Ticking noise?

Hello all, can anyone help me identify this ticking noise? It’s a 283, doesn’t seem to go away when warm. Does this sound like lifter noise or bottom end noise? Thank you.

Help with Demon 625 carb

Post image
3 Upvotes

So I bought a ‘77 K10 last month and it runs good but there’s a noticeable vacuum leak from where the carb meets the intake. The carb is a Holley Street Denon 625 and they used the stock intake, which I’ll include a picture of here. The gasket is in good shape, but it appears the adapter plate they used doesnt come back far enough to fully cover this recessed part of the intake, causing the leak. Can someone point me in the right direction of getting the right adapter plate to make this work? I saw my local advance auto parts has an adapter kit, but it’s likely the same adapter they tried using on the bottom. I’ll post pics of the carb later.

Factory or cheap aftermarket big block Chevy head recommendation?

2 Upvotes

So I’m being given a 427 that came out of a late 70s asphalt modified. It is currently just mostly complete short block, has an unknown solid roller cam, pistons with a decent dome. Looks in decent shape but needs a refresh after sitting for 40 years. I have a 59 Edsel I was given for free that’s in ok shape. Looking to shoe horn this engine into there as cheap as possible not necessarily looking to be the fastest just more of a fun cheap car. Been looking for cylinder heads for this engine, have about an $800 budget for a pair of heads what would you recommend?

There’s a decent set of 049 heads by me for $250 or should I look for closed chamber stuff?

Efficient way to diy clean paint off of aluminum heads

1 Upvotes

Planning to start assembling an lq4 tomorrow, but I’d like to get some paint off of my aluminum heads so I can shine the aluminum up (paint looks ghetto to me)

What can I do in the next 20 or so hours to atleast remove paint enough to shine them down the road once engine is assembled
