Howards Cams

Does anyone know what is going on with Howards Cams? I'm been trying to contact Ben Herheim, to order a cam, for almost a month. I've ordered several from him and he has ALWAYS answered the phone, on my first call. I have called about 5 times, in the last 3 weeks, or so and left, at least 3 messages...

Re: I Still Like Pushrods, They're Still Viable

We must now add one other American owned constructor, McLaren. As a matter of fact, the rights to F1, is also, now American owned.

But, it is sad that there have been so few American drivers. You did forget, at least two American F1 drivers, Eddie Cheever and Alexander Rossi.

The answer is, Dan Gurney. His car, Eagle His engine, Gurney/Westlake He drove his car, too Although not a American, Jack Brabham was the only other, to do so. But, that is really irrelevant. Penske just didn't knock on enough doors, I guess. Just like his US competitors didn't. He was last competi...

Re: I Still Like Pushrods, They're Still Viable

"half-in"? Seriously, when did Penske ever do anything "half-in"? Are you saying he purposely got into F1 w/o being wholeheartedly committed? He got out, only because he couldn't compete at the F1 level. Today, he can't totally dominate, even though he always tries to buy the best drivers, because I...

Re: I Still Like Pushrods, They're Still Viable

Perhaps the fact that Penske's sponsors were mostly US companies who had little interest in European racing, did not help matters any. Penske once remarked, "They knock on the same sponsorship doors that we do." F1 is a world wide market. USA sponsors wouldn't matter(although one of his sponsors wa...

David, if that is all true, can you then explain why Penske wasn't successful in F1?

Re: I Still Like Pushrods, They're Still Viable

I've never been a fan of Penske, not because he pushed the limits of the rules but, because he was always able to out spend the competition or have a "in" with a car company. I've never had any respect for people that buy their success. Not until he started his F1 team, did he compete on equal footi...

Re: I Still Like Pushrods, They're Still Viable

Didn't Penske, Chevy, Ilmor once build an Indy race engine using pushrods? Sort of? Kinda. Correct me, if I'm wrong but, as I remember it was a Porsche designed and built engine and I don't believe it made the race and also never returned. Again, as I remember Porsche built or was heavily involved ...

The valve train mechanics will allow higher engine rpm without valve float problems,
in order are:
OHC gear drive
OHC belt drive
CIB push rod.
Doesn't the gear drive create harmonics and friction, that the belt drive would mitigate, at least to the limitation that valve springs have?

Re: I Still Like Pushrods, They're Still Viable

Ron, this is a drawing of the Ford, Duratech 3.0, V6. It has a deck height of 8.189. I would be surprised if it was wider than a LS but, I couldn't find a measurement. I've inscribed the 2 red lines, point out what it might look like if it was a SOHC engine. Based on the bore and stroke, the DH coul...

Re: I Still Like Pushrods, They're Still Viable

I suppose a point could be made in packaging a push rod, over a DOHC but, not a SOHC. We'll have to agree to disagree on this statement. Put a Ford Mod SOHC 4.6 (25" wide, 26" tall) beside a 5.0 pushrod (18" wide, 20" tall}. The SOHC is a huge exterior package for it's displacement and power output...

Re: I Still Like Pushrods, They're Still Viable

Sure the push rod engine, is still viable but, so is the Ford (and others) flathead engine. The push rod engine can produce more torque and HP than the FH but, the 4V will produce more than the push rod. I suppose a point could be made in packaging a push rod, over a DOHC but, not a SOHC. If absolut...

Re: Push Rod Oiling

The way I have looked at it, is that since the ball and socket, aren't pressure lubed, that just splash lubing would be all you need. If spring cooling is one of the goals, I think push rod oiling shouldn't be used, at all and external spring oiling needs to be used, it's much more efficient at cool...
