I know, I know that the MS3 makes excellent power with these heads, but from personal experience I didn't like the cam. I personally didn't have it my car but I have a buddy that ran with one and he didn't like the cam putting enough TQ down. I was thinking about going with the LG G5x3? What do you guys think?

i can see the downside to the ms3 on the street. u will definitely suffer in the lower rpm range. u want a cam that will produce usable power on the street where u will be doing most of your driving. if its strictly a track car, ms3 all the way. i just ordered those heads with the tsp 228r cam. it produces higher hp and torque than the 224, and from what ive heard, driveability and street manners are almost identical. im a huge fan of the 224 cams. anyway, just some food for thought

id do the g5x1. great little cam and only slightly bigger than the 228 cam. very usuable.

I've already had the tr224 and it was great in all but I want to upgrade. So I was thinking if going with the g5x3. Would this be a good combo?

id think that big of a cam would be better suited for an aftermarket head. im sure it will work but wouldnt be my first choice.

M6 cars run good with 5.3s and F13-112 cams, oldie but goody.

I talked to LG and I asked them the PTV question and said it would fit without flycutting. I don't think it would be necessary because the MS3 are almost the identical size, right? I'm actually a A4 and go to strip once and a while.

I bought the stage 2.5 5.3 heads and the torquer v3. I think I will be happy with this for my DD.

Also check the link in my signature for details on a "Street Sweeper" camshaft from New Era Performance. The specs are 236/242 duration, .605"/.609" lift, 110 or 112 LSA. I think you would like that cam with your set-up

MVDCGTO

The Streetsweeper cam is actually designed by Flowtech Industries and only sold through New Era, fyi. Its a nice cam but the guy who designed it told me that it requires better heads to support it. I mean anything can be made to run and run reasonably well but I rode in a car with that cam, a set of ET 225 heads and all the fixins. He put down 475rwhp and 430ish torque but it was alot of top end hp, not much down low. Sweet highway setup for sure.

EDIT: I see your putting this on a set of stock 241 heads, good luck. Post your results.

It will be going in next spring/summer and has put down 400+ RWHP on stock heads in the past. I will likely upgrade to a set of ported LS6 heads in the future.

MVDCGTO

Oh I dont doubt that it will put down 400+. Like I said, its going to have nasty top end. . .nasty, but dont be shocked if smaller cammed cars are passing you up in the 1/4. If my car was not such a pig I would have probably bought that cam to go with my PRC heads, its just with 3700lbs I need down low power to get me going. Heavy cars FTL!!! Be glad that f-bodies are reasonably light.

well if your an A4 and u have a stall, u dont have to worry bout down low, cuz the verter and gearing will take care of that!!

just a side note he had to fly cut in fact he got the heads in and put them on went to check the PTV turned the motor over with a breaker bar and acutally bent a valve so......

Sometimes my search doesn't work actually a lot of times, DICK! But it did today. Well what I got was kind of confusing for me. Sinc TSP changed their valves sizes it's willing to accept a lil larger cam. Even though LG is not giving their duration on the G5x3, the lift is similar to the MS3. x3 is lil lighter on the intake side but a hair more on the exh. But that still doesn't matter. For guys that went with MS3 with these heads did you actually check you PTV clearance with the new valve size? I wish I knew the duration on the LG cam so I could make this decision.

When I looked at the internal engine section there were maybe 5 posts in the first 3 pages of threads on this topic. You don't need to use the "reliable" search feature all the time. Simply looking through the first couple of pages of threads usually works for me. You're welcome too

MS3 is the largest cam that won't require flycutting according to Jon at Texas Speed.

The G5X3 will require flycutting. I wouldn't want to buy a camshaft that I didn't have the exact specifications on anyways

That really sucks that they won't give their specs. I'm sure they had to lose some potential customers there. I know I won't go with the MS3 though. But I was thinking of going with the X2. My buddy back home ran with this cam only and hit 400rwhp with just headers and lid. It was on a a4, no pulley, no tb mod. I'm still searching for others. If anyone has others please post your results esp. track results.
