This may be a stupid question, but i can't find out any info on my engines suffix codes. I've tried to just google and yahoo the numbers with no luck. And tried to find a site to help find more about my engine with no luck either.. It is a 400ci sbc , casting number is 3951511, and I found out the basics with this but wan to know more, the suffix numbers/codes on the front of the block are T0414CKP and another set is,12S251618.. thanks for any help in advance!!
LOL thanks I got that from pulling the oil pan! I have found info on the casting numbers just not on the suffix numbers. The info i found on the suffix came back it was an alum. headed 396! NOT! lol thanks for the reply though
Uh looks to be around 72 with 170hp it'll have plenty of torque, but if you're planning on doing anything with this engine these will really mean nothing.
Maybe someone knows the factory torque rating for it- I have Chevrolet manuals but they're either newer or older than '72. The factory ratings started taking a hit in '71 w/the lower CR, etc. required by the fedgov, and how the power ratings were figured changed from gross to net- which made the '72-up engines look 'weaker'.
Bottom line is it really doesn't matter what it HAD, it can make 400-plus ft/lbs w/relative ease.
Thanks alot cole! Maybe I can get the money for a rebuild soon!
