I did a study a while back on Pure Stock PSMCD from 1998-2015.
I looked at a weighted average trap MPH (to get rid of anomalies like a single incredibly fast MPH done once) and ranked all the engine combos by MPH.
To combine stick and auto I added 2mph to all the auto trans cars which I find correlates mighty close from that era. That let me average more runs over the years.
Heres some of the rankings:
RANK MPH #Runs Engine
1 119.2 41 426hemi
2 116.7 13 427-L72-COPO
3 115.8 38 400ra4
4 115.0 32 454LS6
5 114.6 50 396L78
6 114.5 53 440-6v
7 113.0 36 455ho&sd
8 112.0 12 409-8v
9 112.0 41 455stage1
10 111.5 37 428CJ
11 110.3 63 400ra1ra3
12 109.9 47 455w30
13 109.0 3 351boss
14 109.0 3 302boss

19 107.0 11 421HO

That covers the Top 14, all the Pontiacs I found in there, and the Top BOP and FoMoCo, sadly down at #10.
I don’t think anybody was running their 427 Fairlane or Hi Riser Galaxie (if they’re even legal in PSMCD). To FoMoCo’s credit though, they did take the top 2 small block spots.

The last Pontiac on the list was the 421HO at #19. The other 3 Pontiac engines that showed up all made the Top 11. I didn’t see any RA2 cars in that 1998-2015 PSMCD era.
