GraniteGuy88 Posted January 25, 2021 Author Share Posted January 25, 2021 This is right behind the alternator on the block/small cliff. The first few letters seem pretty legible but i cant find them anywhere on a search. I will look on driverside, right of the fan tomorrow morning. As for a carb, I do not have one available. Dont exactly like the fact the previous owner like to jerry-rig things.lol. they seem pretty pricy. Thing a rebuild kit and cleaning may fix it? If they were driving it like that wonder what else is rigged in order to make that work!? Quote Link to comment Share on other sites More sharing options...

No. You're missing important parts like the secondary vacuum actuator and associated linkage. Who knows how they have the secondary's rigged to work. Also, is it possible that engine stamping it a TRC? If so, it may be a 1973, 1977 or 1980 truck 454 engine from a quick search. http://chevellestuff.net/qd/engine/bb5_codes_tbg_yz.htm http://www.1968ss.com/BBCsuffix.asp Quote Link to comment Share on other sites More sharing options...

It was dark so i did a quick video to check out some of the things mentioned. I found this on the block behind the alternator. Looks like T4121TR6 best i can see it atm. Cant find a internet match though. I also took a few of the Transmission. Kinda hard to see under there. I hope you guys dont mind me posting all the pics. Its just exciting. As for what I want from the car... Well im a Cruiser. Not really worried about speed. I love the Power of what I consider a true American Muscle Car. When that thing fired up... Man.. I had to have it. Im a family man with wife and kids. This is my baby. I want it to be just a Sweet Car to take out now n again. Ive always wanted like a late 60s Impala.

MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 Yes, I am seeing the missing parts from the carb. A rebuild would be moot. Best bet is another carb. I don't know for sure but what I see of the engine, I believe it is a 454 from a truck. Probably mid 80s to 89 ish. There appears to be only one paint job on it and it's black. The truck engines of this era were black. Just a guess. Quote Link to comment Share on other sites More sharing options...
GraniteGuy88 Posted January 25, 2021 Author Share Posted January 25, 2021 Thanks Rob. I can post more random engine pics if it may help. It was just weird that I cant find that sequence on any block sites. It all seems fairly clean too. The previous owner (half crazy lil ol lady) had mentioned when we first began to talk that they paid 5k in the engine.... Then proceeded to take considerably less for the whole car.

MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 Just because it MAY be originally from a truck doesn't make it less desirable. It's a big block. The 496 in my 70 SS started life as 1988 2500 4x4 suburban engine. Quote Link to comment Share on other sites More sharing options...
GraniteGuy88 Posted January 25, 2021 Author Share Posted January 25, 2021 Yeah i tried cleaning the pic up a little. Just a booger not really knowing what it is. Ive been snapping scrn shots from a short video. Also ran across this which at first look maybe looks like numbers i didnt catch on the front of the block but it may be nothing. Either way Im still siked. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 If possible, can you get a pic of the back of the block, on the driver's side where the trans bolts up. The casting numbers should be there and tell you for sure the cubic inch the engine started life as. If the former owner had it rebuilt before installing it into your car, they could have easily spent 5k on it. You should be siked, you have good bones to start with.

GraniteGuy88 Posted January 25, 2021 Author Share Posted January 25, 2021 Yay! Update. Ive located the engine block number on backside/driverside near bellhousing. There were also some other numbers near the same area. Also on the passenger side behind the block i found what im guessin might be a mnfg date? Found out I have some loose and missing bellhousing bolts. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 Ok, what you have there by the casting numbers is a 1972 402. K 10 72 is the date code and 3999289 in this case is a 402. In later years the 3999289 block was also used for the 454. Glad and sorry you found more work with the loose and missing trans bolts. But better you found them now instead of the trans falling out.

GraniteGuy88 Posted January 25, 2021 Author Share Posted January 25, 2021 Im just happy to have a good idea on what it is now. What is it that still makes it a 402. I cant really find much more than this. Would it still be considered a original-ish motor to the car? Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 Jft69z brought it to my attention and also the chart you posted, that I may be incorrect. In 72 the 3999289 block was also being used for 454s. The chart I used as reference said that didn't start till 73. I now believe that to be incorrect. Check the balancer. 454s had a big balancer on them as opposed to the 402s smaller balancer. Diameter wise. Quote Link to comment Share on other sites More sharing options...

That, coupled with the what Tom & I believe to be a TRC stamping still leads me to believe it's a '73 (or later) truck 454. The casting date would still be in the range for that possibility. Also, like Tom says, check the balancer, it should be for an externally balanced 454. Same with the trans flex plate if you pop the torque converter inspection cover off and investigate for balance weights on the flexplate.

GraniteGuy88 Posted January 25, 2021 Author Share Posted January 25, 2021 I will get measurements when i get home. The more i look at it i think the original owner might have had engine work done and was in the process of getting it all back together. So in you guys opinions, would you say its a a good setup. Far as trans/motor/car setup? Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted January 25, 2021 Share Posted January 25, 2021 If I'm not mistaken a julian date code of 72 makes a 289 block a 454. I have all three years of 402s and they are all 854s 1 Quote Link to comment Share on other sites More sharing options...

Sure, as long as you get the carb replaced and do a thorough inspection to see nothing else was rigged up like the carb. See how it runs, do a full tune up, etc. If it runs good, go with it, you'll have a lot of fun. 1 Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 It is a 454! 72! I did more checking , this time with my eyes opened fully. Everyone that has stated it's a 454 is correct. Sorry for the confusion I caused. 😞 Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted January 25, 2021 Share Posted January 25, 2021 A 454, th400 is a good combo. The 10 bolt may not live too long if you beat it daily but otherwise should be ok for now. Since we now know it's a 454, I recommend a 750-800cfm carb. The factory 4bbl Rochester was in that range. 1 Quote Link to comment Share on other sites More sharing options...
1970mcss Posted January 25, 2021 Share Posted January 25, 2021 Like others have said the engine trans combo are excellent. Like MC1of80 suggested put a new Holley on it, double check the fuel lines and see how it runs. Oh and welcome to the club!!!! Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted January 25, 2021 Share Posted January 25, 2021 Do we in fact know it's a th400? With the 10 bolt it could be a th350 unless I missed something along the way which is quite possible lol. Quote Link to comment Share on other sites More sharing options...
