[69Custom]

I have a '69 Custom S with the original XS block 350. I swapped out the heads with some 670s and put on new intake for a quadrajet (was running a 2barrel before). I have the stock cam in it, but would like something to produce some more power.

What is a good option for a better cam for me? Also, do you know what size pushrods I need for it?

Maybe someone can tell me what camshaft came in the '69 400 RAIII motor?

Assuming your car is an automatic, I would go with a cam grind similar
to the specs on a ram air 3 automatic 400 engine. If you want a perfect idle, go
with the 067 cam grind. If you want a little more cam go with the 068 grind. My car
is an automatic 455 engine with the 067 grind and I love it. It idles perfect and will
burn rubber for blocks if you nail it. All the GTO's I get in my shop come in with too much
camshaft and they idle terribly and won't get out of their own way when you punch it.
Unless you are a drag racer, don't go wilder than the 068 grind on the street. I had a ram
air IV cam in my car back in the 90's and I hated it. It idled like crap and the gas mileage
was horrendous.

I do have an automatic. I have th400 in it. I definitely want a nice idle and want it responsive when I punch it. It's not for racing though. Just a nice cruiser with some power when I want it. I'll look into an 067. Thanks!

What was the stock cam for the 350HO? I want to say it was a 067 or 068.

My 350 is not the HO version I don't think. According to the books it was rated at 265 HP with a two barrel.

Right, I was just thinking aloud that the stock cam for the HO might be a good choice given your heads and 4bbl manifold. Might be a good idea to add some Ram Air exhaust manifolds while you are at it.

Good call on the manifolds. I got a set on it now. I don't know why I didn't swap the cam when I did all that work. I wish I had. I'm not sure if I should put new pushrods in the a new cam. I'm thinking I should. But I'm not sure what size.

New lifters? Yes. New pushrods? Not necessarily. If they're straight (roll each one on a glass pane) and the ends aren't chewed up, I would clean them and re-use them. One possible problem you could run into would be that the lifters that you use with your new cam are configured differently than the ones on there now. Example, if the lifter cup where the pushrod sits is 1/4" deeper than the cup on your existing lifters, it may throw off your geometry a bit but likely not enough to make a difference.

Good luck.

For 1969 the 068 cam was used for the manual trans 350 HO and 067 for the auto trans application.

In '68 the 350 HO used the 067 and 066 cams respectively.
