Why do you think these carbs are bad?

BUIZILLA

I had a pair of these, and NEVER did like them... hot starts was a real b1tch sometimes.... fattened them up to 70/74 jets and then they ran *okay*... still never liked them... i think the needle and seats are also too small...

Fix, you don't think Demons will be too much on a small block? I would have recommended a set of 4150s - 750 cfm.

I always had bad luck having BGs provide too much fuel to small blocks that ran less than 400 cubes and less than 350 or so Hp. I had a 410 stroked small block that I thought was big enough for a 750 Demon, but I had to send it back to BG twice to lean it out.


*** On a side note, has anyone had any trouble with BG lately? I sent them a damn fuel pump almost a year ago and they still haven't sent it back...

i run a 750 on my 355, it is far from stock but it works vary well,on his set up and him being at sea level it should be fine..i have always run 750's on all my 350's chit i even ran one on my old engine in my donzi which was a 312 cid but i had fuelie heads that were ported and polished and a 510/510 L 280/280 D on a 106 lobe center solid lifter cam...i would wing the crap out of that engine..

His carburetors have vacuum secondaries which i think is where he is getting his lien condition along with the small jets..

all honesty,,in my eyes that was the worse carburetor that Holley ever made..like buiz said they tend to run on a lien side..

WOW... Just frickin'... WOW...

That fuel pump I sent back to BG... Guess what??? I was RIGHT!

They sent me my fuel pump back today, unrepaired, with a cute little message saying the following:


Frickin' BRILLIANT... Now I have a fuel pump that needs a motor that only Barry Grant manufacturers and they're done... Grrhhh.... I'm gald I switched to Areomotive pumps when they took too long to get back to me in the first place.
