    Engine block ID

    Read the number backwards and was missing a 1. It's a 350 4 bolt main. Thanks

    Engine block ID

    My stepson brought home an '86 or '87 K20. I mentioned this truck about a week ago regarding horsepower, and swapping it for my '86 C10's 331. I finally got a chance to see the block number to actually see what we have going on and it reads 9809900. Can't find this casting number to identify it...

    Horsepower

    Thanks for your input and most valued info, but with the help of the gear heads I know, it shouldn't be a problem. Thanks for responding quickly.

    Horsepower

    Regarding Frankenchey's reply, heard the 350 run last year and it sounds nasty. Never heard the 327. Both are in vehicles on my property. Like the 350, could even be a 355. Leaning that way. Thanks.

    Need a vehicle to drive. Clean swap for the 350, or hold onto 305 while 327 gets work

    Horsepower

    How much hp can I get out of a 327? Depending on heads, crank, cam, carb, etc. I can get it for free if I want it. Can also get a worked 350 but it was used in an '86 Custom Deluxe plow truck then sat for years. Worried about rings, bearings, and such. Having a hard time deciding. Either will be...

    Strong gas odor

    That's something I wasn't aware of. I'll have to get in there and have a look. Thank you.

    I can raise the bed this weekend to check that. You've given me (along with others) a decent checklist. The hits just keep on comming! Ha

    Electric choke simple wiring

    Would that factory tapped port be occupied by another switch or similarity? Because I'll be looking to use that as an option for my oil pressure switch as well. Thanks chengny.

    I'll remember that when I replace mine. Thanks for responding.

    Strong gas odor

    Thanks Brian, yet another possible cause would be those hoses, and I can live with the cost as long as the problem goes away and I'll be checking them along with the other helpful tips I've received. But my gut feeling is leaning towards engine bay. I got in the truck this morning and it was...

    Strong gas odor

    Thank you chengny for that detailed info. This is without a doubt my weakest area (schematics and carburetor). I tried to read book explaining the workings of holley carbs and it sent my head spinning. Your the first person to give me a direct proper answer to my problem. This I will learn.

    Strong gas odor

    I believe it does, but the choke light stays on at any psi. Would an electric choke with a bad ground cause this?

    Strong gas odor

    Will do as soon as I get home from work. Worked on steering column yesterday and found that the odor is definitely engine bay related. Thanks.

    Strong gas odor

    No visible fuel leaks. Vapor can and all other emissions disconnected by previous owner. Crawled under truck searching for worn or cracked lines, tanks, and leaks. All good. Seal for sending unit is going to be looked at asap, good tip, thanks. But still very frustrated with choke light...

    Strong gas odor

    I purchased a 1986 C10 Silverado in May. Since then the choke light has stayed on while engine runs and runs great. Has a 305 0.300 over and mild cam. Quadrajet carb with an electric choke and engine is very clean. Oil pressure is at 60. For the last week or so I've noticed a strong gas odor...
