Yes, a few small things would push you over 400rwhp.

By the way, pretty nice numbers for an emissions cammed setup. Props to Mr. Elliot and the owner.

I don't know about moving the cats around making it not emmissions legal, the inspection guy told me as long as their there it's in spec, And I wouldn't think that moving them to a diffrent location could change the emission's output as long as they were close enuff to the header to heat up enuff to work correctly..

flywheel hp X .007= minimum acceptable injector size.
So assuming the dyno is accurate, 450 flywheel hp X .007= 32#
There's nothing wrong with going that large. It's just not necessary.

Tune?

Maybe a stupid question, is it a daily driver? If not so much, then try a 1LE a/c delete pulley.

Great numbers with an emissions cam! Im sure with a bit of tweaking youll get to 400!!!
My stock clutch looked fine when I took it out and survived many 4k plus dumps but would slip just enough to keep the rear alive at the track. Im sure if I still had the stock rear and my street twin it would snap like a twig.

good job at the dyno.

Pretty good #'s for a 223/230 112 LSA duration cam.

Not sure how most states are on inspection but most local guys are just worried about the "sniff test" and alot less on the if tghe cats have been moved to a different location.

Probably depends on the state and the person doing the inspection.

I am sure it is a blast to drive.

As long as you are tuned for the injectors you're fine. I have 39# injectors on my cam-only 350. They were a steal and they leave room for more mods.

+1 on what NightTrain66 said, many states only care if you pass the sniffer and have no codes, other than that there's no worries.

I live in CA, not so lenient...

A dyno tune would easily put you over the 400 mark. Still good #'s especially for emisssions cam and mail order tune.

It was a dyno tune. I went a cross the border to get it dyno tuned by vince, Because no one in my area could tune my car. I had a mail order tune from a nother tune but it was way off. he didnt do anything I asked for in the tune, the car ran terrible. Now it runs MUCH better. Vince was a great guy to deal with.

I am really curious to see what the dyno graph for this looks like. Its essentially the same setup I was planning on going with soon.

I hope the injector police dont find out I have 44lb injectors

That's a pretty small cam to be making that much at the wheels. Well done.
