ToplessZ Posted February 6, 2003 Share Posted February 6, 2003 Hello to try and answer your question. The 010 blocks refers to earlier casting blocks that had a higher nickel content in them making them slightly more durable. Is it worth dropping in your zx well we'd all love for ya to drop and V8 in there. Pics Required. Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted February 6, 2003 Share Posted February 6, 2003 More specifically, it is the 3970010 block I believe. This site has the year cross ref: http://www.mortec.com/castnum.htm Quote Link to comment Share on other sites More sharing options...

Guest Thurem Posted February 7, 2003 Share Posted February 7, 2003 So to continue the history lesson. Anybody have some background on a 3932386 4 bolt block, supposed to be 350 but was also used in 302 Z28's. Anybody with background info etc..

Mike C Posted February 7, 2003 Share Posted February 7, 2003 Large journal block for 302/327/350 1969 only, can be two or four bolt. Use same numbers as above to see if casting is high nickel or standard. Don't know of any durability problems with it. It and the 3970010 fit all of the same applications. The 010 block soldiered on until 1980. Quote Link to comment Share on other sites More sharing options...
Mike C Posted February 7, 2003 Share Posted February 7, 2003 010 is the last 3 digits of the casting number. There are another occurrence of three digit numbers behind the flywheel or timing cover. Two occurrences of 010 010 is a 1% tin 1% nickel block. 010 020 means 1% tin 2% nickel. This is the "high nickel" block. 3970010 was available either high nickel or regular, either two bolt main or four, so you have to pull the pan to verify bolts and look behind front or back to verify nickel content. The high nickel blocks are more wear resistant than the standard block, but both will work fine. Quote Link to comment Share on other sites More sharing options...
jt1 Posted February 7, 2003 Share Posted February 7, 2003 The 3970010 is a desirable high nickel block as stated above. Most, but not all, are 4 bolt main, be sure to check. Zfan, what do you mean by two piece? Two piece rear main seal? John Quote Link to comment Share on other sites More sharing options...
Corzette Posted February 7, 2003 Share Posted February 7, 2003 Hey I have the 3970010 block 4 bolt .o4o over. Nice to know. Its 1975 block. CZ Quote Link to comment Share on other sites More sharing options...
280Zen Posted February 12, 2003 Author Share Posted February 12, 2003 Thanks, yes its a 4 bolt, high nickle content. Bummer the wife snatched it for $500 to put in her 84 camaro shes rebuilding. Pulled the heads off last night and found out its punched out 30 over. Also found out is was previously used in a boat! Quote Link to comment Share on other sites More sharing options...
280Zen Posted February 12, 2003 Author Share Posted February 12, 2003 Now, for the next couple questions to this! How much Torque, HP will this engine put out in that camaro? Giving stock pistons, crankshaft, cam, carbs, exhaust And what will I need to do to my 280zx coupe, F54 block, P90 head to take her in a quarter mile run. Nope not going to do a V8 conversion!

Mike C Posted February 12, 2003 Share Posted February 12, 2003 There is no way that question can be answered just based on block casting number. As you can see, it was used in 302 (factory rated at 290 gross hp, but most were at least 290 NET hp) 327 rated at 210 hp, and 350ci motors. The 350 was rated at 250, 300, and 360 (370 in the 'vette) in 1970. In 71 the ratings were reduced to reflect lowered compression and in 72 the ratings were flywheel net (with full exhaust and all accessories but still measured-as now- at the flywheel.) "Stock" is relative as compression varied from as little as 8:1 to as much as 11:1. Cylinder heads, intake manifolds, camshafts all have significant variations. Assuming you have a truck motor with iron heads, cast iron intake, and 8.5:1 compression (this is a reasonable assumption I think) You are looking at about 240 gross hp, the same as a new GM targetmaster crate motor. Should put out high 100's at the wheels (180-190, maybe as high as 210) Quote Link to comment Share on other sites More sharing options...
