When I bought my new 370 injectors I put the thick washers on and left the thin ones in the box. Would it be big enough difference to be worth putting the thinner washers on instead of the thick ones? I used the thick ones because that what the stock injectors had on them.

If I remember correctly, the thin ones (should be about 0.020") will put the spray closer in the piston bowls. It should reduce smoke too.

PDR once told me that the difference between thick and thin was about 25 hp on a dyno. Use the thin

Go with the thin ones. I did the same thing you did and then had to pull them back out and put the thin ones on.
