I messed some more with my carb and dizzy....

FWIW- that Mallory Hy-Fire box is also sold with Summit's brand name on it for about $50 less than the Mallory box- same stuff, different wrapper. And it works just fine on Ol' Red. No really noticeable improvement other than it did clean up the idle a little. My main reason was the rev limiter.

And I have to wonder about the advance/hard start thng. I'm running close to 18* initial and Red will pop off right now when it's hot. Original GM starter that was installed in December of 1968 when it was built. And that's never been apart.

Hi Tim, I'll mess some more with the timing and try a little more advance. I'll need to get one of those timing tapes - that should make the job a little easier. I am trying not to make too many changes at once. the carb seems to be finally setup correctly, I have the new advance can and the heavy springs on the weights....
With 18* initial (with or without vacuum connected?) - what's your total advance ??

Should be 36* mech, 52* total with vacuum. 34* with fast burning heads.

I don't have any vacuum advance. Total is right at 41*. remember that I'm running 12.5:1 compression, lots of cam, aluminum heads, and 110 octane gas too. I've played around with timing a bit and the BB seems to really like the 39-41* so there it is.

That explains it... I was wondering what vacuum can you have and what centrifugal springs you're using with 18* initial LOL

They were BRUTAL also. Tim's Big Red runs hard and attracts a crowd where ever he goes--at least here in Kalifornia. :smash::thumbs:

What that song?? 'Where have all the hotrods gone?...Long time passing'....something like that.....

not that the new ones aren't better, but they ALL could be better YET, both in MPG and overall engine performance....

but my suggestions would not be PC, so will never fly....

If I could afford a correct fuel injection system I'd probably give that a shot too. No problem with the new tech stuff, but it is fun to fool around with the way we did things 30 years ago too.

Heck, if I run across an old Crower/Hilborn mechanical injection, that brand new hood is going to be hanging on the wall next to the old hood. I'll find an old junker hood to cut a hole in.

I have seen pix of Stu's finest with electronic injectors off the side where the old pissers went....

I had a mega buck laying around, it would be on my car NOW....

Someone here was selling his big block crower w/ calliope stacks, don't remember who it was though.
