i have a 350 i checked the casting number and it is an 87+ 350. it has the 305/350 heads center bolt valve covers but does not have roller lifters it has the standard flat lifters.

 

I'm thinking truck engine / block. Anyone else?

 

Yup, That's prolly what it is. Does the engine have the standoffs in the lifter valley tapped for the spider? If not tapped, are they even there?

i dont understand your question. if you mean could a roller lifter setup have been there at one point that id have to answer no.

 

I'd have to dig out some old Hot Rod's, but I think some of the truck blocks had the extended lifter bores and other provisions for a roller cam - they just didnt finish the machine work. That way they didn't have to engineer two blocks for '87.

 

cool thanks

 

What's the casting # (block and heads)
