On a side note, would you guys ever buy a used cam and lifters? i have found a mopar purple 484 cam, with lifters. I can probably get it all for about 100 dollars. Only ran for 1 hour on a engine stand.

Is this risky or stupid to do? or not? is 100 for a cam and lifters a good deal? Im just curious is all....if this is something to pursue or if im better off buying new

Yes,
I have used that Edelbrock kit in the past.
However,
there seems to be a problem with information exchange on this forum ?
so,
You may wish to read this Tech article from Hughes Engines regarding Aluminum Head useage in it's ENTIRETY, especially the last half of the article.


http://www.hughesengines.com/TechArticles/7choosingheadsaluminumvsironwhichonesdoyouneed.php

a quote from the article:

Aluminum heads dissipate (get rid of) heat much faster than iron heads. The rapid heat loss from the combustion chamber results in reduced combustion chamber pressures (heat equals pressure); similar to the effect that lowering the compression ratio which lowers cylinder pressure. When switching to aluminum heads you MUST raise the compression ratio to prevent a power loss. This is a good opportunity for our customers to take advantage of our computer calculated compression ratio service. This software assures them of getting the maximum power out of their purchase; it's a no-charge service for our customers.

Aluminum heads will not automatically create more power than iron heads unless they flow more air and are installed on a higher compression ratio engine. In cases where you have a decent port job on a set of iron heads it is possible to bolt on a set of out-of-the box aluminum heads and lose power. Aluminum is automatically lighter but not faster.

whats your build

The reason i ask is im thinking about doing a new cam, and heads down the road....maybe it would make sense to do this instead?

I am using basically that combo, although I didn't purchase it as a kit. Same heads and intake with a comp xe275hl Johnson lifters and billet timing set on a 10.2:1 448 short block. It has pushed my 4000lbs plus charger to a best of 12.83 @ 109.8 so far. I imagine their cam would give similar results but with probably less vacuum and a rougher idle. Component quality is good.

As stated above - angle plugs can be an issue with some headers.
