My info came straight from chevrolet, the complete motor was never put on the market unless the history depart. has slipped a gear? Never heard of a car with that equipt, back in the day? chev stated that research was done on types of that motor till the 90's. the add could be what the industry called a teaser, to test the market for aproduct.AS 1970 was the last year for the high H.P. motors. as the ad reads that motor would have way over 700 H.P. Any info about a real ZXL car? Thanks Bob krueger. motion was the seller, not the producer in the ad.

Uhm Bob...

I'll stick to my answer on both the ZLX and the Medium Duty Truck engines.

FWIW II...

Assembly line photo of some &quot;W&quot; engines at the assembly plant....courtesy of LIFE magazine. It shows that Chevy painted most everything including the exhaust manifolds.








From first hand accounts of people who worked in these plants...there was a &quot;mask&quot; of sorts that was haphazardly placed over the aluminum intake area on the big blocks while the engines were sprayed...so over spray did indeed get onto the intake and heater bypass hoses. After all, Chevrolet was in the business of building cars...not restoring them [img]<<GRAEMLIN_URL>>/smile.gif[/img]

Plus, there are many documented examples of low mileage unrestored cars that still have the over spray on these areas!

Pretty neat pic Bruce. Never saw that before.Looks like they only missed hose ends of water pump ,thermostat housing and water pump pulley flange face on these. By pass hose looks to be installed after paint too. Odd.
