Rough as HELL......
I readjusted the valves, pushed the down 1/4 turn and locked them tight.....as suggested by DJ Crit......and really no diff in the rough running.....I have no clue as to watt is the problem......getting into an issue of cam timing off a tooth or what???
'89 4 bolt main block, roller cam-L98, LT1 intake with HEI up top where is belongs.....I do have ceramic plug boots on there......and they are a bit loose feeling, but never an issue in the past.....tired of spending money, and getting tired of working on it..... Any suggestions??? |

Just drop in a simple small block crate engine with a carb, mechanical fuel pump and HEI Distributor. It will be reliable enough for your purposes.

Nuke it from orbit. Many of us here have tried to advise you. You are a stubborn man.

Since you first started on this, it's been quite an adventure in disappointment.
At this stage, I'd do a compression check just to see what cylinders are affected. I would pop the water pump and pull the timing cover and check the cam/crank index marks. That would rule out valve timing. If that's good, your distributor may be a tooth or two off. verify with timing mark. I feel your pain, Gene. |

Call DJ's fam.
Ask them what could you have messed up after the work. I have had good help from family shops that have worked on my stuff. |

Spark
Compression Fuel Air You said its running but rough, so you do have "spark" Compression and air.... Get back to the injectors/rail O rings and regulator. To repeat others, again while its running pull off one plug wire at a time, if no change that cylinder is not operating/firing/ or getting fuel..... |

My suggestion is he removes the hood, pull the air filter cover off, hold it just above the engine bay, then roll the vette out from under it. Roll a newer running vette in place and secure the air filter cover. Problem solved.

I put a 351 Windsor cam in my 302 and had to change the firing order. Quote:

He's got a mild mid range cam for a 350 sb. I'm sure it didn't jump time or that the cam was installed wrong because he's not hearing any metal on metal stuff banging into itself when the engine tries to run.
Gene, you got fuel. check the spark first. You could have a bad distributor. |
