Carburetor woes

I think I'd be lucky if I was putting out 200 hp. It's a 304, stock as far as I know except for headers/dual exhaust, edelbrock performer intake, holley 670 carb, and open-element air cleaner. If I had to guess and it's just a guess, I'd guess I'm making maybe 180 hp or so. Just a guess...

You're right, and Holley made all the double pumpers the same from 390CFM up to the new 950CFM HP models which will feed a 1000+HP engine. In this case it is necessary, but not for a 304 probably making 200-250HP.

Yeah, I know they are up to 1250CFM, but I wasn't counting the Dominator carbs since they use a different fuel line than the "regular" double pumpers. And yeah, some guys even use 1/2" lines for drag racing these days, but like I said, it is not required for a 200-300HP engine.

LMAO

Yup, and I said fuel line, referring to the dual feed line that feeds both bowls. The spacing between the bowls is different on the Dominators. Sorry if I confused you on that, but I think we were referring to 2 different things here.

heh heh. I swear I wasn't trying to be funny, just trying to give an accurate description of the engine. I was trying to say that nothing really radical had been done to it. Factory cam (I guess), hasn't been bored out (I don't think), etc, etc. Looking online I find:

AMC 304 1972-'78 Bore x Stroke 3.75" x 3.44" Displacement 304 (4.98L) Compression Ratio 8.4:1 Horsepower (gross) 150@4400 Torque (gross) 245@2600 Main Bearings 5 Valve Configuration OHV Fuel 2bbl

So 150 hp from the factory. I figure that between the headers/dual exhaust, intake and 4bbl carb and accounting for it not all being set up optimally that 180 hp is a reasonable guess at what I'm making right now with my "stock" engine. :-) Source for above data:

I'm flattered by that statement, Bill, but there is at least one reason I couldn't blueprint it for more than a horsepower per cubic inch, that being that I don't know what I'm doing well enough to do that. :-) Hell, I had to ask for advice to confirm my suspicion that my float level was set to high on my carburetor, and it took me WAAAY too long to track down the vacuum leak that was causing me so much trouble after the intake/carb swap.

Oh yeah, and I put one of those Davis Unified Ignitions on it too. Maybe that gives me a few more hp but I'd guess I'm still at 200 hp or lower.

Or, with a shoehorn and $15,294 you can have 525 hp

I'm the guy who was complaining about how expensive an $80 fuel filter was, remember? ;-)

I think you mean "ALL y'all" as in plural.
