Hemi wins Engine Master's Challenge

[Noohki]

If you haven't seen it yet, check out the "2010 Amsoil Engine Master's Challenge" in the February issue of "Popular Hot Rodding".

The winner is B.E.S. Racing Engines using a 417 cid Gen3 hemi using 5.7 Hemi cylinder heads. They made 700 hp @ 6500 rpm.

Most of the competition were using aftermarket heads and blocks.

There is some info at http://www.popularhotrodding.com/enginemasters/1010em_2010_amsoil_engine_masters_challenge_friday_updates/index.html

intresting. What year motor were the heads from? 09 and up or 08 and down? I want more details on the build. But seeing how I'm on my phone it's hard to see all the info on the website. I'll look tomarrow when I have time.

I have not read the whole article yet, but there were a couple more Gen 3's in the competition as well.

The article doesn't mention what year the heads are. They do say they used 2.18 Ferrea intake valves and 1.60 Ferrea exhaust valves; and that they used 1.7 Jesel rockers.

I too, would like to see a lot more details.

The new heads are 20CCs smaller than the 08 and prior head, so compression is real high...

thata assuming the used a stock piston. so they could have compensated with the piston choice. the heads are also a closed chamber design, and outflow the older 5.7 heads and almost flow as well as a 6.1 head.

Ross pistons were used for the build.

In the current issue of Pop Hot Roddin' they say they used "late model 5.7 Hemi heads". So, I assume they are refferring to 09+ 'Eagle' heads. They also mention that those heads were flowing 360 cfm on the intake... Good read on a really trick build.
