I just got my hands on a genuine DZ302 and man am I excited to build and slap that bad boy in my truck. I'll pull the mercruiser 240 out and put that sucker in and bam high rpm monster. What do yall think?
It needs some cleaning and love but the rust is surface level and it turns freely. It also has an astronomical amount of wheel bearing grease on it. It is a 69 DZ302.
No there are all kinds of urban myths about the 010 block. Some folks swear it's 10% nickel. Not true. The one true thing about it is there were probably more of that casting number built than any other because it was around a long time and was used for all kinds of engines. 302, 307, 327, 350, 2 and 4 bolt. Not sure if it was used for the 262 or 305 V8's like the ones in the Monza's.Don't quote me but I always thought the 010 designated a 4 bolt main block also. ?
