I like that laser setup. I use a couple $7 lasers for my alignments.
My bracket base is parallel to the centerline of the car. Toe measurements are consistent because my reference stays the same. Bump steer like I just did takes forever, but that doesn't happen very often.
Most racecars have jigs that pin to hardpoints on the chassis, and hang monofilament down each side. Indycars use dial calipers to measure toe and ride height.
The short block is almost done, but I noticed something wrong - it only has 8 piston assemblies installed. I sat down with the builder and said he has a math problem because he can only count to 8 and there's 10 holes. He laughed and said its because 2 of the bearing sets were too tight (mislabeled boxes) so he's waiting for new ones.
He had to hone the main saddles because Clevite didn't have the half-size he needed in the series he ordered. So, he made a little more clearance for the standard sizes. FYI, the Viper's mains are a whopping 3" OD! His used stones would not reach the diameter he needed, so he bought another fresh set to get all the way to 3.125".
96 GTS - exhaust, brake and extensive handling mods.
It's been a month waiting for valve guide material to be identified, sourced and machined from malleable iron. My guy competes with Prefix and didn't want to call them for help. Now it's in and the head prep is underway.
My builder also has been concerned about oil return to the stock pan, so I copied "deyan's" (VOA site) top plate config from his former VRL car and we feel better about oil return and control. He got the short block all finished today!
Some movement on the heads! 2.02/1.60 Manleys, a little short side and bowl work, then chamber deburr, intake match, valve geometry check and install in the car. I can hardly wait, but Race engines go to front of the line...
Finally got the right valve locks to give the right tip extension and installed spring height. Sampson Race Engines really wanted to do some heavy port magic, but I'm keeping it simple. These springs are Beehives in PSI's 1500 catalog. Single spring setup for my Gen3 1.7 rockers, but they are the best stuff out there and are the same material they use in the T/A motors.
