Shaun is spot on (as usual).

3/8" is the standard size stud and is fine for your application though 7/16" does have the safety factor. Your not going to run springs that require a strong stud though your right only need to make sure you get the correct sized roller rockets to fit and your sweet.

The Springs required are usually documented as a part of the CAM card - so yes you are correct. You should be able to get the heads with the springs already installed as the CAM and heads your using are a matched pair (which is why I like your choice).

I will have a quick look and see if I can find it for you.


I will someday think of something clever to say.

OK the TSF 1 Cam Specs are below:

Valve Setting Intake: .000 in.
Valve Setting Exhaust: .000 in.
Advertised Duration (Degrees): 275 intake/279 exhaust
Duration at .050 in. Lift (Degrees): 221 intake/225 exhaust
Camshaft Lift: .312 in. intake/.319 in. exhaust
Valve Lift with 1.6 Rocker Arms: .499 in. intake/.510 in. exhaust
Lobe Separation (Degrees): 112
Intake Cam Timing at .050 in. Valve Lift:
Opens 3 degrees BTDC
Closes 38 degrees ABDC
Max lift: 108 degrees ATDC
Exhaust Cam Timing at .050 in. Valve Lift:
Opens 49 degrees BBDC
Closes 4 degrees BTDC
Max lift: 116 degrees BTDC
Firing Order: 1-3-7-2-6-5-4-8
Characteristics: Good idle, strong mid-range power. Aftermarket intake, heads, and headers recommended. Requires modified Mass Airflow sensor. Best with 9:1-10.5:1 compression ratio.
Valve Springs with 1.6 Rocker Arms: TFS-51400413
Valve Springs with 1.7 Rocker Arms: TFS-31400414


So the TFS-51400413 are the stock springs they use on many of their after market heads. See:

www.trickflow.com/part...toview=sku

You should be right as the heads look like they might be right. I only like to see the seat pressure to make sure.

www.trickflow.com/part...toview=sku

OK found a data sheet for the heads on this page

www.trickflow.com/part...S-51400004

It is on the second page and the springs would be fine for the TSF 1 CAM.

Notice they spec a different spring with 1.7 rockers, the 413 spring must bind.

I'm running 1.7 rockers on my engine. But this will compensate some what for the flat tappet cam I'll be using from my parts bin that has emassed over the years. I don't like to buy stuff if I have some thing in the cupboard that will do the job. I've had this cam lieing around for years still in the box. I had the 1.7 rockers in the cupboard as well.

Cheers boofhead. Do you do this for a living or you live a second life afterhours building engines/cars?

I will go the single springs with preferably 3/8" studs and 1.6 rockers depending on what stock summit has in at moment. Otherwise might have to go 7/16" and the more expensive rockers.

Hip pocket is going to cop a hit this month. haha.

Trav.

Are they a single with a damper or just single? Always like to have a damper, doesn't add much, but limts hamonics in the spring. But if they make the cam and the spring it should be a safe bet in any case.

Shaun - They have a damper.
Trav - A second life. For me this is a hobby and keeps me out of trouble.

I feel that if you can help each other out then we can all enjoy this hobby with the side benefit of meeting more people while keeping these cars on the road. Engines are my favourite aspect while body work is my least preferred aspect. At the end of the day I do enjoy it all.

Keep us informed with how you are going with it all.

Nassi,
Why is that you got a suggestion or copying the list?

I have a us postal address service so get pretty cheap postage rates if you need something shipped by the way.

Boof - I am the other way hand me a spray gun any day over engine building. I pretty much taught myself that so this is my next challenge. Going to pick up a nice warren and brown torque wrench Monday as I don't trust my current one should have all my bottom end bits by next weekend.

Cheers
Trav

Sounds like we would make a good team. Your engine will be a good one I am sure. Enjoy building it. If you were local I would not be able to help myself from coming around and poking my nose in how it was going.

Yes Trav, possibly copy it if my other option falls through.
The TFS gear is the same as Boofhead recommended for mine I'm pretty sure.
cheers

Nassi you can always send it over with a box of Dark & stormy's and Boof & i will build it for you in my shed. Just don't send it on Friday in case we go to the titty show & raffles at the Queens port.

The questions have been very good so the thread quality level is great for future reference. That is why a conclusion would be great as well - e.g. I am very happy - the motor build went well and she is putting out 300+ HP.

Scott - LOL. The solution to a good build is the 3pm Friday Topless Jelly wrestling, e.g, no work gets done at all while under the influence. (or should I say 'too much influence').
