Anybody know where the Cad Man Is lurking? Would like some tips on a camshaft.
Look on Facebook and join the 472/500 group..
Cad man and scott hatch have cam wars on the 472-500 fb page. Julius advocates narrow LSA and Scott Hatch likes wide LSA with the cam advanced toward a 108 or so center line
But Cad man is on there and he will answer you.
I understand the war on LSA. Narrower LSA means more overlap and lumpier idle, but makes "YAHOO" on the big end. And scavenges the cylinder faster. But since I am going to run a blower, don't care about idle. Just haven't decided on stick or auto yet. Yes I know a stick will make things more manageable on the street or at lower rpm. Not that I would take a 2200 lb. car with 500 inches of blown Cad on the street
More stall speed in the converter will take care of idle problems. I personally have not heard about a stick that will hold together behind a well warmed 500. Greg Surfas
Was thinking an old BW Ford ST-10. From a big block Mustang. Can get the trans. for free, also have a Pont. can.
The only transmission an old big block Ford Mustang had was a Toploader 4-spd. Even the big input transmission will not hold up to the torque of a 500 Caddy. I suppose a T-56 Magnum is probably the only shiftable pattern street transmission that could handle it. If racing them a Liberty clutchless is the way to go or a Lenco.
I thought so. But my old bourbon infused brain doesn't work that well anymore. If I remember incorrectly, the top loader MAY be able to handle it. It seem that the "SKAIRLANE" has been running for quite sometime. In the 8's with a 4speed and a SOHC
I'm not sure what kind of torque a SOHC makes. But it has to be huge. Yes, this car is real I've seen it. Damn thing bounces all over the track.
A 427 Cammer
"Ford's seven litre Cammer SOHC V8 engine showing cam, rockers and timing chains
The Ford single overhead cam (SOHC) 427 V8 engine, familiarly known as the "Cammer", was released in 1964 in an effort to maintain NASCAR dominance by seeking to counter the enormously large block Chrysler 426 Hemi "elephant" engine."
"The engines were essentially hand-built for racing, with combustion chambers fully machined to reduce variability. Nevertheless, Ford recommended blueprinting before use in racing applications. With a single four-barrel carburetor they weighed 680 lb (308 kg) and were rated at 616 horsepower (459 kW) at 7,000 rpm & 515 lb⋅ft (698 N⋅m) of torque @ 3,800 rpm, with dual four-barrel carburetors 657 horsepower (490 kW) at 7,500 rpm & 575 lb⋅ft (780 N⋅m) of torque @ 4,200 rpm. Ford sold them via the parts counter, the single four-barrel model as part C6AE-6007-363S, the dual carburetor model as part C6AE-6007-359J for $2350.00 (as of October, 1968)."
Probably very little that is stock about that 4 speed.
You've got a point there.
If I go to the local Ford dealer, can I buy one for 2300 semolians? Maybe get it cheaper through the shop?
The inflation factor from 1968 is about 10:1. Would probably get the equivalent today for about $25K. In 1970 I bought a complete Chevrolet L-88 short block for $235.00. The heads with the valves were an extra $150. The good old days
D,Brother D, Was the cam changed in the engine with 2 carbs? Kinda curious, The reason I asked, That motor will really turn up the rpms@7k. Summit referenced a 750 Holley carb for my motor way back when. Julius shared with me a simple option. put a bigger carb on your motor, do the proper tuning and see what a difference it makes. For me it was a different car! night and day difference. my boss at the time had a 850dp and changed some jets a few timeson the 780 I have. that was a noticeable difference. but still not even close to the 850dp.
with all things equal in the ford motor. except the intake and carbs, then more air,fuel=power.
I don't know if Ford changed the camshaft with the addition of the second carb, but my SWAG would say that they did. That guestament is based on the major pickup in torque over the single four barrel. The horsepower increased by 41 hp just 500 rpm higher while the torque went up 60 ft. lbs with a 400 rpm increase. I don't think those numbers came about just with the better air flow - unless there had been a shortage of plenum before. Hmm, like was said, it's a guess.
