Welcome to Idaho Spike! You're going to love it here. It is amazing how many people are fleeing the big West Coast cities and moving to Idaho. [Don't forget to update your forum Location/Region profile]Hey! I made it!
On top of all that, this coming weekend ( Labor Day Weekend ), of all things, the National Mustang Owners Association ( may have the name wrong, but it's a national club ) is holding it's annual show right here in Boise, and it's literally just blocks from my house, so guess where I'll be Saturday. Maybe I'll run into Machattack there, it's a big show though
Spike MorelliTony, I'll have to post the page from Icon's catalog, showing the special piston inverse dome that goes with the Aussie head chamber configuration. These heads have a smaller combustion chamber than the 4V Clevelands do, and therefore, will raise the compression ratio higher than what pump gas can handle, so a special piston is required. If memory serves, the compression ratio with the Icons is somewhere around 9.0 to 9.5:1. Chamber cc's , deck volume, and gasket volume , can be juggled, and will dictate the final C/R. The dish in the piston top resembles the chamber shape, so the quench area is retained. The cam I have penciled in to use is one of Crower's milder grinds, I believe they call it the "Torque Monster", or some such name. I'm still on the fence as to the final cam choice, I want to do some more investigating. All of my notes are at work, I am on the internet when I get home, so I'll have to make a note to bring home information.
The car will be used everyday, the car is an automatic and has A/C and power brakes. No "big lopey Hero camshaft" is even considered, rather a smooth idle. My spare block is a 2-bolt main, as is the engine currently in the car. Lifter bore bushing, and oil system mods are scheduled, and will be photographed and posted. Ignition will remain the Pertronix retrofit system, as it has performed flawlessly for so many years now. Induction is an Edelbrock prototype ( I posted photos elsewhere ) 4v intake for 2v heads , Holley 4160 most likely, although I like the Summit shoebox carb ( formerly sold and designed by Holley ), as it has all the features of a Holley and the Autolite 4100 4v carb combined.
As a side note here, I may take the heads into the flow bench room to get a baseline on what they have un-modified. This would give me a perameter for the camshaft, then, re-flow the Aussie heads after mods, if any, prior to assembly. At work, I am in charge of Assembly. Assembly is the "make-or-break" moment ( no pun intended ), and I will post detailed assembly technique along with cam degreeing, etc. I built a hot 406 Ford FE for my ski flatbottom, and posted it to a boat site, and many people told me how much they enjoyed it....so that is what I'm going to do again, here, but with the Mustang engine.
Thank You & Welcome back... been awaiting more details on your Aussie 302C heads...OK, It's been awhile since I last added an entry on this topic.
I told them that I had a pair of untouched Aussie 302 heads that they might flow for comparison, and brought the heads in the next day. They flowed my untouched heads, and found that my virgin castings outflowed his modified head. If I remember correctly, 220 CFM at .500 lift was my flow stock for the intake.
