Distributor advance springs

[Terry Hauck]

Hello. I am building a 440 for my 69 Roadrunner. It is a motorhome engine and it came with an extra forged steel crank. It has that crank, a 509 cam and about 10.1 comp. I have the electronic ignition that came with it in 76. Took it apart to clean and lube. It has two different springs. What do you guys suggest?? Thanks

If you have access to a distributor machine you could see what the curve is vs what you want. Or do it on the motor watching a tach and timing light to see what rpm its fully advanced, kind of an estimate.

I can do it. 100% needs to be curved to your engine. Motor homes are tourk usually and a smog motor. PM me.

He's the go to guy for distributor stuff.
Just move your cursor on his name and it says "start conversation".
(Or click the link I gave. Same, same).

Got a set of springs from Halifaxhops according to the numbers on my distributor and my engine specs. So far it runs strong. He knows his stuff.

I had to change one spring on my MP distributor to a heavier one as my advance was starting to coming in at idle.
