Thread: sbc with a 177 blower

Tweet

Jay, you are aware that it is the teeth on the Gilmer belt hitting against the faces of the pulleys that make the whine, right?? If the smaller blower uses conventional belts, it will be pretty quiet.

Adjust the c.r. with either piston volume or combustion chamber volume according to these instructions.....

Adjust the deck height and gasket to achieve 0.035" to 0.040" squish to keep detonation under control. Also look into some of the water injection systems that are available.

You'll notice that Blower Drive Service suggests no more than 6 lbs of boost at 8.5 to 9.0 c.r.

ive seen guys punch small holes in between the teeth with a small drill bit to let the air out quites them right down. funny how that tidbit is often overlooked learned it when i was like 6

The 177 blower will work but the belt set up makes me nervous.
I would save your money and buy a 6-71 for a few hundred more.

I couldn't agree more. Bang for the buck, you'll get better results with the 6-71.

Erik's right about the rods. If your budget allows, I'd buy a top notch steel rod and a good piston no matter what you do. Along /w those aluminum heads, a tougher piston and a stout rod will help any detonation problems because your motor won't go to pieces at the first sign of trouble.

I heard a good quote in the snap-on thread "Buy quality, and you'll only cry once"
This goes for almost everything
