If you don't mind me sayin' you should be able to easily get 300-350hp out of a 308.
Yes, I agree. One rule is naturally aspirated: 75-100 HP/litre.
I am playing with a few things at the moment before changing the engine. That is 1) ignition system and 2) fueling. Both of these systems can be changed over to the other engine.
1) Ignition System
I've upgraded to a multi-spark ignition unit (Mallory HyFire 6AL2) with a magnetic breakerless distributor. The system works great and I feel things have gotten a lot better at low rpm (up to 2000 rpm).
I first had a distributor and ignition box from PRO COMP electronics - but that failed after just 2 months. I've then bought a proper system from Mallory and it works well.
2) I will change from the carby to electronic fuel injection. I've done a lot of research on the topic already and have selected the Holley HP EFI system (P/N 550-412). It's not in the car yet but I'm working on it. It's a great EFI system that can adjust timing and AFR on a number of inputs (oxygen sensor in exhaust, knock sensor, fuel/air pressures and temperature).
I can hopefully post some results here soon...
