I just got my 350 rebuilt and put back in the car and it won’t rev past 3,000-3,200 it just cuts out when driving. I had the timing checked by the engine builder and he said it was good. What else can it be? It has a Holley 650 carburetor
What does cuts out mean? Does it stall? Does it stop pulling and go flat? Are you sure that the throttle blades are wide open when you mat the gas pedal? Have someone check.
Barring any major mechanical problems, id think its carb related. With the engine off have someone mat the gas pedal and see if you can pull back the theottle linkage at the carb further than the pedal does.
Had that happen to me, the distributor was allowing too much advance. Pulled the timing back and it would run better. Ended up changing the distributor.
I had a guy with a "Nail" in his hot rod that wouldn't rev over 3800-4K RPM's from the time it was rebuilt in the early/mid 70's. He changed cams multibil times, dist. re-curves, & on & on & on for 35+ yrs. ALWAYS came out the same. I asked if he degreed in the cam??? Which he responded NO. During all this time he did replace the timing chain, again multibul times, BUT never the gears because they ALWAYS looked good. I told him years ago many timing sets had the crank gear that was advanced & was made that way. He finally checked the cam timing & the lower gear was advanced 18*. Set the cam gear one tooth back which is 12* & got an offset cam key-way that was 6*. When done he never would have believed the crank gear could be made totally wrong. He ALWAYS thought about going the SBC route. He's so glad he didn't & endeavored on all those years.. Tom T.
My roller was ground way off. The cam gear is set one tooth to the left, the crank gear is set at 2 degrees retarded to get it 5 degrees advanced. Pulled my hair out wondering why it would not degree in. Yes I tried different timing gearsets, even cams. That's how I made the discovery. Had I not degreed it, who knows if it would have even run. The cam grinders can and do make mistakes.
