Re-restoration in progress for some vintage racing

[Horseplay]

Cool! So where will compression end up now? The ported rings are a cool move. I had read quite a bit about them and am interested in their real benefit. The switch to a roller is pretty significant. Quite a bit to be gained with the crazy ramp capabilities compared to a flat profile I'm sure you'll be able to take advantage of the added Carb cfm. Will you put it on a dyno to document the improvements?

It will be broken in and tuned on the dyno. We’ll test the new 750 vs my current 650. Hope to head down in the next week or two. I don’t have the numbers on the CR yet.

 

[msell66]

Results of the dyno tuning are:
380tq at 5,500
451hp at 7,100
The super cool 750 added Zero to those numbers. I think we’ve found the max out of those 289 heads.

Finally got the engine home. Sadly, this spot is its home until April. Winter sucks.

That one bolt looks funny...

Just one bolt? I like the way he doesn't keep to a theme. Socket head cap screws, hex head bolts, the kitchen sink

It’s just the lighting, morons

Heated and beat the headers into submission. Now, all but the rear bolt at #8 uses a socket to tighten.

Lighting?

Who gives a crap about that? Bolts are bolts. As long as they hold parts in place.

Buncha weirdos

My original comment was just an attempt to get ole 's OCD to kick in and see him spend a couple hours trying to figure out what I was talking about. Maybe I should have asked about that oil leak instead.

Who you calling old?!

I call BS on that and know you know better.

If bolts are bolts and just needed to keep things together, did you use different bolts for the connecting rods?

Yes. I used ace hardware stainless steel phillips head.

Graphed out the dyno data.

You can really take a 289 up to 7000 rpm????

I spun the old 289 engine to 7,500 for 6 years before it went boom. This engine has a 302 block and bottom end. It’s limited by the 66 OE 289 heads. I’m spinning this one to 7,700 so it’ll last. It’s built to turn 8k+
