Thread: Engine won't start!

Tweet

Hey guy's. I have finally finished putting my engine in my car and I can't seem to get it to turn fast enough to start. Some info is in order here so you pro's can help this weekend warrior. The engine is a 1970 460 with dove c heads which I had the machine shop install bigger cobra jet stainless valves installed. Hardened valve seats band a three angle job. The block has been bored 30 over and the crank undercut by 10. The pistons are sealed power dished with the two valve reliefs. The cam is just an edelbrock performer and the intake manifold is as well. the ignition was converted to hei and the valve train is except for the cam it si stock rockers and pushrods which are all brand new. The engine has spark and fuel but it seems to me to be dragging way to slow for it to be able to start. I dont think that compression is the problem as the pistons I used give 9.79to 1 with my heads. I have a powermaster starter that is rated at 10.00 to 1 max. I am at a loss here as to what is going on. I am guessing starter. The engine turns by hand although a little tight. What do you fellas think...............

WHat do you have for Hot and ground cables???

The battery is mounted in the trunk with a realocator kit I got from summit. I can't tell you for sure how thick the cables are gage wise but the ground at the battery in the trunk is attached to the bodythe engine itself is not grounded now that you mention it. Could that be a Factor? I did forget to attach gfround strap to the engine.............

That one will get ya every time.. I had a 460 once that was lighting the spring on the throttle cable up like a toaster element because of no ground cable to the body

Could it be just that simple as a missing ground from the engine to chassis? It does crank though, Slow, but does crank.

It could easily be that simple..If it still turns slow have someone else crank it while you feel the cables for excess heat.. Any weak link or connection will get hot..It takes a lot of amperage to turn those 385 motors..

00 wire then. OK should I run the ground from the battery in the trunk to the front or grounding that one to the trunk floor is fine? Just replace the current cable from the batt to the solenoid under the hood with the thicker cable and add a ground cable from block to chassis?..................

those cables that come with the kit may not be enough.. 0 gauge is what you want. I think that kit comes with 2-3 gauge.. 00 welding cable is often used in this app
