    What have you done to your square lately??

    I have on the oil gally plugs however I've also never done the external ones myself the machine shop has always done them when they've done the work on any of my blocks, cam bearings as well. Funny of all the engines I've done over the years I've never touched the water jacket plugs myself...

    SBC Build Questions

    If you just have the deck surfaced (.010) and install flat tops, you'll be in the hole about 15 thou stock bore and stroke and a 4.030 bore gasket with a crush of .039 and a 64cc chamber will be roughly 10:1. May need to go to a piston with an 8-10 CC dish to get down to 9:1. The 8800 has a...

    Chuck’s engine build thread!

    Both my Flotek flat tappet heads and my Edelbrock roller race heads look like this and there is 2k in price difference between the two pairs. Typical for SBC I can't recall seeing any that didn't stick up that high. Looks like the Howards is trying to compensate for spring pressure buy raising...

    What have you done to your square lately??

    Stuck my camera in everywhere I could to get a good look at both sides of the block and thankfully don't see anything. Nothing in the oil fires right up no noise no steam or smoke so think I got lucky. Driver side. Passenger side over starter. The hole the plug came from is rusty.

    LS rear main seal leaking

    Even if it doesn't have a cooler, it could still have a block off/bypass plate that has a gasket that could leak.

    What have you done to your square lately??

    I'm really hoping that's the case as I don't believe it got below -20 which is what the mix was at. The side of the plug shows no signs of any kind of sealer, and the surface of the opening feels a bit rough so maybe the block just shrunk and spit it out. Downside is it's the one behind the...

    What have you done to your square lately??

    Weather has been nice here so decided to check my fluids and fire her up. Oil looks good and is full I pull the rad cap and no juice, climb underneath to see if its leaking some were and immediately see this lying on the concrete. It's the one from behind the engine mount on the passenger side...

    Reverse rotation water pump

    The aftermarket billet aluminum water necks can be rotated 360 since they are multiple pieces, the valve cover clearance may still be an issue however.

    Spark knocking, pinging, detonating

    Probably too lean at the carb. Are the idle air screws set around 1.25-1.75 turns out? What hole in the arm is the accelerator pump shot set on?

    What have you done to your square lately??

    The fenders on it now are full of dirt and junk probably why they have a ton of filler in the lower sections that's now breaking up and starting to fall out.

    Ordered a set of these fender filler panels hopefully they help keep a bunch of road debris out of the new front fenders, since I'm not running fender wells...

    Aftermarket Carb

    You have to be careful as a lot of the knock off carbs are straight aluminum not an alloy, so they corrode and pit very quickly if left to sit especially dry for a while. Went thru this with a knock off 4 barrel on a friend's truck I ended up swapping on a spare 600 Eddy I had sitting on my...

    Lower fire wall panels. Anyone make em?

    I'm not running fender wells as I have fender well headers. I have not seen anything to fit in that area as I was looking for something to keep the junk out of the fender itself and had no luck. Looks like it might be a fab it yourself kind of deal.

    Flipped axle Caltracs?

    I run them it prevents axle hop and you can pre load one side to force the rear end to steer under torque.

    Horn wiring question

    Just on a quick search of GM stock wheels, one popped up listed as 88+ s10-s15 blazer but could be listed wrong. Defiantly not a C or K series wheel I know of.

    Horn wiring question

    Think that's an s10-s15 wheel. Can't tell from the pic but the plastic tube should stick out that hole looks like they broke it off maybe not (maybe the pic angle) either way the wire isn't in there might need to pull the wheel and the plate and put a new cancel cam in it if the end with the...

    Steady 5.5psi fuel pressure drops when warmed up

    Probably heating up the fuel which thins thus less pressure.

    Steady 5.5psi fuel pressure drops when warmed up

    I doubt a stock pump is making that much pressure my aftermarket Holly claims 8 I get 6 on the inline gage feeding 2 4s on a tunnel ram idling at 1k rpm. That's not running just residual after shutting it off.
