well now you did it, here I was pleased with my w8 s  anyone knows what price range those are in? I have seen a couple of R4 blocks for sale lately but I don t think you can stuff 400 inches into one of those, maybe there still are R3 blocks available without lifter bores

If the XR blocks can be had blank, it may be possible to build a nice BIG P-5.

the mbe heads are the aussy ones, they are very thin around the intake port,, and everyone has issues with them cracking in the bowls,, also the guy from australia doesnt want to sell them to the us anymore cause he is afraid of lawsuits
i dynoed a motor that bes had done and it was down 60hp from what they said,, dyno's are tools
everyone throws around numbers but to run fast in a/sma at about 2900lbs,, 420 inch motor,, 7.80's-7.90's would take about an honest 1000hp at 2000 ft air

The Aussie P5's are an exact copy of the Mopar P5 head, right down to the part/casting number from what I have been told. They even copied the cracks is one remark I have heard thrown around.
An R4 block will take 400ci, Aussie Pro Stock have been doing it for years.
I doubt that Mopar will get back into making them, Unless Chrysler Australia make a push for them to be produced again. The Mopar backed car over here has their engines done by Rick Watters nowadays, perhaps pick up the phone and have a chat with him.

That is a shame....
After all this time and a completely different supplier, the cracking issues STILL haven't been addressed. 
I doubt this would be allowed to happen in the world of SBX and Little Chief heads.

rick watters has a set of the newer aussie heads and they are sprinklers as well,,,, there is no metal in the bowl area
i was going to have them cast here in the us with no labels or markings, then make plastic pieces which receive in where the labels and markings need to be
it would prob be 5k for a set of castings,, not enough demand,, so started thinking of a small inch 99 hemi
what matters is the timeslip,, not the dyno number,, guys say you loose 2 tenths and some mph going to a 10.5 tire,, i dont believe that if you can still go 1.17 or so 60 ft

Hey Jeff, with the small cube Hemi99 motor, what type of bore/stroke do you feel would work. I'm assuming Pro Stock uses between 4.60 and 4.7 bores so that would put the stroker roughly around 3.09 or so.

i was thinking of using a 4.440 or a 4.500 bore,, ive done some hemi 99 pro stock before and it didnt seem to mind a smaller bore on the intake air flow,,, if the valve notches were far off the bore to allow a good ring placement,, id run a reasonably small bore to get a 3.25 or 3.30 stroke atleast
the motor i was thinking of building was going to be about 460 inches,, morgan had built one for comp that his son was supposed to race,, which he said he ran it higher and it was down about 65hp from a 500 inch motor,, he ran 6.99 with it at 2350lbs at columbus about 5 years ago in b/a
i could run a 4.500 bore with a typical pro stock crank of 3.625 stroke and get 461 inches,, my car would be about 3200lbs in a/sma,,, id need to make about 1200hp to be real fast,, with it being a wet sump,, you could just get a used pro stock motor and sleeve it down then get new pistons,, though i know from experience that in a motor like that the sleeves will move around alot

I have had it in the back of my mind but I really don't have the coin for the rest of the engine!
As Jeff also pointed out, the demand would be pretty low and it would really be a labour of love. I don't have a casting lying around to get 3D scanned, and I would really have to work in with someone like Jeff, or MBE or CFE or CFD to get the ports and rocker geometry correct etc. There are four cars in Aussie Pro Stock running P5's currently, plus buyers in the US. I guess the other thing is if they took off I doubt I could keep up with the demand, I do my best work after hours, lol. It's been a dream of mine for sure

Wow, I'm surprized that it only fell off 65 hp with the small bore. You would think valve shrouding would be a big deal? I wonder if they had to use a different cam profile?

when i seen larry run 6.99 or whatever it was it was with a small motor that he had done,, i was told 470 or so,, i heard other details from jeff taylor and joe tueton as they were talking to larry about it all
the heads i did for morgan flowed 570,, i flowed them on as small as a 4.500 bore and the flow did not go down much at all as i recall,, though was a few years ago that i did them
i think you can run a bore as small as 4.500 and get it to fit,, ill have to look at it again,, but im pretty sure,,, you dont need a 2.550 intake valve to feed the smaller motor,, so you could go 2.450 and still get 540 probably,, that in itself would let you run a smaller bore,,, the exh might need to be moved off the cylinder wall for a smaller bore,,, which could be done
