I would say if it’s any kind of stroker at all, you’re already past that point… I’ve know of at least one member with a hot stock stroke 340 that have went faster going to an MP single plane from an air gap, with the time slips to back it up.
when i was 20 i bought a pumpkin off a 45 yr old guy in early 80s
He had bought a brand new 69 notch cuda s 340 727 3.23s he bracket raced it for 20 years. He told me he tried every setup they had cams carbs intake gears
He settled on stock cam advanced tm5 single plane 700dp 3.55s 50 series street tires they were wider then my L-60-14s factory manifolds and exhaust spring clamps
His dial in was 13.1 it ran 13.1@104 he had quite a few Trophies
He had a stroke 7 or 8 years later at a grudge night caught up with him the car hadnt been run for awhile he said the carb was acting up it bogged of the line blowing black smoke out the tips still ran 13.3@101 mph i laughed and shook my head.
stock 340
intake carb 3.55s low 13s
10 trophies or more in his basement
