This is my setup: 408 stroker... ported Eddy Performer heads, intake manifold runners were opened (a lot) to match the heads (really flows)...blah-blah-blah.. aaall the hot do-dads we expect. She dyno'd in at a surprising at 543 hp 572 tq, redlines at an easy 7000, shift at 6600 (4-spd car). The pics below were taken while I was still installing the engine, but does show the carbs. As you can see mine is kind of a Frankenstein as the carbs are sacrilegiously from a 427 Vette with mechanical progressive linkage (no vacuum who-ha). That's right, Chebby crap on my PAR... but what can I say, they're awesome. The 6-pack was a pain though, no doubt at all, but once properly set up (dyno), they've provided PLENTY of smiles for quite some time now! But it's weird... these 6-packs: they perform kinda like a 2-stroke dirt bike..ie: Fairly crisp throttle with 'fair' performance (center carb) up to the point where, if I press down a tad more, the linkage will pull both end carbs into the flow and whoa, now we're having FUN! Immediate BIG rush... even when you just wanted a little bit more, you get a LOT like NOW.... which took getting use to (and learning better throttle discipline). You want 6 barrels, just press and there ya go! BUT having run it for a few years now I'm not sure I like it that much anymore. The center carb is smaller than the end carbs (cfm), and with the big stick this engine has, it seems to hold it back some. Cam is a custom grind (solid lifter) with only 20 degrees overlap, with BIG numbers on lift/dur.... so I can snap the throttle(s) and I've zero dead spots, or hesitation... she just pulls. I'm planning to pull this setup this summer and install my Eddy Airgap and Holley 750 HP Street....just for a change. I may have to opt'd for an bigger carb, but we'll see... Anyway.... Just sharing a little stuff with follow motor heads. Good luck.
