cam change what to expect

zbob wrote:yes randy reality set in. what I came to appreciate is this is still a fully streetable, power brake equipped, muffled, idling, decent engine temped car I can use and drive ......bob

super, yes still have the 327 gears. gear changes and a plate kit is a winter time goal. its fall in northern Minnesota. time for outside get ready for winter chores. fwiw should have got a small cell a long time a go.....bob

You got an increase of about what I expected for your combination.
Keeping it "fun to drive" is a lot of what this is all about; unless it is an all out race car.

If the board want to see it and your willing I will design a custom camshaft based the engine combo and the goals. Here is my only stipulation. You pay for the cam when I send it. Once you test it no matter the results I refund you the money for the camshaft. Offer is on the table.

Won't happen on the dyno stuff.  Most dyno shops have water brake units.  A water brake dyno below 3500 rpm is not accurate due to the absorber and how it works.  Now Ford has a few that will test them but most engine shops don't drop a few million on just a dyno.

Just about ANY electric dyno like a GE, Westinghouse or Froude will pull a 1,000 lb/ft diesel down easily.

Katech has 3 of 'em and they are within walking distance for me.

That would be fun to do some tests with. I would like to see some of the old single pattern cams run against all this new stuff just to see how they compare. Not a lot of dyno charts on the 460's at least compared to the SBC's. I am not trying to put anyone's cams down, I just would like to compare them with a basic stock engine and heads, with headers, dual plane intake and 750/850 carb. Most of the dyno stuff is more race oriented it seems. ZBobs test is very not subjective as it has too many variables, still waiting on 60ft and 3.30 times with the old one to compare. Also his observations of how he likes the cam change on the street as for as overall performance, compared to the old cam would be nice to.

pm sent. straub....thanks bob

Well Bob, Straub has laid down a challenge.
I know what you've done with a pile of bolts and happy that it's always improving.
We know each other's rides like their our own and I wouldn't pass up Straubs offer if it was me.
I want to see the Zephyr in the 11's!!!!!!!!!!!!!

We have started the ball. Bob is going to call and we get the details worked out.

So no other changes except a cam swap?

I would like an offer like that...............

Over the years I have not sold cams to customers who have called to change cams. If the stick in the car is fairly close to what is optimum and we can get there with a lash adjustment and maybe some cam phasing then I give the guy that info. I won't sell someone something they don't need. Now if the cam is going to make a difference I will give you a % of increase and the customer can decide if the increase is worth the money spent.

Do you have any idea yet what the percentage increase will be that Bob will pickup over the Lunati he has now with a custom grind, and are we talking peak HP or E/T's?

yes I do, but in the era of "Internet Lore" I would rather stay quiet and let Bob's results do the talking.

and bob is wise enough not to share intelctual information. bob

OK LoL

This should be fun. Good thread.

yes he got torn down quite a bit when it first went out on the OH pulling circuit. I will post the results of this Thor headed 610CID in a few weeks. It is 17 to 1 on Alky.
