Hey that's my Bob cam! Now the million dollar question is if I should fire it up and run it? Or pull it? I think I know the answer to this one. The thing that frustrates me the most is... last year when I started my project build several people referred me to him. I've built several engines over the years and never once did I run in to so many issues.

The RPM expected to run with those cams is 5800. I stressed many times on the phone with MK reliability was most important to me. Like most I don't have an open check book. The exhaust I am going to run is Gil dry.

Dude you actually cracked me up. And here all this time we thought "what a big brain on Bob" and here he was just throwing darts and counting his money laughing at us. Wtf gentlemen.

I stressed reliability also... And it's been a nightmare...

Honestly,,,, just take a look at tims and others. I wouldn't take a chance over 800.00 worth of cams. Next thing you'll be getting your cranks ground and new bearings and who knows what all else.

Where RMBuilder been??? You would think he would defend himself?

Busy having a moving sale...

I only have a single. The thing that sucks is I just put it in the boat and almost have it ready to fire. It's been a big project. I did a complete bilge makeover, the engine, full hydraulic steering, K planes, and a new drive. I really wanted to get it up and running and play around with this new Holley HP EFI system. Oh well, I guess it's it's just another speed bump in the never ending project lol!

Pg 97. Near a Q&A record ?

The bigger surprise is everyone's getting along this time lol

My build thread may be longer not sure... I make heated threads but man the leading is intense haha

We can all relate to the endless hours that seem to never end. Been there, still there and will probably always be until I'm ten toes up. Maybe at some point we'll be comparing notes on how to make our own personal antigravity crafts how to bug out into other dimensions. Ha. For now puff puff..

Back to your dilemma I would call bob and ask him wtf has been going on with his cam lobes and you have very reasonable and great concern running your engine. Bob will undoubtedly tell how Tim probably had his rocker arms tightened til they couldn't turn no more or something to ease your mind however but we all know that isn't true. Plus this now goes way beyond just tims. MT made note how many have just been dynod and not even run much if at all. Heck I even know of probably a half dozen myself. Pull engine and swap out cam with one of the several shelf cams mentioned in this thread. I'd bet 651 cam wouldn't be much less power and look at the piece of mind you'd have. I wouldn't wanna be changing oil every trip out and cutting your filters open with hopes of not seeing bearing batter. Why chance it. Just my advice. Try and get your money back also. What's he gonna do if you start wiping out lobes or worse yet perhaps destroy an engine besides say it something you must have done wrong. BS. Do yourself a big favor while you have the opportunity.

Was thinking same earlier. I'd say yes.

How many of you actually checked your new cam dimensionally?
Or
Are you going by the specs it should be machined to ?

If anyone wishes to do so. PM the following on your build.

Cam specs. Duration at 050, lift at valve , LSA , and ICL
Cubic inch -Bore-stroke
cyl head make and model ( AFR/DART etc, with runner size, etc)
Static compression
intake manifold make/model
carburetor make/model
Exhaust system setup
HP promised
MAX RPM desired
Dyno results if any Peak HP and Peak Torque RPM

I will build a list , of builds, and post them in a separate thread . This way, you can anonymously look, and compare your custom cam, to others cams in similar builds. Your name will not be attached to the build specs.

It would be interesting to put one of (if not both) of your cams in a cam doctor Tim.
Billy's old man's friend that does the flow work also has a cam doctor.
Pretty sure he only charged me 25 bucks to do the supercat cam. (Needed it done so I could sell it on eBay)

edit in..... It would also give you all the info as apposed to just duration @.050 and lobe lift

I won't fault someone for starting such a business, and in business mistakes happen, but if the high rate of failure is true, not providing anything special as advertised, and is toxic to fellow business owners than good riddance.

New job.

I've got 2 sets of "marine ready" heads at the machine shop now being gone through so that they are actually ok for a pro charged marine motor. Was promised time and time again they were ok. They were not. I'll probably use the cams as door stops or hood props.

I am very sure Bob hates me and rightfully so, I exposed him and don't regret it, anyone that thinks its my building myself is at fault is dumb, building errors show right away as we saw, parts errors show after yo make it past building error timeframe...

DO I need to? I think you have everything you can need from me LOL

if not let me know...

The conversation between myself and The owner of AFR was interesting.... they do NOTHING but toss in whatever valve and spring Bob says, no "special marine spec machining" as told...

Is the hard annodizing an option?

I am sure glad I put crane 651 cams in my engines this summer and did not go with a special custom grind cam. :sport009:

wise decision.

Yes be glad you did. Thread helped expose many good off the shelf cams that had pretty well proven results. Btw what build did you use the 651's in?

Its funny. I have Comp, Lunati, Howards, Crane, Erson, Crower, catalogs here. Literally hundreds of cams for hyd roller bbc chevy engines, fitting everything from a towing 454, to a drag strip 598.

Then the need for a "custom cam" comes up. Problem is, all these cams that come from MK, appear to be almost a once size fits all! A 548ci gets fairly close to the same cam, as a 496/502! Almost all the same LSA, almost all the same ICL, durations within a few degrees, lift within a certain range, etc.

A AFR headed 9.8:1 540, gets almost the same cam as a 9:1 GM iron headed 540, with a full point of compression difference too! How many guys had to be schooled on the importance of static compression, and its effects over the phone. The recommendation of using the thinnest head gasket possible to maximize the combo. lol

Tried pm u. Box is full.

back when I used to talk to bob, I was in the process of helping Icdedppl put his 540's back together. Was a basic combo, 540, dart 345 heads, 1071 blowers, 651 crane cams. He told me we were leaving 100HP on the table with those old antiquated cams on dans build. Sure glad we decided to leave them in there.

Whew, Good thing you did , me and Joe had no idea for the past 2 years

:rolleyes:

540ci
dart 345s
8.2-1 compression
tbs 8-71s 6% under driven quick fuel 850 carbs
emi thunder manifolds with dry tails

Bob should go into selling Kirby vacuum cleaners. I am really disappointed and feel bad for the many who have fallen into the Bob trap. Has bob addressed any of these known issues? Can't wait to see thread MT is going to start. I think it's wise also MT is keeping names out of it for many reasons unless they don't care. I think the list will grow. Some not only got screwed but also got their pride fked with bad.

That`s pretty much my combo, 651 works just fine.

it all started to unfold when I was having my issues, early in my build process you, Joe and I were still Pro Bob.... right after I got all my parts is when things started to get off... I remember asking opinion on Scorpions you had at the time, was happy still lol

thats what my gf says.:),,i'll empty it again.

100 pages. Good Lord.

Shouldn't it be the other way around. I hope.:ban:

I was told over and over- compression, compression, compression! "you can't use that cam unless the compression is a point higher" WTF!

You don't miss much do ya. Lol... But I bet you didn't know 2017 shameless started tonight. Normally not til January. Why now after 7 years? Frank gonna be president or something.

Just imagine all the unhappy customers who are scared to post, don't like drama, or are not even member here!

Had I been ready a couple of years ago, I probably would have been one of the unfortunate souls to have gotten taken as he seemed to be the man at the time. I have to guess there are a ton of bad builds out there that either haven't reared their ugly heads or just don't have enough hours yet to show the issues to an extent the owner realizes theres a problem. :cartman:


its fall, isn't everyone supposed to be fighting? :daz:
