A friend has an "83 Mustang ragtop 5.0 w/4spd. He wants me to put a 5 spd in it. I have a T-5 from a 2.3 turbo with the big input shaft. Does anyone know of any reason this wouldn't be a bolt in swap?
All the best factory racing heads from Ford {and subcontractors like Weslake} had round or nearly round ports. Every pure bred racing engine I've ever seen or read about had round ports. Every cammer motor I've seen right up to present day whether Ford or Honda has round cylinder head ports. At the same time, most all of the street derived pushrod engines use rectangular ports. I've read Mcfarland's theories on "flow beads" and flat port floors, and I know it's easier to maximize port area for a given height and width by squaring it up, but I still question the practice.
Does anyone care to expound on why the factory exhaust manifolds on the 4.6 mod engines are wavy when viewed from the top? The internal volume doesn't appear to change from front to rear, but they have a distinct radius from port to port! Why?
Alex, can't remember ever seeing a distributor quite like the one in MoneyMaker. What is it? Also, do you use thermal barrier coatings in your cumbustion chambers and/or friction reducing coatings on piston skirts?
When cutting valve reliefs in pistons, how much larger than the diameter of the valve should the relief be? Anyone care to speculate on how many valves get tweaked in clearance checking process?

Dusty, trans is a bolt in. Low gear will be a moster as it is a 3.35 I believe.
Round ports are only good if the short turn radius can flow enough to keep the velocity from falling off. My ports are square.
The distributor is a Holley dummy for use with a crank trigger. There is nothing in it but a rotor.
Yes we coat the pistons and select other parts.
Depending on the valve material, usually you need at least .060 clearance around the reliefs.
