Hello, I apologize for probably not placing my writing in the correct spot, but classifieds seemed to be full of new products only, so I thought I would try here.

Have late model mild-build 350 (5.7L) with Vortec roller block, Crane roller marine cam, Edelbrock 750 carb, etc... estimated 400hp/400ft-lb @ 5700rpm in 17' Formula. Runs really good, and a pinch over 65mph still on incorrect V6 (1.84) outdrive ratio, changing to 1.5:1 soon.

I was running a Mallory Pro Comp 9000 distributor with internal magnetic pickup and module, but it is very unreliable, has failed twice so far. Internet is full of failed modules, so I am chalking it up to poor design.

Seeking used MerCruiser V6-xx(24 hopefully) ignition module to use with Thunderbolt distributor. I want the V6 as it will pull the timing curve ahead by 33% over V8 module.

Thanks.

I've got one. Its a 1987 350 Mag.

Email me @ [email protected] if interested.

Is it for a V6 enigne? I want one from a 4.3L, not a 350 (5.7L). I am going to use a V6 module on a V8.

When I get home, I will look at it to be sure, but I'm pretty sure it says "V6-24" on it.

I am flying today, but should have the info by Saturday or Sunday.

If it's a V-6 module, it will say V6-14.. But, when installed on a V8, it will only provide 8-10 deg advance.

You probably want a "V8 HP", which gives 20 degrees of advance.

Hi folks. Still seeking a used MerCruiser Thunderbolt V8 distributor, and module. Not sure if I want V6 or V8 module, seems a little confusing, some say V6 does timing advance earlier, but another said it will not advance as far as stated. I'm not sure about this.

If you have a used but working V8 setup, I'm ready to buy. Boat down for 2 weeks now. Thanks.

SmallPP

Cuda thanks for the words. Do you know why a V6 module will not advance as far as printed? I see some people use them here. What is the science with them?

I should have bought your 242, I called on it several times, but never made it your way to see it.

I replied to your email last week, but it must of not gotten through. I have the V8-24 module. I do not have a good distributor though. (I have one, but the pickup is bad, and the shaft bushing is about shot)

If you are looking for both, you may want to consider a MSD Marine RTR (ready to run) or a DUI distributor.

Let me know if you want it (the module)

There are several different V8 modules with varying timing curves. Some curves are 20*, 22*, or 24* and they vary on when they are at full advance between 3000rpms and 5000rpms. What kind of curve do you want?????

There is one V6 module(V6-14). It gives 14* advance on a V6 and about 10* on a V8 with all the advance in by 2500rpms.
