Novice with a question

[Rock]

Hi new guy here , I have a little blandit 600 project. I have bought a 1990 gsx750f engine for it. Is it worth fitting gsxr cams to it before I do the engine swap? If so what year cam's will fit and what gains would I get?

Thanks for any help

Welcome Rock. With the Teapot engine, you have a good start! It's got the 'Dot' head. Cams as std. are ok, but you'd probably benefit from fitting GSXR 750 cams from '88-'90. Run the engine as is, and see what you think.

Hi bud. Welcome to OSS

I think he means is it worth putting the 750 cams in the 600 engine first rather than just swapping engines.  In a word - no.  Probably.  There is no substitute for cubes so in general getting a smaller engine to shift more fuel and air is only worth it if you are restricted by capacity.  You might well get more gains by adjusting the cam timing and phasing with the 600 cams than going to 750 cams.  I've done camgraphs for a few different camshafts and they are not that different to each other apart from the set of regrinds I have which had more lift and a touch more duration, but the engine didn't need more lift or duration to operate in the region we needed it to. Standard cams are quite good.

so the concensus is then that there's not much to gain by cam changes on the 600 teapot motor? I have a 95 teapot (love it to bits, the old heap) and wondered if there was any way to get more from it...
