I go to order my cam from C O M P and they tell me its made of austempered steel and I should get a distributor gear to match.

I thought I could just slide in a OTS cam stab my dizzy and go why are they recommending I change my dizzy gear and talk of this fuel pump pushrod.I'm lost now since I'm a noob and i told him im EFI.

I'm lost now. What's this talk of austempered steel, and why is he makin me swap dizzy gears, I thought C O M P cams are all billet cores?

Help me out here before i drop the $$ on this bumpstick. Something doesnt sound right.

Distributor Gear Materials:

1. Cast Iron

2. Composite (offers great life, conforms well to the mating cam gear, and is compatible with ANY camshaft gear material)

3. Melonized or hardened steel (material that OEMs use with factory roller cams; many aftermarket distributor manufacturers use these as the default gears for their distributors)

4. Bronze (conforms well to the mating camshaft gear and will not damage the camshaft gear, but it is a self sacrificing gear intended to be used in race applications only and should be replaced about once a year)
If you have a cast iron hydraulic or solid flat tappet cam, your distributor gear options are:

1. Cast iron distributor gear

2. Composite distributor gear
If you have an austempered ductile iron hydraulic or solid roller cam, your two options are:

1. Melonized or hardened steel distributor gear

2. Composite distributor gear
If you have a billet steel hydraulic or solid roller cam, your two options are:

1. Bronze distributor gear

2. Composite distributor gear
COMP Cams® recommends the composite gear because it is compatible with all camshaft gears – flat tappet, austempered cast iron cores, and billet cores. If the steel gear is not hardened, it is not compatible with either of the roller cam types.

Note: If you have an austempered core hydraulic roller cam and a .500” shaft distributor with a steel gear, verify with the manufacturer of the distributor that the steel gear they use is a melonized or hardened steel material and it will work fine

sadi cores are what they most use unless you specify billet..........standard roller cams accept your stock dizzy gear

Be careful of the composite dizzy gears.
They are intended to be used in dry sump engines only.
They will NOT last if the regular oil pump is used, they are not made to be taking that sort of load....

35-351-8 is my cam choice. The composite gear is 120 shipped...expensive!

Is this cam choice a "standard roller" because I'll ship this austempered steel core cam back and get a billet core version...that would be 40 bucks as opposed to 120.

Reason why I ask is in my head, im thinking the stock cam is indeed a billet core camshaft.

So if I put a billet core comp cam in, everything else should be the same except for the cam specs, and I wont need to swap out the expensive dizzy gear is what I'm trying to achieve.

Thanks in advance for the help/advice

that's a standard sadi core, stock dizzy/steel gear is all you need for it
