427 SBF

An interesting thought: Maybe the person who speced the cam is keeping the torque hit down to keep you from ending up in a ditch.

The small cam 502 in my '66 Vette overwhelmed the tires with any kind of throttle.
It made me giggle but it was kind of useless and I had to be pretty careful.

These new cars with big horsepower have traction control...

You aren't the first person to bring this up and that's definitely possible

Radials and a stick is going to be worthless in my turd. I have the Hoosier dr2 because when I was ordering the mickeys were out of stock with no backorder

Mines a manual. MT street R's are like slicks on the street. I could be rolling as slow as possible in 1st gear and smash it wot and they didn't even try to spin, and thats with 20 lbs of air and no heat up.

Goodyear was purchasing MT, think that didn't happen or was sold again

That is more duration than the engine in my race car.

Sorry 🤷‍♂️?

But it was only 636 lift and 108 lsa if that helps 😉

New one from jones is 278/284 with 837 lift but wider lsa, plus some fuckery 😃. Should idle just as good and still a 4 speed, just jerico instead of toploader.

Do you know who you're talking to? I had to disassemble my dremel yesterday because the bit was locked in there. The pin to stop the chuck from spinning was stripped

Booooooooooo.......... No more excuses, get this turd, I mean Furd, together!

Why no camshaft end play? What limits the rearward movement? Timing gear? I don't know Fords..........
 
The distance between the retainer and the cam gear creates the gap to allow oil barrier.

So the hub of the sprocket bottoms out to the face of the cam. The face of the gear should not bottom out on the retainer, but mine does

So, with the cam in the block and the retainer in place, do you have end play? The plate will stop it from moving forward, but what limits the cam from moving backward at that point?

I can see the cam gear limiting rearward movement if it can make contact with the retaining plate. I would assume that is where a torrington bearing would be, but on a stock engine they may just rely on a film of oil.

And I know the chain should NEVER contact the block. That would be a bad day.

Part of running 12.8:1 on pump.
Probably would've made more power with less cam and compression, lol.

Why run so much compression? I know E85 could help with that, but it isn't always easy to find. What engine is this?

Nothing stops my cam from falling rearward out of the cam journals if you push it rearward without everything bolted up.

The cam gear hitting the retaining plate is what stops rearward movement on mine, so it has to be bolted up and torqued. It's a single bolt in the center of the cam/ gear. The new timing set has a Torrington built into the inside of the retainer, and the cam gear has another Torrington that rides on the outside of the retainer

To make as much power as I could without porting etc.
E85 is the equivalent of going electric to me, 😉.
It's a 351c🤮 with a 4" stroke, 409c, made 600hp
 
Ok, that makes perfect sense. So, when you put the cam gear on it that is when you lose the end play? How do you fix that, take material off the cam retainer plate? Or machine the groove for the torrington bearing on the backside of the cam gear deeper?

Does it give end play specs ?
