The TA288-98H is just a tick above the 94H, and still idles well. I would recommend that above the 94H...as long as you're changing convertors.
The TA288-94H and TA113 look good, but the 94H wants roller rockers and they both need 3000 or better stall.. Again I think to much for my 308 gears and lower stall The TA288-94H seems to fit the best right know..ray: :3gears:
I had a 113 cam,Its a great cam I ran 12.45 all day long with stock stage1 heads stock bottom end 2500 stall the 118 is the same cam but with 118 center line.
I think he meant the 98H, I was considering this one also but the power brand is too high for me, I don't want to be going past 5k too much. once I finish my engine I don't want to have to do everything all over again! it's been sitting in the garage for too long already! ou:
I have rollers for my 98H, but was advised by someone who knows, that I don't need them. A good set of TA's HD shafts and stamped steel rockers is all you need. But if you plan on changing the geometry of the valve train, then you need some adjustability, or you need custom length pushrods. I elected to go with the rollers for that reason, and also future cam upgrades. I also had TA notch my pistons so I could use a higher lift cam. Actually, with the 1.6 rollers, the lift of the 288-98H is .517. I never go past 5K RPMS running the car. I had the engine up to 5400 RPM on the dyno just to see what the power was doing....and it was still climbingou:
Up to this point I see only TA cams mentioned....I guess Schneider was also mentioned.Does anyone on this board ever use any other brand camshafts? CROWER , LUNATI , REED ,SCOTT BROWN, ULTRADYNE, BULLET etc. all offer very powerfull grinds for Buick engines. Many have quicker opening rate & slower closing rate profiles. Many of these type ( Asymmetrical) camshafts work very with Buick engines & can increase both torque & horsepower in the real world where it counts! I am sure that all the cams listed build good numbers on the dyno, but some my be better than others when it comes to launching your car with a lower stall speed or pulling on the top end with 3:08 vrs. 3:73 gearing or stock manifolds vrs. headers etc. I would love to see a shoot out @ a track, with a half dozen grinds with close lift figures & duration @ .050 & differant profiles with the cars running 3:08's & stamped steel rockers only. On the street TORQUE RULES.... ick
I've run a bunch, a Crower was my first aftermarket cam for my BBB in the '80's. I had a custom grind done by TA (perhaps through Schneider, don't know) in '89 that really favored the exhaust. Loved that one until I killed it with a hi-vol oil pump. Went to TA308S when the engine was going into an altered. Kicked ass. Read about "lifter crash" thanks to others in the know and have kept that in mind ever since. Stuck with the folks who have tried cams and liked them with hard numbers since. Devon
Devon, I have read the dyno test on the TSP site showing 2 cams for street use of about the same lift & duration & LSA , one was a TA(slow ramp) & the other was a Finishline (fast ramp) in this test it shows the edge going to TA's slow ramp, the problem I have with a dyno test like this is were both cams tuned to the highest level i.e. cam timing (adv) ign timing (curve) carb jetting (rich - lean) exhust headers (size) (short long etc.) just because they both shared the same dyno, carb, headers & were installed in the same motor does not mean that one cam is better in the real world than the other. I feel that modern cam development is about max'd out when it comes to flat tappet cams & if the truth be known most good grinds fast or slow with close specs will end up in the same ball park (only after they are tuned to the max.) There are { Asymmetrical} cams that have preformed well with out valve train failure in many engines including Buicks. The bottom line is just that .... there are mechanical & dynamic limits that have to taken in to consideration when designing these profiles. A camshaft that would work well with the listed combo - SB226/240/H13 Scott Brown custom grind or the TA c113 - both are in the .480 .500 lift range & are on 113LSA .050 dur is in the 226-230 in. & .240 ex range . I have found both to be great streat camshafts. ick
I agree, we were just talking about this.. Most of the cams that start to make more power push the power band up and leave us lower geared cars behind.. We are looking at some other brands, or possibly a custom grind :idea2:
With the 2:56 gears I have and many others can probably attest the 288-94h will roast any street tire put under it...it has plenty of bottom end.
dont laugh too hard but i just had a 290-94h 112l/s put in and wondered what a choice this was for 70/ electra / scotty g rebuild/msd/2.56 stock gears/ thinking of breakaway tci/ idles a little rough
Yes, alot of people do like the 288-94h .. I am also considering Scott Browns SB226/240H13 lift .505 in / .484 ex - 226* in / 240*ex @.050 - Lobe sep. angle 113* I haven't heard of many people running that cam.. When will you have it running?
Wanted to thank you all :beers2: and tell you the results of the cam selection. TA 288-94H 71 Motor- 38 over wiesco pistons Heads W/Stage1 valves and ported Stock intake, Heat pass. Blocked 800 Q-jet Shorty Headers and 2 1/2 exhaust 464HP @5200 528TQ @3600 :TU:
Very impressive numbers!!! Congrats Art. Where did you have it dyno'ed and who built the motor. Impressive torque!! Jay
Carl quest Competition in Oakville, nice bunch of guys.. The builder was a friend of a friend "Dino" Who is very good at what he does..
Great machine shop. Only one in thee area that does sonic testing. I wish I had mine dyno'd. What did it run you, 5 or 600? That car is going to haul ass!! Can't wait to see and hear it
$500 + Gas, oil and any parts, I just wanted it up and running so I can install it once!! Knowing the numbers was nice too :laugh: Jay, Take a ride to Monroe, we go to this cruise almost every Friday..:beer http://www.classicnights.com/
Nice Art! Same numbers as my motor (now its apart) with 288-92h. 9.98.1 Compression. Mine are mild port 72' heads. B4B .030 Are you running iron 71' heads?
