new 434 combo HP predictions

[Keith Morganstein]

Big Joe no disrespect but this is where these posts turn to shit.
HP predictions for my new 434 combo. Not how big my dick is.
Not everyone uses tunnel rams,Two carbs,massive valve springs
Ridiculously large cams to make 680-700 hp. I would imagine most
Of us are bracket racers who race on a budget and like minimal
maintenance. You seem to pop up all the time but offer no real informative
advice just telling us how good your engines are. What size cam would you use for
680-700hp??
And please little cam. Pffft

Big Joe gives lots of helpful information. However, you must be smart enough to understand it

Fair call I was probably a bit hasty in that comment,But I still dont see the point in his comment in this post, no matter how smart you may be.

Here is some info Joe gave that was not even close LOL

The bigger the cam ( lobe design ) the more room you have. Your cam is pretty small, that is why you have an issue. Usually 1 and 2 and 5 and 6 are the close ones, so look it over very closely.

Joe you are not making any sence!!!1 Its always the nose area of the cam that hits the rod not the base circle of the cam.

If you have a .300 lobe or a .450 lobe the lifter will be the same height in the lifter bore, But the .450 lobe has a smaller base cirle which it has too. The more cam lift the smaller the base circle. If you need more clearance you go to a smaller B/C which will make the lobe shorter

Im hitting on rods 1 and 6 and the cam is clocked in dead on the cam card specs.

Is the cam actually degreed in ???

Something seems wrong here as I have used a .420 lobe with 3.875 stroke 2.100 jounal with a 1.000 B/C cam and have had .048 clearance

It has been so long since I have had that same problem, I must have been thinking about a flat tappet cam, where the smaller and milder cams have much bigger lobes, compared to the more race type, where the lobe gets smaller in order to make it have more lift and duration. I knew I was stepping on my dick as soon as Carl jumpped all over me about. Sorry about that == I am getting pretty old, and I am forgetfull now and then--- MY BAD

Nobody is perfect and some people just love to criticize. I've been doing this stuff for a long time now, but read all of your posts and still learn a few things along the way. This forum is at it's best when ideas are shared (and everyone benefits).

Thanks Keith, I aqppreciate that

I think a book by Joe would be a great read......... how much more experience could one ask for ?

[bigjoe1]

Funny you should mention that. I have been approched twice now about that very same idea now.. I am going to look into it. As i get older, I feel much less like I want to keep working, even though it is still fun ( usually ) I am down to where I only go to my shop about three or four hours a day, unless I am very busy. I know sometimes when I get a call, we get way off track talking about something that happened many years ago, but that is OK with me.

Just curious Joe, do you have a bunch of guys working for you, or is it just you? Or a few guys?

[bigjoe1]

It is just me, and I do have a guy I use part time, if I get in a bind. I am the one to blame for everything that happens.

I know that feeling

So Joe when is your book comming? and shit I never built anything over 600hp won't offend me telling me how big your cam is , just some of us take shit the wrong way.
One time for my mild rv like voodoo crammed motor wanted more , i wanted to try a bigger rocker ratio. I called Summit, the guy was telling me like I didn't know my ass for a hole in the ground, that it was going to make my cam soooo f'n huge bla bla bla "are you sure you want?"' I said " no, I want my Dick smaller" then hung up Called back and ordered my rockers from a different person. Now that was an asshole!

My favorite Joe Sherman quote is: "Everybody needs 20 degrees more duration than they think they do." The #1 way to make horsepower is to raise RPM. The way to raise RPM is with more duration. This is about as basic as modifying for HP gets. In a normally aspirated engine, HP is going to come from RPM. All one needs to do is look at Pro Stock and NASCAR. 9000+ RPM is what's happening. The talent lies in making it happen for longer than 5 seconds.

Your local speed shop/engine shop more than likely would have given you the right answer and better service. Buy local, help the little guy.
