G'day Ari, i know what you mean! Its got ported '883 heads, a moderate cam of unknown specs but as the rest of the engine is set up for gas i'm thinking its performance gas grind of some sort. Standard 4 barrel manifold with an Impco 425 straight gas carb and a Scorcher gas dizzy. Plus the pacemakers as well too. So plenty of room for improvement. A dual quad or tunnel ram will allow me to get the flow i need with two impco 425's. The '883 heads are usually crappy but its had the ports opened up a bit....i still think they need to go though. The power its putting out is about right for being on gas, but i want more (havn't we all heard that before). I think the big limiter on induction will be how far out the bonnet i can go, i don't mind a low bonnet scoop if i have too, but those tall things you see look dumb, and beside if you got it flaunt it.
You got any good suggestions for a manual gearbox Ari?
