If one can take the part back to the seller and hold up the offending product, especially with potential customers in the room, things get handled much more to one's satisfaction...without, I'll say, going all Karen about it.

I actually took your advice after continued back and forth with Amazon, went down to my local speed shop and low and behold "under new management"... They now will match prices right then and there with Summit now. Didn't end up getting an intake manifold but I did get a few other things like a new reverse rotation metal fan and mounting hardware. Btw when I put the new intake on should I RTV the bottom of the intake bolts? I've seen arguments both for and against( more like "no need") in the forum. I do know I need to put RTV around the coolant passages front/ rear and across the front and rear of the intake where it meets the block. Gasgacinch for the rest of the intake gasket?

Edit: found an Edelbrock 2104 locally, the guy was getting rid of for $40 and it doesn't look abused so... I'm gonna clean it and send it. Also I nabbed a Fel-pro 1205 gasket.

Anyone have any tips/tricks/suggestions on mounting and electric fuel pump? I know I need to be as close to and under the fuel tank... But do I need a relay? A switch? I was planning on putting in a pressure regulator and hard lines?

I've got a carter that puts out 4-7psi.

I don't know about sealing the intake manifold bolts. I never did, but haven't worked on newer than '85 engines, as by then I was working as an engineer, and only rebuilt old iron when I needed to.

I totally got impatient and installed the intake at 4am this morning... Because I was awake. It is on there now with a dab of Permatex thread sealer on each bolt. We will see how that works/plays out. Picture of the latest "mock-up" not sure I like the stock exhaust may go back to the Ram head manifolds and I want to figure out if the old PS pump will mount on the serpentine bracket. Then I won't have to figure out new hose(s).

As a kid I was taught to put a piece of wood underneath your battery while charging it. I don’t know if it’s an old wives tale or not but I always have done it.

I dunno if it is a wife's tale or not but that was literally sitting there for about 10 mins and I put it up on the shelf behind/left ... So I completely understand *laughs*

Stock (old) temp sending unit is bad and new ACDelco temp sensor is too big for the driver's side head "hole" between 1&3 on this block... Fits old block but not new. I don't know where to go at this point besides stick the new sending unit in the intake manifold? New unit matches old stock unit

Similar here…only that having the battery on the concrete depletes its charge. So I’ve always placed them on a piece of wood.

Putting the stock sensor in the intake manifold will work just fine. And it's less money than buying one that has been machined to fit the head.

That looks like '73 up manifolds. Rams horns are stock on 67-72 small-block. And the truck rams-horns are different than a car the way the outlet is. You will probably want to use your originals.
