TR-3550 or TKO??? Not sure.

[NitroStanggirl]

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
351 C DOAE Quench 4V Heads Ported
~ 64.3 CC heads before shaved about .020

And an occasional 100 shot of No2 Not enough to worry about
