagine there are different grinds with the same duration. Id want a cam with more seperation and around .450 total lift with 1.55 rockers to minimize the overlap time as much as possible. The more vacuum the engine has at a given rpm the less overlap the cam has. More duration does not always mean more overlap. If you look at the cam lobes a company like comp offers im sure you could select something that is very very close to stock and have them ground. Roller or not. Unfortuately i dont have the stock cam specs handy. Im sure its been cam doctored before. Maybe someone else has the #'s
So what are your thoughts on the 208/208 flat tappet cam?

Well I wound up getting TA's 206/206 and lifters. It was hard not to order up a set of aluminum heads to go with my intake while on the phone.:redface:

I forgot to mention, when I ordered the cam/lifters form TA, she advised me to buy a bottle of zinc additive they offer for cam breakin. {$18} so I did. Upon putting everthing back together I had planned on cleaning the oil pan and changing the oil along with ZDDPLUS. Should I combine ZDDPLUS with the breakin additive? Seems a bit overkill.
