Ahhhh-yep That looks about right.

Eye candy to be sure Rob. Did you polish, paint, or powder coat the upper radiator hose fitting? It looks great.

looks great Rob. can't wait for the close up looks next month. nice find on the tps and other potential gremlins. any numbers from your ohm readings would be helpful and most appreciated

Each plug wire should be about 4Kohms, with 3K of that being the plug boot/connector and 1K being the wire and its connector at the distributor. If you get infinite resistance on one wire, separate them at the plug boot (the sleeve pulls back and then the boot unscrews) and measure each one separately to narrow down the problem. Where one gets the replacement threaded brass crimp ends, I have no idea. Greg has them.

On the TPS, I got lazy and didn't test either of my used TPS's before I got to Greg's. I should know better given that I have posted on testing before: https://rennlist.com/forums/928-foru...questions.html

In any case, 1 used TPS didn't click at all, and the other, while making a click, had anywhere between 3 and 10 ohms at idle, varying all over the place. I hadn't tested either. Greg looked at me and said, 'the only 2 important things in an engine are connecting rods and throttle switches...."

The new one drops to 0.2 ohms immediately off idle, every time.

re: no spacers,
I'll bet anything that after those pics were taken for the internet viewing folks
that half of those parts came off and the Skunk Werks Parts went on

Spacers are in hand but will eventually go on at some point during tuning and dynoing. I want to add a data point to the spacer question. There's no obvious special sauce in these pics.

most of the special sauce is under the covers for sure...

I'm getting a few upgrades to my inner workings there now, but nothing like all the extra porting work you had done. should be interesting to see the diff.

I think we found about 28 ft lbs tq and a few more ponies or so at the rear wheel w/the spacers, but we were making so many changes that it's hard to say for sure what did what (ie blackbird, larger headers, xpipe mods, sharktuning, bigger injectors, etc).

Devek swore by them, and they built some pretty mean motors over the years. others swear at them whenever they have to access anything underneath them, lol.

sure looks purdy

Devek used to tell me that anything under about 425rwhp and it wasn't worth it, and I think mr speak used to say the super maf was designed for blown cars that move a LOT more air than the NA stuff does.

most of the street strokers I've seen are around 360-400rwhp or so, and around 400-460 ftlbs tq.

I will be willing to bet there is a lot of little things that add up to a whole lot in that motor.
