Looking for a web site or information on inline 6 block and head casting numbers for 54-62. A friend said I could dig through his stash of 6 cylinder stuff to build a motor for my 51 project. Thanks' Don
Any 235 from 55-62 is a good one...came with both solid lifters and hydraulics. Look for a head with the last three numbers 848...that's the best one. Somebody like *****6 can give you more info on what to look for... Brian
yes the 848 head is dope and get the mallory dual point dst. we put one in my bros 54 and it made a HUGE difference in responce and power ....
ummmmm lil question here where is the casting number for these 6's, i have a feeling its the number behind distributer, but not 100% sure
Hey, choptop30, I got your PM, but I'll answer over here. First, I was going to send you over to the Inliners site to look at their casting numbers list. Print it and take it with you while you're looking through this stuff. Inliners also has an article about the 261" in their Tech Tips, but I had trouble getting that page to come up. Go look @ http://www.stovebolt.com/techtips/ for some more info on these engines. The number on the pad behind the distributor is the SERIAL #, not the CASTING # (big diff). Someone had just posted a new tip on the Stovebolt page on I.D.ing a 235 or 261 engine by the serial #. Also, read the short article about the 261" they have. Learned something new myself; from '58 on, the 261" had a screw-on oil filter. This was a first for the Chevy and GMC sixes. As Kustm52 pointed out, any 235 from 55-62 is a good one, same goes for the 261, which only came with solid lifters. The head with the casting number ending with 848 is the best one to use with either block; it has the smallest combustion chamber. I mention the 261 because it is no more expensive to build than a 235. With a mild overbore, you can have a 270" six, which is a 15% increase in cubes for no real extra effort. The only thing you give up is hydraulic lifters. Most of the later 261's had a head with the casting number ending with 850. If you think you have a 261, look in front of the starter for two small raised lines (Army Captain's bars) on the p***enger side. Also look just above the oil pan rail on the driver's side for two oil lines or pipe plugs, one above the other. 261's were set up to install a full-flow oil filter, as an alternative to the ****py byp*** filters that were in common use. If you go with a 235, read the Inliner's Tech Tip on converting your block to full-flow BEFORE it goes to the machine shop. Your engine will thank you. Oh, yeah, while you're looking around, try and get one of the late truck bell housings that have two flat, angled mounting pads on the back side. That way, your engine can be supported at the rear, and will make for easier clutch and trans swaps/repairs. Good luck, and post back on what you find. Later, *****6
I have a 53' Chevy car with a 235 inline 6 and I need the location for the block casting number. Thanks, Jimmy B
The casting number location is behind the p***enger side engine mount. You can't see it until it's removed from the engine block. It is possible to decode the engine with the serial number which is stamped into the machined pad to the rear of the distributer. Sent via Western Union Express
