As part of my NewYears resolution #2 (getting one of my vintage mustangs on the road) I have to finish an engine build that I started about 1 1/2 yrs ago...
Block is a new old stock FMS R302 siamese bore racing block that can go 4.125 but I am sticking with 4.0 and have the pistons. Ring stack is a metric size (1.5 1.5 3.0) with support rails since the pins are in the oil ring groove slightly. Rods are 5.4" and the pin diameter is .927 (heavy pin option for spray or boosted applications), compression height is 1.090"
THe block comes semi finished in many ways, it had to be line bored, the lifter bores were finished and the cyl bores were around 3.980 if my memory is correct.
Crank is forged 4340 and the rods are Hbeams, both from Eagle...
I had custom pistons made to go with the Aussie 2v cleveland heads (making this what is known as a CLEVOR) which are mucho better for street/mild performance than the 4v close chamber (boss 302) cleveland heads.
There is an off the shelf cam that I am going with to baseline this engine, hydraulic roller, and I will use the best lifter I can afford. Intake and cam may change down the road. I am going to run a pair of TRI-Ys with custom flanges to fit the cleveland heads (already have them).
THis will start it's life with a carb but I am going to weld in the bungs for injectors and sensors that I need to run Mass Air FI.
Goal is to hit 450 ft/lb of grunt over a broad range and 500+ hp.
Trans is a t56 2003 cobra six speed that is getting REgear and upgrade to viper spec parts (double overdrive .5 ratio , better forks/bronze pads, new gears). Rotating assy has to be balanced so I have to get the flywheel/pressure plate/clutch disc/hydraulic throwout/slave.
I have to get the cam plus these two parts to resume forward progress before I can start mock up and make a few little updates on the block before finish hone on the bores...
Pics to follow as I get started again.....
