Well ...because....I dont want to use a non crossflow 2 valve head for starters.

1. I want the shortest L series block possible for lighter weight and easy fitment under 1k bonnet. with good bore stroke and rod angle ratios.

2. I have to use the 73.7mm stroke l16 crank to do this and it will help for revving up to 8k and to lower piston speed.

3. minimum oversize bore of 87mm to accomodate the ka24e 12v head with twin 36mm inlet valves.

Can I get factory nissan rods shorter than 130.2 mm for this setup?

Could I use A series rods on a modded L16 crank since I have to get custom pistons for the 12v pattern?
