RPM drop and electric fans!

Yep… neither does my W2 Victor. I drilled and tapped the spacer .

Have a Holley W2 Strip Dominator and it does. My boat Eddie didnt! Senior moment.

Somebody Mention a Boat?

Balanced with Forged pistons, special Marine cam, head milled .080ths with mild port job.

350 chevy sized prop on the OMC Outdrive to capture the added power.

Ran out 7,000 rpm all day long, smooth. 47 mph (on the water) at full trim.

Did not have to touch the factory ignition or factory carburetor, was the right camshaft for the right application.

Thank you for this. My application isn't vacuum advance. One of the responses included a reference to vacuum. Appreciate the time and feedback!!

What distributor do you have?

Thank you. See if timing fixes your idle rpm drop problem and report back what your Idle timing ends up being.

Thank you. See if timing fixes your idle rpm drop problem and report back what your Idle timing ends up being.

Greetings!
Got out today and played a bit. Timing at where the idle was although all over the place hoovered around 14degrees and seemingly into the curve already. Pulled dist cap and rotor and there were 2 light silver springs. I swapped one out to the heavy spring and that stabilized the initial timing. I couldn't do the test you mentioned in the prior post as I was alone, but I gave it some advance to 21 degrees initial and that helped tremendously with the idle and fan combo. As soon as I have an extra set of hands will continue with your method.
So... a new question would be now is there anyone that makes bushings for the MSD to accomodate smaller advance curves? MSD's smallest is 18 degrees in the kit. Motor was dyno'ed at 35 degrees so where ever I land with initial, I will have to adjust range to work.

Thank you!!

See attached. Just ordered the smaller bushings for the MSD curve. Sitting at 21 degrees initial right now with an all in from the dyno at 35. The added initial helped a lot I have a 10 and 14 degree bushing coming. Will keep you guys posted on progress!!
Thank you again for all the help!!
