I finally have my engine in the car, now I try to tap it over and give it some fuel and spark but only seam to get spark. Every time I turn it over, the positive battery cable heats up along with the starter cable. The battery solenoid heats up almost instantly and was told it could be a bad ground but I cleaned every piece of the block and ground connections and it is still heating up. Does anybody have input or have any suggestions of what to do, as always thank you!

negative wire from the battery to the block,ground wire back of the head to the firewall, i have another large ground from the frame to the body under the car, and another ground from the block to the frame. then there are the 2 ground wires from the frame to the front fenderwells
make sure the positive wires have good clean contact at each end of the wires!!! some of those cheap premade cables from the parts stores have crappy contact! |

If it's not a ground issue, then it sounds like either the starter is internally shorting, or it's under heavy strain. Does the motor turn over easy by hand?

yeah sal may be correct.. the more i think about this, if the ground wasn't carrying the load it would heat up at that resistance choke point!!! if the starter cable and solenoid and the positive cable as well, sounds like it's either drawing too much from the starter???or something

So do you guys think it might be my starter? It doesn't bar over very easily, and the starter sounds like it struggles and lugs. I had the engine taken to a shop and worked over pretty good, so are you guys thinking heavier duty starter and better ground?

i looked back & saw that you had some problems with the trans pump & the engine/trans being locked up ... like maybe the trans pump is bolloxed during the engine install? if you have a beam type torque wrench how much force does it take to turn the crankshaft balancer bolt? with the spark plugs out (no compression)

When I got mine started this summer I replace the first reman starter because it was defective and was drawing too many amps. I also wound up with an extra 4ga ground wire by the time I was done getting it together.

Doesn't bar over very easily. Do you mean it is hard to turn the engine with a breaker bar? Can you torn the engine over with a breaker bar without spark plugs installed? If the engine is too tight, all changing grounds and starters will do is ruin more starters.

So, I called the mechanic who built the engine and he told me that it's probably gonna be running a little bit higher compression so the engine is gonna be harder to start. He also said he replaced all of the internals so it's gonna be super tight. So I hooked up another ground from the block to the frame. It's not heating up as bad but now am in need of a new fuel pump. Got everything set up to get her timed and break it in, and we weren't getting any fuel, so I pull the fuel line from the pump to syphon from the tank and it started flowing.
I could suck fuel up the line, but it wouldn't pump it, so I think my diaphragm is shot. Edited by Postma98 - 10-September-2017 at 1:13PM |

yeah sounds like it! it could be tight, once you get it started and run it to break in the cam it should start better after that.
many years ago i built an engine that was real tight...let me take you guys back, way back, to the mid 80's...times were tough! long story short... i was staying with a buddy and later his younger brother came to stay with us to learn more about cars! well one day jim tells me and his brother jack...you guys better have that engine done by the time i get home from work! jack says jim's being a jerk well as we were assembling the engine (SBC 350) jack asks me you know how they say to never mix up the rod caps?what would happen? i said i don't know but let's find out i pulled all the rod caps and a couple main caps, threw them in a coffee can and told jack to close his eyes and mix them up then hand me one, i installed it with my eyes closed! until they were all back on then torqued them down, yep they were in the wrong order well needless to say yep it was tight so we cranked it till the battery was dead, charged it back up, cranked some more, charged again... the second day she finally turned over fast enough to light off! broke in the cam, fine tuned it , that thing was wicked!!!and indestructible tire frying monster! but got lucky i guess, not that i'd recommend ever doing that |

With the fuel, if it's a mechanical pump, was the lever installed under the cam lobe or above it? I made the mistake of initially putting my Carter Mechanical back in with the lever riding on top...and it was therefore not pumping any fuel. Rookie mistake for me.

Back in the early 80's I built an engine and forgot to install the fuel pump drive eccentric. No fuel pressure. I took the easy way and installed an electric fuel pump. As far as the engine being "tight"...I call crap on that. Higher compression; yes, but unless this guy didn't check his clearances, it should turn over smoothly and easily with the plugs out. High performance engines should not be built with closer tolerances than stock unless specified by the rod manufacturer.

performance engines are built with looser clearances than stock, the only thing making it harder to turn with the plugs out should be the stronger than stock valve springs

The "for the most part," is usually identified with if a pre-start regimen is required or not. High reving, super over-square engines have very tight tolerances where the engine and fluids have to be slowly brought up to operating temperature before starting. An F1 engine with an average life of 20 hours will start and run without following the pre-start routine but the engine life span is cut to about 2 or 3 hours. Sorry I can't add anything to help Postma98. Problems like you've outlined are interesting for about an hour then they really suck. I'm dealing with a similar intermittent fuel problem but my problem is with intake manifold vacuum. The only thing I might suggest for the electrical problem is to see what happens if you hot wire the car? Make sure the key is off. Don
