I just received the dyno results from an engine I had Hughes Engines build using one of Brandon's 440Source custom stroker kits with the balance of the parts, components and know-how coming from Hughes Engines.
The basic build; 4.15 superlight 440Source crank, Ross custom lightened and coated 30-over zero deck height pistons, Gapless rings, 440Source premium 7.100 rods & coated clevite bearings, Hughes Prepped RB block & Indy Ez heads(non-Max wedge port)with stage 2 Hughes porting and prep, titanium retainers, Hughes Hydraulic roller cam and valve train, Edlbrock aluminum six pack mainifold with Hughes deep porting, Promax rebuilt Holley mechanical carbs with choke horn milled, Promax billet metering blocks and some skillful carb tuning by Hughes.
This motor is not going in my daily driver, consequently I figure I'll be lucky to burn 30 gallons a month through it. I didn't want to run it on the straight 91 octane pump gas we have here in California, and planned on feeding it a mixture of 91 pump and race gas(for off road use only of course). I figure it comes out to about $1 more a day to run the high compression, and I love the snappy acceleration and sound it gives a motor.
Here are the results. It twists over 600 foot pounds of torque above 3000 rpm, peaking at 684.5 lbs/feet of torque at 4600 rpm and 681.1 horsepower at 5500 rpm
Once I finish installing it in my old 1970 4-speed 'Cuda, it should be a handful on the street. I don't think I'll make it past a first run or two at the strip because of the lack of a roll cage.
