  View original topic: Which Vac Distributor to use
KennyK Mon Aug 04, 2014 5:31 pm

It was recommended that I use a Vacuum Distributor with my 1641. I checked my inventory and I have 3 to choose from
1. JU4 0 231 147 002 111 905 205M

2. JFUF 0 231 167 070 113 905 205AN

3. JFUDX 4 0 231 174 005 002 905 205F

# 2 & 3 both have 2 vac ports on the Dist.

Which one would work the best for the 1641?

what cam and carb do you have?

Yeah, what he said. ^^

If you have the stock cam and carb, then the stock distributor is your best option.

I layer out the motor in my post asking about carb choice and It was advised to run a 019 if in budget and if not I should ran a vacuum advance distributor.
1641
34 carb
FC400 cam from Fat Prefomance
New Stock heads with some clean up polishing and deburring.

I am not familiar with that particular cam. If it is a pretty mild cam the stock DVDA distributor should work.

With a 34 PICT carburetor you can definitely eliminate the 111 905 205 M distributor. It mates to a 28 PICT carburetor.

I like the 019
