12 Second N/A Slant 6?

I like what I am reading here now and seeing now that you're spending way more money than I once thought ( I was in the $2K budget range when you said not much money) I can now take this build seriously.

So we're looking at 198 Rods and 2.2L pistons: Awesome!
Aussie Speed Bolt ons: Also Awesome.

Since you are shooting for a street car and nitrous I know you are wanting to keep compression down but here is food for thought.

Ever heard of water methanol injection? Basically inject water and mehtyl alchohol into the combustion chamber to slow combustion. With water meth injection you can basically turn 93 octane fuel into 106-110 octane. I don't know how this will react with Nitrous but food for thought?

I'm lookimg primarily for a N/A perormer that will take a moderate shot of nitrous.

I ran 10.4:1 on my 5.7 W/a custom cam that made 235# of cranking pressuer.

i wa sstill able to run aggressive ignition timing W/O spark retard until the trans shiftednto 4th gear (3.23 FDR & the engine lugged down.

I was still within 4° KR.

Tried W/M using the windshield washer resevoir but never saw much benefit. Some windshield washer solutions are high percentage mnethanol.

If I can't hit 12.99 when the DA is right at sea level or lower I settle for 13.4 or whatever. Any 13 second pass in high DA would be acceptable.

I've raced from MIR/Englishtown/Atco where DA can be negative in the spring & fall to Columbus, Ohio & Beanblossom, Indiana where DA will be way up there.

Must run on 93 octane unleaded, no W/M injection. Designed for maximum N/A performance, not a juice engine 10.5:1 CR. I just want to run a shot now & then.

A/F ratios can be run rich on the juice if needed to prevent detonation.

Are aftermarket or modified rockers an option?

Just what can I expect to spend on aftermarket (high ratio) rockers & how much for a set of ported heads W/oversized valves & valve spring/retainers.

I'm not looking to spend $$$ for high RPM use. I want heads that will breathe from 3000 to 5500 RPM W/a cam to optimize torque throughout that range..
