The abuse continues...

holy shit thats lift..so...will a valve actualy open that far?!?!?!? without smacking something IE the spring bottoming onto the head

yeah id take the valiant racing..youve indeed got EVERYTHING begging to simply be assembled
 
My only worry is a valve playing kissy-face with a piston. I'll have to get some Play-Doh and check that. Guide clearance would be a problem with factory heads, but I've got the ported long-valve W-2s to complete the longblock so clearance up top shouldn't be an issue. Rest assured, I'll check it first. I have a feeling I'm gonna need more valvespring, though.

As Stretch pointed out today, "We have to pull the K and engine to do the framerail anyhow. That's the perfect time to drop it in!" He's not wrong.
 
The way you got that motor is almost tantamount to rape.....:shifty:

Dude! You can't say that anymore.. Some pinko's gonna set up a crisis center on this board and have us talk about our feelings.

Bwahahahaha.....:bwuhaha:

"So how did that comment make you feel....bad right!".....Yeah it made feel like this.....:quit:
 
"Show me on this doll where the bad statement touched you."

Whether he knew what he had or not, he doesn't have it anymore. :dance: I plan on tearing it down and cleaning everything thoroughly before putting the boots to it, but I really don't plan to mess with the combo--unless it appears the size of the cam is holding me back. It's entirely possible it's overcammed, even with the big heads, but if nothing hits there's no harm in seeing what it does as-is first.
 
Did a rough compression estimate tonight after checking piston clearance @ TDC. It's not the most-exact measurement, but with a 70cc chamber and .025" gasket, the compression falls almost exactly at 10:1. While I was out there, I popped the balancer and cover off... hello, Milodon timing gears!

Bought today, those timing gears cost almost $440 by themselves, the pan is another $467 and the pickup (when available) was around $150. The pan appears used but the pickup doesn't, and though I didn't check closely it doesn't look like the timing gears have ever spun under power.
 
So, I pulled the camshaft out and after much searching I've determined what it is. Big. It's really fucking big.

It's an ancient Cam Dynamics grind, with 278°/284° duration at .050" lift. Lobe separation angle is 106°, and lobe lift is .413"/.427", which would be .620"/.640" with a standard-ratio rocker. With my 1.6:1 rockers, gross valve lift is .661" intake, .683" exhaust.

Thank God the Valiant doesn't have power brakes. Anyone got some Play-Doh? I'm not so sure I'm going to clear the pistons... :hmmm:
 
Check with some of the liberal colleges out West. I hear they have play doh.

That may be continental divide specific.. The kindergarten college I work for has no play doh. I think there was a problem with the students consuming too much of it. Drove up tuition.
 
10 second, street driven Valiant here we come!

I, err my wife has a recipe for a homemade Play Doh like substance...
 
Operating range: 4,400-8,200RPM
Recommended stall: 5,000+RPM
Recommended gear ratio: 4.88 or numerically higher, 4.56 minimum with small-diameter tire

I ain't so sure about this cam, guys.
