RPM LS7 B-3 Cam | Exhaust Clips & Dyno Numbers

Our B-3 cam has been a favorite of Corvette enthusiasts all over the world not only for its amazing power capabilities, but because of its sound and driveability. It truly is the best of both worlds. Enjoy this quick video of some of our customers cars with different exhaust/header setups using our RPM B-3 cam.

finally, somebody who knows to get the idle to redline in a video. Thank you.

[@X3.Rvxlll]

This is why I want a C6Z the sound and power on all motor is just something else😮‍💨

[@vt2704]

Headers,no cat's and stock mufflers in my opinion sounds the best.

[@YELLOW08Z06]

Yep. That's what I've got. I'll never change mufflers.

[@Z3rhairstylers]

Muffler mod or just stock?

[@coreyruttan872]

Badass comparisons! Honestly, I like the white Vette with ARH headers w/ catless x-pipe and the stock mufflers! Is that where you guys do the "muffler mod" on the C6Z?

The sound of a Race Car

[@greggfridline4260]

OMG, nothing sounds better then a camed LS, except a hawt chick telling you don't stop and that may be up for discussion.

[@Lou_sassel315]

I just bought an ls7 shortblock that has this cam already in it. I can’t afford ls7 heads at the moment as the short block was already pretty expensive lol but I have ls3 heads and intake. If I spring the ls3 heads correctly would it be safe to use on the ls7 shortblock? Only thing I can think is the different valve angle maybe an issue but I’d like to ask the experts for their opinion before just assuming 😂

[@Socaloverlander]

Planning on adding a pro charger in future , heads were built by previous owner , what stage do you recommend . These are the mods I have AHP head work, dual valve springs, cromoly pushrods, yella terra 1.9 rockers, AR long tube headers, CORSE exhaust, Haltech 108 intake , MGW short shifter, water pump, belts replaced and dyno at 505whp - those are the spec I don’t know why they didn’t put a cam

Are the Advanced Inductions heads the ls7 260 cc version or 280 cc? Thanks

[@RaceProvenMotorsports]

280

[@GTStuning-]

RaceProvenMotorsports Awesome, thanks. I can't find the cam specs anywhere for a B-3 cam so I'm having a hard time knowing how much milling I can do to the ls7 heads before there is piston to valve interference. Any ballparks for safe milling from previous reworked head B-3 setups? Thanks

[@goworkout100]

@@RaceProvenMotorsports how much do you guys have AI mill the heads? Also what length push rods do you use? I will be using your B-3 cam which I purchased recently.

[@ghtrcp7554]

[@cjdrives5037]

Are you recommending any particular spring for the B-3? I have AHP heads with PSI 1511 springs.

[@RaceProvenMotorsports]

We use BTR but any comparable double spring should work fine.

[@bdun1226]

I noticed no fast intakes..... anything left on the table going to a mamo msd from a non ported fast?

[@RaceProvenMotorsports]

Msd makes way more power than a fast let alone a Mamo msd.

[@justinwachtendonk9587]

Do any one of these C6 Z06’s have high flow cats connected? If so which ones? Or are they all Catless?

Some do yes. Whatever header system we use.

How much hp am I leaving on the table keeping stock exhaust manifolds with cats on my c6z that otherwise has this cam, aftermarket tfs 260 heads, xpipe mamo with nw102 and intake?

50-60rwhp

[@NandoZ06]

How much would these packages make on 91 octane? Thanks!

[@RaceProvenMotorsports]

Maybe 10-15 less ... hard to say... maybe not even that much.

[@YELLOW08Z06]

+RaceProvenMotorsports it's so hard to find info on H/C/I C6z's on 91 octane. Thanks

[@straight_intro]

are those wheel horsepower or crankshaft horsepower?

[@RaceProvenMotorsports]

A dyno measures Wheel hp... not crank. so multiply those by 15% if you want crank

[@IIB1AZEII]

The white Z had no ported MSD and made 7whp less then the black one with ported mamo MSD !? Have you guys tested the non ported MSD/102 NW tb over stock

[@Bsaint]

Karb0n x it was also 96 degrees when the black one dynod

[@RaceProvenMotorsports]

Karb0n x all cars are diff. Some make less than others.. mamo MSD deff makes more than a stock msd

[@IIB1AZEII]

Agreed on both.. However the car that made 7 less whp had a STOCK intake manifold and the other car had a ported mamo MSD - If both had a MSD and one was ported and one wasn't i wouldn't of said anything..

[@RaceProvenMotorsports]

You are comparing the lowest mamo (hot humid day) to the highest stock intake (cool low humidity day). Also look at the last car which made 635whp 558tq you will not get near that without the mamo.

[@IIB1AZEII]

Yeah that makes sense. I know it hard to compare especially when weather is involved - Have you tested a non ported MSD intake over stock ? I I'm going to go with your heads/cam package,Usual bolt ons,but non ported msd

[@RaceProvenMotorsports]

It’s a cam for an LS7...

[@georgemarengo823]

Are those uncorrected? STD? SAE?

[@RaceProvenMotorsports]

Usually SAE but depends... Either SAE or STD.... Uncorrected in the winter would prob make over 650 haha but we never show that unless customer asks.

[@dbarge761]

It's that a safe tune making 620whp!!?? And why do pretty much all of the other speed shops tell me anything above 570ish wheel HP drivability goes out the window?

[@RaceProvenMotorsports]

Yes very safe, the blue car in the video just broke the stock bottom end record on nitrous with this package going 8.95 @ 156mph and drove home from the track. I can't answer for what other shops say we look at our experience and expertise and we have had hundreds of our heads cam packages making over 600whp safely with great daily drivability.

[@dbarge761]

RaceProvenMotorsports is the b3 cam available for purchase outright and if so are the cam specs available so I can have my boardex heads sprung accordingly?

[@RaceProvenMotorsports]

Yes cam can be purchased on our website... Cam card will come in box after purchase. We can sell you springs with it also.

[@trenton.brock28]

Are all of these on pump gas or e85?

[@RaceProvenMotorsports]

We use pump gas 99% or the time on these cars. E85 isn’t too available around us. Also not really a huge benefit on an NA car
