340 stroker

AJ, back down 1 cam size, 224@050 and port the heads. Find a high lift cam and use 1.6 rockers. A 108 is what your looking for on the cam. The engine is large enough for it. You should have a new peak around 6K.

I'm already ahead of you, and
already been there, except for the porting. The 223* was my favorite, and I spun that one to 7000 as well. Current cam is .549/.571 IIRC with 1.6s
I did not like the 292/108 Mopar cam tho
I'm not looking for more power. I got way more than my chassis can handle. And I'll be 65 here in a few weeks so it's time to slow down IMO. And I'd like to get back to those earlier mpg numbers that the 223 was giving me, so I can afford to drive it a few more years.
I'm gonna trade away a couple of intake degrees and a few exhaust. Then I'm gonna wind up the overlap, split it, and share what's leftover between compression and power. Then I'm gonna target 190psi, and increase extraction. Then I'm gonna tune the dickens out of it, and install my hiway gears. Then I'm gonna chase down 30MPGs US again, point to point, cuz 100kph will be 1870 with 28s, just about where reversion will have stopped with that cam. Ok maybe mid 20s,lol.
But I degress

I'm thinking 228/234/104.... But I'm gonna convert that to a tight-lash solid; so something like 238/244/104,to get a net of 268/274/104.... Yeah that should net me about the same intake/exhaust that the current cam has, but with faster lobes, and the same overlap; but with an additional 22 degrees to share between compression and power. And Ima gonna plug 13 of 'em into extraction.
With an Scr of 10.9/ICA of 57*, that'll get me 190psi@ at a VP of 173..boohahaha
HYUP, something like that,lol.
You know the factory 360-2bbl cam totaled 240* for compression plus extraction? Same as my new cam could be,lol.
I suppose I could do that with a hydro.... but I just wanna say I got a solid. And I'm running so little preload on my hydros now that I gotta keep on top of the adjustment anyhow, so solids are no big deal to me.
But I get you on the porting.too. I just like my 230 so darn much....... Well actually I just like the sound of a screaming 360 at 7200 thru dual 3" pipes.... for 5 or 6 seconds atta time lol.
But I digress,again
