building a 360, and newbie 360 questions!

by "screaming" engine, you mean a high RPM engine, running something more sturdy than the stock bottom end? or is this good for a build WITH the stock bottom end?
Not to it's fullest extent, but a stock bottom end is fine for 6500 rpm blasts. I wouldn't hold it at 6500for long. The Holley is rated at 3000 - 7500 I thikn. It's been awhile since I have seen an advertisement for it. There not made anymore a far as I know.
the Eddie heads aren't that expensive- would these heads flow similar to the aluminum eddies,
All edelbrock heads are aluminum and they do not flow enuff for the builds in the link as per what he did. Stock Edelbrock heads are good to about 480 HP and then you'll need to touch them up or port them for more power.

i have also heard that i can up my compression with pump gas by a full point with aluminum, which would make for a SAFER 11:1 compression engine. my friend built a 318 running 11:1 on pump gas, and it ran very nicely with the aluminum heads.
Yes, it is because the heat lose rate is high and a 11-1 aluminum head is alot like a 10-1 iron head.

which is the last package we're talking about here? package six that i mentioned?
Package 9 on the 360 web page. It's kind of a over the top build for a street car. And a bit to handle properly for a street strip car. Your tiny tires must go. The 275 tires would have to be a drag radial like Mikey Thompsons or equal.

i guess i'm sortof mixing and matching here, making my own "package." i don't like the idea of having something just like everyone else's.
If anybody copied his builds, I haven't heard of it yet and to be honest, theres no shame in it. If you are not sure about what your doing, I'd recomend that you copy a build rather than screw up one of your own and end up paying twice on an engine.

thanks demon, it sounds to me like the edelbrock heads are the way to go.
IMO, there not. I own a set and there good for what they are, but after there purchase and there limited porting abilty's, the iron head would be better and you have it now.

Couple the fully ported iron heads with the 2.02/2.60 valves on top of a KB 107 piston and a Fel-Pro gasket @ .039 thick for a great quench area and pump gas useage. It has the abilty like this. I ran this combo before.

Use a cam of your choice in the RPM range you want to run in and top with that Holley intake and carb. The only other thing I would add is a set of bigger than normal tube headers. The 1-5/8 tube size is a one size fits all type of header and has ground clearance issues. The more expensive Doug's headers or the much more expensive TTI headers would be the best parts to use in this build. OH, 3 inch exhaust pipes!
