Eng id help....
Hey guys I have been having some eng ping going on the timing is at 10 deg I have put new wires and plugs. And there is still a ping under load. So after some talk with a buddy of mine we saw that I have no assy holes, My buddy thought the heads mite be 283 power pack heads. Well I Found out the heads are one of two types 3795896....63-65...283......60cc chamber
3795896....62-64...327......60cc chamber. I can't see the block casting numders but I have the front numbers and they are VO4O5TBG Does anyone know what this block is or where I can look to find out? The eng is in my 71 GMC 3/4 4X4 the tag in the glove box say it should be a 4bbl 350 the old guy I bought the truck from told me he had the 4bbl taken off to save on fuel mileage  Thanks for any help guys. Ceth

That looks like a stock valve cover on the passenger side with the Invader 350 decal on it..

Thanks
RaginRat
Thanks for the link thats what I needed. The block is the right one for the 71 GMC So what I think happened was who ever changed out the intake also did the heads. I think the ping comes from not having a good vacuum to the dist. The carb only has one port and thats at the very top of the airhorn. But thats just a thought... I do have a new intake and carb waitting to be installed. But what you guys do about these heads I have on? keep them or get a different set? And Robert when you look it everything looks normal untill you see the lack of holes in the head and the short waterpump. It runs pretty good unless I get on it hard Ceth
