I opted for the TA 284-88H grind for my sbb.My plan called for 9.5:1 cr but I ended up with 9:1 because of my inhability to use the steel shim head gaskets with my heads.The reason I picked that cam was because it's very close to the TA 212 that everybody here seems to favor.The 284 cam has .010" less lift on the ex side than the 212 but it has more advertised duration in both the intake(+19*)and the ex.(+8*).Since my heads were only treated to a bowl clean up,I don't think that I'll benefit as much with the extra lift from the 212(.010") as with the added duration from the 288.I'm also restricted to stock manifolds,Y pipe,Cat,Y pipe and duals.I smoothed the manifolds as far back as my tools allowed and tweaked the rest to promote as free a path for the exhaust gases as I could and still be "legal" :Brow: .I guess that I'm betting the farm on the idea that the lower lift but increased duration of the 288 will help me to get rid of the exhaust(which is the weakest part of my set up after the weight issue) in a more efficient manner than the 212.I can always do a cam swap if it doesn't work as I expected :bglasses: .I do consider both these cams to be in the upper mild scale and if given the chance to build a 9.5-10:1cr engine I would like something like the TA C113. What do you have in mind? :bglasses:
I'm using the Poston 114 for its good street manners and torque. I haven't changed it for the turbo setup but probably will go with a hotter cam on the next motor.
I am running a GS111 cam Works well with my ported heads and I got a great deal on a cam and lifter setup. :TU:
I am running the TA212 right now, because of it's mild street manners, it has a very slight lope to it and still gets great gas mileage. I am moving very soon (hopefully before it snows) to a TA413 cam and going with Poston headers, PAE ported heads and 2.5" mandrel exhaust. Also jumping from 3.23 gears to 3.90 posi. Hoping my 60' times will greatly decrease!
I chose the TA 212 because it was basically the biggest i could go with a stock convertor and 2.56 gears.But since then the heads have been ported and I stepped up to a TA Intake.I'll be going with a bigger cam and I have a set of 3.42's I'll be putting in along with a higher stall convertor.I'll be happy if I can get it to the low 14's or high 13's some day.It's still my weekend cruiser and car for road trips so I want to keep it fairly highway friendly.
I use the GS club Pop Mech cam 230-245, 507 502 lift 116 lc. I had the TA 510 cam in at one time 255-265 576 lift 110 lc, but I think I needed a very loose 3500 stall conv. and about 456 gears to get this baby to work, I only had 373 gears. I would like to get something in between the TA 413 cam an the TA 510 but don't know what to use. I am using a 125 shot of Nitrous so I would like to match up with that. But I would like it to sound as good as the TA 510 sounded as it sounded bad ass. The 510 would probably rev to 6500 rpm.

246/260@.50 .578/.600 112LC Figured this was a good grind for a boosted setup. Worked well above 5k rpm until around 6800 when the exhaust couldn't handle the volume. Have some other grinds we will be trying.
If your going to stay with a small shot of nitrous(under 200) then look at 108-110 LC on a cam. It will make a TON of difference on you midrange torque where you need it on that 350. It will also make the nitrous seem stronger but will limit you to a smaller shot. You need a BIG shot of nitrous to make that 116 LC to work right. You can stay with that same cam but just tighten up the LC some. :TU:
Kenne-Bell=KB Main interest is the v6 Turbo motors but they have been doing v8 stuff for the Buicks along time.
I'm using the TA290-94H cam in this build, previous build have had a couple of Torque Tech cams, 210-220 duration with .480/.490 lift was perfect in a stock rebuild, added some nice power and worked well with all stock components. I also tried a 230-245 duration .49x/.51x lift but found I didn't have enough converter or gear. The TA290-94H cam has been a good compromise with my stock 3.23 gear and 2200 converter, which I like for street driving. It's also motored me to a 13.56@99.7 in the 1/4 which isn't too shabby for a stock intake, quadrajet, points ignition, with headers 350!
I'd say that cam has worked well for you with all those stock parts still in place. I'm looking to use the same cam on my 350, but with a T/A 350 stage 1 intake, 800 cfm carb, headers and electronic inginition, as well as a ram air box set up. I'm also going to try and have Jim Burek @ PAE performance rework the heads for better flow. My goal is to go under 13.5 in 1/4 mile. Are you running a posi rear end? What tranny?
Yes, a stock GM posi from a '72 Skylark. The tranny is a T350, also from a '72, with a Turbo Action shift kit. The converter is a Daaco, nothing fancy one step above stock in the catalog. I did have an HEI and TA intake on the car and it ran the same times. I liked racing in the Pure Stock X (modified which allows headers) class at a local track so I dumped the intake and HEI and the car still runs the same times. The heads have had some clean-up work done on them, as everyone says the power is in the heads!!
