i just got a 49 ford shoe box... it has a small block chevy in it. i got a picture of the head casting mark. can any one tell me what it is.. i think its a 283 but not sure
Going to need more than a picture of the head casting design. Look,if you can get to it on the drivers side rear of engine where tranny and engine meet,there will be a casting no. there that will tell you exactly what you have.Post the no.
Uhm, not sure really, but we used to call them "power pack" heads. We believed they were not high flowing heads but more the stock economy type head. 2 bumps, camel hump. One bump or a triangle, power pack. This was long ago and we were kids so we didn't know much. OK, I googled it.. here is what I found http://wiki.answers.com/Q/How_do_you_identify_283_power_pack_heads the power pack head will have no acc. holes on the face and will have a casting mark shaped like a rectangle with a triangle on it, also know as the pyramid. Further reading show them as 283 heads and have higher compression due to a smaller combustion chamber. I hope that helps and that I am not lying out my butt...
That will only tell you what the heads are from....they could have been swapped. Get the casting number off the back of the block, sort of behind the drivers side head.....
in addition to the casting number and casting date on the back of the block. look for the stamped number sequences on the front of the block deck surface, just in front of the pass side head. Post those numbers/letters, they'll tell us what it is.
it's the pad on the front of the engine block, right bank that gives you the engine build date,engine size,as well as the bellhousing casting number,it's an early block up to '67 when you find the extra hole for the breather canister at the back of the block just behind the intake. no canister under the intake? 68 and later
This web site decodes the block casting numbers http://www.ajgeneral.com/sbc_block_casting_numbers/ There are also numbers stamped in the block surface (passenger side) just to the front of the head. These actually tell what the engine is. This web site may help you from that aspect. http://www.yearone.com/updatedsinglepages/Id_info/gm_engine_id/engineinfo6.html Good luck.
after looking that head casting mark up in my small block interchange manual, my money is on a mid 70's 350
no hole for power steering and Alt pre 1968 it looks like a 68 cc head were the guide plates there when you got the heads or did you put them on
Looks like a right triangle to me, that would make it a.....drum roll please.... "Large chamber (76cc) light weight head" maybe off a 350 but I don't think it's from the '70's, I am thinking earlier. I found this link in an old H.A.M.B. post from 2008 http://www.fastnuf.com/Headguide.html
i found these numbers on the head 3947040. this number on the pass side of the block v1029tck and ccj115303. i cant see the numbers on the back side of the block the way its been set in the car
'040- 64cc 327 head circa 1968. Doesn't mean that's what the block is though. I've got camel humps on mine, that doesn't make it a '64 corvette motor. You need to get to that rear casting number to be sure.
Got that engine code from the front stamp figured out. v1029tck: v=Flint (Engine) 10=October 29=29th Day TCK=1973 307 So it's a 1973 307 with 1968 heads... http://www.nastyz28.com/chevy-engine-code-stampings.php
where are you finding your casting number info for the heads, is mortec no longer around? i found this site, http://outintheshop.com/faq/casting/heads.html they show the heads as 68 to 70 and with 194s or 202s
CCJ would be a 1982 chevy truck engine. C means chevy truck, second C is the model year (numbers in the 70s, letters starting with A in 1980), truck was assembled in Janesville WI. If it were a 1973 truck engine, then it would be C3J.... The suffix TCK could be from 73, or it could be from some other year. Chevy did use the same suffix for way different engines in different years. Without the numbers on the back of the block it's hard to say for sure what it is. I don't have truck suffix numbers from the 80s.
With a 3 letter suffix, it should not have the breather hole back there. 1960s engines had a two letter suffix.
As long as we are here I have a sbc block vin code VOI05KM. The KM doesn't show up in my motors manual. Anyone know what the KM means? I'm calling it a mid 60s' 327.
