Actually the F-6 is considered a dual single overhead cam design. Which was high tech back then and is the major reason it sounds sooo good at high RPM.
As for the 928 V-8 swap to a 911... I thought the 928 was made for the mouse replacement? And the P-V-8 becomes a pretty paperweight. BTW this also applies to older Jaguars.
Lets keep in mind that a very well built mouse that can take 7-8K RPM blasts is not cheap to build. The bottom end is not as strong/balanced as a F-6 and therefore will take much work to beef up. Jees a good crank, alum block, forged rods, light pistons, machine work, alum ported heads, and all the other goodies add up quick. Plus your cam selection to get the top end will kill bottom end and probably leed to a very rough idle. A mouse that would reach the same caliber extended high RPM driving would probably cost $10-15K if done from scratch. Yah, you can get 300-350HP pretty easy out of the stock V-8, but you still will not be safe at high RPM past 6K.
Personally, I love the F-6 song at high RPMs which I do not think the V-8 could match. NASCAR engines do not sound good to me.
Shoot with a stock F-6 bottom end and some head, cam, and valve work for ~$4000 I can see 7500-8000 RPM blasts. I will keep my mouse in my truck and below 4K RPM.
If it were not for those greedy dismantlers Porsche owners would not have to seek out cheaper ways to keep thier p-cars on the road!
