Add 273's, 340's & 360's to the "318 Race" ?

Weight Heads cam gear and stall id would think would be the major factors. Not so much cubic inch. 400 hp 273 vs a 400 hp 360 really should be a tie if weight gears stall and hook up is similar.
Thanks, and the penalty box pretty much takes care of the weight, heads, cams, stalls, gears etc etc. For the 318 race, if you look at the penalty box in the link I posted, it even gave back some E.T. for wind resistance for Vans/Pickups. Will it ever be perfect? NO WAY. But I hope to get it close enough that all would have a chance. J par, last year, was the best example of having the penalty box work against him... LOL but he and we all had a blast with it.
