thanks for your time.-Dave

 

What will the engine be used for? Car, Truck? Off-Road,Towing, Daily driver, or Street Machine?

 

Rochester Q-jet

 

my bad sorry!

truck

1986 chevy sliverado k30

little bit of everything, that is probably a horrible answer but i use it for work towing drive it daily take it of road, just everything.

 

l agree, get a stock replacement

 

why a stock replacement? wouldnt aftermarket be better?

i was thinking edelbrock?

 

i hear good things bout the Q-jet from some of the older crowd I know. It's something about it's more simple to rebuild and the jet's and floats are simple to change for more CFM. Something along them lines anyway. Personally, I'd go with Edelbrock. But I prefer TBI over all of it, including my 07.

 

The three to five horse gain isn't worth the mileage drop.
They (edelbrock, holley) are finnicky and constantly need adjusting.
I've never had good luck with them.
Please note that this is simply my opinion.
I like the simplicity of the Q-jet.




Edit: I just re-read the thread. You might consider a holley truck avenger if you get serious off-road. I ran one and didn't like it, but I didn't like any carb off-road, that prompted a TBI swap. An option you might consider if you can afford it.

 

i have not purchased a new Qjet in about 25 yrs. could pick up a BB Qjet new for under $100 and flowed 850-900 cfm. at WOT and 350-400 cfm. on primaries.
what a Edelbrock cost and a Qjet cost now i do not know. i have gotten over 100k on Qjets before needing rebuilding. and any parts store stock a kit for it... i don't know maybe just getting old, and hard to think in the 21st. century

good luck on what ever you chose
