What's up yall...so i just purchased an Lid, and ARH headers 1 7/8 to loosen up some Hp....i plan to purchase a cam and thought maybe an MS3 or MS4 on stock heads....my question is will my heads support either cam and if not what cam would you recommend?
thanks

Cams like the MS series, TRex, Polluter etc etc are grinded with stock heads in mind, they are the biggest you can have with out flycutting the pistons. To me though "Best Cam" is NOT the biggest, but the one that works well with the car and what it is intended for.

In cars that have been stripped down to 3,000 pounds and are geared to the moon, these cams work well and have put up some of the fastest cam only records but in a stock weight form, that below peak hp area of the RPM range, these cams are soft and will be "mushy" but hit 4k and they scream.

It is a trade off.

I would say you need to define what you intending on doing with the car and def getting all the bolt ons like your doing is required. The car will need a steeper rear gear (3.73 auto/4.10 M6) and for the Auto cars, a 4400 rpm stall would be ideal.

I personally went with a Vengence racing VRx4 which is VERY fun to drive on the street and it does pull hard from idle to redline. Does it make the same peak hp as a MSx cam? No but I enjoy it very much.

I hope this helps.

i'd like to shoot for one those cams that pulls hard from idle to redline for now....but i do intend on getting bigger heads like 225 or 215 w/ a S/C....and maybe try some autocross(i think thats what it is) in the future...at the moment i have an A4 and 3.23 stock rear end...
thanks for the heads up Black Scream...i still got to understand how these cams work on one of the stickey i just came across...thanks again

yea too much depends on your complete set up, most ppl cry about how bad big cams are, but me...personally i dont need to pull a trailor. but i do want the thing to pull hard on top and scream at redline. dont get me wrong ive drivin a tr228 and loved how it fealt scooty....but still it still did not fill the need for power. i just wanna know that i can always make a head swap and have more there, now if i were to go back i would get a tad bit smaller like 230 235. but as for driveability it takes alot for me not to like it. i have a buddy with a ms4 vette ls6 heads and stock 3.42s and as fo driveability it seems totally fine??? the "power under the curve" just feels like stock......till it pulls to around 3500 and it feels like a freight train

With an auto you must have a stall to run a decent sized cam. Period. Re-read that again. With an auto you must have a stall to run a decent sized cam.

That being said I think you should closely look at a tr224 or tr228 / 224r or 228r. Couple that with around a 3200-4000 stall and you are talking some serious straight line speed with a very streetable combo. Im currently running a 3200/tr224 combo and it drives fantastic, although not an all out track monster.

The race weight of a vette is a big factor, if he upgraded the gears, it would be much better. His vette, is it a zo6?? If so its even lighter then a standard vetter, better trans ratios, and has better compression which will help with under WOT conditions.

also i just want to b clear....im not in any way bashing small cams and they have been proven also. with a nice set of heads ppl have seen amasing results. i think its all about HOW YOU want your car to feel....i love the big thing

+ i have a very small *****, so my cam and car make me feel like its bigger...lol

and it was a zo6, thats the only reason he kept stock gears, still to this day the fastest ls car ive ever been in.

search for the el torro cam

NAAllTheWay

with full bolt ons and a set of heads you can make 400whp with a 220 cam....so i dk how much power your looking for but i agree with most on here, you do not need a huge cam to make solid power id go with like a tr230....thats just me....everyone is gonna have there own opinion and thats pretty much all it comes down to.

If you get a cam for N/A with stock heads and then try to run 225s and a blower on the same cam, your motor will hate you. Buy a cam for your current setup, not what you hope to run in the future.

NAAllTheWay

^^^^ ah agree and disagree....jimbo you make a good point...but if i were him and say planned to run 225's and SC.....i would get a cam for that setup.....not only will it save about 1,000 bucks between parts and labor if he doesnt do his own work....but a SC cam will still make a hell of a lot more power on a NA motor with stock heads than a stock cam....will def. work for now and be a decent upgrade....and will be cheaper and easier when he goes to do the rest of his work

NAAllTheWay

budget is key if your on a budget...if he makes bank, you are 100% correct, me i would just get that SC cam now and take the 20whp gain(or more)

Yea, if you really want a cam now and don't want to swap it later, then yes, get a blower cam now. The problem with that is, what if you decide on different heads later? Or a turbo instead of a blower? Maybe you'd rather just put a big cam and a shot of juice?

Just saying there's a lot to consider when getting a cam, and I believe a LOT of people rush into it. A blower cam on an N/A car will be a gain, yes, but it won't be as much of a gain as a similar sized cam designed for an N/A motor.

If he's got enough money to do a blower, what's another $400 for a camshaft custom designed for the setup being run? And if the OP is planning on getting heads, cam, and a blower installed, he's probably making some serious money anyways. I'm just saying do it right, and don't make shortcuts. There's no point in putting the time and money into putting a cam into the car that you really won't be happy with.

that's not a bad idea but i haven't looked into blower cams yet....but honestly i don't mind having both cams only because the S/C won't happen till later....however right now i'd settle for the tr224 or vrx4 cams not unless the blower cam makes more bottem end power....as far having buku bucks...that's not me i'm piecing everything together and will more than likely put everything in myself....i got a hobby shop near by so it helps...
