This is a Chevelle engine block #3814660 head #3917290 date B-2-8 both heads TO205EI 250hp.Did the Chevelle 250hp use the same heads as the 210 2 barrell engine?If so I just scored a complete intake to oil pan std. bore std. crank engine.

Chad,

The 1968 Camaro 327/210 and the 1968 Chevelle 327/250 both used the same head, 3917293. I'm assuming you made a typo with the 3917290 number.

It also appears that you made a typo with the block. It should be 3914660, not 3814660. Correct? If so, it's a 1968 327 used in the low performance passenger cars, Chevelle's, Nova's, Camaro's and Corvette's.
