drop in 12.5 to 13:1 compression pistons...

have the heads stage III or stage IV prepped..

custom high lift cams, springs retainers to handle..

10,000 rpm or thereabouts.

balance the crap out of the motor..

i assume custom tune/standalone.. and of course a hand built exhaust from the exhaust ports back..

run race gas (you can get 100 octane no-lead) or 105 octane e85 (adjust fuel lines, pumps and injectors as neded)..

the thing is its about the amount of combustible energy you can get into the thing in a specific period of time, since you dont go turbo or supercharged, to get the requisite combustible materials into the motor in the same amount of time, you gotta spin that sucker faster..

add a low gear ring and pinion to make it work on the street..

and about he small blocks having more stuff available cheaper.. they've been around more than 50 years.. 50 YEARS.. and have simply evolved. there is a tremendous market for parts and thats why there's so much more..

if i was gonna look for more power out of the 370.. first hunt would be for a super charger. cosworth came out for one for the miata.. i think its about 5k, i would assume eventually similar products we bel available for the Z, thats probably the easiest and safest way to get your 'instant on' powa....
