All hail the BBC.

Drop a nice 850 on there and see how much it wakes up at WOT. /forums/images/graemlins/eek.gif

600 cfm is too small for a 454 in my opinion. I'd say 850 cfm would be closer to what it needs.

I second that! BBC's need lots of air to breathe, so getting a larger cfm-carbed would be the hot ticket here. /forums/images/graemlins/thumb.gif

Ha! You should have seen Shawn lift the front tires off the ground when he took off in the Potent Rodent Wednesday night! /forums/images/graemlins/eek.gif 496 cubic inches of port fuel injected whoopa$$. /forums/images/graemlins/thumb.gif

And yes, a 600 CFM carb is way too small for a 454. /forums/images/graemlins/frown.gif

 

[NITRO]

well...i bought the 600cfm for the 350....well that engine went and i got this 454 and couldnt just let my carb sit there and b trash. it runs great...enough for what im needing at the moment. but, my gas milage still sux rhino cock with it. so id hate to see what an 800cfm would do to gas milage

Yeah the milage might suck, but ain't it fun watching the tach race the gas gauge!! /forums/images/graemlins/eek.gif

[/ QUOTE ] Shitty gas milage ??? Welcome to the reality of the BIG BLOCK. But with that kind of raw torque, do you really care about gas milage ???

 

[sled_dog]

If the gas mileage is too bad for ya I will trade my 355 with ya /forums/images/graemlins/smile.gif. Wish I could find a nice BBC to build just haven't located one. I would love to call my truck a BBB, Big Block Blazer /forums/images/graemlins/smile.gif.

I'm afraid of opening up my BBC too much.....I dread the sound of TH350 parts disintigrating. /forums/images/graemlins/shocked.gif

 

[sled_dog]

I woudl be if I were you too, got to love an SM465 /forums/images/graemlins/smile.gif

 

[HarryH3]

Having the wrong carb can contribute to lousy mileage. I had a '79 4WD Dodge van with a 360 several years ago. It got a whopping 6 MPG with the stock 2 barrel carb. /forums/images/graemlins/eek.gif I swapped on a 600 CFM Holley 4 barrel and mileage jumped up to 11.5 MPG. That mod paid for itself pretty quickly! /forums/images/graemlins/thumb.gif

 

[88Silverado]

The 1406 is a great carb.
It will run just fine on the BB
You could find an old Quadrajet with small primaries and BIG secondaries which will give you good mileage until you stomp on it, then you can watch it suck leaves and small animals off the street and that bitchin ROAR /forums/images/graemlins/thumb.gif

It's good that you are aware of that..I had a TH350 behind my SB for alooong time. Never had a problem. 3 weeks after I swapped the big block in, it puked it guts out..That sucked and I didn't want it to happen again...So I swapped in a TH400..That one lasted about 2 weeks before I broke the case.. /forums/images/graemlins/eek.gif Sooo, in went the SM465 and I haven't had a problem since...Lovin my BBC and SM465. Only way to fly. /forums/images/graemlins/thumb.gif

Can't wait to put the BBC in my K5 someday and be right htere with ya /forums/images/graemlins/smile.gif

 

[Hossbaby50]

Harry, Shawn's truck lifted both front tires at the same time off the ground? I wouldn't believe it on any other fullsize K5 with 38's, but with his I can. If he did lift both that is a neat trick I will have to see some time. /forums/images/graemlins/thumb.gif

 

[sled_dog]

if he can lift just one tire, say driver side front that woudl be more interesting to see in my opinion. Be like one of those big rig tractor pullers where the driver side front never touches the ground because the torque twists the frame.
