Softened the curve a bit from 1500-2500 . All in by 3k @ 3200. Played with the VA as well . My idle vacuum is 9” and light cruise 15” . Higher speed max it out around 18” . I have an 8.5 VA can and set it to come in around 10”. Next up is more carb tuning . Idles in low 13s afr. Cruises in...

Oh yeah … I dropped a set of 3.91s in it and that helped low end . Lol

This 408 is running ported W2s flowing 297 @ .650 and 1 7/8 TTi headers . I have run my 800 AVS on it and found it had a bit more low end but worse everywhere else . I could set up a 650 DP for running around town and use the 850 if and when I go to the track I guess .

I sold my Pro Dominator to a member that made me an offer I couldn’t refuse . He was having Jim Laroy build an engine for him . Never heard how it turned out .

Thx ! I am running VA and will check out your thread. If you know where it is off hand and could post a link that would be great.

And you believed correctly. Much better off idle torque with the current curve . I will continue to tweek it over the next few weeks .

Yes . Now I need to adjust the idle circuit.

Remapped my curve and it definitely helped. Might need to back off a little at 2000 rpm.

What is your curve like ?

Yes . I will need to break out my laptop when I get home later today .

That’s good info . The engine can idle around 750 but I set it at 950 to keep solid rollers happy . It’s easy enough to change my curve I just haven’t had the time and wanted some feedback before diving into it .

...timing really is a reflection of and determined at high rpm performance. If the engine doesnt perform any better at 34 than 32 why use 34. Unless you are suggesting the engine might want 34-36* at 4000 but 32* at 6500…. Which would be possible with my digital ignition . That would be...

185 cranking

4 speed 3.55 gears although I just picked up a set of 3.91s with clutch style sure grip .

True for many aspects of tuning but wouldn’t wide open throttle at max rpms under load be similar in both cases ? In the car engine bay heat would become a factor but that would call for less timing I would think .

I don’t consider 246/250 to be a long duration for a 4” crank but maybe your right .

My W2s are closed chamber race heads with .040ish quench . Anything more than 32 yeilded nothing on the dyno . Surprised the dyno guy as well .

That he is . But not sure if he is the Tuning Guru . Guess we will find out

The 408 in my Swinger seems pretty lazy at lower rpms and I am thinking its my timing curve . I had the engine dynoed but that only covers 3000 - 7000 rpms . The build is as follows W2 heads ported 246/250 @ .050 / .648 lift on 108 solid roller W2 Victor intake 9.5:1 compression 850 Pro...

Besides the $$$$$ MSD light its hard to find one that works on multispark . Strange since there are so many cars with MSD style ignitions .

The Innova will not work with MSD style ignitions .

Excellent thread !

Too technical for me to follow. Why not just install a switch in the iginition circuit ? Use a flasher switch that matches your year and model . Thats what I used for my electric fuel pump and 3 step burnout rpm limiter.

No I meant entire B/RB distributors.

I have a bunch of spare small block distributors ( would like to acquire some B and RB ) and parts including new reluctors, pickups, various advance plates and rotors , spring kits etc…. I follow your posts and try to learn what Ican .

Nothing wrong . I will solder a distributor plug to the boxes wiring and wanted to get it right the first time without a lot of messing around soldering then resoldwring . (******* spell check !) thats it I am turning it off ! ….

LOL…. Duh… I really do know the difference between a reluctor and a pickup

Is there a way to verify the positive/negative terminals of the reluctor with a multimeter ? I know the wire colors are sometimes mixed up or different.

Cool … maybe I can get up to 8 mpg then . Lol Is there a specific type of coil I should use ? Can I just unplug the existing Mopar electronic from the distributor and plug the Jacobs in ?

Saw this on CL for $20 and figured it was too cheap to pass up. Plan is to use it for my 78 Dodge Motorhome 440. It did not come with a coil but I have many coils including an Accel Super Coil and a Ford unit that came with an HEI setup I got from Trailbsast .
