Always good to see someone else from the Pacific NorthWET!

Nutter does some engines and dyno's them over at Jim Preston's some times... and he used to build Preston's drag motors...

Where are you in the PNW??

Lol... nothing like 4 straight months of gray sky's and drizzle. I'm in Vancouver. I run my car at PIR. Might have to check out some tracks up north sometime.
Nutter is a great guy to work with, he's told me a few stories about his drag racing days... do you know him?

some of your posts indicate the engine is very streetable. I was wondering if you could comment on a few things -

what is your idle vacuum and rpm ?

When you do a cold start at < 45 degrees out, is it the kind of OEM cold start where you can just drive away right away with no issues or is it still a bit hot roddy where you like to let it warm up a minute or two or at least have to drive a bit gingerly at first ? By gingerly I just mean in my rig on a cold start it will drive more or less ok, but it doesn't like a bunch of quick throttle and it will still be a bit balky at low rpms and small throttle inputs until it warms up.

The vacuum level measures just over 10 in Hg at the 1,000 rpm idle speed. I took the vacuum reading off the port on the back of the TB.

After the engine starts I usually let the car run for about 30 seconds before I touch the gas. At that point the car is ready to go. Before the engine gets warmed up I just roll on the throttle gradually. It takes a bit before you can hit it hard. The engine does not balk or stumble though. It has a crisp smooth tip in off idle even when cold. I do a lot of driving on the street and in traffic... no problem... easy to drive, seriously.

This is my first LS engine project with computer control. I am amazed how well the engine starts up, runs, and idles, and returns to idle. The idle always returns to exactly 1,000 rpm at the stop lights (no surging). I have driven the engine in 100 F degree temps this past August and now in the 30's F with no change in the tune. So much better than a carb set up.




Here is a link to an under hood; cold start; idle video. The temp was in the upper 30's F when I did the video. The idle speed was 1,000 rpm.

When I did the dry sump oil system I had to figure out where to mount the remote oil filter. I ended up fabricating a custom bracket that mounted onto the stock hood hinge. The bracket uses the factory fasteners for mounting. This worked good... I didn't have to drill any holes on the inner fender or fire wall. The filter cleared the stock heating duct on the fire wall. I bought the billet aluminum black annodized oil filter mount from Moroso.

I plumbed in a pressure switch into the oil filter mount. The switch turns on if the oil pressure drops to 18 psi. I mounted a large red light in the car so that if I ever have an oil pressure issue the light turns on. This way I don't have to monitor the oil pressure gauge.

Also, I installed an AEM wide band gauge to get real time feedback on the air fuel ratio.




Yea that is the original AM Delco radio and factory Tach. Some day I might go FM.....




I replaced the factory cluster gauges with autometer (originals didn't have any numbers)

I believe what you say about the engine being very driveable but a 10" idle at 1000 rpms falls pretty far outside my desires. I currently pull 16" at 850 rpms and I still find the thing a bit rumpity (mine is a big windsor). But I'm getting older and my daily is a '92 Cadillac so anything feels rumpity to me.

I was curious as I have a driveability issue pulling 4th/5th gear below 2000 rpms and was wondering if my Super Victor intake was part of the issue, so I was interestedin how it drove for you, sounds like it drives pretty good.

I only know of him. Never actually met him

I went to Schumway a few years back. Like 46 years ago! Lol
Yeah I'm still dumb.

When I was 16 and 17 I worked at PIR. We ran Wednesday night 1/8th mile. Back then we called it grudge racing. And of course worked the bigger events as well. Then I traveled with McCulloch and Whipple in '70 and '71
