Hi! I've been looking for nice, not too expensive "traditionnal" set up for my 1962 300hp 327 sbc, I already have the script finned alu. valve cover and planned to use a L79 hydro cam. I've searched here, there is a lot of infos for 327 but not many details on intake/carb setup.What do you think of an Edelbrock c4b intake and what carb would you use with that. Any other suggestions on oldschool setup? It is for my 31 model A sedan, thanks guys.
Get an Edelbrock carb and take that ugly name plate off the front of it. Other than being too shiny it'll look like an AFB which is what we had before Holley started making big carbs (dual lines). Maybe you could dull it down somehow, maybe a brush and some acid and a whole lot of care.
just run a holley(670 dual feed vacuum sec unless its a maual then run a dbbl pumper).edelbrock carbs never make as much power and there u.g.l.y.oh yeah get the original greenish gold finish they look bitchen .just sayin....oh yeah thats a good intake for that combo.i ran the same set up in a 70 camaro and it was pretty snotty with a 3:73 gear.be real nice in a hotrod.
If you were serious in 62, you'd have whatever chevy whould have put on that L-79, But that was maybe a 65-66-67 engine? We raced one (327-350HP?) that had a factory intake and a factory Holley. This was a Chevy II that was almost new at the time. Crazy fast for the era of 7 inch slicks. And still streetable. 4.88's for racing and 3 somethings for the street. with a 4 speed.
The Edelbrock C4B is a excellent choice. It is basically the same as the famous 69 Z28 factory aluminum intake. Some of the early Edelbrock intakes do not allow a factory GM HEI to clear. I would also go with the 1406 Edelbrock ... because it looks like the original AFB that most rodders would run in 1962. Edelbrocks do not leak ... and MOST Holleys do. .
A 62 300 HP 327 came from the factory with a cast iron ontake and a semi spread bore carter AFB. The secondaired where slightly largr than the primary. The intakw was different from the 220 283 & 250 327 intakes the had a rochester 4gc or WCFB carter carb.
If it is a car that will see most of it use just driving on the street, Edelbrock is the way to go. Leak free and reliable. Just because a carb has Holley stamped on it does not mean it automatically makes more power.
Whichever intake you use make sure it has the oil fill in it. I have a 283 in my TT with a aftermarket intake without it, and a breather in the valve cover. If I run it hard on the freeway I get some oil spray out of the breather on the cowl. Not much,just a few drops but it shows big time on primer.
I'm not looking for a war machine, just something reliable for cruisin down the street with some decent performance if needed, I won't go on the strip with this car.
I ran a Holley 780 vacuum secondaries on a Z28 aluminum hi-rise, my cam was Sig Hi-Flow I. It was my daily driver.
to bad the edelbrock marine carb couldn't be run on the street, the finish is nice, $100 more then a street carb, http://www.edelbrock.com/automotive_new/mc/carbs_acc/marine.shtml
I'm running a C4B intake with a 1406 Edelbrock and it runs great. Keep your eyes open, I scored the 1406 on the HAMB for $100 and it looks and runs like brand new. Scored the C4B on eBay for $50. I'll take a $150 setup that runs better than a $1500 3x2 anyday!
Given my druthers, I would run a genuine Carter AFB before using the Edelbrock knock off. That shiny Edelbrock finish screams new when you are likely trying to convey vintage. Lots of quality concern threads on here about the newer Edelbrock and Weber AFB versions. Do some more homework before making your investment. 3721s Carter would be a good choice...plentiful and reasonably cheap if the seller doesn't make the Corvette connection. BTW- I have rebuilt all 3 AFB manufacturer's units. I prefer the early Carters based on those experiences.
The winters snowflake intake 3890490 would look good, carb would be something around 600 CFM (Holley 4160?)
Search for a stock L-79 intake and a 700 holley. That will balance out real well with your cam shaft.
I ran the same engine in my trusty ol 64 'vette coupe. I ran a C-4B edelbrock intake with a 780 Holley with close ratio muncie 4 speed and 4.10 posi... One day stripped out the threads in the primary float bowl of the 780...a buddy had an old 950 three barrel Holley for 25 bucks. The manifold had the primary cut-away to accomodate the 3 barrel's "butterfly" so I bolted it on. Engine still ran great at low RPM [although that engine seldom saw low RPMs] and picked up a buncha HP in the upper RPM range...especially when uncapped. Go with the C4B.
The Carter 3720s was a factory Chevrolet replacement carb for 327 300/340 HP with automatic transmission. The Carter 3721s was a factory Chevrolet replacement carb for 327 300/340 HP with standard transmission. I would suggest whichever of the above depending on your transmission. And I would also suggest a factory Chevrolet aluminum 327 intake. Yes, you will probably spend more up front, for a more reliable product. My opinion, others will certainly differ. Jon.
If your not a race car and your going to drive the car(light to light and low rpm) years ago I took off the straight runner and 750 cfm double bla bla and but on a z /28 or copy and a 600 cfm vacum sec and electronic dist.(no points)much better and wasnt all that much slower and I never worked on it again not even plugs... my 2 cents....bob
