Nice, what colors, any mods at all, last 4 of the VIN? Any pics available? Everyone will agree that we like pics. Welcome to the brotherhood.

I know it goes against what others have said, but I have had great luck using Gunk on the motor. Stand by with water and rags. A pressure washer has worked well and I have even done this at a car wash several times. I spray the Gunk on liberally, let it soak for just a couple minutes and then spray it off, keeping it away from openings that will lead to the engine valley as much as possible. I wipe the motor down quickly and start it right away. Never had a problem. You might check the drain, a little tube by the lower bellhousing area, blow air, or run a coat hanger up through it to make sure it's clear. (Do this anyway)

Concur, Corey is the "man" in your area, wish he was a close to me as to you. I rode in a 415 ci he built, WOW.

Concur, stock chip in 90-91 caused high idle.

Pics of your '69 would be nice too.

Hope my comments help, others have/will post up.

Thanks for all the advice.

The injectors are original as they are black with a stainless steel clips. I will need to search here for instructions and parts best used. Do the spark plugs and wires need to be changed out at the same time. If yes what spark plugs are best?

My car's VIN last four digits are 1964.

I was hoping for a shop a little closer that San Antonio. But it is what it is.

I'm aware it's a haul, my wife is from Bourne (sp) and has family in huston, but going there will be beyond worth it. you're going to need new injectors soon.

Would you change out the injectors yourself or pay the bucks and have it done?

Did mine myself with advice from the brotherhood. Not hard to do

I have spoken with Rick a couple of times in the past. Hope I can convince him to be a mentor when the arm heals as the plenum is coming off, change out injectors, check the vacuum, check the coils, ect.

Here is my material and tool list, am I missing any thing?

I will use Viton over Buna here is my short list of the items needed to replace the injectors.
