Thread: Dyno video SBC 355

Tweet

Hi guys. Thought I read a thread on here about what sort of dyno readings to expect from a SBC. Cant find the thread. My engine is a 355 CI, 2 bolt mains with Holley 4bbl, Holley red top fuel pump, Crane cam (unknown spec), Edelbrock performer, K&N filter, MSD 6AL (5600 limit), Blue Max spiral leads, Blaster 2 coil, Pertronix ignitor, Pete and Jake gear drive and turbo 350 box.

Thought you might like to see the Deuce on a dyno last Sunday. Drove through a blizzard to get there. Total white with snow windscreen except the wiper area.....fun fun fun!!

First one is with the kick down cable connected. This gave an at the wheels reading of: 239.1 HP @ 5109 rpm, Torque 259 ft lbs @ 4442 rpm

Next one was when I disconnected the kick down cable ( keeps the box in 3rd gear for more accurate reading). This gave an at the wheels reading of 251.3 HP @ 5464 rpm, Torque 301 ft lbs @4035 rpm and a top speed of 118 mph.

Here is my readout.

Interested to here your views on running without a kickdown cable...I have not tried it on the street without kickdown.
