HO cam, I guess with the 1.7s? That should wake it up a bit they make good power. I'm going to put mine together this week, painted the inside of the block last night, about to go and give the outside a hit of 2pack shortly. I'm using some AFR Outlaw alloy heads, and reasonable sized Comp Cam extreme energy roller cam with some Scorpion roller rockers. I've got a set of 1.7s comp cams rockers, from another engine, but the valves will be getting close to the pistons on this cam I think, and I don't want to move the power an higher up the rev range, I'll check the clearance when I build it, may try the 1.7s later for an experiment. Not running injection, but and RPM Air-gap and Holley avenger. Got some RHD Hedman ceramic coated 4 into 1 headers, from Sydney mustang supplies. Hopefully it will be a pretty twisty engine.
