New G3 Hemi Block...

I have a decent small block, but for what it cost I could've done a Gen lll and had money in my pocket left over. It's my understanding that 330 isn't to hard out of the Apache head and more if the porter knows what their doing. As already mentioned it's not all about flow, but the Gen lll heads are efficient. Just look at the timing these engines are running, it's not much. Also the blocks are strong, and easy to find, plenty of them living in pretty high HP applications. How many R or X blocks do you see floating around? Yes they pop up from time to time, but the last one I saw was $3K. If I didn't already have a R1 I probably would've bought it.

Yes the W-7,8 and 9 heads are capable of great power. But how hard are they to find? Then the cost for valve gear and porting. A lot of guys are running factory rockers on their performance Gen lll engines. I need to talk to Brett and see what a set of his heads go for now. He is also working on some Gen lll stuff from what I was told, it'll be interesting to see what he can do with them.

If you're talking about a max effort race engine the cost would probably similar. But I believe if you're looking for 600-750 reliable HP the Gen lll is the way to go.
