I think it's because it's such a small cam and the torque peak would usually be around 3500 with that size cam, but who know's? Lets see the dyno sheet

Why you ask... well because i spend so much time and money on stroker sb making only 500-550 hp and this one gets 600 with 9.5-1 comp, super small cam, 354 cubes and at 6000 rpms.

im not BSing here

Monster numbers..........even if the dyno were 10 % on the hot side , I'd be impressed.
The stock bottom end on those was a weak point as I recall.
I had three early Hemi's of varying sizes in the early 80's and they all had spun rod bearings.
I know that tons of improvements have come along since then , but with that small of a cam , I couldn't see those numbers coming from any 354 inch motor without a ton of massaging or a dab of spray.

Actually, the stock bottom end is quite strong. Big rods and a forged crank. At 600 hp you will start to see some cap walk, unless a main cap girdle is used.
As for what this combo made for HP....no comment.

I said the same thing when I heard the cam size when they were building the engine. I maybe off on the torque number, I was going off my memory but I know the hp is correct. Apparently size doesn’t always matter, all joking aside Hot Heads (http://www.hothemiheads.com/) knows their stuff when it come to early hemis. When NVR and Hot Heads were putting the package together, they said 500-550 hp shouldn’t be an issue but they were both concerned with the valve train robustness.
I’ll see them next week and ask for a copy of the numbers.
I think its hilarious having these old blue hair guys showing me how it’s done..... no head flow numbers, intake numbers, no cnc porting, just a heck of a lot of experience.

Don't give any credence to the doubters, none of them have probally never seen or worked on a early hemi likes your dads A hemi is a hemi, the head is the key to making power on any engine, flat head single cylinder lawnmower motor or a Ferari V12 The early hemi heads where not designed to be raced or make a lot of power up above 3000 RPM, the 426 head was designed with racing involved The early hemi heads and rocker gear is a better design with the combustion chamber centered over the cylinder, unlike the circumstances the 426 Hemi heads where designed under Replys ?
