2007 W120 Cam Too Much

[tjbayless]

Assembling a 2007 for a 1971 Bus. Plan to drive it not a show car. Planning to install a 4.57 ring and pinion to improve highway driving.

78mm Crankshaft
AA 90.5 Pistons and cylinders
Stock VW rods
CR planning on 8.5 though could go higher just want to keep it cool
AS 21 Case full flowed
CB Panchito heads dual springs stock rockers solid shafts
Dual 40 IDFs
Exhaust TBD
I have a Engle 120 Cam. Not sure if this is too much cam for the engine. Looking mostly for torque and drive ability. Just don’t want a cam that comes into the torque curve too late making start and stop driving difficult. Thanks for any help

From personal experience of a similar engine with slightly milder cam (C35) I wouldn't do it again. Bags of power above 3-3,500rpm but like a 1600 below that. With the 6 rib box I had it wasn't on cam below 60mph so cruising was a bit painful as it really wanted to be in 3rd gear! I sold it to a guy who fitted it to a Beetle, it was a great engine for a car. He emailed me later to say just for fun he drove from 0 to 100mph in 4th so it's not like it had really poor low down torque.

It wasn't any more difficult to pull away from stop than a stock 1600, it wasn't all bad and if you used 3500-6000rpm it flew along, lots of fun but in truth I spend 95% of my time driving in traffic to some degree and prefer the low rev max torque of my 2.4L stock cam type-4 despite it having 35 less peak HP

Thank you for the info. That was what I was worried about. Ideally want the torque band to be maybe 1500ish to 5500.

A few years ago I build a 2017 (90.5x78.4) and installed a CB - Eagle 2242 cam.

The customer loves it and has put many thousands of miles on it. He didn't specifically mention and issues so I assume no new is good news.

A W120 is more for a Beetle, Busses need more torque than horse power.

Thanks. I see that CB lists that can in their 2017 kit which will be very close to my build so that may be the cam of choice.

I have a c25 cam in my 2007. Pulls like a tractor from 1500 and up.

Make sure you get the heads straightened out, and then swap to a web 218 or 218/119, and run 8.8:1 with .045" deck height.

A Vspeed ss143 muffler will really tie it all together, and make a great bus engine.

Years ago I built a 2028cc (78.8 x 90.5) for my '68 Bus. Stock rods, AJ Simms 40x35 heads, 40DRLAs, Engle 110 w/1.25 rockers, 1.5" exhaust, 8.4:1. The stroker crank made a big difference for hills, and the rest of the combo was pretty well balanced enough so it made power where I wanted it. I didn't feel like it was lacking bottom end with the W110.

I had wanted to run the W120 just to say it had a W120 in it, but I was advised against it for my application.

so just for discussion, what if someone was dead set on running a 120 in this scenario , what's thoughts on advancing that cam and how well it'd work then?

An interesting thing happens in forums where everyone starts parroting the same thing and "common knowledge" takes over.

2007 in a bus I also recomend the WEB 218. Mine has been together 10-15 years in my 65 Micro, well behaved to drive
