I bet most of you have forgotten about the Red 90 Talon in my profile so it is time for some updates and its Re-Build Thread!
Here she is...
About 3 years ago, the motor had a fit and bent all 16 valves on the way to a car show so she got put on the back burner. Well, now she is being resurrected to join the others in the herd. I don't have a build thread for her so this is a good place to start, I guess.
I had to get her motor out and tear it down to make sure there was no other damage, like to the pistons, crank etc. I noticed that the cylinders had some scratching on them and the engine barely had 1000 miles on it. I attribute it to butting rings on 40+ lbs of boost so this time around the rings all got hand gapped, all valves hand lapped, cylinders rehoned and all reassembled by yours truly.
The crank looked fantastic, as it should and the cylinders all honed out nice. I found some “artifacts” in the oil pan, namely the 3 oil squirters that had mysteriously broken off. Hmmmm
I procured a used set of squirters from a great member on here that has been my go to used parts man and sent my head to the machine shop to be re-surfaced. I bought all new SuperTech nitrided valves, a set of Kiggly Beehive springs and retainers and did all of the assembly myself. The valve job itself was done by my local machinist, but I do all of the lapping and final checks.
I ordered up a new set of ACL Race rod bearings and a new set of Manley rings to bring the shortblock up to as new status. When I took the pistons out (to make sure the rings would still float in the lands after crashing all 16 valves), the rod bearings looked GREAT and they should have but you never know. I gapped all of the rings for high boost and deglazed the cylinders which turned out very nice too.
I was about ready to close her up after checking clearances and my son noticed my oil pan had a baffle that was loose. I didn’t think I could weld it and have it stay so I just took tin snips and removed the part that was loose, we will see if that has any effect on the motor.
So after another once over on all the parts, I grabbed my favorite RTV and got the oil pan ready. It went on smooth as a whistle and currently I am at the point of getting the HLA’s, rockers and the new set of Kiggly 272 cams in the head and it will be motor assembly (fun) time. Stay tuned as I plan to try and have her back up and running this spring. She has a 3rd gear grind that I have to address but then she is ready for stalking the streets again with her QM twin this time around.
A few extra pictures..........
