Slightly warmed up /4 motor applications...I'm thinking just about any design better than none at all....I'd like to metal spin these myself, however if I can get a good price on 8 from a fellow non-club member, I'll go that route (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

Something to think about, are you going to run air cleaner(s) and if so which ones? Or are you going for the tall Hilborn injector Can-Am look? When my race engine was dyno'd taller stacks were used and I had to go to taller filter elements which just about touch the engine cover on the 914 and that is with the enging sitting an inch lower than stock. The taller the stacks, the higher in RPM range all things being equal but for a given cam, head combination there is a stack height for the best power production and mine happened at 7000 RPM with the parts we had.
