Hi all, I was wondering if you guys can help me out with a cam selection for my Stage 1 rebuild. I am looking to have a car in the 11's when I'm done but I was wondering what is the best cam for me. The car will be mostly a street everyday driver. The cams are as follows: TA Street Intimidator GSCA Hemi Killer TA 298H (Hemi Destroyer) Lunati 238/248 TA Street Dominator TA 413 I will not be modifying the engine for higher revving so I will be shifting at 5500 RPM. Also does anyone out there have the ballpark prices on these cams?? I ordered a Catalogue from TA Performance a few weeks ago but have not yet received it and am curious of the prices. Also I was thinking of using a SP 1 intake is this a good choice and what is the price of it as well. Thanks for all your help, Gerald
413 would be more then enough if you arnt going to do eney portwork to the heads or rev over 5500, even the C118 would be enough, there are guys in the 11's with that cam. your biggest power gain is in head work. a 238/248 cam is alot of cam for a mostly stock moter. just my 2 cents
What kind of head work would you recommend Kelly?? I'm thinking of getting my heads ported and maybe my combustion chamber deburred, also am getting new valve springs for the new cam setup. What else would you recommend??
sounds like you are setting your moter good, so you could go with a 238/248 if you port the heads, you will need at least steel rockers with good shafts, headers and at least a 2 1/2 exhaust, at least 3.55 gears with a cam like that.
I'm running Poston's 113A cam. Close to T/A's 413 cam, but not quite as aggressive. You know the car has a cam in it, but it does idle pretty good at 750 or so in gear. Has enough vaccuum to run power brakes, etc. I am using 430 heads that have been ported with Stage 1 valves, but it really gets my car going, even being over 4200 lbs. with me in it. With this cam, and all the a/c equipment, I snuck into the 11's last season, and that was on a warm, 85 degree day and bad traction at Milan during the Buick festival last year. I'll be at Norwalk with a Stage 2 scoop on my hood and looking for 11.70's. I like this cam a lot.
When I got my engine the stock cam was missing so I'm looking for something that will help me destroy all my competition and leave me smiling from ear to ear. The Dyno tests I checked in the Trisheild Performance page showed that the TA 413 was making more torque and hp than the lunati 238/248 so thats why I was planning on running the TA 413 plus I don't know how expensive the lunati cam will cost. Are both of these cams a good choice for NOS?? 70 gsconv what other mods did you do to your enigne to be in the 11's(with slicks??)?? I have a possibility to buy a set of 3 peice aluminum drag lite welds with new MT et skinnies on the front and a new set of MT 26x11 Street Slicks without the rear rims for $1000 Canadian so I guess that would be like 600 bucks US. Think its worth it??
Yes, that was with 26" ET Drags and a 3.73 rear gear. I also run a SP1 intake and holley 950HP carb. Also headers and x-pipe 2.5" exhaust.
With good enough heads you can forget the NOS. The 413 cam with a good ported set of aluminum heads should put you well into the 11's.
Lynxh, I know you've received some responses here but other info would help taylor more accuracy from us. Tranny - auto or manual? If auto, your cam choice needs to match your torque converter - or you'd need a new converter. Gear ratio - don't want a cam that comes into the power band at 3,500 rpm if you are running a 2:73. NOS is like a supercharger so you probably want to steer clear of a split-duration cam.
Yeah I have an automatic transmission, TH 400, I believe that there is 4:12 gears in the rear end I'm not sure though I haven't had a chance to check yet. I guess its the stock torque converter I got cause the engine was never modified.
I'm running a TA 113 cam with a performer intake and 800 cfm Q-jet along with a SP TH400 tranny in a 4000 lb loaded 66 skylark with 3.36 gears and i run 12.11@108 at sea level..1.74 60'..love the idle and i can turn the tires to smoke at a 30 mph just by stabbing the pedal..Bob
Sounds pretty bad ass there Bob. Is the TA 113 cam as radical as the TA 413?? Will it make more or less power than the 413?? Gerald
113 has 228 intake duration and the 413 has 234, so the 413 does make a little more top end, i run the 113a cam like Phillips 70 conv. , it is in between those 2 cams. last year was the first year with my new combo at the track, after fixing all my problems i should get in the 11's this year?? i spent a lot of time going around and around about cams. in my opion a cam with around 228-234 intake duration will run well on the street with a nice lope in the idle, when you start to go to cams that have 238 or more you start to loose alot of low end torque and you have a choppy idle, in turn you would need to go with more stall and gears to take advantage of the top end horse power. with my 3.73 gears and 26'' tire i go threw the traps at about 5200 rpm at 110 mph, so the couple of seconds i am above 5500 in first and second, it dosnt make sence to me to run a cam that dosnt start to make more power untill around 5500 rpms
Poston's lists the 113A cam specs as: Lobe center: 113 Duration: Intake 286 Exhaust 302 Lift Intake .510 Exhaust .491 Power range: 2500-6000 rpm Duration are advertised numbers and not at .050, which is the standard most cam makers agreed to for comparison. If I can find my cam card I'll post those numbers too.
So what cam would you recommend for me the Poston's 113A cam or the TA 413 cam?? What would you prefer I should say if you were building an engine?? Thanks for all your help by the way it is much appreciated. Gerald
T/A's 413 cam specs: Lobe center 113 Lift: intake .516 exhaust .516 Duration: intake 286 exhaust 296 I ran both of them through the Desktop Dyno and the results were scary: T/A 413: 529HP and 536 TQ Poston 113A: 529HP and 535 TQ This was on an engine very similar to mine: 10 to 1 compression, .030 bore, an 850 carb, single plane intake, and heads with Stage 1 valves, and headers, . The 413 has a bit more lift, but Poston's has a bit more duration for better breathing at higher rpm. It's a real toss up. I think you'd be pretty happy with either one. And being as your car is 400 or so pounds lighter than mine, 11's should be no problem.
ta 413 i have a 72 gs stage 1 with the TA413 cam i love it car weighs 3985 w/ me in it i run the sp1 intake w/850dbl pumper old set of poston headers turbo 400 w/3000-3200 stall w/3.42posi w/bfg drag radials275/60/15 the best time to date 12.14 @108.7mph she runs very strong. thats through 3'' x-pipe exhaust no tail pipes. :Brow: good luck with your motor scott
Thanks for all the info guys. Do any of you have the address for the Postons website?? I thinking that I'm going to use the TA 413 cam not 100% sure but I'm leaning that way. Does anyone know what the compression ratio is on a stock 455 stage 1 engine?? Also will I need to change my torque converter if I use either of these cams?? Thanks, Gerald
