8.50 index build

Todd Geisler · 06-11-2022, 10:11 AM

So Thursday was dyno day. Day went pretty well, made 6 pulls and decided to stop. The oxygen sensor on the Dyno Holley wasn't cooperating all that well. Felt we had a solid baseline tuneup saved which was really my goal for the day. Didn't hurt that the engine wound up making 15 more peak HP than before. O2's were still on the rich side (dyno o2, not efi) and the top end rpm limit was still a little low so it's safe to say there's still a little more power to be found down the road.

Engine changes since last time were swapping the too tall SV565 intake for a fully ported old school 2927 Super Victor. The last set of titanium valves gave us nothing but fits and were damaged so they were swapped out for a set of custom stainless valves along with a stronger spring package, new titanium retainers and titanium locks. While doing the intake fitment (cylinder heads have dowel shift) and porting on the manifold, the cylinder head guy found a couple small areas on the heads he wanted to adjust a little so we did. My guess is the additional power was from those small tweaks.

Got home from the dyno at 6:30, quick dinner and back out to the garage. Engine set in place by 9:00. lol

Last evening I didn't do all that much other than cleaning the exhaust port flanges to be able to bolt the headers up.

For those wondering how the Rife sensor mount was gonna work, here it is mounted to the firewall/cowl panel.

Finally something worth sharing on the wiring. The main wiring panel and relay board are wired up. Not complete, but enough to power up and start testing some circuits.

Looks pretty decent for someone who doesn't wire cars for a living. lol Not perfect, but I'm pleased with the results. Have a couple small things I may tweak and try to improve.

Next I gotta do the engine grounds, then I'll start on the coil harness and then the EFI engine harness.

Sunday I was able to finally apply power and test a couple circuits. Was really nice to finally see the car showing some signs of life.

The dial boards have a neat feature where they dim when the parking lights are on so they aren't overly bright at night time.

Back to waiting for some supplies to come in this week.

Next it to finish the engine grounds, then start on the coil harnesses. After that it'll be time to start on the engine EFI harness.

Headers all bolted up.

As much as I procrastinated on building the headers, I am pretty happy with how they turned out. Just don't wanna do another set any time soon. lol

Oxygen sensors and bungs installed.

Throttle rod needed some tweaking to clear the fuel rail. Just a small offset is all that was needed.

Took some time to get the front brakes/calipers shimmed up and then packed the wheel bearings with grease to finish that up.

Work Of Art!
Thanks for taking your time to post all those great pictures of your build.

Thank you. Lots more to come as there is plenty more work yet to be done.
