Default 600rwhp out of a 415 stroker

I have been talking to several shops about this build.

What do you think would be the most economical way to achieve this in a tunable package for street driving.

Here is what I have been told

6.0 block with the forged stroker 415ci

ls3 heads cnc

cam 302 duration and about 600 lift

10.5 to 1 compression

not sure on the intake or throttle body.

What do you think?

I would say youre going to need more compression and lift than that, and it'd be easier to do it with a sheetmetal intake, but a ported FAST could theoretically pull it off.

600rwhp is a huge number to hit. It's not going to happen with 10.5 to 1 and a .600 lift cam.

Solid roller and you may have a shot.

I've never heard of anyone using a cam with a 302 duration cam.

I am sure he means advertised duration, and not @ .050


That being said, the combo above is not gonna turn the rollers to 600 RWHP. As mentioned above, you are gonna need more compression and more cam and possibly more intake (depending on what yo ugo with)

600 RWHP is gonna take 700-750 FWHP, and that is what I am hoping for out of my combo:

414"
12:1
Solid Roller Duration in the 27x @ .050 range and lift in teh .7xx range. Cam is not picked out yet, but will be in that area.
L92 heads ported
Sheetmetal intake
1050 Dominator
1 7/8 - 2" stepped headers

I am hoping for an easy 700 FWHP, and anything close to 750 would be nice, but not likely.

Street setup? Not gonna happen. You would need a race setup with at least 13 to 1 compression, alot of cam and you might get close. 550rwhp would be a more realistic goal from 415 cubes.

A six speed with a stock rear end and stock driveshaft,(which wont last) with a much bigger solid roller cam, better flowing heads and a excellent sheetmetal intake and you will do it. It's not going to happen with what you are looking at now.

With the compression you are talking and cam, 550 RWHP is a possibility. However, I would think you would fall in line closer to the 500 RWHP range. I mean, to make 500 RWHP, you are looking at making in the neighborhood of 600 FWHP, and 600 is not a number to sneeze at. That is a pretty serious number

I think a 415", 10.5:1, LS3 headed motor with a nice hydra. roller will make 575-625 FWHP.

Look up 408 done by Greg Good and HKE. 11.4:1 Comp, Fast 90, LS6 Intake, 243 heads, and solid roller. Put down just over 600 through an open X-Pipe

It's got a few trick parts in the heads and valvetrain, and a huge amount of knowledge/knowhow in it between Erik at HKE and Greg Good though, but nothing that can't be duplicated with the right amount of money.

Of course, here's an example of what a standard-port TFS cylinder head and hyd. roller is capable of in the hands of the the same people:

If you have a particular goal, your best bet is to talk to a BUILDER who has actually accomplished it before.

I made 554 rwhp on a 402 with 12.5:1 static compression, pump gas, and two mufflers on each side.
I'm after another twenty-five through some tweaking.
Different last name though.

as far as i know i havent seen anyone near that number with a l92 setup. You are going to need trickflow heads, mamofied afr's, or some other extensively ported cathedral port with a ported fast 90. I dont know how much the sheetmetal intake adds, but with the l76 i really dont think it's possible. For ls3 heads i think you would need around 13:1, a cam in the 260 .050 range probably 650 lift, and a sheetmetal intake so it can breathe. Then you would probably still need all the trick stuff like lightweight rr's, ewp, 1 7/8 headers, and probably cutouts.
wckmckd has a nice street setup that makes like 510rwhp, and that seems to be more inline with what people are making so far. Until the fast comes out and people know how much it is going to help, I think you would be better of with tfs heads and a ported fast, there are plenty of those setups in the upper 5xxrwhp range on motor that are built for the street.

Are you sure they weren't mistaken when talking with you and they are giving you engine numbers and not RW numbers?

I would agree that those specs would produce around 625-650hp, depending on how good the head flows.

And, like one other person said here, anything on the street with over 500hp is an animal.
What type of car is this going in? How much traffic do you drive in? Are you concerned with fuel economy? Do you have access to E-85? Does it need to idle below 950 RPM? All these questions really need to be answered before you can really make a decision on what you need.

My 416ci is 513rwhp, people have suggested 20-30 hp more for TF heads might be a possibility, i am also on 1.75" headers as i have no more room. But i'm not about to try and find out as the thing is damn lively as is!

You can check out beckracingengines.com. I believe BRE is almost always a competitor in the Engine Master's competion and finishes near the top. Their line of LS engines use L92 heads.

The numbers on their street 418 are: 668 HORSEPOWER @ 7000 RPM 553 FT # TORQUE @ 5300 RPM ON 91 OCTANE with EFI. This will give you about 580 at the tire. But, this may be a little different configuration than you desire.

Sorry about the confusion. No it was a Fast 90 intake manifold. I was thinking about the heads and intake, and got switched around. Fast 90 intake, Greg Good ported LS6 heads
