[DeTomaso] 4V cc iron heads

[Ken Green]

Corey,
 
    Make sure the numbers you are comparing reflect torque over a broad RPM range.  Just making more higher peak HP at an RPM you see 0.1% of the time is not like increasing torque over a broad range.  Low and mid RPM torque makes a car a lot more fun to drive every day.

Mike, 

To answer your question:

I did do a total cost, and it appears that if I do the full Trick Flow setup with EFI intake that it's only a few hundred dollars more for my present situation.  It the heads had been in the shape I thought they were in, then it wouldn't be that close.

I am now leaning toward the aluminum.  I think the iron would make good power, but not for very much less in my case.  

Corey
