Big Block casting # Hi perf ?

highpockets · #1 04-20-2006, 12:12 AM

Found an old BBC engine very cheap,steamed it off and I see what appears to be some conflicting info.I am hoping you experts could help decipher if I have a good one or just run of the mill BBC. Casting # is 14015445 which if I translate correct is 78-87 454 truck motor 2-4 bolt mains.The weird part is above the oil filter pad is cast hi perf pass. The stamped pad on RF indicates CAF159406,intake is 3931067,cast iron 4bbl. I have not torn it down,but have a friend who wants it for an old truck and I dont want to give it away if its a good one(I do have a 67 RS to play with if it turns out to be a keeper

Any help/leads would be appreciated.

Take the last digit '5' off the block casting and it's a '445' truck block....and the intake appears to be a '69 item? . Is there more info on the 'stamped pad' extended block/deck surface in front of pass side head? .

Yes, the intake manifold is for a 69.
Passenger, 427, (335hp, 390hp)
Chevelle, 396, (L35, L34)
Camaro, 396 (L35, L34)
Nova, 396 (L34)
All with 4bl Quad.

Nope,although there seemed to be more stamped letters/numbers on a little pad,center front below intake rail ? I guess I need to pull a valve cover and oil pan and see what it is ?

And,why would a truck block have the hi perf pass cast above the oil filter ? Are all big blocks like this ?

A lot of bbc stuff says "high perf" run of the mill or not.

Keep in mind these are really passenger car blocks in the light truck series and not the tall 'truck blocks' like 366 etc. . Almost any of the Mk1V stuff is worth putting the grab on but sure getting tough to come by anymore...keep an eye out for 'Burbans/Trucks w/ that little 454 badge in the '73&up grilles. .

I have a 2 bolt 78 454 from a suburban that has hi perf cast on it. Seems they put that on a lot of stuff
