4k block with a 5k head in my Rolland.
I took the head off the block a week ago to port and polish the head etc.
When I took this head into the shop,the man said it is a 5k because it has small combustion chambers.
Ok so from what I have heard,the compression this would be making may be WAAAAYY to high?
QUESTION: WHY DIDN'T MY ENGINE RUN LIKE A DOG? IT DIDN'T EVEN HAVE THAT BARK TO IT LIKE A HIGH COMP ENGINE,AND IT DIDN'T SLOW THE ENGINE FAST WHEN OFF THE ACCELERATOR (like my old 4 with 3k head used to do..
WHY IS THIS ENGINE RUNNING FINE?
Is there some way that the cam,or over sized bore and pistons are lowering the compression enough?
Ok so my specs are:
The crank wheel,when all pistons are at TDC,the crank pulley has the 0 mark about 9 o'clock in reference to the TDC on the block...could this be why??
*Lumpy as cam,very lumpy and boggy down low,unknown cam grind,..much to my disgust...
*2 inch exhaust
*ported and polished head by myself (guy at machine shop says he was au rises how good it was from me being a novice,..took me 30 hours.
*matched the ports to Manifold
*40 thou over sized pistons ( so it's bored out slightly) FLAT TOP"
*5k dizzy
*extractors
*Weber
*normal head gasket
*standard valves
I JUST DO NOT KNOW THE ANSWERS????
HEEEEEELLLLLLLLLLLLLLLPPPP PLZZZ GUYZ :)}{ :(
