Proform HEI Distributor Review

Well I have ran into a issue with my tachometer.
It seems to bounce around at 4000 RPM.
While taping this video, I noticed it.
Anyone know what that would be?
Maybe I need a resitor on the tach wire?



watch at 3:56 to 4:06 into the film.

I tried using one on a 351W with an Edelbrock RPM Airgap and the body hit the manifold.I put an MSD ready to run in and it works great,no box needed.Put one on a 68 Mustang 302 ,worked for two days then went out.It took three weeks for them to replace it,had them return the money!In the interim put an Accel conversion in the stock distributor,works great!

Blueprint a DURASPARK II distributor and mount a TFI coil. Even rebuilding a points style with a PERTRONIX II would be better (IMO).

Hi all,

New to this site, has any one used the "PRO-COMP" electronics?

I've got a 460 in an (Australian) coupe (XB), and my mechanic has just ordered in a PRO-COMP distributor and coil and leads for me.
It is modelled off of MSD systems- but a lot cheaper priced.

Any feedback on these systems?

I have a MSD 6AL installed already.

Thanks

Just picked up one myself but havn't installed it yet. Procomp dist. msd and coil. I like the idea of two rev limiters. One for your top end and a button activated one for launch revs. I will get back after I test though it might be a bit as I am just starting a build. 77 F150 with a 400.
