Title: Grey motor rebuild Post by: Johns on October 14, 2005, 08:56:59 PM Hi everyone,
My apologies if this has been covered before. I have an EJ with a tired grey. I thought I might rebuild it as a warm one with period gear. What would work well? Doesnt need to be stressed or cranky. I am thinking twin carbs (what type?) higher comp pistons, ported head? balanced, extractors. I just want a bit more urge so she can better keep up with traffic and cruise a bit easier. I want to retain the three speed, front end etc., Hope this hasn't been asked too many times before! What are your thoughts?

These are the mods I did to my 138. The bottom end was fully balanced, 40thou oversize pistons fitted, the head was decked 40 thou, ported, polished and port matched to manifolds. The valves are s/s red motor and the valve springs are 350 chev. The cam is a mild one from clive cams, i can get the specs for you if you like. I'm running twin carbs (stromberg) and extractors and a 2 1/4" exhaust. As far as performance goes, the car has 100 rwhp, it will idle smoothly, doesn't get hot and hasn't lost too much torque so the 3 speed works well with this combo. Hope this info helps you out Cheers Jason |
