Just got 86 blazer, need help, got alota ideas

If you know Holley carbs then I suggest going Holley. I definately make way more power with my holley than I could with a q-bog. I think they are the way to go.
 
So would a 650 holley be ready to go out of the box? Im in MS, at sea level so I figure it should ready to go huh?
 
Whatever carb you go with will need some basic tuning or adjustments to get it just right for your engines needs. You should find someone in your local area with carb experience. It's hard to try and tune it over the net, really has to be done in person.
 
I'd jsut throw it on out of the box and see what it gets you. Then tune from there. Most likely you'll have to change the accelerator pump cam to a bigger one to prevent the off idle bog.

Also if your engine still have the factory intake manifold, scrap it and get a performance manifold that is designed for a square bore carb to match the holley. You can run an adaptor but its my personal opinion that they suck by preventing max air/fuel velocity into the manifold.
 
LOL! I know what your saying but i cant help it, its in my blood! Hell i already ordered, ceramic coated long tubes, holley blue electric fuel pump, manual block off, new seats, new steering wheel, new oversized radiator, flexalite electric fan, all new guages. Still deciding on the carb, lift and tires.. I have decided, not to go over about 6" inches lift and 37" tires till later on and i get 1 ton axles..

If your going to go thru all the trouble with a holley blue and reg. you might as will go all the way and get the Edelbrock manifold RPM and holley Double pumper. I would go 750cfm just incase you want to do a cam swap or bigger motor in the future.

Yeah my uncle is awesome with carbs, he has been building drag cars for years. Ill have him look at it..

Yeah i got a eldebrock performer intake, headers, all the bolt on goodies.. Would you suggest vacume or mechanical secondarys on that holley??

Which carb is better for my application, been reding up on all of them and cant make my mind up... A regular holley 650, a truck avenger 670 or street avenger 670???
 
you can lead a horse to water...

I've been working on Holleys for 30 yrs, and contrary to what you want to believe, for a stock to moderately modded motor, they can't touch a quad...

oh I havent ruled the quad out. I got a guy on stand by ready to build me one just for my engine setup. Also I had a quad 800 give to me that i will certainly try. But "most" of the guys on here appear to be running holleys. so im trying to get a good idea on both. But no dont think Im not picking up what your puttin down..

not even close...Quads by far out number Holleys on this site... I was trying to avoid this, so as to not offend the Holley guys.... I ran many back in the day, and still see them occasionally on the boats, mainly ski boats...

but the huge number of production vehicles, including just about EVERY carburated boat motor in history run quads... Holleys have there place, mainly the track..

if I'm building a 1000 hp motor, I'll run a Holley... for any motor that isn't crazy ponies, it's a quad...
 
Ryoken..Or anybody for that matter

What carb has better of camber performance? The truck avenger or a quad?

I was dead set on switching my edelbrock 600 to a truck avenger seeing as how its supposedly built specificaly for off camber wheelin. But now hearing about the quad it got me thinking.

Not trying to Hijack, but this follows topic and will probably help out our new friend as well.
 
no carb out can compare to a quad off camber, it's inherent in it's design..
 
huh, good to know. Now i want to do nothing but learn all i can about carb design to figure out why.
 
it's the bowl design and how it feeds the idle, primary and secondary circuits...
