Hi every one I'm the newbie lol

If you are planning to turbo, you are better off with stock or slightly longer than stock rods anyway. I would not use 200 rods, the benefit of the longer rods is for NA applications. There are pistons that exist for the AU rods that will work, but you will need to look. Just make sure the rod length + piston compression height add up to the same value as it does with the stock setup. If it is price that turned you off of the Spool rods, forget about 300hp NA + more later. If you have never driven a near stock crossflow and a decent sized turbo (say GT3582R) running 8-12 psi boost, you should try that first before committing to this build.

Check the block hasn't been shaved as well as this will increase the comp way to much for pump gas. I had a 351 030 (Block deck to 0) and CC Heads and it was a pinging nightmare with unleaded, even 98 was only a little improvement. Change to a wilder cam made a little difference but it then suffered on take off, increased stall and that helped but was still not fun. We estimated it had 11.8:1 comp as on Avgas it was a weapon, you could advance the timing from 0 to about 10degs and the change was awesome Mate had the engine after me and he replaced the heads with a set of shaved & Ported OC reco heads and back to the original Crow cam and it was a total different beast, no over heating and ran really nice as that was just over 10.3:1 compression

Yeah, tell em that won't fly with the concours guys.

False Dave. Century are the only company that make batteries in Australia, but they also make quite a few batteries for other brand names. Both SCA and Repco batteries are Century, mostly Aussie made batteries in different coloured cases with different stickers. And correct on no battery to suit X series - they no longer provide holes in any of their terminals.

Yep with a stock valvetrain, just a decent set of valve springs, decent head gasket & fresh bottom end. Stock CR is perfect for a turbo.
