I have a pretty stock 292 going into a 55 Tbird. ECZ G heads with a 57 Tbird holley 4 barrel manifold. Will be getting headers and a 4r70w trans behind it. Just seeing if anybody has run this cam before. Listed specs are:
Adv duration 255 .050 duration 220 .463 lift 110 lobe separation 106 intake centerline
Does it sound like a decent cam for a weekend cruiser street car?
Thanks Paul

Looks good, but I'd think Howard would want his camshaft back by now.

I had considered this cam and the same cam/w 112 LSA. I contacted Howard's several times, requesting a cam card, but got no reply. I also posted the request on Summit, but no reply. I'm not likely to purchase products from anyone who refuses to answer simple questions about their products. I ended up buying Schneider Racing's 258F cam. Jerry was very helpful. Ted likes Isky, and Tim McMaster likes Oregon Cams. Someone on VTCI is putting a Clay Smith cam/w 220 degrees duration @ .050 in his F Bird. By the way Howard's Cams was sold years ago. The founder is long gone.

Take a look at the ISKY 301444 cam. I have a 301333 in my Tbird with a manual transmission. It's a great cam, but it may be a little too bumpy for your taste.

If your car has/will have power brakes, you'll probably want a wider (112) LSA. I would also keep duration @ .050 at/below 220 degrees. The OEM cam, I believe, had 197 degrees @ .050/w 113 LSA.

Correction! The Clay Smith cam that I mentioned earlier is going into an E-code, not an F.

Phil, the 301333 is "bumpy?" Even with 228 degrees duration @ .050, I would have thought that the 112 LSA would smooth things out a bit. The guy/w the E-code also had a cam with 228 duration @ .050 before rebuild. I don't recall the LSA, He said he liked the lope, but thought it was too much cam. He wanted the sound but not the manners. I think it's common for people to over-cam street cars. Bigger is not always better.

I was originally going with a c4 tranny so I put a 3.10 gear in the rear. The 4r70w has a much lower 1st and 2nd than the c4. Both have a 1 to 1 third, and the 4r70 has a .70 overdrive. The bird has a good bit bigger set of rear tires, so I will have to see what it drives like. May have to put in more gear, I also have a 3.89 gear set. Will probably go with a dual reservoir power master cylinder. I have the wilwood 11 inch disc kit up front, and big 11 rear drums. I don't mind some lope in the cam, put I don't want it to be an undrivable race car with the automatic.

Ogasman, I have a C4/w Dynamic Racing Transmission's wide-ratio gear set/w 2.90 1st and 1.60 2nd. I have 2.72 gears in rear. If I had overdrive, I would have left the stock 3.31 gears. your setup will be fine/w 220 @ .050 duration, but I would prefer 3.55/w OD. My tires are 215/70r15 that are 26.9" diameter. I'm looking at approximately 2200 rpm @ 65 mph. Your cruise rpm should be within cam range; in my case, the latter is 1800-5000 rpm. My knowledge of your transmission is limited, but it probably has a lock-up torque converter, like the AOD. You probably want to stick with stock converter/stock stall speed. I have a Hughes converter/w advertised stall speed of 2000 rpm, but their ratings are based on big-block applications. Actual stall speed behind a Y-block is probably 1600-1800 rpm. With my gears, a higher stall speed could result in slippage if cruise rpm lower than stall speed. For comparison purposes, cruise rpm for Fordomatic and 3.31 gears is 2800-3000 rpm. 2200 is good.
There are RPM calculators online, like Strange. You can play with gear ratios, tire size, etc. to find desired combination.

A little over stock 292 with a CruiseOmatic an 8.8 with 2.74 is perfect in my 56 Victoria and it’s heavier. I wouldn’t change anything. Any 3 speed OD or not is a good thing and makes the old FordO cars a pleasure to drive. I did drive it with the 3.31’s for a few months after the trans swap but knew I was going to change it.
