WOW!
Did you dyno with both the tunnel ram and a single carb intake to see what the difference was?
Marlin my friend,
those are bitchen numbers! Just a "bit" shy of 600 bhp and 500 ft/lbs. I don't remember you publishing them before, so I assume they are recent. Congratualtions. Numbers like that are the evidence that somebody knows what they are doing.
There has been a lot of exchange on the DTBB lately between myself and a few others about the merits of building an engine based one combination of parts or another. I hope everybody notices you have iron heads on your motor. Would you be willing to share the details of your build for the benefit of others. Displacement, what head work/porting you've done, what cam you are running (flat tappet or roller, hydraulic or mechanical) and the cam specs, exhaust system mods, what you have done to strengthen the motor to survive that kind of power output and anything else you think was relevant to obtaining 580 bhp.
Thanks, and again congratulations.

...You Great Guys are Too kind!! Now here comes the truth; this engine was not ran on a dynomometer, the numbers are what I received after I input all the engine build data into the 'DeskTop Dyno', on my laptop. Most of you have seen the program before. It was produced after years of actual track testing and tens of thousands of drag strip 'runs', as well as real Dynomometer results on most all Makes and types of American and foreign Engines. The results are claimed to be Plus or Minus 4.% The HP with a single 750 Holley is 533. Most of us agree that near 100 HP will be lost through the Transaxle. So subtract that amount to come up with the power at the rear wheels. This Engines' internals are the same as what most all other Pantera Engine builders have chosen for their build up. For strength; Mostly chrome-moly, everything 'studded'. Roller Rockers but a flat tappet 'Comp' Cam. Ofcourse fully balanced. On and On, The list gets pretty long...It does run on 91 octane (10.5:1 Comp Ratio) with just a hint of pinging under load, which disappears when 'opened-up'. A few of You Gentlemen and Ladies, have a lot more under your deck lids! This is just something I put together with the help of my son Tristan; with all the experience I have gleaned over the years; and there have been a few. Thanks for your interest! Good times to all of You!...
Bump to the top ..... Lets see those power plant pics... Lets see your updates........

As seen in my HYPURR post. Finishing touches are to be in the next few weeks. Almost done.
Engine Bay smoothed and painted black truck bed liner. Dupilcolor Porfessional undercoat black for the chassis and wheelwells. Die Ground smooth ZF and painted Porsche Artic Silver then clearcoated. Die ground smoothed and HPC coated Performer intake (+ headers). 351 block and heads painted black. Bling added. A street motor with 400 hp.
