Orange overspray on SB's
 

In preparation for next years Nova Nationals, I have a list of 'to-do's for my Yenko - some of which is new knowledge since I completed my resto almost 5 years ago.

Was there ever any conclusion as to the existence of orange overspray on the top end of '69/'70 Z28 engines? The first I had ever seen was the 6k mile LT1 pics, are there any more engines found like that one? Any pics? I'm leaning towards duplicating that slight amount of overspray from the 6k mile engine, knowing that I will most likely get dinged during judging. But, that's ok with me, they ding me for stuff that I know is right, and that's just the way it goes - but I'd love to have more than one example in my back pocket for that discussion.

Any help?

Where is the thread with all those pics of the 6000 mile LT-1 motor? I remember looking at the thread a long time ago, but i didnt save the pics... They were some nice reference shots...

Marlin here are some survivor 69 Z shots from my gallery. Kenny's shows traces of it like in your photo. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif With such a small amount I never bothered to even reproduce it. Seems to be mainly in front of the intake really. Never have seen any on valve covers...

Excellent pics Darren, thx. Schoneye recalls a small amount of o/spray on his deuce intake. This gives me more proof, especially on the thermostat housing.

Here is the link to Greg Robert's site with the low mile LT1 pics:

Marlin keep in touch on this one. I am very interested in how it turns out for you.. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

I would assume that the LT-1 did not have a significant amount of overspray on the intake manifold solely because the valve covers were not painted. I would see a nice overspray line on the intake of a car with a painted orange valve covers like the '65 L-78 or L-72 in our Corvette. But motors like the LT-1, L-79, DZ302 should not have much overspray. The areas like you mentioned, on the front and rear of the intake (north and south ends) but not on the sides.

Great pictures.

The mask used on non-painted valve covers and Al intakes engines covered the complete top of engine.
So there could be minor overspray at the front and rear, depending on the mask and the painter. But as Mosport says, there shouldn't be any on the intake sides. I've seen several L78's painted on the intake sides, they are wrong. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Marlin, This is a subject I've been looking into for quite a while. I live near Flint and know a guy that painted these engines for thirty years (now retired) he went into detail about what was on the engine at the time of painting. The only mask was on the valve covers, the intake got hit front and rear and at the end of the line there was a guy with siver pait and a brush touching up the intakes. I didn't touch my engine at all and have silver paint front and rear and several intake bolts.

Wow...this is why this site is way too cool...

Thanks Jack for the great information! https://www.yenko.net/ubbthreads/imag...ns/worship.gif

Get out!! That's very cool info, never knew the sequence on the SB paint method - much less that they would silver up the overspray! Thx https://www.yenko.net/ubbthreads/imag...iggthumpup.gif
