Looks like I'm making a call tomorrow, I appreciate the Info.

 

Let us know what they have to say and your thoughts!

 

Alrighty had a good long conversation with isky cams concerning a custom grind... Heres the specs for the custom grind they provided...
257 advertised duration
210 at .50
.480 lift
108 LSA


They also mentioned an off the shelf cam...




this one is more economical than the custom grind, does anyone forsee any problems with this off the shelf cam?

also what does standard gear drive from factory mean?

 

That is a nice cam especially for todays gasoline..... should even give you IMHO a 1-2 mpg increase during normal driving yet give that engine the ability to breathe deeper which will develop more torque. Standard gear drive means just that.... all oem type parts for the timing chain, etc. nothing special required......that doesn't mean you can't upgrade to a double roller chain to oem specs. The only difference I see is the custom grind will give you just a bit more power....if it's is $100 more than the off the shelf..... I would go for the custom because you will actually get a gain for the $100.... if $ is tight, then go for the off the shelf.

Sounds like you had a great conversation....it makes it so much easier just speaking with the "guy" whose going to be grinding your cam! and I'm sure he recommended the "kit" that they would provide with the cam to!

 

That off the shelf cam is terrible IMO, it will totally strangle this motor.
Do you still have the stock roller cam? For reference this is what it looks like.
256/266 adv duration
198/208 @ 0.050" lift(not confirmed but a good guess)
0.422/0448" lift with 1.6 rockers
116 LSA.

This cam works great with a carb and with 1.7 rockers it's about as good as it gets for torque output, powerband is 0-4500rpm

 

Oh yeah, it was really nice to talk to someone who could make me a cam for my setup, not for a general engine family. Money is a little tight in this part bring that it is an engine swap, might have to go with off the shelf cam. I plan to continue research until I can feel really confident about my decision.

 

I second Conanski's choice of cam. Presumably it's free as well.
I'm referring to the stock 351 roller camshaft.

 

update... the mile a mor cam is for the inline 6, i didnt even check vehicle fitment, that is why the specs dont even meet the stock cams performance.

this looks like a better off the shelf cam...

110 Lsa still should have some lope to the idle right?

 

Looking at the discussions, before we start saying things like "It will choke the engine off", etc., let's remember just a couple of things 1) the peak power band on this stock engine is around 4,500, so will it choke the engine off- no, 2) None of us were a party to the specific discussion he had with the Isky staffer including specific details such as specific driving conditions, elevation, fuel, loads, operating conditions, etc...… nor do we know the ramp profiles (no cam grinder is going to release this proprietary information)….. Heck, there is a "real world story" of one of the famous drag racing teams from the late 50's with Ed Isky himself...… they insisted on a heavier cam profile (lift, duration, etc.) where Ed insisted by reducing the cam the car would go faster...… they tried it their way and went slower......eventually they departed ways with Ed...… a couple of years later another team bought the car....went to Ed and he ground the cam he thought should go in there..... the car never ran at that speed/ET before (IIRR it was 5mph+ faster and they knocked almost 1/3 sec off the ET in the quarter mile).

Do I think he should speak with the other cam grinders, yes, to get their independent opinions/suggestions as well...…. now he can make a real informed decision of who to go with.

 

wouldnt be a bad idea to call around, might call Crower & Chet Herbert & Lunati as beechkid mentioned early in this thread for a custom grind.

 

Not a lot since the cam doesn't have a lot of overall duration. Why don't you just use the stock cam?

 

Keep in mind that even if the aftermarket camshaft maker thinks the stock camshaft is excellent, he's not going to admit that. Quite understandable, he is in the business of selling camshafts.

 

Wanting to make a little more noise and some torque. Yah can't beat the sound of a choppin cam. I can agree, the stock cam specs are good for the roller blocks.

 

Hijacking the thread as I've not seen much activity on it.

I'm looking for similar advice on a 331 stroker. I have a set of AFR 165 heads, T-Moss ported GT40 lower intake with the choice between a GT40 tubular upper or a somewhat cleaned up Explorer upper. This is to try to maintain emissions compliance. I will work with DSS to put the short block together with the proper pistons.

I'm thinking of using the TFS stage 1 cam, TFS-51403001 (.499/.510 w/1.6, 221/225 @.05, 112 LSA), and tuning my A9L EEC with the Moates QH to handle this. I have some Cobra 1.7 rockers, so can bump the valve lift by about 6%.

Would there be a better cam for a streetable engine that will not require too much tuning to achieve that and still make maximum use of the intake and heads?

 

That is why I always recommend the 'Cam Grinders" that I do...they are straight talkers..... and don't layout the PR material just to sell a cam.
