4.1 stock block build

[Mike Licht]

Block prep was done and we washed it good, Crank is installed and we used a 5 pound dead blow to set the thrust, it scares people to see this happen but it must be done I have found. Pistons are on the rods and the rings are getting file fit now. If it was not 100+ in the shop it would be together

Be glad you're not in GA. I've been porting timing covers for the last two days! Can't wait for it to get hotter! lol

 

[dr_frankenstein]

you guys are fast big boys! how is that you dont have an A/C in the shop?

 

[dartguy340]

Back when I was porting cylinder heads the owner put
a 5,000 btu a/c in the window. My room was only about
the size of a 1 car garage....had to wear a long sleeve shirt
to keep from freezing to death!

Who needs A/C? They didn't have it as a rule 100 years ago and lived just fine.

 

[Pronto]

And they died at 35...

I bitched about porting timing covers outside back then too

Ya screw that! I got a nice little swamp pumping along to help keep the dirt out of the air and cool the day off. makes building really pleasurable. no need to be He-Man just to bolt a few parts together in the heat.... turn on the A/C and concentrate on what your doing... not dripping sweat all over new gaskets.

im sure its dry enough for you to use a swamp Charlie...

Why does this thread have such a hard time staying on track?

 

[Mike Licht]

I wish I knew,

Where are you looking to rev this motor to?

[Mike Licht]

around 6000 or so, we will see what the XR5 cam does in this motor. I have a bigger solid roller on deck if I need it, I will likely put that in down the road

is it solely the cam (and valvetrain of course) that determines where these motors can rev to effectively?

 

[Mike Licht]

cylinder head will be a factor at some point too

 

[Mike Licht]

the pistons are installed, the cam is in and degreed, the heads are on. I resisted the urge to install a big cam which is what I usually run on my personal stuff, to use our new XR5 214/214 cam. It has very agressive lobes and will be .565 lift with the 1.60 rockers I am using along with the Champion iron heads. The .200 duration of this cam is as big as some of the .224 cams.

 

[ek02]

What is the duration of the XR5 214/214 cam at .200 lift? What was the piston to valve clearance with .565 lift and 1.60 rockers, and what compression ratio did you end up with?

 

[Mike Licht]

compression is 9 to 1 almost on the nose. the pistons have lots of valve relief PTV is fine, the .200 number is in the 140's
