Going to Build 470 Street/Strip Engine for 71 Demon

Yeah, i accidentally found those by looking 1.32 CH 4.375 Bore Pistons from Summit. Atleast those seem quite nice pistons for price.

Wow thats alot! Here 300cf argon bottle fill alone cost about 500$.
Wow, holy crap. It's about $120 here.
It was about $600.00 to buy the bottle and gas.
I just kept stepping up in bottle size after I ran out. Luckily the 300 didn't cost me anything more than just the fill because they didn't have my smaller bottle which I think was 250cf
