edelbrock performance package

The "Performer package" is best compared to a dead stock engine with a cam you'll never no that was there.
The "RPM Package" is nice with the only complaint of the cam being not what it could or should be. OOTB head quality can vary and is often subject to forum suggestions of "You better have them Checked out first."

The cam has a wide centerline and lazy-ish lobes that make for a softer idle than that muscle car sound most want. Lift is way shy of the heads high lift flow abilities. This all leaves a lot on the table. In general, it does perform, but a little thought on a different cam can yield great results over the Edelbrock cam.

Also, on the heads, it has always been a point of being a catch 22 with ported iron and the cost and extra cost of checking the head out in performance terms. The iron head will only flow so much ported. In a apple to Apple state of the heads, as cast, preped, ported, fully ported with bigger valves, the Edel. Head always has the performance edge, but not so much in price vs. the head you all ready have.

This is my opinion of what I felt like the change was going from 2.02 J heads to OOTB Edelbrock heads. They ran like a well preped bowl ported "J" head. It was a nice improvement.

When you use the iron head and invest money into it, it will out flow and should out perform the Edelhead at the stage behind it. An example would be a re worked bowl ported 2.02 iron head should out perform the Edel. Head as cast. A fully ported iron head should out perform a bowl ported Edel. head. But that's where it ends since the Edel. head can be ported out beyond an iron head.

Now is the time to decide if the iron head will meet flow/HP goals.
If it will, the. Save the purchase cost of the Edel. head (At what now? $1500+ Machinist check out) and roll that money into the iron heads.

A lot of people will wave the weight flag as a bonus and it is. But I want every reader to think first. Is the 50lbs. Weight difference really going to help you in the street? At the track? In which most races are won and lost at the line.
How many are racing for money in the street and need that 50lbs.?

Hey! It's your call, your money, have at it.
