Re: AJ's '72 Cruiser Crawler Build
If Keith Black's compression calculator is correct, I should end up right around 9.9:1. I'll probably get it dyno'd to dial in the final tuning of the EFI.

Re: AJ's '72 Cruiser Crawler Build
That's awesome, I've always wanted to throw one of my engines on a dyno, you'll have to let us know how it goes.

Re: AJ's '72 Cruiser Crawler Build
Not a whole lot going on right now. At home recovering from surgery to correct a deviated septum. But I did pick this up... reconditioned tilt column with new levers.

Re: AJ's '72 Cruiser Crawler Build
UPDATE 11/23/09: Septoplasty recovery. I took all of last week off to recover from surgery. By Wednesday, boredom had set in. By Friday, my wife ordered me to the shop to get out of the house...like I was gonna argue.
So...I took it fairly easy and painted the block, upgraded my seriously wimpy bumpstops, pulled the old steering column out, and removed the floor shifter. Hey, anything is progress at this point, right? Block all masked off...its like turning a 4 year old loose to wrap Xmas presents. Masking pic just for you Kurt Three coats of Duplicolor High Temp Engine paint red later. Much better than the previous block's purple, I think. Bumpstops. more to come... |

Re: AJ's '72 Cruiser Crawler Build
Good progress if you ask me. Nothing better than a freshly painted engine. The bump stops looked pretty beefy, I like them. Glad to here you are recovering nicely.

Re: AJ's '72 Cruiser Crawler Build
Manged to get off work early today and made a little more progress on the engine.
Measured up a set of pushrods...they're on order now. Then pulled the timing cover back off to put a cam button on. Turns out they're kinda optional on a flat tappet cam. However, required on a roller cam. After that, the balancer on went on...fighting every inch of the way. Then started to test fit the new headers. I ordered a set of Hooker Comp 2455s. They're for a 1972 Chevelle and are supposed to fit well. However, I ran into several clearance issues on the DIY4x crossmember. I may need to go back to the factory crossmember. I chucked the old one a while back cuz the PO had mangled it up getting the old engine in. Need to find a factory crossmember... New cam button Last edited by AJs72K5; 12-05-2009 at 07:17 PM. |

Re: AJ's '72 Cruiser Crawler Build
Engine looks great, really like the flat black look. How about exhaust manifolds instead of headers. You must just be itching to get that engine back in. Are the small block and big block cross members the same???
Liking the bump stops also, where did you find them?

It had a small block crossmember in it before. I know there are different engine stands, but the crossmember itself is the same. I'm gonna hit the local PickNPull this weekend to see if I can find one. I bought the bumpstops from a member on another board. We haven't figured out what kind they are yet. And to answer your question from before, no, a big block does not use a thrust bearing behind the timing chain. You can put a wear plate and thrust bearing behind it if the timing chain has chewed up the block like my old one did. But you need to mill the surface flat first.

Re: AJ's '72 Cruiser Crawler Build
What kind of motor mount do you use with the original cross member? I was just going to get what ever came stock, is there other options?

Re: AJ's '72 Cruiser Crawler Build
Update 12/05/09: The motor mount crossmember plan. Did a lot of thinking the past couple of days on how to handle the headers not fitting with the DIY4x crossmember. I didn't want to cut the headers...if I ever needed a new set, I'd be looking at customizing them again. I wasn't crazy about going back to a factory crossmember either. So, like any good K5 owner with a build thread, I figured I'd fab my way out of it.
Headers on, you can see that I'm roughly 1 1/8" away from seating the crossmember to the mounts. So, I trimmed the flange down 1". I'll have to redrill the top holes, but that's no biggie. Why didn't I seat the crossmember all the way? I'm going to have Kert fab up some new motor mount brackets that will raise the engine 9/16". Still not there yet, but I already knew this. Next, I'm gonna push the frame boxes deeper into the frame by 1/4" and put a spacer in between the flange and the frame box. This is how I should end up clearance-wise. There's about 1/8" - 1/4" between the header and the frame box. The pic just has a scrap piece of 1/4" steel to represent the clearance of the new spacer. I'm happy with how it turned out. So, I took another picture of the motor... with the real camera this time. |

Re: AJ's '72 Cruiser Crawler Build
its almost home! I can hear it run now
Maybe Diy4x(kurt is it?) should think about making a specific cross member for the big block conversion there seem to be alot of us out there and nothing seems to fit just right yet

Re: AJ's '72 Cruiser Crawler Build
UPDATE 12/13/09: We have pushrods!! The new pushrods came in this week. I got them all dropped into the motor. Last thing to do on the engine is set the rocker arms and bolt down the intake. I figured I'd also drop the oil pan and give it some fresh paint to match the block.
Comp Cams Magnum pushrods. They feel beefy. Freshly painted oil pan...drying in the garage. For those that wanted to see the full sweep of the headers on the engine. Here's both sides. Just another excuse for me to take pics of the engine. |
