Quality Budget 408

While I will often recommend Edelbrock heads it is because of the ceiling the offer in performance. OOTB and ported.

I have no issue with OE or W2 iron heads. I have often said in the past that spending money on your parts your way is the only way you should part with your money and iron heads are fine IF you don't mind not loosing the weight and there limited performance ceiling.

OE iron heads are approximately 190-200 cfm's on the best castings. Some may flow a bit more. Ported, they can go 260cfm-ish. W2's are 260 OOTB and can go well over 300cfm.

In terms of potential performance, there isn't a whole lot these cant do in the street or for your street strip ride. The biggest problems are getting someone to do the work and hearing the crap about the bennifit's of aluminum like your a dumb ****** that's been living under a rock your whole life.
