[QUOTE="rlepecha, post: 584740, member: 19679"] Surely if that's the case, the OP with a 1641 + 34 ICT's won't be far off 70-75 HP also? Might need a better exhaust if still running stock, but that's about all? I've not done many more changes than the OP, I've only got 1.25:1 rockers because I'm using 33/30mm small valve Mexican EFI heads at the moment so will most likely be loosing power to those on something more stock, 35/32mm or similar. My concern for the OP would be it could cost somewhere upwards off £400 for a rebuild of his 3rib, but a decent 6rib on eBay wouldnt cost you much more. [/QUOTE]
