okay... i have an edelbrock #1904 on a 350... the diagram under the hood is for a 305 if that matters, and the emissions equipment has been removed from my engine...
as i was reading on swervin's site, this carb has a dual pump so it can draw more fuel/air(?) as it needs it, and this is controlled by the temp sensor in the thermostat housing... i don't have that sensor, just a regular water-neck... i assume it is a vacuum type thing going on here, and was wondering if there is another way to run the lines, or if it is better to have the sensor and go with that setup... right now the distributor line is run to the port labeled 'H' on the carb... seems to me that my truck feels a little hesitant... could this be why? what does the 'H' on that port mean, anyway...? any help is good help! thanks, jeremy

Re-read the article. 1904 does not have dual pump. As far as the distributor advance, You need to decide of you want ported or manifold vacuum. There are pages and pages of debate on this. Factory on my 85 was manifold which means vacuum from the carb port at idle.

oh... i missed that...
just read it again and that makes sense... the original waterneck had the sensor, but nowhere for it to hookup... thanks...
now, does manifold vacuum make a difference as opposed to ported vacuum? which way is better suited for faster acceleration? thanks again... jeremy
