Rearwheel HP on a stock 1967 289 Mustang Fastback?

**tminus3** · 11-19-2002, 04:21 PM

I was wondering what kind of rearwheel horsepower a stock 289(4v)Mustang with powersteering, AC, thermactor, stock single exhaust and C-4 transmission would be getting?

probably no more than 190

I would say, with single exhaust and all stock, no more than 140. On a good day. I've got a 2 barrel, which is similar, and I'm sure that thing is not putting out any more than 120-130.

About 130-140 if tuned really well in stock trim.

I was expecting around 150, so it looks like I might not be far off.
I'm restoring a 1967 Mustang fastback, and will be rebuilding the engine too.
I was thinking about adding dual exhausts, Pertronix ingition and coil, maybe put in roller rockers and having the heads ported (for free) ass well.
I'll probably get the chance to put it on a chassis dyno, so was wondering what kind of performance it would get in completely stock trim.
