TR-3550 or TKO??? Not sure.
			 
			 
			
		
		
		
		Hey, 
 
Anyone want to help my indecisiveness? 
 
If I call someone for support they may try to lead me in the one that makes them the most money.  I don't know whether I will need the TKO or not, because I really don't want to spend that kind of money. 
 
I don't even know what my estimated HP and TQ will be!!!  If you guys want to help me out with that estimate that's fine too. 
 
I've got anywhere from 400-540 hp and 415-515 lb/ft of torque, but I don't know. 
 
Do I need the TKO? 
 
I don't know what this motor is going to do.  I think my biggest part of the horsepower equation is I can't figure out my compression. 
 
Here's what I've got going on bottom to top...: 
1970 Mustang Fastback

~ 64.3 CC heads before shaved about .020
