d510addict Posted February 5, 2011 Report Share Posted February 5, 2011 Hey all I have some stuff to put a engine together but I have a few questions. The head I have is an a87 head and a l16 block, the block is currently board thirty over but the pistons were very damaged. I was thinking of boring out that block to fourty over and use the a87 head on it. Where would you recommend to source the parts and is there a reputable machine shop in the Portland area that any of you would recommend? Do you have recommendations for the pistons? I have 2 of the a87 heads 1 has peanut shaped chambers, the other has round ports with a slight peanut shaped etched inside of the dish. What one would you recommend? I know there is a problem that may come up with too high of compression which is mainly why I am posting and I know there are links for calculating compression and what not but some of the math would be hard for me to do as I do not know the specs of these heads and one of them has had previous machine work done to it but I do not know what was done. One last question, what would be an ideal compression ratio for a higher performance driver? As I want more power out of the l16 but need it to be drivable everyday. Thank you everyone and have a good weekend. Quote Link to comment
