I have a 65 Nova (3000lbs) full roll cage front to back, small tire car, looking for low 10's, and have a LQ4 at my machine shop ready to be put together. Im wanting to be at 550 horsepower to the wheels, no power adders will be added. Pump gas, 10.5 to 1 maybe 11 to 1 compression. Here is what I have: Stock (cleaned, magged) LQ4 block, Gen 4 Rods, Stock crank. Im planing on running a stock LS3 intake and a set of L92 heads. I need a cam suggestion to get me to these numbers. Is this even possible ??? If you respond please give cam specs and not just random un proven suggestions that your neighbors cousins friend did. LOL !!! There are a lot of people interested in what will work and what wont work. Im open to all suggestions so bring them on. Thanks

If your dead set on staying N/A more compression will be needed

Not happening with those heads and intake. It will need to be pretty high strung to achieve 550 wheel with those cubes. High compression, good gas, big cam and some high dollar heads and a high ram intake. Then gear and stall accordingly.

If it's at a machine shop I'd bore it out, stroke it, solid roller cam and a holley high ram, aftermarket ls3 heads. Should run 10s all day.

I just had a 416 built by Tony Mamo

It just put down 691hp on an engine dyno

In my auto fbody it should realistically put down 550-575 to the wheels


Ls3 block
Mamo CNC 240 cathedral head
Mamo ported MSD which helps Carry the power to 7300 rpm which is where you'll need to be on a NA engine 7k-8k rpm
Johnson short travel lifter
Manton 11/32 PR's
12.5 Cr
.036 quench
Race fuel VP Ms109
GZ Vacuum pump
Meziere electric water pump
Mamo specd 247/253 w/.675 lift with 1.8 rockers

So, in the Real World, as opposed to Dream World:

Build your nice low-compression LQ4.

Add about a 150 wet shot. That'll put you RIGHT AT 550 to the wheels. At some low RPM like 6000 - 6500 no less.

For about a tenth of the price of all that other, which while yeah they'll make that number, are gonna have to be REALLY STRESSED TO THE MAX in the process. Yeah they'll hit the number; yeah they don't lie; butt... do ya wanna hit a number, or do ya wanna RACE? How many passes between rebuilds? Therein lies the truth that guides your path.

He doesn't want a power adder though

He wants what he wants, Sure nitrous can get you there. I don't think he talked about budget. To make 550hp to the wheels will need a large cam, if he's dead set on those heads he mentioned he will need a lot of compression 13+ and possibly a big solid roller setup shifting in the 7k-8k to even get close.

RB04Av

Yeah right.

I've got a 305; I read the magazine article where they got 430 HP (or something) out of it; I'm GENIEASS; I want 600 out of mine. Doesn't seem likke too much of a step up. Somebody give me the recipe. Let that thought echo in your head... give me the recipe. Yeah right.

Never mind that the 430 HP (or whatever it was) 305 made ONE PASS on the engine dyno, gave that #, and blew up. We'll just overlook that. Bad luck, used the wrong oil viscosity, ... read the forums and fill in the blank.

OK back to the OP. He's got a LQ4, stock crank, stock rods, pump gas, some nice romantic Lxx names of things he's gonna bolt onto it. Rah rah you GO girl.

Isn't happenin with a cam, like he asks.

Even if it does, HOW MANY TIMES? or, look at it another way, HOW LONG?

Isn't happenin. Either he's gonna have to stiffen up and grow a pair, and do AHELLUVALOT ($$$$$$$$) to his bottom end, FREQUENTLY (and his motor's bottom end too); OR, nitrous. Doesn't too much matter what monkey spank and bishop buffing is in the request; at some point, REALITY has to take over.

550 RWHP (near 700 at the crank, maybe only 650, butt whatevz) ISN'T HAPPENIN with a stock LQ4 and a cam. NOT POSSIBLE. Which of course was part of his question. NO, it is not possible. He MIGHT get 425 if he's real lucky and does a real good job of picking parts and paying really meticulous attention to detail in assembling it. BUTT, there's an alternative way, and we've laid that out for him.

Its looking like I have a pipe dream going on here. Looks like things I have read in articles on line are not the case. All I really want is to go out and run low 10's with my car on somewhat of a budget of an engine. Im not interested in working on the car in between rounds trying to keep it together, looking for something reliable, turn key that's fun to take to the track. I guess I can look into maybe a single turbo set up or that shot of nitrous ??? Lets open up the thread to suggestions on what heads to use since I have not purchased any yet (I do have a set of 317's that came with the engine), and what cam to use. Keep in mind I want to run pump gas.

Turbo

X2 TURBO.
Whats the budget? low 10's in that car will be so easy even with the cheapest turbo buget out there.

Maybe what you heard and read was flywheel numbers? not rear wheel HP.

Bspeck82

Either turbo or stroke it and add nitrous. Should push low 10s to 9s.

I was unclear myself when he stated the original request, as since he said, "to the wheels." Usually when talking chassis dyno numbers, people refer to it as "at" the wheels, or "to" the ground. So you could interpret as "to the wheels" meaning coming from the crankshaft. There is certainly a big difference between the two at that power level. That being said, I'm not sure if even with a perfectly dialled-in setup, you can dip into the low 10s with 550HP at the crank.

Jciowa582

Okay so if I go turbo what would you guys suggest ? Single ? Twin ? what turbo make and model (no cheap Chinese stuff) ? What turbo cam ? What heads would you use (I have 317's) ? Im thinking I will diffidently be over my number by going this route, which is fine.

Ls7colorado

The 317's will be fine, any decent size turbo would get you deep into the 10's fairly easy even with a stock cam.
Once again, Whats the budget?

You dont need a turbo to go 10s. You need to read Tusky Cookbook. Here's a link...

With a auto.... things will be easier.

tblentrprz

Not much detail on the listed combos like:
compression
heads and intake
rpm at peak HP

Curious what you would do to get a 6.0 to 500whp and go low 10s at 3000lbs?

Bspeck82

I'd say put in the biggest pistons you can, holley high ram if it fits, ported msd if space is an issue, 235 heads, solid roller cam, lots of gear tire and converter. Not that hard. Should make over 500 wheel. Need more than average gear and converter for a street car since it wont make much low end torque. Most importantly, a good suspension setup to hook it.

None of those combos were stock crank engines, they were strokers with good heads. A couple of 5.7's were but they were not low 10's
But he still hasn't said what his budget is?

sbf

408 ported ls3 heads or DART LS3 llsr cam vic jr intake carb or 4150 tb 12:1 cr not a budget build but it will damn sure run low 10's
