I've always thought VVT is the way to go for a road course/street car (no drag racing). I've been shopping around preliminary for a shop to order a cam kit from and one is telling me they would do a VVT delete in that application. Seems wrong to me but I'm not super experienced in these cams.

Shoot me straight. Thanks

Fyi, we're talking a 2018 SS 1LE with E85 and an MSD intake/95mm TB when I do the cam. Also will probably do heads as well. Nothing crazy with the cam, something small, no crazy lope, etc.

I’m in the same boat, I was thinking about just adding heads and keeping stock cam… but now leaning towards adding a cam as well. See the thread a few posts down about the BTR220. Retains VVT and midrange is as good as stock. I have an A10 and don’t want to mess with the factory shift points/algorithms for road course so my case may be different. I also can’t go with a higher stall converter due to heat so I’m limited to a stage 1 cam.

If you have a M6 and willing to spin it higher recommendations may be different.

I would definitely do a vvt delete and D.O.D. delete kit on a cam swap, especially on an M6. If I'm opening up the engine, all the stock valvetrain stuff is getting junked. At that point a "healthy" non vvt cam (low .590-.600 lift for valetrain longevity, my preference) would be my choice. Never seen someone go to a non vvt cam and choose to go back to vvt, but I have seen people re swap an aftermarket vvt cam and go to non vvt. For an automatic, don't know what to tell you. The more aggressive the cam, the more upgrades ( torque converter, full tcm tune, etc) you will need to make it drivable.

Why? Why give up the low end torque gains from VVT? If you want to spin to 7500 I get it, but 6800 ish not sure I see why you wouldn’t.

even a 220 cam will want more than 6800 rpm, especially underneath a msd manifold. i shift my stock cam at 6800.

vvt & high rpm stability/reliability do not go hand in hand. id trust it to 7k or so in a drag car, but certainly not a road course car. have you ever seen a dod lifter?

i doubt you'll find one vender willing to suggest a vvt camshaft in a track car.

edit: the dyno btr released for the 220 was pulled to 7500.

double edit: you already know this so why would you say anything about only 6800 rpm?

Stop it’s still significantly higher then a stock cam at those levels. I can’t go higher then a stage 1ish with a stock converter. I’d be interested to see what a custom cam shop suggests but for a FBO car it’s hard to beat the research done on it. I’d rather have a cam that has some testing vs a custom that has little experience with VVT. I may block it out idk at this point but I’d like to keep it if it makes sense.

All I’m shooting for is around 550rwhp and A10 compatible (stock TC). I think that would make an awesome road course car. I could go blower and easily hit those goals but the added weight will hurt me. I want to stay n/a if possible.

Not sure about vendor recommendations. Hard to get an answer. I reached out to Pray two weeks ago, GPI last week… going to give BTR a call tomorrow. Hopefully they answer. It’s annoying I’ve got some coin to spend and I can’t get a shop to reply and put together a quote. Oh well

road course stuff id prob contact lingenfelter or lg.

Try contacting Katech. They specialize in road course racing.

Had a G5x2 back in the day in my 2002. Showing my age. (Only 41 lol). And a yank PT4000. I guess that brings up a question….

Does the A10 lock up for most anything over launch? Being road course I haven’t considered a smaller converter, but any thoughts on that?

i'll play - believe it or not i bought the first "g5x4" out of juggernauts car.

and as far as a10 converter / lock up goes, id do whatever i could do have the tuner set the trans up exactly how you want it.

Some great info in here, I really am just up in the air.
