The Stovebolt Site Forums The Shop Area Engine Shop 235 ID Confusion

Sorry to bring up another engine ID question but I thought I knew what I have. But while looking for parts and searching the site to make sure I order the right pushrods I'm getting confused. I have a rebuilt engine and head that was rebuilt several years ago but was never assembled and run. The casting code on the block is 3764476 which, according to Inliners.org , is a 58 - 62 235. There is no number stamped on the flat spot near the distributor which tells me (from previous searches) that it's a replacement block. The tag near the rear of the engine shows CON 3 F 29 4, which, from previous searches, is a date of June 29, 1954. This is where the confusing part comes in. Am I missing something here? (The head, by the way is cast with 3836848 and a tag with CON 9 G 5 7 (July 9, 1957?). For push rods, the master parts catalog shows 10 3/4 inches and 11 13/32 or 11 15/32 (the numbers are blurry) for the 235 (shorter: 53 -55; longer: 56 - 57). Looking at vendors, push rod sizes include 11.4740 (which converts to a touch over 11 15/32), 10.919 (which is a bit bigger than 10 3/4), 11 1/4 (for 55 - 62 235, 261 solid lifter), 10 9/16 (for 54 - 62 solid lifter). A lot of choices out there. Is there a master parts catalogue for 58 and later? The block I have has side motor mounts attached but the timing plate is drilled for a front mount. It came with a clutch etc. in the bell housing. Do I have a '54 or a 58 - 62 engine? Any insight into this would be greatly appreciated. Thanks in advance.

3764476 = 1956-1962 car 235 (probably with hydraulic lifters, mechanical lifters also work in it)

F 29 4 = June 29th 1964 (replacement engine?)

Side motor mounts provides more evidence that it is not a 1954 (did car blocks in 1954 have side motor mounts?).

A replacement block could have been put together with any rocker-arm assembly (and matching push rods).

Have you considered MEASURING the distance between the top of the lifters and the rocker arm adjusters and buying the appropriate length pushrods?

That idea did come to me, Jerry, but after I posted.

Here are a few pics of a lifter from the above mentioned engine. I'm assuming it is a solid lifter (This is the first time I've gotten this deep into an engine)Lifter side view. Lifter top view. Lifter bottom view.

It appears to be a solid lifter- - - -a hydraulic would have a spring clip holding the movable plunger into the top of the main body and it would slowly compress if a steady pressure was put on the pushrod seat for a couple of minutes with oil seeping out of the lifter as the plunger drops. Turn the engine until one of the lifters drops to its lowest position and measure the distance from the pushrod seat to the adjusting bolt ball and you'll be within 1/8" or less of the necessary pushrod length for the combination of parts you have. The travel of the adjuster thread will give you a bit of leeway on the length.
