Hi guys,

I am after some advice on what cam to choose for my new 1776cc type 3 engine.

At the moment it's stock but I'm after something to give a little more poke and a slightly higher power band.

Details of engine:

1776cc (90.5 x 69mm stroke)
stock crankshaft
stock type 3 heads with scat heavy duty single springs
stock german lifters (just been radiused)
stock pushrods
megasquirt fuel injection with single throttle body
everything that can be has been balanced
street application primarily

I have been recommended and engle 100.

The main consideration I have is that I want to turbocharge this engine in the not too distant future and don't really want to have to change the cam again later if it can be avoided. Thinking a small turbo, nothing too radical.

Also, what benefit would be had by using straight cut gears apart from a nice noise and no cam thrust? Is it worth doing?

I welcome any recommendations!!

Cheers, Toby :tu

go up a bit bigger to a 110 or a 120

forget the straight cuts gears unless you want a headache when your driving the car all the time

I read it on FACEBOOK so it must be true

Cheers Dave!
What is the difference between a 110 and a 120?
Also, as the lifter faces are newly machined can I use them for a new cam?
Any more ideas ppl?
Thanks... T

PS Heads have had the semi hemi treatment too and for now I am running std deck height.

If you are planning for turbo in the future you can go for an Engle TCS10 grind that is like engle 110 inlet and 100 exhaust.
The wider lobe centres will make the car smoother idle
and also extend the top end more than the same cam with their standard lobe centre.
Also it will open the exhaust a little earlier to help spool up tme.

yes as long as you run the cam in on initial start up they bed together

If there origional VW lifters then they will be good

I like the look of the tcs-10 cam.
Anyone know where I can get one in a hurry?

I forgot to mention that the type 3 rockers have a ratio of 1.25 to 1.
Is that going to cause a problem??

Lastly, does a new cam come with bolts for the gear so I just drill out the rivets on the old one?

Thanks for the great advice.

vw54 - the lifters are original VW. Better than some aftermarket ones from what I've heard.

Cheers, T :tu

some cams come with the gear n some dont Vintage can fit the gear for you if needed

Have a talk with Vintage 9789-1777 they may have the cam u need

OK so with the 1.25 rockers n new cam you will have to check the rocker geometry and may need to fit longer pushrods made to corrrect size only can be done when engine is assembled

Thanks vw54,

Yeah I've spoken to Michael a couple of times already. Boris is on holidays.
They could order one but if I can I will just order from the US myself this time.
CB don't list Engle cams, nor do Cip1.
Any suppliers I should try? International mail order is fine too.

Daimo, straight cuts are very tempting actually. Have you used them? What to they sound like?

Cheers, T 👍

yes, everyday!!

i'm actually annoyed they DON"T give me a headache😎

i think in a type three you would have no problems with them being noisy.

someone had a turbo grind cam for sale a while back, may have been "humpty"?? it was a engle TCS 20 tho.

found that too🤓.......

try Rod Penrose for new cams too.

yes like Dave said, watch for rocker geometry. "shoptalkforums" has some good pictured threads as a sticky at the top of the "engine rebuild" section

when do you stop tho hey??? new cam, pushrods, springs, solid rocker shafts, swivel feet..........exhaust, mild port, BIG port😂

i never did find that point to stop at with my build🤪

Thanks for all that!
I found the post as well and have messaged him.
His is a tcs-20 which would probably be great once the engine is turbo'd.
I am not sure how it would go n/a which it will be for possibly a while.
Since the engine is injected it should be possible to "tune out" any rough spots that may exist I suppose.

Man, I followed your last Berg engine build...that was frigging awesome. It must have been a real trip putting it all together! I also remember the part where you went over the valve geometry etc...

I forgot to mention that I have Berg swivel feet on there now so will I still have to change the pushrods?
Also just bought some new scat single "hi-rev" springs which I plan to use.

Cheers, T 👍

Rodney should have one in stock,
and a bolt-on aluminium gear unless you want to spot-face your stock gear after drilling out the rivets.

02 42 729 920

Apparently you CAN use 1.25 ratio on them, but that is not the stock rocker ratio for type 3s.

you will just have to sort geometry once you have the deck height calculated/finalised and done a dry build. it is something that will be individual to YOUR motor

shimms change the contact point on the valve tip........

pushrod length affects the adjuster screws "squareness" (at half lift) to the pushrod/valve........

much easier to understand once it's in front of you👍

oh, i've got a turbo cam i have prolly out grown if need be

I understand but I reckon I will have to leave that to an engine builder. Not having the know-how and tools makes that decision pretty easy for me. I'll do as much as I can and then get it sorted out if need be.
What have you got?

I'll just grab a newie anyhow...

I will call him tomorrow as well.
I must be wrong about the ratio. They are stock type 3 from a 6v case built 1967.
I thought they were 1.25. What should it be?
I think I will change to straight cuts.

Rockers will be 1.1 : 1. Personally I prefer new lifters AND cam to properly break-in together, and retain base geometry.

Hi all,

Well I decided to go back to the non turbo grind after all.
I won't be fitting the turbo initially which could even stretch out to 12 months as these things often do!
So...I have chosen an Eagle cam very similar in grind to the Engle w-110.
Adv. Duration 274° / Dur. @ .050" 234° / Lift @ cam .387" / Lift w/1.1:1 Rocker Arms .425"
I hope this will be a good match for my engine and estimated HP!
Also ordered straight cuts - steel on steel from CB.

Can't wait for that and all the other goodies to arrive so I can start building!!

Cheers, T 👍
