408 W2 combo - where to from here
dont waste money porting iron heads...
you can buy alloy heads that already have better flow for about the same amount of money you would spend on porting.
This statement is largely incorrect because the W2 head will port out and flow really well. The heads are capable of pushing a lightened car into the high 9's.
These are the only iron head worth porting for big power.
The W5 would be the first step above this head. Or the "Air Wolf" head. Not the Edelbrock.
The W2 will flow 20cfm over a Edelbrock head easy. Also, once you pay for the Edelbrock head, then port it, equipe it with the upgraded valve train, you'll have spent more on the head than simply porting out the W2!
You have a superior head now, just go forward with it.
The head once ported likes a high lift cam since this is where it will breath the best. Take advantage of this with a new cam, custom cut if need be. It really doesn't cost anymore than a off the shelf grind.
More converter is an excellent suggestion. Work your suspension next for a shorter 60' time. I like the bigger carb idea as well. Your cars weight is the next biggest issue. If it were possible to get it down to 3,000 lbs. , this would be the a soulute max weight I would want.
I know cutting 200+ lbs. can be a lot from a street car.
