Who uses what cam and why?

yeah ive looked i cant find squat in general for cams on there for b350s a few ta212 videos and some comps here and there

 

Seems like most of what you find on youtube is 455's (big surprise) with the 284-88h or bigger.

This one sounds pretty nice, it's the 290-94h in a 350. http://www.youtube.com/watch?v=F5bE8yBeomc

The 284-88h sounds similar. Here it is, but in a 455. 350 would sound slightly rougher, probably comparable to the one above.

212 or smaller just sounds like a skipping stocker. lol

 

Haha, im the one that shot that first video (290-94h). Glad its inspirational! Although i will say that the video doesnt quite do it justice, taulbs lark sounds even better in person!:thumbup:

 

My how things have changed.

 

Im using a custom cam because you recommendet it ahahahaha:laugh::laugh::laugh:

 

Everything has its place. It mostly just boils down to preference and what works.

 

Here's one I came up with some time back. It combines the strengths of the Federal Mogul cam and the ever-popular TA 212-350 with a few other adjustments to come up with a powerband not dissimilar to the Federal Mogul cam when used within a freer flowing environment, with the power and behavioral characteristics of the 212, only with better vacuum, similar lope, and better street manners.

"GF-GS350-109":

Valve timing events @.050 with 216/228 durations and 4* overlap

46
2
2
34

Valve timing events @.006 with 272/284 durations and 60* overlap

74
30
30
62

...when installed @106 ICL (3* advance) from the 109 LSA, putting ECL at 112 for a 106,109,112 setting. This keeps the overlaps even before and after TDC on either side, and events within a performance zone before and after BDC on either side, keeping intake closing early enough for use with lower compression and happy life within an otherwise stock environment.

Lifts are .437/.446 I/E @1.55 for a 2.38 lifter acceleration rate and 56* lobe intensity for both intake and exhaust on symmetric lobes, making wear distribution more even (and gentler) for a performance cam.

This cam is more suitable for use with iron heads with the standard peak flow @.400 lift.

Ideal static compression ratio is 9.5:1.

Simulator results using iron heads, standard valve size, and 205/140 CFM flow (barely over untouched heads) are as follows:

Averaged power between .006 and .050; dual plane high flow with 750 CFM @1.5", small tube open exhaust comes to 372.5 ft. lbs. @2000 RPM, peaking at 398 ft. lbs. @3750 RPM with 349 HP @5000 RPM pulling to 6000 RPM with 329.5 HP. Stock stall or 2000 converter. 3.42-3.08 (3.23 best) rear gearing for frequent street use. Lobe lift: .282/.288. Stage 1 springs required.

Cheap and easy "350 hp 400 ft. lbs." cam with a powerband between 2000-6000 RPM, not requiring much more than stock parts. Freer flowing heads and headers will net best results.

Roller version with greater lobe lifts and use with the upcoming aluminum heads should be interesting.

Trying to decide between the TA 413, and the Voodoo 67003.

3:73 gears
Heads have TA big valve kit, and just cleaned up
TA SP-3 intake
Holley 750 dp
2500 stall
295/50/15r rear tires.
****May go with roller rockers from TA with the 1.6:1 ratio, so lift will change a bit.****

Still haven't ordered pistons yet, so can still adjust cr.

Suggestions?

 

I think Mart ran the voodoo cam. Went flat. he went roller after that. I would go 413 if your got ported heads and higher compression. I'm switching from the ta310 to the crower level 3

 

And that is what scares us the most about flat tappet hydraulic cams...going flat.
But the rollers are so expensive....

The Crower level 4 was also a consideration...

 

I'm sure that would be a good choice also.

 

Look at it this way with a roller;

You'll have the best of the best, and only have to do it once.
You can avoid the fun of removing, tearing down, and having to super clean everything twice!

All the new engines are roller for a good reason!

After the Voodoo, went to 107 lsa, 306/318 duration. I like it. Tachs up quick, torque is softened so I don't blow the tires off.
410 gear with the 3,2k stall keeps it on the pipe.

 

Mart, did you get your roller cam from TA Performance?
nvm....just read your sig.

 

Good, you see that. Don't know why everyone wants so much torque on the street. You would need to run slicks all the time to get bite. I feather my vette out of the hole. Break traction = no go.

 

Kinda defeats the purpose of having all those gears, doesn't it? :laugh:

 

So work on your suspension's ability to plant it to the ground.
Vette's are set up for cornering more than off the line anyways.

 

So said the L88 owner who was running only 11s...

 

Oops, I assumed newer Vette
(Like that wouldn't be a blast?? De-cam it so it makes less wheelspinning torque, lol)

 

TA-288-92H car craft shoot out winner, Shawn Riley used it, Mike Tomaszewski's dad has this cam in his car.
I like that it made 560hp with stage 2 on pump gas

 

You are right abt 11's. My brother had a '69 427/435 tri-pwr. Went 12.20's. M22, 411 gear.
