OK you 460 experts an ol racer needs some help.I have a 467 BBF that will have dove heads that have been reworked, a TCI 5500 Stall, 4.88 rear gear and a 1.76 glide. I have a small cam i.e.....270@50, .580 lift. I don't plan to turn this engine more than about 6500 and leave the line around 3800. I don't think I need that much stall. What do you suggest? 4000 or 4500? Thanks in advance. Russ Hood

I'm no expert, but I'll throw my 2 cents in. I don't think it will be very happy with that cam. 270 @ .050 is not going to make good torque, if you plan to limit it to 6500 and leave under 4000 then you're going to need for it to make good torque. Also, .580 lift is nothing in a 460. The cam that I just took out of mine is a flat tappet with 253/260 @ .050 around .630/.650 lift on a 108 center. It absolutely quit pulling at 7000 rpm but made a ton of power between 3000 and 6500. I used it with a 5000 stall convertor in a 3520lb car. The cam that I'm running now is also a flat tappet with 264/268 @ .050 .650/.680 lift on a 112 center. This stick pulls right past 6500 and keeps making good power until 7000-7200. I also run a 5000 stall convertor with it at 3470 lbs. In short, I think the cam is more of a problem to your projected combo than the convertor. Just my 2 cents for what it's worth. ------------------ Butch 460 powered 1967 Comet Cyclone 10.27 @ 129.997 Butcher's Home Page "Friends don't let friends drive Chevys"

Thanks Butch, Guess I need to get a cam. The one I have was donated to the cause. After you spend $$$ and blow a cleveland after 11 passes it gets expensive. Thanks again for the info. Russ Hood

I understand expensive, I blew up a ton of FE stuff before I finally switched to the 460. I've still got the cam and lifters if your interested. I'm not positive on the lift but I'm pretty sure it was .630/.650, might be less but it's definately .620 or better. Duration is 285/293 @.020 and 253/260 @ .050 on a 108. I've got the lifters that I ran on it also, I ran 140-145lbs seat pressure with 360-380lbs over the nose. I got it for $100.00 from a friend of mine in Arizona who had run it on the dyno. I ran it for 4 passes before I burnt a piston and changed the combination. If you want it, I'll give it to you for $100.00 with the lifters. ------------------ Butch 460 powered 1967 Comet Cyclone 10.27 @ 129.997 Butcher's Home Page "Friends don't let friends drive Chevys"

Thanks, but I'm done with the FE stuff too. I still have the cam and lifters for mine and the rockers I'll use on the 460. I have a couple of people who want my intake and heads off the cleveland. I think I'll be bartering for some BB stuff for my car! Thanks,
Russ

I'm confused....The cam I am refering to is out of my 460, I went with a bigger grind when I went through the motor last time. I was just offering it to you because it's more geared to the rpm range you said you wanted to run and you said "guess I need to get a cam". I'm not trying to sell you any FE (427/428)or Cleveland parts. ------------------ Butch 460 powered 1967 Comet Cyclone 10.27 @ 129.997 Butcher's Home Page "Friends don't let friends drive Chevys"

Cam we just pulled out was Comp Cams 294/304 adv - 256/266 @ .050 with .589"/.615" lift on 108 degree lobe sep angle.Motor made 650 ft/lb @ 4250 and 645 HP @ 6250 - did not work above 6400rpm. Car always laid down on end - thought it was lack of heads, now figure it was cam - guess they were serious when they said 6500 limit! As we go thru the eyes at about 6900, elected to change cam. Went to Crane 302/312 adv - 266/276 @ .050 with .603"/.624" lift. With our setup we would have to cut the pistons if wanted more lift. This cam is good to 7400. So - Butch's cam sounds good to me, as long as you can keep the rpm down. Probably the 4500 stall would be better, ours was 5000.

If you run some mid to high seat pressure on the valve springs be sure to used two pins on the cam, a single pin will not last long. BUDDY THOMAS

I have never had a problem with a single stock pin with a solid cam.... but with the roller i busted one which did the valvetrain no kind of good

Butch, Do you think I can still use the 5500 convertor? Thanks, Russ

I would still use that convertor, remember, you still do not really have a "first" gear. So long as your shift point is 1000 rpm over the stall flash, you will be ok.And I have never had a problem with a single pin in the cam, not even in my roller stuff. Just my opinion.

I think I'd try it before buying another one....especially if the car is light.

Butch, Thanks, that was my thoughts also. I'm gonna send the convertor to Kenny Ford at PTC and have the tranny gone through before I start putting everything back together. Russ
