Reached a long awaited milestone in my Hemi build this week. After collecting parts and slowly progressing through the build for the past year and a half, the engine finally found its way to the dyno cell last week. I had hoped to run the engine in 2012, but the schedule did not work out. I am now targeting 2013 to have engine and car at Drag Week.

The engine is a normally aspirated 588 and is designed for extended street use. Valve lift is under .690, cranking compression is 160#. Dyno headers are 2 1/8" Super Comps. All testing was done with pump gas from the local Speedway gas station.

More compression, cam, headers, and a different intake would probably improve the power, but I wanted reliability and a lower scoop profile for the street.

The engine is going into a 67 Belvedere chassis. I plan to run in the Street Race class, big block normally aspirated category.

That is a nice combo! Are you allowed a tanker trailer with fuel? Curious what lifters and valve springs you're using?

I believe you could have made more power with a smaller port. The velocity must have been low.

Yep, it was way down on power due to the ports, probably would have been 1150 instead of "only" 1054.

Scott I really hope you make it out for the 2013 DW. I do have a question about your AWESOME HEMI build, How much cam are you runing? Do you use pushrod oiling with the Barton Rocker Arm setup? If not, how well do they live on the street. The only reason I am asking, I was going to buy a used setup from a SS racer and he said they were not recommended for long runs or street use since they had such limited oiling.
Thanks for the input and Good luck.

Lifters are Comp 98829's. Heads are Stage V Millenniums. Cam is about 280 @ .050 at about .685 lift on intake. The spray oiling remains to be proven on the street, but I think 572Charger has used this setup quite a bit on the street with no problems. There is really quite a bit of spray up in the valve covers at pressure. I'll be watching it closely while driving the car next year during testing, if necessary we will add some oil to the top end, either via pushrods or more spray.

I apologize, I realize I misread the chart. I saw the "821 HP" and thought it was the peak HP. My mistake.

Has anyone heard any rumors on where Drag Week will actually be held next year?

I mis-read the chart also lol, those are great numbers, that will be an amazing pump gas street motor.

With the design of the upper portion of your intake, will it need any kind of blow out window?
I just wondered as it looks similar to some of those intakes that have a tendancy to go boom during fire up, unless its different than what I'm thinking of.

Wish I could afford a car that an engine like that would work in. Lots of details to work out on an engine like that...really cool..Very sweet build for sure. How many cubes is that thing that you are running two SV1's?

Also, I know Jim Paranis (572Charger) personally, and he does drive his 605 on the street....
