Here’s an example of how the $1675 for the manifold porting could be used in a different way.
You think the current heads are “too big”?
You can buy some std port stage 7’s(which is just a Victor head) from Mancini for $1300/pair with valves. You can reuse all your current hardware and rockers. Headers will fit. Sell your current heads and valves to finance some prep and porting....... and still have some left over.
Then you’d have std port heads, and that M1(or TF, or Victor) would fit just fine.

How about 4.625 bore with a 4.650 or so stroke to make 500 C.I.? I hear and see rumors about P.S. engine specs, me thinks you would have to be on a P.S. engine team to know the real specs

that would be a 625 cab. a 4.7 bore with 3.6 stroke would be 500.

I agree, more cubic inch is better, but seems it is better to get there with the bore. I think since the 530 blocks have less core shift than the earlier blocks maybe I could take the bore out further than the typical 4.375. Anyone know how far the 530 400 blocks can be bored and still have plenty of meat left in them? Can they go 4.500? 4.400? 3.91x4.500 is almost a 500ci, 498.

I've seen massive core shift in some of the 400 block castings I have tested, including both versions of the vaunted "230 and 530" blocks Have yours sonic tested by a good shop first before going bigger than 4.380 The thickest ones I can remember using had the thinnest major or minor cylinder wall thickness of around .160 somewhere from the top of the cylinder wall to the bottom of the water jackets before boring I would love to have a 400 block (I have two in stock now that need sonic testing ) that had at least .220 before boring as the thinnest part of the cylinder walls I bought one 400 block from Andy F several years ago that only needed .007 clean up to get the bores straight, it was a cold weather early block that had been sonic tested. I retested with my Dakota 1000 sonic tester and the thinnest wall I found was above .160 I raced that motor four 4 or 5 yrs and took it out of the car last winter, I'm hoping to get it apart this winter to freshen it
