Thanks for the kind words on the 514 I built for Joe Cloutier's SPF. That is the Blue Thunder intake. I opened up the ports to match the aluminum CJ heads and machined a half inch out of the plenum dividers. The carbs are two Holley 3310 750cfm vac secondaries with the choke horns milled off. Jetting is 68 in the primaries with the stock plates in the secondaries. Power valves are 6. 5. # 32 squirters. The old cam specs are (mech) 259/266 degrees @ .050" with .606/612 lift 114 lobe centers. The engine idles at 850 rpm with 11 to 12" of vacuum. It drives like a stocker, idleing around town without a care in the world. On the chassis dyno, after a cool down and jetting the carbs to get a 12.5 to air/fuel ratio, it made 537 hp @6200 rpm. At the rear wheels. We have since installed a bigger Flat tappet cam 262/270 deg @.050 .650/.650 lift 110 lobe centers. We are hoping for 550 to 560hp at the rear wheels. Too much horsepower is just about enough!
I have a spare brand new Blue Thunder 2X4 intake for sale if anyone is interested, e-mail me.
