Fever,
The duration split is to much on the camshaft. You are blowing torque out the engine. Also with the lift on the exhaust you are multiplying the effect. A cam change would be a good gain.

The cam # is 50299LUN
The grind # is RRB1-232-242-A

To change the cam the motor has to come out. I was hoping to pick up some power with a better intake,flame arrestor,carb jetting.........
I was planning to pull the motor next year for a few mods to the heads. I will probably change the cam at that time.

Okay. They use the same grind # but yours is ground with a 114LSA and a 112 intake centerline vs the one I pulled up with a 112LSA with a 110 intake centerline.

Here is a pic of the HV2000.

Notice - the curved runners, the lengthened intake dividers that help with torque and lessens some of the 'runner to runner robbing' , 4 corner water circulation, higher carb mounting height, to name just a few.

Basically, all the 'tricks' have been used on these intakes. Take a long hard look at both.

With the info given what kind of gain do you think I will see with the intake,flame arrestor,jetting change?

think outside the box,
Get a merlin or dart short block and use your heads and intake and carb on the newer short block.
No replacement for displacement.
seems like you have spent some coin on this thing and you dont have to pull the motor to yank a cam, you can drill through the fiberglass part "firewall" so to speak under the back seat so you have enough room to yank the water pump and timing cover, then yank the lifters, then pull the cam foreward through the hole and out
Now some people dont want to drill and I can understand that but you can always fiberglass that hole back up with the piece you cut out, use some marine tex and some fiberglass and resin, hr worth of work and hole is patched up, let sit for 24 hrs, then sand smooth and boom you cant tell
Just a suggestion is all.

Get yourself a bigger block (merlin makes a 600 cid)
dart makes even bigger I believe.
upwards to 700 cubes.
You ahve enough in the heads with a better intake to make more power.

merlin blocks are around 1700 bones,
rolling lower assembly probably set you back another 1500 ish give or take.
but it all depends how wild you really want to go.
I like blowers but I also like the challenge of building a NA motor to kick a SC in the rump too.
i built twin torque monsters for mine but Now I shot myself in the foot, cant get props on there that dont blow out.

Becareful what you wish for
you just might get it.......

Good luck man
