88 C1500 Engine Swap Question

5874 Views 13 Replies 6 Participants Last post by  Big6ft6
I have an 88 C1500 with a 305 and I want to install a remanufactured 350 but I don't kniw what to order. There are so many options such as a two or four bolt main and different lifters and such and I don't want to spend 1500 dollars for the wrong thing. What do I have to look for when ordering an engine so it will bolt right up to my 4l60e? I've done a ton of research to no avail. Any help is greatly appreciated.

I like your idea-Forget rebuilding the 305-all that machine work?? all that time-learning curve-
just use that engine from Summit-it seems to be an actual GM engine??
you will easily be able to bolt on your intake manifold tbi dist etc might buy a new water pump-or rebuilt
yeah forget the turn key stuff-too expensive-forget rebuilding-heck it would still be a 305-and all the machining etc more potential for something to get screwed up-or to make a mistake reassembling it-and having to pull the engine-and fix redo something-learning curve-first time i do something complicated-fair chance I will screw it up-spending more time and money re-doing it-learning curve

Right- no free lunch. Nothing easy or cheap about changing an engine
The long block-more or less what he is getting except I think the one he selected comes with valve covers-maybe with a oil pan
Below is the list of stuff-plenty of work involved

e: Chevrolet Performance 350 C.I.D. VIN Code K Engine Assemblies
Summit Racing Part Number: NAL-12568758
Engine Assembly Style: Long block
Crate Engine Cylinder Head Material: Cast iron
Assembled: Yes
Engine Balance: Internal/External
Intake Manifold Included: No
Cylinder Heads Included: Yes
Carburetor Included: No
Throttle Body Included: No
Distributor Included: No
Oil Pan Included: Yes
Valve Covers Included: Yes
Timing Cover Included: Yes
Water Pump Included: No
Harmonic Balancer Included: Yes
Flexplate Included: No
Flywheel Included: No
Air Cleaner Included: No
Spark Plugs Included: No
Spark Plug Wires Included: No
Computer Included: No
Wiring Harness Included: No
Rear Main Seal Style: 1-piece

So yeah-pile of work-dist water pump flex plate flywheel etc- plenty of work-and plenty of ways to goof-
I'm not sure if the 305 and 350 flywheel flex plate interchange-and are they "bolt on" or do you actually have to balance then in some fashion?? Guessing they are bolt on-but wouldn't be surprised to find out there is something tricky about "bolting them on"

Still the drop in engines-are soooo expensive-
