Just checked the running and driving with the rev limiter removed. The coil or something is cutting power out at WOT around 35-4200 rpm
I replaced the coil, cap, and rotor with a DUI Ignition piece, and if anything it breaks up worse at 3500 than it did before. I am almost certain it is not fueling, because I can wind out the speedometer a little in top gear, where load is greatest, sort of like a dyno brake, and there is no stuttering or bullshittery. However, if I downshift into first and then put the switch pitch in HIGH when I floor it, it comes right up to 3500 and begins to miss like Hellen Keller playing darts. I'm thinking the module is the only thing left that is gacked, and I have one on the way that will be replacing it.
That was the culprit when I dynoed my 470. Nice and smooth up to that point and then started missing. Swapped out the module and presto strong all the way thru the rpm range
Another new list: 1. Window regulator 5+ hours ✅2. Need a Snell Helmet 30 mins 3. Dust off the whole car, it’s super dirty 30 mins ✅4. Verify the 1-2 and 2-3 shifts 5. Headliner a long time ✅6. Rear coil springs 3+ hrs
Alright, I didn't expect this coming, but I've seen a great deal on a local 6.0 LS with a 6L80e with the necessary conversion kit to mount it in the Riviera. I'm really getting tired of adjusting the choke, screwing with the carb, and want some easy computer controlled fuel injection. It's sitting in the parts yard until I grab it with my stepfather's truck this weekend, but by the time Corona passes, I'll have a 6.0 LS Riviera, and great highway gears to go with it. Some big things to change: Another list: 1. Engine mounts 2 hours 2. Fuel system 5 hrs 3. Headliner? 3 hrs 4. trans controller program 4 hrs? 5. Mount tranny and engine in car together 6 hrs This is just a small start, but I really want that overdrive gear and even more power to make this thing a comfortable cruiser and even faster racer!
Correct! I was inspired by another member of the board with his All Wheel Drive Skylark, and I'm getting ambitious. I think it can be done on a Riviera. Worst case, I just remove the transfer case.
You gonna part the 430 out, sell it and the trans whole or just shelf them both for just incase you sell the car later on?
Probably gonna hold on to it, unless I get a good deal on parting it out, not sure yet. At least I have time to decide
That's certainly true, but first I want to get it nicely cammed up and running, and then later I'll be able to make the decision to turbo it or not.
Anyways lol, I wish I had such good and funny news as before. I’ve now swapped the HEI module, the HEI cap and coil, and am still getting a break up around 3500 rpm. What gives?
What kind of wires do you have? Are you absolutely sure that the firing order is correct? Check the simple stuff.
