Something I find completely perplexing is none of the gen 3 flow numbers that come from this site are even close to the numbers from the LX forums. All of ours are also always very similar, sometimes identical yet over there they are also very similar to each other from various vendors.
This is not the case when I go to the LS tech forums. I port alot of LS heads and every time my flow numbers are right in line with theirs. Even aftermarket. A TEA cnc square port flows 370, i get 370. AFR 225cc goes 325, on my bench the number are almost exact. Its always consistant
I called one of the hemi vendors that nobody likes, Inertia. He would not talk flow numbers and I know why, because all of the other hemi vendors are full of crap and I think he argues with them over there. Im not on there enough to know what the deal is though

My cnc'd 6.1's don't have a lot of meat removed except guide transition and roof then some more on the short turn. Pretty conservative program it looks like.
Mopar to the bone!!!

Ok i have read this entire article. questions
1. bore-stroke of the 5.7
2. bore-stroke of the 6.1
3. bore-stroke of the 6.4
if going to bore-stroke the engine, would the 5.7 be the least expensive(it will be in the car)?
can the early heads on the 5.7 be ported to the size of the eagles?
I'm confused on the cams working with the older vs new head? machined differently? My project was to find an older Challenger then install the 6.1 engine,($5200.00) now it looks like the 5.7 would could be made up just as well, later upgrade to the hellcat supercharger. This is all new to me so steer me right please.
1 3.92 x3.58
2 4.055x 3.58
3 4.090x 3.72
4 bore and stroke will be cheapest depending on which block is cheapest.
yes
don't know about finding a new 6,1. good luck and jump on it if you find one.

"don't know about finding a new 6,1. good luck and jump on it if you find one"
can get a used one with 59,000 miles for $5200 out of a Charger with accessory's and boxes or one for $4,000 with 100,000 miles. maybe sell the 5.7
Nigel has 1 left. Less money than used.
