I don't know much about cost but a little about cyl heads for Super stock heads I believe the class was.
I don't know if you guys have heard of Bob Lambeck (SP) but @ the time him & his son used to race I believe 1990's Camaros
The engine of there choice was a standard 300 HP 350 SBC's
you had to run 10.25 compression, stock volume heads, porting was allowed, had to run factory sized valves.
Exhaust manifolds had to be cast iron, they were cut opened & ported then welded back together. Same for the intake manifold.
IIRC, the best time they ran was a 9.7 in the 1/4.
The heads did not look anything like stock, the short turn radious' was a big difference, the intake ports were raised as much as possible.
The intake port was really smaller & narrowed. (they had to have stock port volume)
They were all epoxied up w/a 2 part epoxy.
IIRC, the heads flowed about 300 CFM ( I would have to refer to my friend that did his cyl heads)& the engine made alot more than 350 HP, can't remember off hand but maybe around 500 HP?? It's been a while.
The pistons were super light weight, short skirts, lighter smaller OD wrist pins, low tension piston rings.
There is a lot to mod a SBC engine just to be competitive.
But I am sure there are faster cars now, but can you imagine a 10.25 SBC 350 running 9's.
The cars would just hook, wheelie & go! Big tubbed rear tires.
