Any 10 second "All Throttle" 318's in door cars ?
This old book, I heard wonderful reviews by those that actually followed the instructions. In fact, the normal report is the package performs better than expected.
W2 heads are approximately $650 each, bare. They would be a little more pricey to set up then OOTB Edelbrock heads. The book does not mention any porting of the head at this stage. The flip side is an aluminum head and it would have to be at least mildly ported.
A better bang for the buck would be TF heads.
Now out the TT heads VW W2’s on the scales.
