All my stock heads have that lip, at least the LS3 ones, I haven't checked any cathedral port ones.

I was planning on trying the Super Vic and 4500 on my 6.0 in the car for the heck of it before I swapped motors, but I'm not grinding on those heads as I have a potential buyer for that engine

my cathedrals don't.

To me, a small amount of grinding is a whole lot less effort and pain in the butt compared to having to drop a load of cash on another intake from a different company. Not to mention CHEAPER.. You still have a nice intake and the area where you ground on with the dremel is not a critical area like a cooling passage wall, so basically no harm done and you still get your performance gain from the intake.

Good luck with the possible sale of your engine.

My L92s have that lip at the top of the port too. Not sure why, it looks useless.

That's the extra casting material before the area machined for the intake was done and they only removed what was needed to use a EFI intake.

Well guys after all the BS of waiting for the intake and finally got my engine up and running, It looks like I'm gonna have to get rid of the Super Vic. Just found out one of the rule changes for my class is have to add 75# to my car if I run a dominator. This SUCKS!!!

I'm sure the intake and carb won't make enough power to make up for 75#

Run a BIG 4150 on that new super vic

Sorry to hear that man. What about running one of the adapters to go from 4150 to 4500? You can keep the intake and still be in compliance, plus get the airflow benefits of the larger runners.

I'd still see what it does....and then decide IF the 75# (in the right place ) will be a factor ?
You already have the parts....right ?

This may work too ?

back of the car, tractor weight bolted to rear bumper support..

or to roll cage using U-bolts over rear axle?

You can get a 4150 with a dominator bolt pattern. Not optimal, but it works.

my ultra 950 hp has both patterns

I've mentioned to Benji to at least test the larger manifold with the larger carb.

I believe he will be trying it when he gets his carb back.

I don't know if this applies in your situation, but I read a couple guys say on The Bullet that their Mast Dominator intake did not show any power increase over a Victor unless it was used with a Dominator carb.

I do plan on trying the Super Vic with the Dominator, the Dominator just has some issues the builder has to fix before I can.

A carb with the dual bolt pattern does have my attention as like an idiot I just had my car painted over the winter, IF I run a 4150 to 4500 adapter, I need a new hood as I won't have clearance.

Most of the builders I've spoken with have told me that I'm "pissing in the wind" trying to get the car dialed in N/A since the build is around a N2O cam/converter

They all agree that my engine needs a Dominator if it were a N/A engine and that I'd be leaving power on the table with a 4150.

However, they all said the car will go faster on the spray with a 4150

We will see I guess.

I don't agree with not tuning the car n/a first before you spray it. You have to get your carb tuning and timing baseline right before you start adding the nitrous.

I tuned my last motor till I got it to go down the track at 13.2:1 AFR then I started the nitrous tuning. What the carburetor guy said is I'm not going to get this engine at 13.2 to 1 with the carburetor I have, he said it would definitely need a Dominator to run naturally aspirated. But needs a smaller carb for the nitrous.

Curious who the carb guy is? I've gotten some pretty fast **** to run with a 4150.

ZONES89RS

For real, I have not seen any back to back that showed a MADD improvement over a 4150 unless it was a big motor.

Let me rephrase so I don't confuse myself mainly lol.

I was told my engine was borderline for a dominator. Some shops say I need one, most say I don't.

I don't want a dominator on the car because now my class is putting 75# on 4500 equipped cars. So, 4150 it is.

As far as the tuning, the current carb on the car is my Pro Systems 950 that was done for the 6.0 (It's all I had) It's just too damn small for the motor and can't get the AFR where we want it because of that. I ordered a `1000cfm 4150 today, so we will see how that goes when it arrives.

In the mean time, I now have to sell the Super Vic and the Dominator. Using an adapter is out of the ? since I have hood clearance issues
