Anyone Dyno their cars after swapping engines
such as 350ho, zz4 and etc. Lets see some posts with the results.

 

All these engine swaps and no one has Dyno'd
their cars to check RWHP. I bet Kevin 91z
can show us what his car Dyno'd at.
Anyone....

I had my 305 dyno'ed, but I personally don't consider it to qualify as a "swap". It's the original L69 block with different heads, a roller cam, TES, and most everything else (carb, intake, exhaust, air cleaner, all emissions stuff operating) exactly as it came stock. As a brand-new motor, with 8 miles on it, it passed CA emissions a few days before it went to the dyno.

It peaked at 214 RW HP @ 4500 RPM and 282 RW ft-lbs @3300 RPM, which works out to about 260 or 265 crank HP peak.

OK, I was able to have my new 350 dyno'ed before putting it in, but I haven't had it on a chassis dyno since it's been in the car.
With the chip I have in the car and same TBI setup my 350 put out 417 ft/lb at 2500 and 312 HP at 5000 RPM.
This is with SLP 1-5/8 Headers and a single Flowmaster 3" 2 Chamber muffler,The custom Fastchip Prom and fuel pressure at about 20PSI.

So my CC-carbed 305 runs with your TPI 350, żeh? Now I don't feel so bad for nutting my poor car. Still, you didn't do too bad, you got 50 HP or so extra out of it.
