holley 4175, E qjet replacement

[KansasTwister]

How do you guys like them? Im replacing a motor on an 86 and planning to do away with spark control (no emissions here) and was going to get one of these spreadbore holleys on a edel preformer manifold i already have, and just do away with the headache of an electric carb. They use the same hard fuel line, same electric choke, even has an idle air solenoid.

Also, you can change the jets on these right? its not one of those cheap pos's you just bolt on with no adjustment, and it is a vacuum secondary for the 700r4. Supposedly a bolt on and go kinda carb. The motor going in is from a 75 k5 nonemmisions 350. Just let me know your thoughts guys.

I just put one on my Buddy's Cadillac, it works great, easy bolt on. The bowl did get close to one of his A/C lines though. You can change the jets just like any other Holley

I had one on my camaro in high school/college and it ran 14.20s (ok for full exhaust, street tires and 3.08s). I loved it. Don't know about off camber though.

offroading you mean? this k5s just a street vehicle, not gonna see offroad time very often, too clean of a body. So no worries there.

First you need to take it too Tuttle creek, 2nd I meant off camber. Off roading on the flat any carb will work, I meant off camber/at angle etc.

I ran a Holley spread-bore replacement on a 454 many years ago and it was great. The secondaries tend to bog unless tuned but it was still way better than OEM
