Jay762 Posted March 24, 2020 Share Posted March 24, 2020 the majority of blocks that come as standard are not good for big HP builds - The exception that is the early closed deck blocks (CDB). You will need to decide which route to go as the internals will vary accordingly. The pretty much undisputed best build solution for these motors is the 2.0 cdb block with a 2.35 stroker kit. However doing a cdb conversion on your block then using standard sized forged pistons (look at Mahle 2618 race pistons) with arrow rods and associated uprated bearings (Cosworth, King, Mahle) will get you to a 550 capable build. You will also need uprated bolts - ARP is the norm and uprated head gaskets, RCM ones do not need reaming if you are going for a 14 / 14 size thread conversion. Heads. Your standard heads will be fine from a sizing perspective however your will need to look at changing the springs & retainers - look at supertech or RCM. Talk to these guys - in your part of the world and can sort your cdb conversion plus build parts http://asperformance.com Quote Link to comment Share on other sites More sharing options...
