imtb Posted January 25, 2010 Report Share Posted January 25, 2010 After two hours of wiggling, pushing and cursing i got the LZ2.2 installed. The exhuast is hitting the on the down pipe. It didnt hit on the L18 I took out. I slotted the motor mount holes and so I have some adjustment. The oil pan is not hitting the x-member. Any ideas how to correct this/ I am going to try some ehaust hanger and pull it over to clear. Just need some carbs and I'll be ready to fire it up! Quote Link to comment
datzenmike Posted January 25, 2010 Report Share Posted January 25, 2010 The Z22 block is 2cm taller so the head (and exhaust manifold) is 2cm higher as well. Quote Link to comment
imtb Posted January 25, 2010 Author Report Share Posted January 25, 2010 Hey D Mike, thanks for the response. It is still a L20B block just bored and Z crank. I guess the L20B is still 2cm taller causing the exhuast pipe to hit, guess I use the exhuast hanger and try and pull it over. Quote Link to comment
Jesse C. Posted January 25, 2010 Report Share Posted January 25, 2010 Yes, the L-20B is taller than the 16 and 18. Hence the extra bolt on the timing cover. Time to switch to a header! :D Quote Link to comment
hang_510 Posted January 25, 2010 Report Share Posted January 25, 2010 It is still a L20B block just bored and Z crank. I guess the L20B is still... ... a stroked L20b, not an LZ2.2 franken motor Quote Link to comment
moparvwfreak Posted January 25, 2010 Report Share Posted January 25, 2010 when i did my L20 swap, i used the same manifold and down pipe you did. i ended up doing a little hammer tuning to the downpipe so it would clear. and it worked and you dont even see where i had to hit it. cheap way to go.
