If your gonna go to such an extent to make a high dollar solid roller setup.. Why are you wanting to stick with a ltx manifold.. May as well go single plane at that point..

The best part about the LT4 heads is the valves, and if doing serious head work you will be replacing them with something at least longer, particularly for a aggressive solid roller setup.
The LT4 manifold is internally the same as the small port late LT1 intakes.

Just felt like reading about the lt4 again it reminds me of 10 years ago lol. I'm a bench racer but one who has run 200 mph in the street a few times every summer almost so I'm faster than most. 1/4 mile is quick not fast it's useless imo.
The manifold needs to fit under a c4 hood and be efi for the standalone setup. I debated on going traditional sbc block and using 15 or so degree heads with a custom sheetmetal manifold but I already had so much wrapped in the ltx setup. I know over the past few there have been good alternatives to the lt4 so I was just wondering how much hp if much I'm leaving on the table comparing all out lt4s vs other heads that won't require a new manifold too. If I go different manifold it will be custom, and then that leads to an entirely new setup from the bottom up. That will happen when this motor blows up.

IMO for a max effort NA build AFRs are the way to go...but thats not saying other brands like Brodix or TFS can't reach your goals too.
You never said how much you are willing to spend though? That kind of power NA wont be cheap no matter what, but depending on your budget you can get 650 flywheel from an NA LT1 without going too exotic

I have a brand new bare set of Trick Flow's 21* heads I might come off of. Plus I could hook you up with a matching ported intake it would be epoxied and ported to match the geometry angle of the heads. Travismcgill is running one of those intakes and runs a box stock set of trickflow 21* heads.

These posts kind of make me think as if some one is asking is it possible to build a space ship them selves to fly to the moon. Yeah, with enough money I am sure it is, but if you have to ask, I don't think you have the technical prowess to acomplish your goals.

I think their ported TrickFlows are what you want.
