I see the 142's advertised for 350 sized engines and the 177's are for larger displacement like 383, 400. I imagine because the 177 moves a lot more air..
My question is would it be possible to use a 177 on a pump gas mild cam 350 by using larger heads, lower compression, swapping pulleys, or a combination of these?

 

yeah , why not?

i think its okay to use larger blowers, too small would be a problem, but i dont think you can go too big.

With too big of turbo's you can get a problem with turbo-lag, but thats not with blowers.

gotta love blowers!

in my opinion the 177 would work great.

 

yes, thats what they sell it for.

 

Like stated earlier it shouldn't be a problem. A 144 to 177 ci isn't that great of change. Going slightly bigger would allow more upgrades possible in the future. You could get a tad more out of the combination before worrying about the blower being too small.


There is a certain point you can go a little too big. That's only if you try to go outrageously big. It's due to the blowers actually have a small amount of leakage at low speeds. So to put a huge blower like a 8-71 on a 305 it would have to be turning slower than if you used a 4-71. There is supposely greater clearances for leakage to occur.
