For the 396, they made two connecting rod sizes. 3/8ths, and 7/16ths. However, the 427, and the 454 were both considered heavy duty, or high performance only, so, as far as I know, they made only the larger rod size for those two motors.
The rod torque on a Chevy 350 V8 depends on which size rod bolt you have. On the 3/8 rod bolt the torque is 45 ft/lbs On the 11/32 rod bolt the torque is 35 ft/lbs
the big Chevy truck rod is bigger than a passenger car rod.
sorry, the 454 Big Block engine was used in General Motors vehicles. Apparently you have a HOT ROD!!
No it will not.... Just remove the fuel pump push rod and install a block off plate where the fuel pump once was. That's it.
Small block and big block fuel pumps and fuel pump rods are the same on all Chevy V8's up to the mid 1980's when fuel injection and new block designs started on the market. Please note that this does not include special cam motors (roller cams, etc) that do take a different (special) rod.
The L-88, 427, which was the King Kong of Chevy is 69, redlined at 7000rpms. In 70 they introduced the LS-6, and LS-7's, which were aluminum 454's, redlined at 6800. I would say that is about it. Now, keep in mind, these were steel crank, 7/16ths rod, 4 bolt main blocks, forged piston, high compression, and cammed to the gills. NOT stock, by any means.
On the transmission where the shift rod connects. The rod should run through a block or bracket that has a bolt that tightens down on the rod. Loosen the bolt and the rod should slide in the bracket. When you have it in place, tighten the bolt back down. It could also be worn bushings where the rod changes direction. These can just be replaced.
inner main caps 70 ft. lbs, outer main caps 65 ft. connecting rod torques are 45 ft. lbs (caps)
Lack of lubrication.
Stock rod length is 6.135 inches, unless it's a tall deck engine, in which case the rods are .400 longer (6.535), tall deck engines were used in big trucks like dump trucks and were usually 427 cu in, if you're talking about a pickup truck or a car it's most likely a short deck version. Deck height on a short deck big block Chevy is 9.800" from the center line of the crankshaft to the deck, deck height on a tall deck big block Chevy is 10.200" from the center line of the crankshaft to the deck.
Just turn the engine over while you are pushing on the rod with your finger until the rod goes up in the block and starts to come back down then stop, and install fuel pump. Turn engine by hand. Put a ratchet and socket on the balancer bolt in the middle of the bottom pulley. Turn it that way.
