Check the timing belt.
vmax84 Just kidding. That sucks. Nice looking ride but I can't even begin to imagine how much money it takes to keep running. Hope it's nothing too serious. |

Awe it's just low on blinker fluid, top it up and it will be fine.

So what was your R/T? Posted Via AR15.Com Mobile Not sure, never made it the end to get my time slip. What's funny is I won the round against a red light... |

If you could here a noise @5400 it was'nt a small noise!
Maybe you got lucky and it's electrical! |

sweet looking car..I remember the threads back when you were building it ...hope its not too bad

If you could here a noise @5400 it was'nt a small noise! Maybe you got lucky and it's electrical! It cranks alot faster than it should. It is/was 14.8:1 and you could tell by the cranking that it was high compression. Now, it cranks fast and easy telling me that the compression is gone. When it turns over, the balancer moves so I know the crank isn't broke. When I get it home, I will first see if it has oil pressure during cranking, then remove the dist. cap and see if the rotor spins during cranking. That should give good indication if it's the chain/cam. If it was the chain that let loose, at 5400, the heads and all the valves are shot. |

Look at the rockerarms. Valve bent? |

Oooops..... Time to get out the gold card. I only wish I could afford to race a car. Riding motorcycles is my hobby and they are all I can afford at this time. |

Maybe you got lucky and broke the timing chain/gear. In a 14.8:1 compression engine that would be lucky! ...but it would be very BAD luck |

Look at the rockerarms. Valve bent? I didn't look at anything other than to make sure there wasn't a hole in the block and that the crank was turning. I have another car that I race (Vega Wagon) in Sprortsman and had to still concentrate on losing in it. I loaded ithe Camaro up and put it out of my mind until this morning. Have to go the track later and bring it home. I drive the Vega there and back so the Camaro comes home on Sundays. |

A broken timing chain is no luck thing on a high lift motor with high compression at 5,400 rpm. Usually things meet.
Chains are usually pretty silent when they go, just hop you are loosing compression due to a valve being stuck open and not a valve head wedged into and being friendly with another valve. |
|
I had the roll pin on the distributor gear shear one time-acted just like that.
No turny the distributor gear, no sparky=easy to crank. Pull the cap and make sure the rotor is turning. Nick |

That would be ok, I needed to upgrade from those chineese made, bottom of the line, super flimsy, Brodix Track 1 heads anyway... |

its a big block........?
anyway sorry to here it 's broke... (i'mandoldhasbeen)racer |

That sucks, can't trust those damn GMs. Hope it's nothing serious.

Nick Usually the case when you loose spark or fuel the motor will crank fast, Not so much with high compression. Tho it cold be. I would like to help you out with a new set of heads, I see a few hundred brand spankin new ones everyday at work. I think they would notice if I walked out with a set though. The guys who pack the finished ones are pretty sharp. |

You really need to be running a gear drive instead of a chain for the RPMs you are running.
I would bet it jumped timing. |

Sounds like it jumped time and bent a bunch of valves. Is it a chain timing set, gear drive, belt setup? Here's mine: http://i272.photobucket.com/albums/jj167/ReSSurrected_SS/454/IMG_0763.jpg NICE! Chain & small block 406. It will have gears next. |

What's puzzling me is that you indicated by the way it cranks that it still has high compression.
Did I read that right? Fast, easy cranking doesn't go hand-in-hand with high compression. Unless you're using a 100 HP starter. I'm not going to try to diagnose anything other than "It's broke. Now investigate and find out WHAT broke.". I just want to hear the results of the investigation. CJ |

Worst I've ever done was float the valve train on a missed power shift and broke20 or so springs
in the heads (inner and outer) on both intake and exhaust side. Thank God the keepers held the valve stems from dropping into the bore and punching holes in the block (Got VERY lucky). I also broke the lifter keeper in the lower intake one time and had 2 sets of roller rockers shift sideways and wipe out the lobes on the camshaft. That also sent shavings throughout the motor so that was ANOTHER full rebuild. Worst one I heard about was a roar racer guy at Bridgehamton lose the motor and the end of the long straight due to overreving (too steep rear end gears for that course). He busted the crankshaft in 3 places, took out the oil pan and oiled his rear tires at the end of a 130 mph straight. He ended up about 100 yards into the woods - but was OK |

Broken camshaft ................that sounds like what it is to me.

Low compression? Meh, just dump in a can of Restore and it'll be fine.

I recommend gear drive for all race engines. Noisy as hell but its a race car. Sorry bout your engine though.

Bummer. Looks like a lot of fun!
What class? Typical pass times/speed? |

I remember when you rolled out the blue painted headlight doors. Many here said how shitty it made the car look.
