Is a 416 worth it?

Hard to say really.

You'll want to go bigger with a 416

The cam you have in your sig is barely a tick bigger than my H/C LS3 with 11.2:1 CR. It'd work...but you can do 'better'.

If you go with about 11.5:1 compression, and a cam around 236*/252* and 114* + 4*, you'd have about 16* overlap.

IVC = 49* and EVO = 63*

This is a cam that will hit hard at low RPMs (below 3500 RPMs) and will carry nicely to 6600 with very little drop-off to 7000 RPMs. Would make for a strong road racer and a great daily driver. If torque through the entire curve is what you're after, this cam will do fine.

BOTTOM LINE…..you don't need a huge donkey-dick cam to make a strong stroker, and you don't want a huge donkey-dick cam if this is your daily (or near daily) driver.

Lift would depend on your heads.....so you'd what to have the heads in hand and have them flowed before ordering your cam. HOWEVER....with aftermarket castings, I'd go with about .650" to .660" on the intake and exhaust.

Now....if you want a max power engine with shitty drivability and shitty gas mileage, you can go with more duration and more compression.

Oh yeah.....short runner intakes will pump up your peak HP....but will squash your torque below 5000 RPMs.....so you may want to steer clear of those.

EDIT: BTW......my 429ci in my SS has AFR Mongoose heads milled to 65cc chambers.

416s are very popular for sure. Since 2012 i have built 63 of them and they have been used in anything from Farm trucks with extra tq for work to High revving 8100rpms All Motor setups. Cheap and easy power. Just depending on what setup people want.

With your cam and your mods most likely you would gain 50 ft lb and gain all across the board feeling it in the seat of your pants and make it torquey..... so yes you would love it, but unless you plan to replace the engine anyway its $$$$ say 5 grand for new all forged short block....

SO your torque could come up to your HP rating and yes you would gain some HP and have to get... used to having some new trialing arms and toe links to avoid wheel hop...learn to not get on it too hard or get fishy..... learn to be happy with torque and flashing traction control if you hit gears too hard... It leaves it much more buildable with the option for say some GPI small bore ls7 heads in the future...and I use a MAST stroker windage tray also dremeled/altered more; not just the stock tray with washers.

I am at the wheels on a mustang at 483 torque and 476 hp with a much milder cam than yours and the wide 114 +4 LSA for good torque because I am waiting to build further as I have a couple years to go on major $$$$ daughter graduates in neuroscience in June...… Wife and I had to foot the Credit /bill... SO I take it easy, but with a more ballsy cam like the GPI one in their package; I would expect 550 HP and about that in Torque to the rears and that a lot better than a zl1...…..

Hp may impress to sell a car but Torque wins races..... And I am just at 11;1 run pump gas, get more wilder with tunnel rams ...higher compressions for a more race only engine and you of course get more numbers. I got my shortblock from SAG performance/ custom engine supply from Jerry, consider Thompsons...but hey one had free shipping cheaper price in the winter also the price is often lower if you shop right as shops need work...……. Good Luck

I like your cam rational! Those seem like good specs!

So what you're saying while I'm talking about doing some after market heads. Forget the heads on stock cubes and Save my coin and put that towards a stroker cause heads are 3k plus labor add a new cam and intake and you can see where this is going??

[pavlos1]

i have a 419 stroker from livernois motorsports not cheap but it works.with a dyno steve tune it makes 458 hp to the wheels, and 618 at the flywheel!

No offense but only 458?? With just cam and bolt ons I'm at 470ish. I'm thinking you meant 558, which would be impressive. What kind of torque cause that's what snaps your head back

He's previously posted that his car dyno'ed at "makes 458 hp to the tires and 618 at the flywheel".....which sounds 'wrong'. That'd be a hell of a lot of drivetrain loss from crank to wheels HP.

And yeah....my H/C LS3 is just short of 500hp to the wheels through a 4L60E and a 2 1/2" exhaust.

Now the mystery, is it:


558 rwhp and 618 at the flywheel or........
458 rwhp and 518 at the flywheel

Christianchevelle's motor is a stroker and hes still in the 470 rwhp range, for comparison sake, so ya never know, I suppose. Its all about the supporting mods

[WHAMMO]

You don't need a stroker. To make close to 600hp. Cam only I'm at 595hp. Just slap milled/ported heads and you'll be there with supporting mods.

How much did you mill your heads? What's your compression?
