Can someone help me identify what year and model Chevy it came out of base on the following: engine # F0 309TA and block casting #3677178? How hard a swap would it be for my 1952 2-ton dump truck with a 4-speed tranny with the 235 currently in there? Got the 250 for $70, just had to bring it home and then figure it out! | | |

The year range for that block depends the the source of info, and goes from '65 to '78. I think '66-'72 for the 250 is about right.
This engine was originally built on March 9 (0309)at the Flint (F) plant. The TA suffix is for the standard 250 w/ manual trans., 1 bbl. carb., 155 hp, and was used in the '66-'68 C10-20 and K10-20 trucks. The casting date code on the block would pinpoint the exact year.

I'm running a 250/6 in my 52 3100, with the stock 4-spd tranny, and rear-end, that works great. I didn't verify for sure, but it seems that the information your providing is awful close to what I remember mine being.
It came out of an early 70's model truck or van.
You will need to fabricate some side motor mounts, if you want to put it in your truck, as the original 216/235 was a front mounted engine.
It will run circles around the 216 that's in my 46. | | |

I cut the motor mount perches out of a donor truck and cut them down to fit. Everything else just bolted up. Accelerator linkage just took time to devise. Once I figured it out it was a no brainer.

I have a 53 with the 216. I've thinking about swapping the 216 for a 250. Can I really stay with all of my stock running gear? And still be reliable? lazy

I've thought about someday changing the rear gears, but it will run down the road between 55-60 pretty comfortable, (not overly reving the engine) like it is, so I'm not sure it's worth the extra $ for me.
The original 4-speed tranny is great, runs down the road like a champ, and would pull a house, if I needed it to. Clutch/pressure plates, and bearings are still readily available, and inexpensive.
The rear end, other than the gearing isn't a problem.
For the most part, I use both my trucks for weekend pleasure, so neither really sees alot of highway use. The 250-six sounds good, runs good, and is different than everyone's SBC V-8.
I've had 3 different vehicles with 250's. Never had a serious problem with any of them, and never put any of them "down" before logging 175-180K miles.
Good Luck | | |
