Ok Everyone, I was reading a post on here at lunch today and someone mentioned an Edelbrock C3B intake. That got me to thinking about old Edelbrock intake manifolds. I did some Googling and I’ve seen ads for the above manifolds, but never seen one in person. I realize they might be on the opposite ends of the performance spectrum, but have you guys ever used these? What were your experiences? Good, Bad, Indifferent? My interest is mostly Small Block Chevrolet, but I’d like to hear all stories.Stories of other Edelbrock manifolds would be great as well. Andy Sent from my iPhone using The H.A.M.B. mobile app
sp2p gas milage intake, made with small runners to keep velocity up but upper rpm worthless. Had one on a 400 pontiac, lasted about 2 months and went back to factory intake.....
I ran a SP2P on the SBF in my Willys 4WD wagon years ago. It was great for low RPM torque; you could stomp on it at 20 mph in 4th gear and it would just pull away up to 80; and may have helped the mileage a little. NOT a performance manifold...
Like others said super small runners, I just sold one. The C3B (and C3BX) are kinda like the early version of the Performer. The Streetmaster is an open plenum, had one on an FE 390. Yes, I know this post is old .
had one on a dodge van 318 years ago, made good torque and helped mileage a little but not a performance intake.
This is why I am happy one came with my engine. The torque will be great. My slightly over carbed 350 I had in my 54 Chevy got a solid 20 to 21 mpg. About the same a s my old daily ranger. Anything close to that or better is fine for a hot rod parts hauler. And FWIW I drive 25-30 miles each way to my day job. Many times I take extra days off on the even weeks so I do not come to town every day. Besides, country sunrises and sunsets are worth staying home
most street driven cars hardly ever get north of 3000 rpm so if i was building a "mileage" motor I would look at an SP2P and possibly Q-jet , nice quick advance curve- small dual exhaust with crossover, and possibly a bowl pocket cleanup on heads if your that far into the motor. oh ya and of course overdrive of tall rear gears.
