How fast did you go with a popular TA-413 cam in a full weight Skylark?

I have just built a new 462 for the Riv and I'm using the 413 cam this time as per Mike T.

I should have it on the engine dyno next week and will report back with the results. Iron ported Stage1 heads, B4B, MSD trigger. We'll run it with a Pro Systems 950 HP and a QuickFuel 850 HP. On the dyno we'll use MT Super Scavenger headers, but in the car I'll have my shorties.

With the beast weighing in at 4550 pounds with me in it, I ran a best of 12.99 with a basically beat 462 with an oddball TA grind.

I'm expecting 12.7 @ 104 with this build. I'm also guessing right around 500 horsepower and 540 lb ft of torque.

I'll start a "guess the dyno results" thread a couple of days before I head down. I'm thinking next Thursday.

 

Yards are you changing compression i also run 288-94h like to see the difference.Are you going to do any of this with new motor?

 

Thanks for the smile, Steve. Great pic.

This is an entirely new motor. The old one had a milkshake headbolt, so I believe one threaded hole next to the waterjacket has a crack. The shake never got into the pan, but when I pulled the bolt out and saw it was covered in milkshake I decided to use a 1975 core that I have.

The pistons are .010 in the hole.
Reusing my speed pro forged pistons. .030 over.
Using the '75 crank and rods.
Balanced.
Bottom end studs.
Heads studs.
New rod bolts.
Orange Crush gaskets.
TA 413 degreed at 107* (6* advanced)
My Kenne Bell ported and polished iron heads
B4B
MSD with crank trigger.

I don't know the exact CR, but I believe it to be right near 10:1.

I am trying to get on the dyno next Thursday, but I'm having a family crisis and my dyno day might get pushed back a week. I'll keep everyone posted.

 

Great picture!! I think I was there for that. Yur running with our very own Njbuickracer Artie. :3gears:

 

No, I don't think so. I believe that was the final race of the 2005 Muscle Car Eliminator race at Englishtown and that was against Ron Steinhart and his 1970 Olds 442.

As the air temp kept getting cooler throughout the day I'd bump my dialin down a hair. By the last run of the day it was very dry and very cold. I broke out by a very slim margin, but the 442 broke out by a lot, handing me the win.

 

Sweet!!! A win is a win is a win!!

Jeff what are the differences in my TA113a and the 413?

 

It was they had you get to line real quick i went to the tower as soon as i got upstairs you were off i did'nt have time to change setting on camera thats why bad pic.

 

Ok thanks Larry so here's my ?. If I was going to go bigger on a cam, I'd be looking at what? SP 4 or something else like it? Because I have 2 SP 4's in stock.

 

Do you have the specs on the SP 4? I don't remember what it is?

 

Well I guess I'll use the SP 4 on my stroker motor. So what are the next few
tiers of cams for me? I'd like to maybe go bigger. What do you recommend?

 

Joe, you might want to start your own thread for that input.

After reading over the tread, I did not notice anyone using the 413 with TA's Aluminum Heads unless I missing it ? Currently TA is building a 455 for me. I spoke with Mike and we are going with the TA-413. Also TA Aluminum heads with level 1 port work. My transmission is a Turbo 400 with a SP 3000 Stall along with a 3.73 Possie. I guess that for some good numbers at the track I will need some better Tires,{slicks}. Is anyone running ported Alumiinum heads with the cam ? If so I would like to know your track time.

 

I remember reading someone's signature ... here it is

I've PM'd them to come comment on this thread :beers2:

(they're not on the board regularly so it may take a day or 3)

 

Thanks Alan for the pm.

Very happy with the TA 413 cam as well. :TU:

I had talked with JW & Mike T in depth during my build and selected the TA 413 camshaft based on recommendations. It needed Street mannors and vacuum requirements. I followed up with Mike after the dyno session on the fresh build.
Afterward I recall Mike commenting on the power numbers,.. it was the most power he had heard the TA413 make to that date.

Here is a snapshot of my build and story:

The 413 Cam has a lift of .500 but with the 1.65 Ratio yields 0.538"
Choose that cam for street-ability and vacuum requirements.
When we broke-in the 464 on the dyno it was recommended that I use Pennzoil 20W50 Racing Oil & GM oil suppliment... Apparently it has extra additives (zinc) that help during the initial brake in that most newer oils don’t have.
We ran it for 20 minutes at a fluctuating 1800rpm, put the inner valve springs back in, then made some lighter progressive pulls until the rings were being seated in. Having the new engine on the dyno sure was cool, watching the engine make more & more power after every pull and wondering how much power the thing would eventually make.
We then dropped the oil, cut the filter open, all good and put Mobil 1 10w30 in it for the rest of the dyno session.

These fellas had never had a Buick on their dyno, let alone a semi race prepped one. They had been specializing in Racing Hemi Stuff for the past 30 years.

The legendary dyno operator seemed perplexed, scratching his head after a couple pulls on the dyno. I asked him what was up & what the problem was. I had to chuckle when he said “This engine shouldn’t be making this type of power with that little RV cam.” (TA 413)
Actually, the guys at the shop took up a $$ pool, betting on the horsepower that the Buick 464 would make.
The bets placed were between 425 to 525 HP.I had talked with Mike at TA and knew it would be at least 575. I won...

The best part was, mopar shop guys kept coming into the dyno room throughout the day asking what it was making for power, then watching their reaction of amazement when hearing of the increasing numbers. Have it all on vid, strategically placed the camcorder.

The numbers from the dyno were 601HP @ 5500 and 614lbsTQ @ 4500 Not bad for no power adders.

Traction has been a problem. Honestly, on the highway at a 40mph roll, it will haze the tires..
I live in a semi remote area and have tried to get it on the track twice, but both times rained out.
The car hasn't 200 miles on it since the build, tucked away in the shop.

Drag race software estimate 10.33 @ 128mph but just numbers for now..

Here is a copy of the dyno sheet:

 

What heads are you running? Awesome writeup.

We want video!
