It had to happen.
Martin Smallwood speced my cam. Iirc he and Kip co-designed the LLSR and Martin has his own proprietary lobes. IMO. He nailed it.




you may get close your wish, I know a member here considering
MMS 235s for his 416" build for his trailered drag car, don't want
to give up to much of his combo, its in the planning but pretty
sure it will have a LLSR.
On another note Pretty sure we will see a 416" with MAMOFIED LS3s and comparison between long & mid-length runners on a FAST also.

Member really needs to go with 250cc MMS intake runner espically since a solid roller go be in place...
Solid Roller & High revving= milk n cookies
A 416ci motor has enough bore to make magic happens in my opinion. Encourage him to go 250cc!!
Ive seen Richard Holdnerer take a 408ci motor with AFR 245s out the box and make 630 hp with small headers and pump gas compression (11.0:1).
Also remember the discussion we had about 20 LS intakes tested article in Hot Rod Magazine.... Richard made 592 horses with a Fast intake with AFR 230s out the box on top of a forged 6.0 motor. It did well!!

In this instance I concur with Head designer.

Why put a 235cc head on with a SOLID ROLLER setup thats go turn 8500 rpm or so? It doesnt makes sense at all.
Now a 250cc head will give the motor room to grow down the road. 235cc runner go be DONE at 7400 rpm max while the 250cc still go be breathing in my opinion. Must I remind you I spoke with a guy thats respected just as much as Tony in the LS community and ge says otherwise. Also he dyno/tune cars and spec cams for a living all day everyday so he sees all kind of powerbands on different builds.

Whoa,
Take a long slow deep breath, pause, count to 10 as you slowly Exhale,
Repeat.
Couple points to consider.
1. This is his build, not mine or yours.
2. He has assembled and built several LS Engines successfully,
I have not assembled an engine and I do not believe you
Have either.
3. He has no desire to spin 8500 RPM or even 8000 necessarily,
I believe he would like peak HP~7000RPM & shift @ ~7500 RPM.
4. A 2.10" intake valve is ideal for a ~4.070" Bore IMO.
If I was going to a 2.165" Intake Valve I would go to the
AFR LS3 260 rather then a 250 CC Cathedral but that's
Just me.

Now if you're gonna say Ed Curtis or Brian Tooley I hear you and they are well respected. I've held off on this post because I don't want to come across like I'm trashing an engine builder - which I'm not.
But I think Tony knows his own heads and their capabilities quite well.

1. It costs more money to go soild roller.
2. You mentioned the car go spend more time on the track than the street.
3. If 2.10 was better suited for 4.070 bore... why would GM put a 2.16 on smaller bore motors from the factory.
4. The AFR LS3 heads are not PROVEN performers yet.
5. It dont makes sense to me neither putting a square port head on a 388ci with a hydraulic roller neither.
DarthV8- the guy i spoke to is actually a guy that know how to spec cams to any head!! Period. Ive seen him make a afr 205 head (402ci) trap 130 in a 6 speed car that was nearly 3800lbs with the driver. When i say hes respected.... its a understatement.
Must i also mention he have helped guys get over 500rwhp on stock bottom end ls1 cars.... f bodies at that..

What I was responding to was "Tony must have been drinking...". I'd advise calling Tony up to understand why he said it first.
Why dont yall guys take notes? 520 rwhp on a stock bottom end with a fast 102mm intake and hydralic roller threw a AUTOMATIC 4L60E with track numbers to prove that it hauls ***!!
Again... this S#it is not rocket science to pimp with Tusk.

I forgot about that one completely. I noticed Tony like Comp Cams sticks. I'd love to see him build a street stroked LS3 with his 235s/FAST/LLSR. That would be a blast on the street.
