Chuck 98 RT10 Love the updates Dean.

GTS Dean 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.

GTS Dean 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...

GTS Dean Completed short block. Missing oil sender and balancer. There's a reason some people put a strut on their Viper engine stands. The CG is wayy out there!

Chuck 98 RT10 Enjoying the updates Dean. Keep 'em coming.

GTS Dean 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!

It may actually happen this month!!!

GTS Dean 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".

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.

Oh - you mean all of his broken Photobucket links that he refused to update, or actually make ATTACHMENTS of, instead of links?

He said to get the motor broken in well, then put it on the dyno for a couple of pulls. Once that's done, I'll plug in my DRB-III and provide the Adaptive block values, along with the dyno chart for him to evaluate before doing the bench update on a spare JTEC I have.

In the meantime, I've been VERY busy for 2 weeks with suspension and body panel adjustments. Suspension is done, the doors and hood are done; fascia and headlights are still an agonizing, iterative process.

My hat is off to you SIR!

I have so much PTSD working on alignments, I will literally drive at the pace just over "crawl" on shitty roads, and yes, I basically stop traffic when crossing railroad tracks.

I know that you already know, but it's worth bringing up here: all of my most effective adjustments to the hood/headlight/door/hood-to-rocker(sill) was done AT the core support.

Good luck Dean. YOU'RE definitely the one for the job!

GTS Dean There was a group that had it booked last weekend but I don't know the name. A couple of friends were running, so I'll see what I can find out. I think Chin is there this weekend.

Dean, who do you book HPDE days with at COTA? I've seen a couple of CHIN listings for there, but was wondering if there's another track event organizer I'm missing

(Just Track It doesn't go there and that's mainly who I register with)
June 18th, 2020 05:00 PM
Chuck 98 RT10 I have the same mindset.
June 18th, 2020 03:01 PM
GTS Dean Yes - a port match and light pocket/guide work. I'm not looking for big flow numbers since I'm keeping the 708 cam, just smoother flow.
June 18th, 2020 02:08 PM
Chuck 98 RT10 Are you gonna do any light porting on those heads?

Mmmmmmmm COTA. I really had a kick ass time going and watching the formula one races there. One of the best memories of my life. I couldn't imagine taking my car on that track!

GTS Dean The block is just about ready to bolt together now. The heads are disassembled and my bent valves are here for display. The #9 Intake is bent the worst of all, and that cracked the valve guide. These valves have unusually long stems, and Dodge is not stocking them any longer. I'm going with a new set of slightly oversized Manleys that will still fit the stock seats. My builder checked one OEM spring set and he said he couldn't believe how light they were on seat pressure. I'm going to use new bee hives for the Gen 3 rockers.
