Socalman Posted July 4 Author Report Share Posted July 4 My confusion is I didn’t have to really force anything in, meaning I didn’t have to force anything in. If the trans was to be sitting level and not to the right, I would have to probably force it to be level?? If that makes sense? The engine looks level, but it would somehow need to be rotated left for everything else to be lined up on the rear end of the trans. Aside from my OCD with the shifter, everything seems to work and shift properly. Quote Link to comment
]2eDeYe Posted July 4 Report Share Posted July 4 The bottom of the oil pan should be level across right to left and a 5ish degree tilt running front to back. My mounts use 4 holes on the block. It drops under the oil filter. Quote Link to comment

]2eDeYe Posted July 4 Report Share Posted July 4 Oh I did not realize it was a Z block. I wonder how close it is to the KA Quote Link to comment

This is a pre 1980 71B 71B and only used on z, zx, 810 and 620 L series engines. The front case is from a Z series engine so that is correct for a KA as far as engine orientation or rotation. 2 Quote Link to comment

datzenmike Posted July 4 Report Share Posted July 4 Well it assumes the 510 engine brackets will work on a 521. Maybe the rubber isolator is thicker on the left side. No it does not look right. Quote Link to comment
datzenmike Posted July 4 Report Share Posted July 4 OK 521 and 510 engine brackets are the same. The 521 rubber isolators are the same part for both sides but the 510 uses a right and left and neither are the same part number as the 521. Which rubbers are you using? If the 510 rubbers are thin on one side and thicker on the other then using 521 rubbers is going to rotate the engine slightly for sure. Get the KA engine brackets that ]2eDeYe makes and compare them. Quote Link to comment

I’ll try the 521 rubbers, I am using the ones I got with the engine which I assume were the 510s but they were identical left and right. Will the KA brackets work for the Z24? Quote Link to comment
datzenmike Posted July 5 Report Share Posted July 5 No. I think 510 rubbers, might, I say might.... change the angle. Quote Link to comment
]2eDeYe Posted July 5 Report Share Posted July 5 I am going to say those fabbed engine mounts are whack. In this picture you can see the engine is at an angle compared to the square engine bay. This is before the trans mount is even installed. Just for more info. The 521 engine mounts are 1-5/8" ish tall and the 620 are 2" tall. I believe the 510 are the same height as the 521 mounts but not as beefy. Quote Link to comment

But I’ll fiddle with the mounts for a bit later today. Probably just live with it until someone makes better mounts for sale. 🤷♂️ 1 Quote Link to comment
Stoffregen Motorsports Posted July 5 Report Share Posted July 5 Not to add to the confusion, but I always thought the 521 mounts were taller, and they didn't have that safety lip. Quote Link to comment

]2eDeYe Posted July 5 Report Share Posted July 5 I think they are the same height. I know Icehouse uses 620 mounts in the 510 to get a little lift over the stockers when swapping in a KA. 1 Quote Link to comment
Socalman Posted July 5 Author Report Share Posted July 5 (edited) So I had one of each in, what I assume are 510 and a 521 or at least what I previously had as a 521. I tried both 510s and pan hit crossmember. So I tried both 521 but I couldn’t get one side to from enough to get holes lined up… I had to take some material off the left side mount bracket to get clearance as well as flip the mount. Looks and clears way better but now transmission tail doesn’t line up with mount. Just one hole Edited July 5 by Socalman 1 Quote Link to comment

Z and KA are tilted about 80 to the left of vertical. Quote Link to comment

Socalman Posted July 5 Author Report Share Posted July 5 Shifter is centered now… 1 Quote Link to comment
Socalman Posted July 5 Author Report Share Posted July 5 Appears to me, tilt is not the issue. It’s centerline. Am going to say because of engine brackets…but I am no expert on this… 1 Quote Link to comment
Socalman Posted July 5 Author Report Share Posted July 5 I don’t know what these measurements are supposed to be but it’s definitely not centered between frame rails….1.5” difference 3 Quote Link to comment
