Heads and Cam ???

[img]/phpBB/images/smiles/icon_smile.gif[/img]OK guys, I want to upgade my heads, but am still in the learning process about all this. I've seen good things said for the GT 40, and AR 165's. I want low end power, I guess, since my carb and intake are for top-end. I will also be going 350/355's on the rear, and I guess it should be first, but I don't really have a clue as to where to start, or what I need. If you have any ideas or comments, please feel free to speak your mind. Thanks

Is this a daily driver just looking for more power kind of deal? If I were just looking to wake up a 289 and had a bunch of other projects I wanted to do too, I'd probably lose the Performer for an RPM, then run the AFR 165s and something like the COMP XE268H, then the 3.50 gears. It depends on what you really want to do, though - if you think you're going to wind up still wanting more and have a sort of "some day" plan for it, your plan should probably reflect that in the beginning or you'll wind up spending a lot of money twice, from the front of the car all the way back. In that case, I'd just do the gears and figure out exactly what you eventually want from your engine and build that, even if it takes a while longer.

I guess my carb intake is better at high rpm's, I don't know what I'm trying to say exactly. When I got that combo, it was with a cam upgrade in mind, but I never thought to ask about the heads. Would some of the better 351 heads work OK??? For now, I will have to settle for the most I can get out of this and stay around stock. My next moter will be a stroked 351. Anyway, I guess the 270 cam and SOME kind of head will be put on there. I will get the gears first, sice I will have to get them anyway.

well first off, the carb and intake is perfectly suited for average, daily driver RPM. The performer intake is not much more than a stock replacment 4v intake. Its designed to work best between idle and about 4000 RPM. If you want a daily driver, pick a small cam. If you want it to still sound like it has authority, pick one with a tight lobe separation. something in the 110 will still give a small amount of chop to the idle.

My thoughts exactly. The problem you're going to run into is that you're probably going to find that you want to upgrade the rear to a 9" at some point, so the money you spend on the gears will be down the tubes, and if you go with a 351, especially a stroker, the heads, cam, etc, will be sunk too. (Trust me, I've been down that road myself [img]/phpBB/images/smiles/icon_lol.gif[/img])

If you can . . . maybe find a 351W now in decent condition, and put AFR 185s or even 205s and the XE274 if you're sure you're going to stroke it, and go from there? Not to say you can't build a screamer 289, but it doesn't sound like that's the route you want to go - you'll get better street manners with more cubes to get you where you want to be.

I see what you guys mean, might as well just do this one with what I got. The 289 will get on, but you know how it is, what can I do to get MORE hp is always in the back of my mind. So, if I go wityh a 270 cam, and some AR 160's, the carb/intake combo would work against the rest of it??? Sorry, but I just want to be absolutely sure before I comit to someone about the order. Thanks for the time and info everyone.[img]/phpBB/images/smiles/icon_bow.gif[/img]

I really think you'd be happy with the AFR165s, the XE268 Comp cam, and a performer RPM intake. The carb might be enough . . . you'd have a responsive, mean sounding street machine that's not too tempermental.

EDIT: I should have added that you're not going to HATE that performer if it's not something you're going to be able to change just now - they get a lot of bad press, but I ran one on a 350 chebby years ago, in a BIG '56 Chevy body, with a 600 VS Holley, that ran low 13s, even breaking into the 12s.

[img]/phpBB/images/smiles/icon_biggrin.gif[/img] Thank you very much, that's what I'm shooting for. I don't want to be under the hood ALL the time.

For Cylinder heads look into the trick flow heads. They are just as good as the AFR 165s and cheaper. They will work great with that engine you have now and you will have tons of room to grow with them should you decide to later. Just send those suckers to Total Engine Airflow for a CNC porting job if you ever do the 351 stroker. I don't know if you could grow that much with the AFR 165's since they already have the CNC porting done to them, I have never seen any of the head porting places advertise any type of stage CNC porting programs for the AFR'S. You would probably have to buy a whole new set of heads if you went with the AFR 165's and you wanted a bigger badder engine later down the road.

[img]/phpBB/images/smiles/icon_smile.gif[/img] Thanks Eric, I'll check into the Trick Flows. I like saving money, even better if I am getting just as good a product, or better.[img]/phpBB/images/smiles/icon_razz.gif[/img]
