Engine and trans are in. Ready for final wiring, loaded up and taken back to my friend Taylor's shop to finalize all the loose ends that couldn't be done before the engine was dropped in.

Wiring should be done today, then the laundry list of final details can be handled. Still need drive shaft, shifter cable, radiator hoses, simple stuff.

The car looks great.
I see that you're running a Port-O-Sonic intake. I've run them with pretty good results as well.
Noticed the weld built up on the intake runner near the valve cover rail. Is there a modification you do that necessitates this build up?

This is an intake that was ported and I believe the top of the intake runner gets a little thin in that area so it was built up. We intend on putting a 2x4 tunnel wedge intake on this car, but for getting the car alive we have a 1x4 carb that has already run with this engine on the dyno. We're using this intake for now to give ourselves less variables starting out.

Looking good!

Thanks Bob. I was hoping to have this on the track much sooner, but same as all of our projects, it snowballed. You'll have to see it when we have it running, you'll probably be one of the few that can notice all of the work that's gone into it.

Speaking of Bandimere the new track they are supposed to be building any word on when and where it’s gonna be done.

Funny enough, I'm living in Tulsa right now, I was sent down here for a project. SO, once the car is running I'm hoping to have my dad/uncle trailer it down here and we can sort the car out here. I've been to the track already to check it out, it's a pretty easygoing place. Seems like a good spot to shake the car down.

As far as Bandimere track rumors go.... I've heard their proposed location is Hudson, CO, which happens to be about 15 mins from my house. So I'm ecstatic about the track change if it truly gets moved to Hudson.

Hey Mike. The car is back from wiring, we're down to a manageable checklist of things to check off before its running. I was home from Tulsa last month and tried to pick at some things, I got stuck with the water pump inlet fitting. My fitting hits the ear on the front cover for the fuel pump. I've been pestering the family from down here to keep plugging away at it, I don't think they have touched it.

I did get to check out an NHRA divisional race this weekend at Tulsa Raceway Park. No FE's in stock or super stock  :(

Yeah, I had to get a smaller diameter fitting because of the same problem. Then you have to find a hose that works with the smaller diameter. I think I have a part number of the hose I used somewhere if you need it.
Did you repair the heads? Or going with your new production ones after they’re finished?

Mike, if that water pump is a CVR pump with my adapters, the long water pump inlet fitting will hit the fuel pump ear on the timing cover.  You either need the short water pump inlet fitting, or you need one of my 14002 timing covers, which are designed for use with electric fuel pumps and have the fuel pump boss on the timing cover deleted.

Hi Jay, I already have the hoses made up, but my mistake was mocking them up without the front cover on the mock-up block. I used this fitting:

https://www.cvrproducts.com/product/16an-long-black/

I started with the short style fitting, but the AN female fitting hits the pump body as you tighten it. That's why I went for the long fitting. Turns out a medium length fitting would be about right.

Instead of remaking the hoses, I think I'm going to cut that ear off a spare front cover and weld the hole shut. Not too big of a setback. Just a bit of time to get the damper back off and the water pump off.

This engine just has a set of ported edelbrocks on it. The goal is to build something pretty serious with our MR heads and run that. And in the future maybe something even more serious with the TP heads.

I see, didn't realize you were using AN fittings.  The one at the link below will work, but it's for a regular rubber hose.  Cutting the ear off the timing cover, or using one of my 14002 covers, is the right solution for using AN line - Jay
