MaxSpool Engineering Cast Billets ready to grind

I have over 100 new UGL unground lobes cores in stock. These cores are ready to grind to your specific applications. At MaxSpool we do not produce cookie cutter, one size fits all cam, but every cam is ground to your needs, at the time of your order.

MaxSpool cams just like I used in the Predator Truck, in Rich Buckley’s Prostreet Truck, and in Project X diesel. I have over 600 ‘sold in the last 4 years, 200 of these the new Cast Billets.


These cams are wide lobe new castings with fuel pump lobes, and are drilled and taped for bolt on gear retainers.
I have over 25 different intake lobes and 8 exhaust lobes to choose from. I do lobe separation angles from 100 to 125, with lobe lifts up to .425 .
This casting is cast steel and induction harden, and the finest cast core on the market. The lobes have the proper offset to maintain factor lifter rotation.

I asked a while back if this was needed in a diesel as it is in a gasser and never got a sloid answer. This confirms my thought.

QUOTE=COMP461;979532]I also have 8620 billets and 8629 60 mm billets as well[/QUOTE]

greg, at what point is a ugl cam need to be upgraded for a billet? and explain the difference between the 8620 and 8629 billet cams. is the 8620 just a "normal" size and the 8629 a 60mm?? i'm sure a few would like to know some more info. and in depth if you have some time.

thanks:Cheer:
 
Both ate 8620 , it’s a type, imagine that . as far as when you need to go for a billet steel, in the old days there were no cast wide lobe UGL’s available, so the only way to do the really big cams with huge lobe lifts and wide LSA’s was to go with a steel UGL. I can put exactly the same lobe on the cast billets as the steel billets, so that is no longer a valid reason.
The CR engine has very little loading from the pump, as do the big P-pump. It’s not just the fact, that a CP3 pump take 7 to 10 hp to drive, vs. 50 to 80 hp for a big P-pump (13 MM and up ), but that a P pump also had violent pulsing as well. This tends to put a lot of stress on the nose of the cam.
So the time for 8620 steel is a p pump of 13 mm or above,
Extreme lifts, that put a lot of over the nose spring pressure on the cam , this from either big lobes , or big ratio rockers .
I believe that the cast billet is strong enough for the race application CR with straight cut (CR ) gear train. That said in a extreme competition engine the life span of any part is limited, steel or cast needs to be checked each season .
 
boy you guys , I havve been running 10,000 min a months on my cell. I bet that Sprint has a hit squad after me.
Dave nice to talk to you . I have your cam on the list to grind , and it should ship on monday , a magnum 207 .
 
haha
