Thumbing through the jegs catalog the other day and I discover that they are now offering a house brand cam. They look cheap enough, but why is everything ground with 114* lobe separation?

I didn't see the full specs, just duration and lift listed. ?

Most likely the same old PAW, JC Whitney, Summit, ETC cams from the early 70's

Ahh. didn't notice the "more info" link.

Odd. Maybe to increase cylinder pressure on low compression motors.. I dunno.

I had a local shop build an engine using that first one in my engine with the 510, 533 lift. Have not fired her up yet. Hoping to have it running in the next 2-3 weeks. I'm still confused about the lobe seperation and how it effects torq, top end, and Vac. Can someone tell me what to expect with this cam?

This is what I have. 388ci. flat top pistons, RHS Alum 64cc heads, TH350 w/3400 stall and soon to have 4.10 rear.

My sons and I are using this car to take to the strip and weekend cruises around town.

This is my first build and tinkering with cars in over 20 years, so it seems like I am relearning everything as I go.

Thanks

I wasn"t trying to save a few bucks..... Do they use poor or cheap materials to make the cam?????? What exactly makes them JUNK? Old type of grind? That doesn"t make them junk.

Could you answer any of my specific questions about lobe?

Im sure he meant junk as in they are old designs with old school lobe patterns.

That 114 means the RPM range is going to be later in the band....meaning your going to have to turn it more RPM to "get it to run" so to say. That also gets them to not have much overlap so its not going to sound too radical either.

They are probably alright for what your doing, but definately not good enough to be drag raced heavily.

What is the compression ratio (static) ?

I do not know. What info do you need from me?

might want to watch out for some of those old school cams

i used the Crane Blazer which is old school and it hurt many NEWER cams

234/244 @.050" .488"/.510" 114 , Those old cams need more compression than you would think by the @.050" numbers because of the LONG seat duration

With the Crane Blazer above, which we used many times in 327's, no less than 10.6:1, ran as high is 11.7:1

What "junk" have you used and sent back from jegs? Ive got a lot of jegs "junk" on and in my car, and it has all been good quality stuff that has given me zero problems.

They are old school grinds, with a wide LSA for better idle quality (less overlap) and a wider powerband. They also have gentle lobes with less lift so they are quiet, easy on the valvetrain, and last a long time.

For a daily driver style car, I think they work just fine. With the cam issues coming up with todays low zinc oils, I think these might be a better choice for a daily driver style car than a high rate of lift cam like a Lunati Voodoo, or a Comp Cams XE series if you are going flat tappet. They might not make as much power, but I can live with 10-15 less hp if it makes it through cam breakin much easier!

i assure you they arent junk, i run the siloam springs show-n-go, we were out of our "white box cams" and couldnt get anymore for a while, we dug deeper into it and the cams were comming from "crane cams" and stuck into a white box, and when crane went out of buisness we couldnt get them anymore, just like "big end performance" converters are TSI , big end jets and carb parts are holley ect... these big name companies arent making money anymore because people automatically assume that since they are a name brand they are to high, at least thats the case in this part of the country

i've sold quite a few of those 510/533 cams and everyone i have sold them to are very impressed with the performance and sound.. no problems here. and thats comming from someone who sells them and deals with these customers on a daily basis, the store has been around long enough to know whats junk and whats not :bowtie:

No name engine components always make me nervous... they have zero obligation to put any manufacturer's cam into that box.

For $120 you can buy a name-brand cam, just make your life easy and drop a couple of extra bucks

Juice cams?

114 LSA = less overlap = more idle vacuum for power brakes etc. Just a thought.
