CELEBRATING 20 YEARS!

I just got an engine that was previously rebuilt and driven for a short time due to a bad trans. 350 engine 14010207 casting was told it is a 4 bolt and with a cam. Engine has been sitting in a garage for 5+ years. I will replace valve cover gaskets, oil pan gasket and replace intake with a stock 86ss one. Manifolds will be changed to edelbrock headers. Will probably also swap over my stock 86 dizzy too. Planing to keep stock ccc components on it. I am planning on replacing engine and leaving trans in the car. Looking for some general guidance. Is there anything else I should replace since engine is out?

As for engine wise sounds like u got it covered. Since its out toss on a new timing chain cover gasket, check the timing chain also. Check balancer if it comes with one. Good time to change out motor mounts too. Ya know, just check everything over.

Somebody correct me if I'm wrong... Agreed you seem to have it covered so I'm going to try field out some gotchas. '86 was kinda the cross year between 2 piece rear main seals (-'85) and 1 piece ('86-) but also retained perimeter valve covers and early style intake w all bolt holes at the same angle. With that said, the flexplate between 2 piece vs 1 piece is different so if the 350 didn't come with one the '86 from your 305 will not work. I would inspect the condition of the frost plugs and change any that looks questionable especially the inaccessible once the transmission is bolted on. If your 350 came with perimeter bolt valve covers then safe to say your '86 intake will work. Center bolt would dictate '87- intake.

If you don't know what cam is in it, I'd suggest pulling the top timing chain gear and checking it. If you "need" to change it, this would be the time.

Engine still has the trans attached and most items still attached even some ccc harness. It does have the perimeter bolts on the valve covers. I was told 4 bolt main I looked at the casting numbers and it could be a 2 bolt main depending on what it came out off originally. I am looking to get a borescope to look inside just to make sure it’s all clean and good. The only other thing is the dizzy any tips on getting it back on the correct time. Thanks

Get piston #1 at DTC, then mount the distributor pointing at cylinder 1. Hook up timing light and adjust as needed when engine runnin.

You are using the transmission that is on the 350? What trans is it?

Might be hard to find these days, will run without it, but might try to find a different chip for the ECM to give it a bit more spunk.

That is an 80 to 85 engine according to the casting number and takes the earlier flexplate, use if over it it's in good shape and good luck with your swap!!

It’s a 700r4. I was told it was not shifting right. Not sure if it’s the wrong tv cable/adjustment or an actual issue with the trans. I will be using my 200r4 from my 86ss.

I'm sure you are aware, but make SURE the TV cable is adjusted properly before you try driving it after the swap. Sounds like you are keeping the car's CCC and installing onto the new long block? If so, you should be good for electronics as well as TV bracket geometry. If you are talking about using the engine's CCC rather than the car's system, I think you may have issues that need to be fully fleshed out before you get too far into it.

If you're keeping the CCC you're gonna want to switch to a 350 knock sensor, ESC & 350 PROM from group member bitflipper.

I remember reading about the knock sensor. So I would also need a different prom for the 350? Currently running an 87 SS computer. But do have the 86 as well.

The ZZ4/ L69 hybrid PROM that bitflipper makes would most definitely benefit you. You must use your '87 ECM for his PROM. 10456288 is the knock sensor number.
