Help me decide between a 120 or 110 cam

[Lrodri64]

Hi,
I have both cams and that makes the decision more difficult for me.
My engine specs:
76 x 94
5.325 rods
041 heads 40 x 35
hi rev single valve springs, chromoly retainers.
1.25 rockers
4.12 ring and it is going to have 1.58 in 3rd and 1.04 in 4th.
for the moment I have 40idf with 32mm venturies but plans for 48ida copies soon.
Some days it is going to be raced at my local 1/8 mile track but mostly street driven.
Help me decide which cam to use between engle 110 and 120 (I have both)
Thanks and regards.

neither


but since thats all you have, throw in the 120 with STOCK rockers and let er rip!

make sure your deck is tight and compression at appropriate level.

do the heads have any porting work done?

might want to look into dual springs too...?

Yes,
Very basic port on intake

What do you mean with “let it rip” ?

W-120 if you can install dual valve springs.
W-110 if you keep the single valve springs.

Dont bother with either single springs or the 110 if you plan on any kind of racing

If your mostly going to be street with some occasional strip action then I would build the motor using a street cam. A 120 is a tame cam for that size motor and very street able using 44 webers with 36 vents through 40 x 35 valves.
If you could be a passenger in someone's built bug, that will give you a good idea of the performance motor your building. If you want it quick, you need to do some more research or you'll be disappointed.

Slot the lifter bores about 1/4"inward and out ward from each oil gally hole.about .050-.080" wide&deep so the rockers get full time full oil pressure when ever the engine is running not the spirt&squirt vw engineered.I also use the 30 mm pump with those mods.along with the pressure booster spring and oe cooler relief spring.

Hey is TheSamba broken? Where's the post about selling both and buying a Web 163 with 1.3 rockers?

You guys are really falling off. Geez.
