So after long wait and lots of research I finally pulled the trigger on a mamo top end set up.
My goal is to get it as close to 500 as possible
My current set up is
2002 ss
Ls1 -3.2 dish pistons, forged rods and stock crank
Tick sns 3 (235/243 111lsa) , stock 243s with btr 660s and trunnion upgrade , ls6 intake stock tb slp lid, 42lbs injectors, aeromotive 340lph with Hotwire kit, ls7 lifters, 1 7/8 long tubes off road y. All through a monster stage 3 and a mwc nine with 3.90s.
Was really hoping to at least break 400rwhp and only dynoed 379, could be a multiple of scenarios but just said screw it let's get this new build going
Picked the mms 220s mamofied
10mm upgrade with the yt rockers
Johnson lifters
Msd intake mamofied
Custom cam on the bigger side of things
And going true duals on the car as well
Let's see how this goes, work in progress but hopefully it's worth it

Breaking 500+ with a stock bottom end ls1 and pump gas is very doable, but requires crossing your T's and dotting your I's

500 is a real stretch but it is possible. Keep us posted

I see you're working with Tony to get it done, which is a great move. And I'm sure there's more to your build list than what you posted up. Here's a few items I'm throwing out just to make sure they're on your list.

ATI dampener
Electric water pump
Light clutch

Also, consider the following options to get everything you can get out of it:

LLSR instead of hydraulic roller cam
Electric or manual steering
Crank scraper

Don't be afraid to spin it. Rpm is HP. You'll likely max out torque around 430-440. It's justball you're gonna get from a sbe 5.7. The higher in rpm she peaks, higher the HP number will go.

Good luck!! Enjoy the build and working with Tony

You could get more tq sbe if you cranked up the compression and used e85

Not to gum up the thread, but what would be the advantage of a LLSR over a hydraulic roller?

Several:

* better valve control which will support more aggressive ramp rates and higher rpm.
* no pumping up and down delays
* higher oil pressure to the rest of the engine (I saw 13 psi gain at hot idle from 25-38)

The ONLY advantage to a hydraulic roller over solids is maintaining zero lash. After that, generating tq, revving, controlling valves, solids are better

I'm ordering the ati as well, the clutch is getting swapped as well eventually.
Yea ots gonna spin alright shooting for 7400
As of now I haven't spoken about a llsr setup but there's plenty of time to go ahead and get that going as well

All good suggestions so far, while not necessary I will throw in
2 for consideration, Carbon Fiber Driveshaft reduces weight &
NVH, acts like a dampener on the back of the Crank, really
Smoothes the high RPM spin, and R.E.M. Polishing the Ring &
Pinion, should be worth 6-8 RWHP, even more with a 9". I
hope to be Dyno Testing the delta by the end of August.
Also agree on the LLSR, worth 15+ RWHP even with equivalent
Specs adjusting for Lash, along with ability to go .030-.040 more
Lift everything else equal. Something like
237/243 .680"/.660" LLSR VS 231/237 .630/.610" HR
Spitballing here not giving a recommendation.
Working with Tony is a great decision as both
Darth & I can/will attest.
Good Luck!

Interesting....your initial build my current set up are pretty similar. I also have SBE and SNS Stage 3. Same fueling, same clutch. I went TFS 220 as cast heads instead of 243s, Morel drop-ins instead of LS7, 92/92 set up instead of LS6, Fast Toys 106mm Lid instead of SLP, and through a S60 w/ 4.10 instead of the 9in w/3.90s. Put down 430/400 on Pat Gs Mustang Dyno. I know that dyno vs dyno differences and all that but a little surprised we got such different results. I have a few little things besides what is listed but nothing too drastic. Can't wait to see what your new build results in. It should be a nice jump.

Yea I have no idea why the numbers seem so low on my car like I said could be a number of things but the car pulls strong, didn't get a chance to take it to the track to see what the car can really do

Yes I been looking at the carbon driveshaft it's gonna be a work in progress that's for sure

Did James Short happen to be the tuner you went with?

“Was really hoping to at least break 400rwhp and only dynoed 379”

Seems low… i’m new here but i have a 1985 camaro with an LS1 swap from a 2001 camaro, replaced the fuel pump (upgraded, forgot the specs but it’s from summit, good for 500whp)
and a full hooker race exhaust, T56 transmission, and it got dyno’d at 340.2 whp @5200 rpm and 362.1 ft lbs torque at the wheel. looking to do a cam that won’t cause me much loss of low end torque. don’t know what cam to buy, or lifters/ rods/ anything else i might need.

I would highly recommend short travel lifters. They give you ease of a hydronic lifter but act more like a solid lifter.
