tii dizzy and header upgrade, why?

[dma]

Have seen the tii dizzy and header as common upgrades to stock rebuilds and just wondered what you got from those changes? Many thanks in advance for your comments.

I installed the Tii exhaust manifold to eliminate my Thermal Reactor oem unit. It appears to have slightly better flow and weighs a lot less. Car runs better, but that may be misleading because I had a number of leaks due to partial and jerry-rigged desmogging.

The Tii dizzy lacks a vacuum advance and you can 'tune' it, or more precisely, 're-curve' it using different springs/weights to move the advance around the rpm range to optimize your individual setup.

Cheers!

+7 HP if you use a dwell meter,

timing light, and exhaust A/F ratio tester.

+23 HP if the motor was in krap condition

and now it gets correct attention (that's +23

to the lousy runing 70 - really)

now hold on there just a 'cotton-picking' minute....

i had nothing to do with desmogging your car and the 'alleged' airleaks.

sheeeesh....................

Thanks guys, appreciate the information. I guess that $20 header in near perfect shape was worth every penny. Now to find the tii dizzy....

I actually think the tii dizzy's not right for a carbed car. It doesn't have enough

total advance, and won't give you enough advance at light- throttle

cruising.

In EFI terms, it's missing an input- it doesn't know where the throttle

is.

Having said that, CCD is right- any dizzy in great shape is better than any

other worn- out dizzy.

fwiw,
