Advice for 1835 build

[Albertoprop17]

Hi everyone, I want to start thinking of the parts that I will need to build my 1835

I already have:

AS21 case with case savers
26mm oil pump with in/out cover for external oil cooler (running on my stockish 1600)
AA thick wall 92's
A pair of 40 dells with 28 venturis
Empi tuck away exhaust running on my 1600 (Sebring style exhaust on the future)

I want to put a 69mm counterweight crank, lightweight 8 dowell flywheel and use the stock rods (properly worked for the build)

I'm considering to use these heads, but I don't know if I need 35x32 or 40x35 valves (I read that if the engine is under 2.0L I can run stock size valves):

Which of these 3 camshafts should fit best in the build?

286º:

282º:

I don't want an engine that develops all it's power and torque in top end, I want something that can cruise well and have a good kick. I'm not going to run it to the redline usually, but sometimes (a few trackdays? maybe)

I also like to do HVX mods to the case for the best head cooling possible

Estimated power/torque?

Let me guys what you think

Cheers from Spain

This cam

Or this
http://vwparts.aircooled.net/Web-Cam-Type-1-Camshaft-Grind-218-1-1-or-1-25-p/00-382.htm
The 218 pulls flatter and not so much top end
Another good option

My first engine build was an 1835 with a VZ-15 cam and dual 42DCNF Webers, 40x35 valves. Low end response was amazing. Personally on any build I would suggest a cam which accepts a 1.45 rocker, like the FK-65 series with stock valves and 8.5:1 compression with 40's, but you might be looking for more power like the FK-7 or 8 with bigger valves. Usually when someone wants to hit the track every know and then it never has enough power.

I have two 1835 engines, one that was first built back in 89. The one from 89 has a pair of old school ported 041 heads, 9:1 compression, and an old crane cam. Back in 95 the chassis dyno said 95hp. I still have it in my 65 bus and it is a torque monster.
The other has an Engle 120 and some average 40x35 unported heads. It runs well, but not nearly as nice as the one with a smaller cam and smaller heads.
If I were you, I would call Steve Tims at Performance Workshop, tell him what your doing with what cam, and go from there. You may very well just need some of his Super Stock heads, with a little more port work and dual springs.
The 40 dells will be great, I have 36's on the bus now, but have run 40's and there's almost no difference.

Well, I think Steve Tims stage 1 heads are a good deal, way cheaper than the heads I've seen in Germany. I don't know how much will be the import duties etc, but I will contact with him when I start building the engine.

For 40x35 heads, the dbilas 286º cam will work very well, right? I want to purchase that cam beause they can build it with the 4 rivet gear and my actual oil pump is for 4 rivet and I want to reuse it.

What cr should I choose? 9:1?

Will the 28 venturis work with that configuration?

Be careful reusing your oil pump.
I reused this one. One too many times apparently

From Orratech, Germany:

Valves 35,5x32 for cylinder 85,5 to approximately 92 mm

Valves 39 (40) x 35.5 for cylinders from 90.5 to 94 mm

Valves 42 (44) x 38 for 94mm cylinders

I will contact to Steve Tims to get his Stage 1 heads, 40x35,5 will suit perfect for my application

Properly ported 35x32 heads are capable of 120 hp and will keep airspeed up for good lower end power on smaller engines, so unless you're looking to make big power in the upper rpm's (which you say you're not) stay with the smaller valves. I have heard good things on here about Tims' super stock (37x32) heads but don't actually know any one running them.

Hope this helps. Al
