Have a low mileage HP motor i picked up from a mate and I've been collecting a few bits off Gumtree to throw together a warm street combo for my FB ute. I am sticking with the three speed crash box as the floor is too good to cut and I want to have original floor covering. Currently has the 3.89:1 diff but will no doubt go taller depending what comes along. I do have a few 3.08:1 centres lying around in varying condition and will try and run as tall tyres as I can.

Parts I have accumulated are WW carb from a 253 HQ manual, on factory WW manifold, X2 headers, 186S headers, 6° Bosch electronic dizzy. Original head just needs a lap or I have a stage 1 YT spec 202 head I picked up. Non adjustable rockers, double (dampeners) springs, big inlet valves, port and post job.

Picked up an unused Dynotec CM205D cam for $100. I am thinking to use this cam with the worked head but concerned the lift may be a bit taxing. Advertised at 429. I really wanted something a bit milder like a torque economy grind just for a bit of a lopey idle. Something that would work with the stock head even.

Any advice gratefully accepted red six gurus.
Cheers

Thanks Rob. Yes I've read a bit of his stuff. Will revisit.

According to old Jonno’s specs my cam is right in between a mild street cam and slightly warmer with lumpy idle. My main concern is coil bind at 0.429” lift. I hope the modified head has had longer springs installed with seats lowered and/ or offset retainers. I suppose I should be able to compare to my standard head. Ultimately I will dummy assemble and turn by hand I suppose.
