1592 Top End Build
Posted: November 7th, 2009, 4:04 pm
I am finally getting around to putting together the top end of my 1592 that I bought from Don T a few years back. The block has 9.8 to one pistons, balanced rods, 80.4mm bore, fresh polished and balanced crank, rings, NOS quality bearings all around (Std), pinned crank and a crank scraper.
For the head I have a 1756 which has been previously ported and matched by Ray Mortensen out here in the NW. Intake is matched to the head with an 80 grit finish throughout. Carb. will be a 34/36 DFEV and ignition is a Crane XR700. Exhaust is a 4-2-1 stock set up.
Where I get a little fuzzy is cam selection. This will go in a 76 Spider that is driven mostly around town, so drivability is a must on pump gas; premium is fine, which is about 92 Octane out here in the NW. I don’t want a lumpy idle that shakes the mirrors at lights!
After reading theories and thoughts from so many on various forums as well as this one a mild increase to the intake seems to be a popular choice. I would also like to get adj cam pulleys so I don’t have to compromise on timing anymore. I doubt either the head or the block have been machined enough to really get the timing off but it’s nice to know for sure!
Looking for suggestions on a cam selection, NEW adj cam pulley sources, and flywheel /clutch selection as well. I know the 1592 employs the 10 MM bolts, so I will need to source a 1592 fly wheel. Any other thoughts are welcome that would help me optimize this motor before it goes in!
Thank you
