Been having progressive louder engine noise, today I heard metal on metal. Like sounds of something flinging off into the oil pan. So I dropped it off at a buddies diesel truck shop for a lower rebuild. Thoughts on parts to upgrade from stock with this rebuild? Bigger cam? Or shipping it...

It had a computer controlled quadrajet originally with all the smog crap that didnt work right on the 307. Im not sure if I have that carb still to turn it in for a tune job. I also have an Edelbrock carb somewhere that I’ve used on this 350. But this Holley has no adapter, just the thick tab...

Ok. I have one of those plastic see thru fuel filters between the tank and the fuel pump. So, before the fuel pump, but right next to it. The gas tank is new (couple years old). There was also a carb stutter on this drive each time I started from a stop. Maybe that was the hint that it was...

I took all of them out regapped the To .035 then realized I had changed them when I installed the engine. I changed the wires. Set the timing again, higher to 34 degrees total at 3,000 rpms. Then I drive it 100 miles tonight most of it was 70-75mph. Got to my destination did some driving...

I took a plug out, it was clean. AC Delco R45S it was gapped tighter than .040 but more than .035

Awesome. Thanks for help and info!

Yes the engine is a 1972, 350. But the car is a 1981 Olds 98 Regency. Was told, it was rebuilt and used at the circle track for a couple races. I bought the whole engine used for $1,000 in Florida. Whats the difference between an olds 350 and a chevy 350? When I went to Napa looking for a new...

Well, all Napa had were AC Delco’s 43S Should I hold out for the NGK 45XR ? As Recommended?

Its a 4 door, never will be fast.

Will do thanks. I was looking at headers since i cut the exhaust off. As much as I like the loudness I couldn’t do it all the time. Just a glass pack for now. Recommendations for headers or stick with stock manifolds?

Good news, long story short. I installed a new cap a rotor then had wires switched between 4 & 8. And I couldn’t figure out what was wrong till tonight. Now it runs great. Was able to drive it 60 miles at 70mph. Does good on the long hills on the highway. I feel a hesitation on the highway in my...

I cut the entire exhaust off before the cat. Added the mechanical adjustable fuel regulator back in and its at setting 5 and then it was running rough so I enriched it some more and it smoothed out. Added a second temp gauge downline from the thermostat. It shows about 10 degrees cooler than the...

Its a mechanical pump mounted next to the water pump. I’ve run into this issue before with getting too much fuel except on the 307. Thats when I installed the summit fuel regulator. 5 different settings.

Im not sure what kind of curve is in the advance how do I find out? I did notice the secondaries dripping fuel at idle after I removed that selectable fuel regulator, are they supposed to be, or only during a call for wot power? I read online that vac advance liked ported vac better (below the...

I made it home earlier with one foot on the brake and one on the gas keeping the revs up. I could feel the engine missing on a dead spark occasionally on the flats. Ordered a new module. But when I got home it idled fine in the driveway. Will cut the exhaust tomorrow ahead of the cat and see how...

Yes when I ran it years ago it had a hard time starting when hot, like the starter couldn't turn over. Its starting a lot easier now when hot now that I retarded it 8 degrees. It died in town an hour ago, this engine has always ran hot. I have an old analog/bulb type temp gauge and it reads...

I drove it to town 30 miles just now, it has problems on the hills. It will lose 10mph with it floored. But on the straights it’ll go 75. Air fuel meter reads 10 with it floored, but during straight cruising its 12-14?

Well I removed an old inline fuel regulator between the pump and the carb, switched vac sources for the tranny. There was a rear and a front one. Then I adjusted the holley carb so that that the secondaries open at least some. Noticed a big difference pulling out of the driveway. Got up to 75mph...

Its not the stock tranny. Its just a 3spd. What do you mean the zero timing mark should point to the passenger side? The timing marker itself is mounted on the drivers side of the balancer. Then if Im looking at the engine from the front, zero is on the drivers side and it then goes 4 8 12 16...

I got to thinking. When I unpinched the vacuum advance while checking timing the timing then jumped the correct direction on the timing marks further counter clockwise. The engine is smooth, my air to fuel ratio gauge is around 12, the engine screams when I floor it even at a max speed of...
