Building a modular motor
Hello, I recently finished stripping down the carcass of my mustang (a 2003 gt hardtop with an A/T), (got in a car accident in a snow storm in 2013), and I've got the motor pulled and stored for the time being. My plan is to in the fall or spring to put the drivetrain into a kit-car, (probably a factory 5), or at least to start the process of building one. I loved my gt but after a while I definately felt like I was outgrowing it, I'm thinking maybe I want to build a motor but I would like to get some direction to see what would be the best combination of price/performance.
From what I understand, (and I could be somewhat wrong) is that I can pick from many of the motor components from mid eigthies (beginning of the modular family production) to 2010. I'm thinking I probably do not want to stick with a 2V motor, I'm contemplating doing a 3V or 4V motor.
So from what I understand with the 3V setup, these heads can be installed on my existing motor provided I get the timing cover, water pump, and all other required accessories and that I run solid cam gears with my existing ECU. I would probably go with some combination of high-lift cams, and use one of my existing machine shops to port the heads and provide larger valve seats. If I were to use the 3V setup, are there better heads to use than to start with a stock head and modify it?
I don't know quite as much about the 4V setup, I've read some different things saying that the 4V heads were compatible and some that said they weren't. I'm guessing that I would not be able to run the same ECU if I were to switch to the 4V setup on this. I would probably undergo the same efforts to maximize the performance of these heads.
As for the bottom end goes, I would probably try and get a forged bottom end with high compression pistons, (potentially just using a Boss 302 rotating assembly?) IS this feasible as the spacing is the same I believe.
So my questions are, what types of numbers can I expect from the aforementioned hypothetical setups, What would be more cost effective $/hp? I plan on sourcing many of the high value items second hand.
Thanks in advance.
