Default Very Cool Man-A-Fre 4-carb Manifold - 427 BBC

I was goofing off on Ebay and did a search on Man-A-Fre....
I've seen the 4- 2barrel carb set ups for Small Blocks but never a
Big Block.... ad says the guy has the linkage too..

i had a Man-A-Fre on my '65 327, once-upon-a-time. it was the greatest thing since FI, without some of the hassles that goes with FI.

funny thing is, i traded it for my first FI; i wish i still had it, but all the units i see selling on ebay are VERY expensive.

i even wrote to Man-A-Fre recently (they are still in business, making off-road parts for Toyota's (i think)), but i was told they scrapped all their molds a while back....

I havent thought about that name in years..a real blast from the past. Those manifolds looked prety hot back then.

Default BBC Man-A-Fre Recent Build

Just finished a 396 BB with G.M. Aluminum heads and an Engle solid lifter setup. Customer requested the "Man-A-Fre" be used. Unit performed flawlessly.

The purpose of this build was to use some "old-school" components but combined with today's technology, the PCV setup.

As you can see from the photo below it's really quite impressive looking for a multiple carb setup. If you look closely you can spot the "Moon-Eyes" V/C breathers.

(Add) Unit made over 500 HP on 93!

Thanks, Gary in N.Y.

P.S. There was much add'l engineering done on this particular build. As I stated above, the customer also requested us to use a 2006 Vette "hidden" PCV system. You cannot see from the photo but it has the entire system below the intake manifold. Took some hours of machining but it was finally accomplished. It is 100% functional AND 100% "invisible". Not a single visible "hose" or line connected. Gets fed directly from the "valley" into the underside of the plenum.

John Milner ran a Man-a-Fre back when he had the bitchin'est set of wheels in the Valley.

I seem to remember that Man-A-Fre intakes had a bad rap for destroying intake valves?

The carbs (frozen) are listed separately

The seller also has an interesting small block item - Ansen main straps?

Anyone remember how these work (did they help)?

For a super double-throw down setup you could use a Schaller quarter speed cam with it

Bill - It was a cam, not a distributor. It had double lobes. The special timing gear compensated for the slower turn of the cam. Like the Man-A-Free, it too was more theory than reality as far as improvbed performance

actually, it was a special distributor too, the rotor had double ends and dual contacts and the cap had 2 rotor contacts and dual coil towers and used 2 coils because the distributor only turned half of it's normal speed and therefore had to fire twice as much.

I remember it being on, "The fastest car in the valley" and weren't they made in Atlanta, GA ?

at least that's what was cast into the adapter manifold... (and i believe misspelled...)

Bill - Maybe they had a couple of set-ups, but I don't remember the dist being different. We bought a short block that had that cam and don't remember using a different dist, but then that was over 40 years ago and I'm sure I've forgotten a lot of other stuff too since that time.

Either way, the cam set-up really made no sense as far as gaining anything. We actually ran better when we pulled out the stroker engine the cam was in and swapped it with a stock 327, 340 hp short block ,

the cam that i remember seeing had roller lifters and supposedly the theory at the time was that because of the slower rotational speed of the cam, the lifter inertia would be less and there would be less likelihood of valve float....
Bill

it was neat to look at though....

PRW is making both girdles and straps currently for main cap bolts.

they work, they strenghten the bottom end main cap studs in a
similar way that a rev kit strengthens your rocker arm studs...
pieces of metal that tie the studs together so that there's less flex...
.... stiffening the bottom end.... you get more support from a girdle
than a strap... not nessasary unless you're going to make over 500hp.
but deffinately cool to see the old Ansen stuff out for sale...

PRW stud girdle....



Straps usually just tie 2 studs together .... not all the studs like a girdle.
A Girdle would be something you could use instead of drilling for Splayed Main Caps on a 2 bolt motor.
