... wish I'd said that. Oh wait... Yes you did, I just thought I'd clarify the rod length,...I see you still have not fixed the Hemi Magnum info for the 6.4 on your http://victorylibrary.com/mopar/m-table-c.htm#Boss chart...Thank you for all the other correct info in that chart

I was looking at the rule package 4 nmca.n/a 10.5.. they call out big block Chrysler gets a weight break but yet they do not give the small block Chrysler a weight break.. so is there a cylinder head deficiency for the big block. I think at the highest level Australian Pro Stock small blocks make the most horsepower per cubic inch they are at 3 or maybe even slightly above. Sounds like a way to slip in a KB alum block and still get a weight advantage. Mega block is way heavy, KB not so much. The KOS Demon I bought from Mike Robbins had the original motor. 4.500 bore, 3.81 stroke. Huge 47cc B1 heads with 1.7 Jessels, 16-1 and 300* cam. The first time I took it into the water box it had no rev limit chip and I was used to my 416 SB, so I just mashed it in 2nd and watched the guy who tells you to go open his eyes as big as silver dollahs. Next time I asked him what he was looking at and he said it was gonna blow. So that burnout I actually looked at the tack and saw 9300 right away. Mike said he shifted at 8600 or something. I will sell it BTW.

I have a reliable method of avoiding rude remarks: stop helping. Did you think my questions are answered here? Not in many years.

When I built my first W2 340 I concluded that a 340" motor turning 7600 RPM was as "BIG" (in terms of pumping air..ie, at the same relative VE) as a 440" motor of the time turning 5800. Back it those days (late 70's early 80's) Mopar people were just starting to routinely pull their 440 wedges and swapping in 340 and 360" "giant killers"...In Cudas, road runners, I even remember a 67 Charger. at 7600 my W2 was peaking, by 5800 most BB wedges of the time were already nosing over or else they had comparatively narrow "light switch" powerbands. We didn't have bolt on BB heads that flowed 380 back then, I doubt few flowed much over 290 with a lot of port work and wafer thin or epoxied ports. Back in those days the quickest cars were BB Chevies and Cleveland fords and Hemi's but there weren't really that many Elephants around.
Air flow and efficiency determine how BIG a motor is, how much air it can move efficiently is generally more important than static displacement. And we're just talking naturally aspirated here....Turbos are a whole 'nother level and less, generally speaking smaller/lighter engines are more thermally and volumetrically efficient overall.

My goal is to be less wrong than the Supreme Court. I'm winning. To steal a phrase from virtually every judge I have seen on television series from the 60's , " one more outburst like that and I'll clear the court. ". After careful deliberation , I enjoy reading your input and addition to the posts on here. You are right a lot more than I am. ;-)

Are we done with the political stuff now? Is everyone bored and stuck inside because of the weather? People share their opinions/experiences on here, take them for what they are worth. Some are more theoretical opinion than practical application. I prefer to live by the moto that its all theory til its put into practice. Ive been in and around this business for a very long time and seen some great ideas fail miserably and some folks throw things together that have no right to even work, that work very well. We learn more from mistakes than successes sometimes. BTW Shiloh 2.55 per cube is a great goal. Build it smaller and shoot for 2.6

I have made more mistakes broke and ruined more good parts by trial and error myself sometimes I wonder what I'm doing... . 2.6 would be great just really depends on how generous the dyno is to me that day.
