Basic Engine Upgrades--Jet size?

[santamaus]

Heya--I've got a L26 that I'm putting fresh air filters (K&N) and a freer flowing pipe on. I may put a new cam in it in the near future, but that can wait. As long as I have the carbs off, should I be increasing the main jet size?

As for parts, should I shop further than what's in the Motorsport catalog? How is the 17033 cam in there? The springs? I've heard that Crane is good? What about the Taylor spark plug wires? I already have an upgraded distributor--a high perf coil worth going to with the wires?

I read the thread about power drop off at higher rpm--I think this is probably a gas flow problem (I think there's a baffle loose in the muffler), as the rest of the engine is fairly recently rebuilt.

Thanks in advance!
