268/264 cam modifications?

[mikegioia17]

I have a 24v vr6 and want to install 268/264 cams when i install my r32 engine. I was wondering if I would have to make any modifications to get the cams to fit? Shim the valves, replace anything, etc?
I know the 264/260 are a direct swap.

Also what gains amount of gains would i be looking at. I know the 264/260 give you 23hp 16tq but havent seen anything for the 268/264

All the cams I have seen are drop-in other then the regrinds from dBilas which require lifter shims. Ferrea does offer lifter shims for stock base circle cams for stability at high revs (7k++)

Im not planning on reving past 7200 either way

When Schimmel sold them on his site, I saw the gains for 268s put down as - 26hp 18tq

Probably why not many folk stock them any more as the gains are tiny over a 264

Does it at least sound better then the 264s?

Schrick 268/264 are rated by Schricka t 29 HP gain, ALONE. Techtonics was 23 HP. IMO, They sound better, but it also depends on your exhaust setup. The gains however with a Tune, i can only speak to a United Motorsport tune, is really good.

With a Catback, 268's, Tune, Intake, maybe Higher flowing Cats, i can see around 240 wheel HP if not more.

i am planing to dyno.. i have schrick 268/264, um tune. tt downpipes and 2.5 inch exhaust w/no cat. and just a k&n intake... i will try to post up the results as soon as i can.i am curious because i always wonder if i made the right decision to get these cams. or get the more aggressive 272/272 or paying the extra for schrick in general.

I still have my set of custom dBilas FS if anyone is looking to step up.

No difference really.. they all will give the same results within only a few hp. Not enough to feel, not enough to win a drag race. Literally such a slight difference that weather effects results more by far on any given day.

That's what I like to hear I will post up my dyno sheet as soon as I get it

Someone needs these big cams, dont make me build another 24v just to dyno them!

Oh come on Paul you know you want to build another VR6. It's in your blood to drive a Staggered 6 that sounds like beast and drives like a bull with its tail on fire.
