Good morning gentlemen – I hope this finds people as well as can be in these weird times and that everyone staying safe. I am in the process of dressing my GM performance 350 crate engine and I had ordered a standard Carter mechanical pump for it but the actual mounting surface on this block is incompatible. Did they change the fuel pump set up for recent crate motors? Do I have a adapter kit or something that I need to buy? I’m sure this is pretty basic but I’m embarrassed to admit it has me a bit stumped right now. Thanks
Looks correct to me. Just the plate ( usually chrome) and a push rod...I like header bolts to attach the pump. Remember to put a short bolt in the front or you will have an oil leak.
Jimmy is right, here is a picture of what you need. Sent from my iPhone using The H.A.M.B. mobile app
by the looks of the remains of the gasket on block you obviously removed the plate.better start looking for it and the rod also.
Thanks for the fast and very helpful responses. I unwrap this engine but I didn’t remove anything, so that stuff in the block is a bit weird. In any case I think you guys put me straight here, let me get that missing plate and off I go. Thanks!
Why does it look like the plate was glued on at one time an d rust in the hole? This is suppose to be new !?
I believe Jimmy mentioned the pushrod in the second post? Whats the muddy fuel line? I'm kinda miffed by the picture. As was asked, this is new? Lippy
I am not seeing anything out of the ordinary here. Is this a trick? What am I missing. There is a big hole, with 4-bolt holes. Two of the bolt holes are small, and two are large. They all hold the access plate down, but the top two also hold down the fuel pump. The hole is as big as it is, so there is a straight path to use to put the fuel pump push rod in the block, all the way to the cam. It can be retained by a single long bolt on the front of the block, if that goes through, or by putting some grease on it. That will keep it up and out of the way. Once the pushrod is in, the access plate goes on, with a gasket, and is held on with the bottom two (small) bolts). The fuel pump is then slipped in to the oval hole in the access plate, making sure that the lever goes under the end of the push rod, with another gasket. The pump is retained to the block by the two larger bolts, which also sandwich the top of the access plate. Attach fuel lines, prime system, do burnout. Did I miss anything?
The only SBC engines that have any changes first lost the fuel pump pushrod hole (EFI), but kept the mounting boss. After that, even the mounting boss disappeared (also EFI). All of the replacement engines sold by GM, that are not specifically intended for a specific EFI application have the mounting boss, and a lobe on the cam for a fuel pump pushrod.
Remove the long bolt that is holding the push rod up and replace it with a short bolt that doesn't hit the rod. I tend to remember the things that I have been bitten by.
One more thing to make the install easier is to hold the pushrod against the cam shaft while rotating to engine so the rod is on the base of the cam lobe. By doing this there is less tension on the fuelpump lever when it's bolted to the block.
After getting pump rod on cam base as fogger suggested, I have used a hack saw blade between rod and pump lever. Get the pump bolts started, remove the blade, tighten bolts. The bolt hole on front of block doesn't extend into fuel pump cavity on my crate motor. Phil
pprather, you hold the push rod up in the hole with one of the 2 mounting threads that were used for the 55-57 Chevrolet on the front. A finger tight on can hold it, it was mentioned above. If you don’t put in a 1/2” Length 3/8-16 in the hole it will leak oil.
@jimmy six My front engine mount holes do not go through to the fuel pump cavity, thus the blade trick.
Good idea to hook up a remote start switch to the engine and crank it over as you put your fingertip over the end of the pushrod. You want to be sure your camshaft has a lobe to operate the mechanical pump, before you get it all bolted up, and don't get any gas to the carb! Most aftermarket camshafts for these newer roller motors have the fuel pump lobe, but not sure about the newer crate engines?
Funny, I’ve never seen one without the thru threads for a bolt. Even our Dart SHP has it..... But then again I’ve lived a very sheltered life.
