Streetmaster 318 vs. Performer for street use

thanks guys,

the idle screws out '3 turns' , I meant 1.5. That's what I have them set at now, time to bust out the vac gauge and set this thing properly and double check the power valve too.

See here at 1:14 or so...

Good advice to fine tune those, will do.

Also checking the accel pump is on the list.

Fishy68:

The lowest octane fuel here in the Netherlands is 95. That's why I run 95, it's all there is.

I can run up to about 6k at the moment without issue with this setup. So that's more than enough.

My compression is @ 9.5 to 1

I'm gonna take your advice on the timing as I'm not sure my secondaries are even opening properly or fully. I've got to do the 'paperclip test' to check if and how far the secondaries open.

My 'fascination' with Edelbrock's is that they are simple, don't have power valves that blow and are generally easier to dial in on a street motor. On the other hand, if you take the time, a Holley is a very flexible carb that you can dial in specifically. Hence the poll.

I suppose one is a sledgehammer, the other a set of hammers w/ specific applications.

I was actually thinking of putting a weaker spring on my secondaries, this is also something Holley advises on light cars meant for performance...

I'll order a spring kit, mess with the accel pump cams and definately follow the advice given with regards to the Idle mixture, pump clearance and vac advance.

Questions leave me with questions:

1. If I dial in more advance on the pod I need to dial back my initial advance correct?

2. Why would a rich idle cause the stumble?
