Well, good news and bad news. The good news is the crankshaft guy will be ok... the bad news, he had a what he thought was a heart attack while grinding the crank and has been in the hospital since Tuesday. Seriously you can't make this stuff up! Also, the spring cups I have are going to need some serious machining to fit. Did work on the rods today to start measuring bearing clearance.

I think this would be a good jumping off point for head flow on a 882 casting @ 28 inches 4.060 bore

.200 130
.300 188
.400 218

That head would make great power, or so I'm told.

Two sets of spring seats neither is close. Thank you Comp for putting the wrong set in the right box!

Stout heart, Todd and Autumn!


Back in the day we used to say, "IF it doesn't fit and it isn't on time and it costs too much it must be race car parts" and evidently the people side of the equation is pretty much the same.


Keep on keepin' on and it will work out. Grab adversity by the scruff of the neck and beat him to death with a handful of the details properly addressed!


Regards,
HB2

I have a crankshaft in my hands, I also have a set of spring seats that will take the least machining.

Wow this is dragging on! I just move slow because I don't trust I'm doing everything right so I ask a bunch of questions. Anyhow, checking bearing clearance, assembling pistons and rods, starting spring seat machining. I asked PAC what everyone was doing for the 1409x spring install in these heads, he said "although we wouldn't recommend it, most are just throwing them in the head with no spring seat or cup". I just don't know how you guys that build your own engines can possibly do this without a machine shop at your house. Back to it tomorrow, at least for a couple hours.

Not much done today, Main bores are slightly off so I ordered a set of main studs and I'll have to align hone it. Won't happen till Monday.

Test fitting wheels before mounting, just a LITTLE close on the left side shock mount.
