200 I6 rebuild for Turbo sugestion's?

[matt1967]

I don't know what I'm looking at for power, but probably in the range of 200-300 HP.

That won't kill a trans or converter anytime soon.
It will actually depend more on how much torque it makes, not HP.

That's true. how much torque do you think it will have. stock they have 190 ft/ lbs but that's with 9.2:1 comp ratio N/a. could I be looking at 4-500 Ft/ lbs?

When my went into second gear, it was so much it felt like 400 easy.
Bogging a turbo car down when already fully spooled increases torque a BUNCH.

Throw a shift kit in it and pull it/fix it when it breaks!

Even if the internals hold up, I wonder about the valvebody.... there were different versions. Some are better than others.

Probably best to not worry about it. Get it running first and fix the parts that break downstream later.

I think I'll do that. after this is done, I'm gonna go find sombody with a dyno, find out what it does. or should I break in the motor first, other than breaking in the cam? Also being the static compression is going to be around 7.5:1, what cam do I want? another stock cam, or can I go a little hotter.

I would never go that low of compression, even on a turbo motor unless you were wanting to boost over 20 psi. It would be a dog anytime it wasn't boosted.

Go with at least 8.5:1. I think my factory compression '82 model 200 was rated at 8.8:1 and that was fine running 8 psi on 93 pump gas.

break in the cam for a half hour (get a 214/214 @.050" cam, I think its a 270/270 but not sure right now).

I like to drive mine the moment it starts. I've done enough engine builds and swaps in my life I know all the things that can go wrong in the first few minutes. Instead of doing thr generic half-hour cam break in, I go drive it for a half hour.

according to the specs on the page for the Falcon 6 performance handbook, '78 up engines had 8.0:1 comp ratio, that would make approx 11:1 dynamic compression ratio at 8 PSI boost, generally the limit for 93 octane is 12:1, you could have probably boosted to 10 PSI saftly, and run 93. I think I'll shoot for 8:1 and run 10 PSI. I was thinking about the motor dogging without boost.
