Yep, Tanks Inc, I think it's the smallest FI pump they sell.

@ Thank you! 👍🏼

I was just trying to check it, to see if I my installation was way off, looks like the timing is slightly advanced by approx 2 degrees, I decided to leave it. The error could just be my measuring setup, or my finding TDC. If it's truly advance it might result in a little more bottom end. I did the video because there were no vids for this type of procedure on this engine, thought it might help. I"m definitely not an expert....

that's how the cam maker specs it, at 0.050" lift, pretty common way of doing it

It doesn't yellow like nitro. Probably harder than poly, but not sure. I have guitars that I finished about 20 years ago, they look pretty much the same. On mahogany the pores have shrunk a little which I think is more attributable to the pore filler than finish. I'm going to keep using it until I find something better. thanks for the question

@@joem6859 thank you :)

where you at?

come see my collection lol

You can find the lighter springs at your local engine shop, they might have to order them but they're specifically designed for this exercise.

thanks for the kind words

sorry, don't know too much about sbc's and what trannys will work or not work

Hey... how you doin? Yeah, I'm in the process of trying to start the motor shortly, maybe next 2 weeks. Have some debug to go thru with the MegaSquirt 3, a few other things to check, then we'll try to light it off!! And yep i'm in the Church as well. May post to both YT and the Church. Thanks for asking. How's your project doin?

yes... picking geometries for toolpaths can be vexing, to say the least. Try not picking any geometries(i know it sounds crazy) and see what you get. Check out Lars Christenson on YT, he's awesome, many videos on Fusion

Hello Ken. I don't think there is a 'right' or correct position for the stop. As long as the stop is positioned some distance below top dead center, like maybe a 1/4" or so. Of course you have to take into account what type of piston you're using. The change in piston position, vertically, with relation to crank angle decreases significantly as the piston gets closer to top dead center. Just the nature of a crank mechanism. If you're farther away than 1/4" it should improve your measurement resolution, if that makes any sense. If i could do it over, I would have installed the flywheel and some marks to refind TDC later for cam timing. Would have been a little easier than the same exercise thru the spark plug hole. Gotta keep learning...

Hey... just finished the build and troubleshooting of a Megasquirt 3 EFI unit, working on the power feed, relays, wiring now. Build engine run stand for it as well, maybe fire it in a month?? maybe...

Well, good luck, glad I could help...didn't see much on this subj for overhead cam engine so I took a whack at it

@@joem6859 Well it was a pretty darn good whack.

@@novakenss thanks again, good luck

I did get my cam changed from a Comp Cams road race grind to a street performance spec grind. I had to resurface the rocker arms first. I tried many ways to verify the Intake and exhaust lobe centerlines. I tried .050" on both sides of the valve opening/closing but the numbers I was getting seemed off by about 14 degrees from the spec of 110*. I then tried .050" on either side of the tip of the lobes and got about the same results. I was concerned that the cam was way off. Then I read about symmetrical vs asymmetrical cam lobes, noting the uplift ramp is very different from the down ramp which allows for a more gentle valve closing to be nice to the valve seats. The rocker arm ratio changes throughout the cycle and the asymmetrical lobes help to accommodate that also. I finally ended up just looking for the maximum lift point of both intake and exhaust and presto, I was getting 110* just like on the Comp Cams spec sheet. I poured on the cam, a bottle of zinc oil from Comp Cams and did a break in run for 30 minutes at 2500 rpm. I have triple Weber 40 DCOE's and now it idles way better and is easier to jet and set the idle speed. I'm having my distributor rebuilt and recurved by Advanced Distributors in Minnesota so I can't drive it until it gets back to me. Now on to the next upgrade; Electric Power Steering. My wide wheels and tires require it. I do like working on my Z.

@@novakenss very cool, good luck.

Thanks for the kind words. Fusion360 is awesome, i highly recommend that you check it out. Very powerful modeling and CAM abilities at a very reasonable price, free if you're a hobbyist!!!

Hi, thanks for the note, i'll try to get a vid of the assembled bench by end of the week
