RE: Your right....also? By Paul G - 05/15/2002 3:28:56 PM; IP 65.105.39.2 Thanks Dave and Barry, The block will take a 14/64 in some places but will not go any higher. I am going to assume that it a decent candidate for sonic check, and not just a disposable 390. Also Dave, you mention RPM ranges in your post. I am curious, what is the max usable RPM I can expect to get from the C7AE heads. I have not posted very often, but I have been carefully reading the forum for some time. All the information I have read led me to believe that the small port heads would not flow well enough to get above 5500 with any HP gains. I would like to build the motor to maximze the capabilities of the existing components (heads & block) If there is a given max rpm the heads will flow to, Then I will select a cam based on that number. The heads have a slight cleanup on the exhaust side, but no significant porting. If the heads will support 6000-6500 rpm, then I'll work towards that. I plan to use the C6 rods with ARP fasteners and balance the rotating assembly. Aside from the block and heads, I have no limitations except that I would like it to be streetable. If being streetable means keeping it below 5500 then thats what I will shoot for. Thanks for all the great information!! Paul G. PS-Dave, the 427 blueprints are really cool. The framed copy will go nicely with the seven foot slide rule that hangs in my kitchen.

This thread, so far...
