2007 Head Cam combinations

[66brm]

Hi Guys, picked up a cheap 1835 that I am going to rebuild into a 2007cc, just looking for suggestions on cam, CR and heads for a DD

Ancillaries are 40IDF's 30 vents, A1 sidewinder, in a 1964 T1, stock trans, 010......

I was thinking something like a WebCam 163 (seems between an Engle W110 and 120) with ACN L3's, at 8.5 CR. Thinking I'll probably need dual springs with this combo.

Or should I think about larger valves up to 40 x 35.5's?

Sounds like it would rip, whats the low rpm drivability like?

Yeah, with a 2 liter you can effectively use bigger valves. DRD/AC.Net L5 heads or Tims Stage 1, can't go wrong with either of those. Never used a Web 163 but if you are looking at something a little different you might consider Steve Long's SLR cams. These are the old Erson grinds. Something like the XR296, 296/254 duration, 0.366/0.512 lift w/1.4 rockers. DRD sells SLR cams and he says this cam is great for a street motor, lots of pull to 6k. Probably work really well with the 40IDF's. You can also get a set of reground parkerized lifters to go with the SLR cam.

the one darth sugested has low lobe lift,(witch I like ) witch should be a good one and last a long time just use the 1.4 rockers like he said and it should be the butterflyes eyes.(I would use a 1.55 or 1.6 ratio,but the 1.4 would be nice)

[66brm]

Yeah I think its a line ball on the L5's, reading Johns (ACNet) description it may be over kill on the porting side but the valve size would suit.

I'll have a gander at Tims heads( Their website seems to be gone)

I run 40 intakes on my current 1600cc but want this combo to be better matched

This website is no longer available. That's not good. Here's their ad in the Samba classifieds: http://www.thesamba.com/vw/classifieds/detail.php?id=1069091

On the L5's, you can never have too much port work. 40 x 35.5's match up very well with 90.5mm P/C's. 42 x 37.5's....that's over kill right there.

Darth, would the 256 deg (Web Cam 163)/(SLR XR296) 230 deg durations make a huge difference?
Will be running 1.25 rockers, is it worth considering running different lobe centres? or advance/retard the cam as the engine will see most of its time between 2500-4500rpm with occasional squirts to 5000+

The Web 163 has 249 duration while the XR296 is 254. Not a huge difference in performance but you wouldn't notice the drop off in power as much above 4500 with the XR. However, the XR296 is designed for 1.4 rockers. With 1.25's your lift would be about 0.457" compared to the 163's 0.479". As far as running different lobe centers or advancing or retarding the cam....Time to call in the experts. All I can suggest is contact the guys at Web cam or Steve Long Racing for their advice.

I have ran many cams in my 1955/2007cc combos

by far the web 163 and web 110 are my favorites, quiet and the 240 LB open valve springs seem to cope just fine
if the carbs and exhaust is tuned right you can pull smooth from very low rpms even with that web 110 (I was just marveling at that today on the way back from work , we don't need no mild cams )

port velocity makes more difference than anything, ported 043 castings like the panchitos are the way to go, or something similar

[66brm]

Yeah I was also looking at Brothers oval ports potentially, keeping the port size reasonable so port velocity is good, then throttle response doesn't lag behind.

modok, the 240 lb springs you mention are they a HD single or dual?

I think overall any of the heads that have been mentioned will work well, just need to find the right ones

The heads I am running now are mostly copies of how berg used to do them, the intake ports do not look big, that's for sure

My springs are fancy oval wire beehive singles, but you can get the same pressure out of strong HD singles shimmed close to bind or perhaps cb dual springs setup easy

so I take it you didn't buy that big old low compression sucker you were looking into?

[Cptn. Calzone]

I recently stepped up to the web 163 after speaking with q uite a few folks who run them in a 2 ltr bus. Heads are Timms 1 1/2 Dell 40s sidewinder header. Looking foward to the torque and pull for my work truck SC.

Did a thorough clean up on the case yesterday, 1st line bore, the bearings on the crank still have the ink stamps visible, I think I have a name for the heads.......anti Bergs, weld up the chambers for heaps of squish (even on the plug side), insert larger valves, flycut till you remove the first cooling fin, get down to 40-45cc chambers then slap 2mm spacers under the barrels to get the CR down, and run a 911 fan with dual KDuds

THat's crazy!

[66brm]

Oh and I forgot to mention they put the step back in, but only 1mm or less
