So I been workin on the orangecrate off an on for what seems like forever... seems I now have rod issues. Knock knock.... Any way I'm lookin at building a motor, or rebuilding. Inexpensively (IMG:style_emoticons/default/lol-2.gif) I have only 2 real conditions I want to meet. 1- It will run 80 mph all day thru the desert in the summer in Phoenix and sit at stoplights with out cooking itself. 2- It will pull the 6% grades that you hit leaving the valley at 70 in the summer without cooking itself. 75 would be nicer. Guess I"m talking a torque motor. This is a stock 72 with stock gearing. And maybe one size up tires. Did I say it needs to be reliable? Like Phoenix to Portland and back any time of year reliable. And inexpensive.. I'd love to buy a Raby motor but $$$. Oh yea. I will be doing the assembly myself. And I'd like to use as much of the 1.7 as possible if possible. Thanks for the input. Build away.

Do the 1.7 case spigots and heads limit cyl/piston selection?

Do the 1.7 case spigots and heads limit cyl/piston selection? Only to the extent that 1.7L heads have smaller valves/ports and will limit airflow. Machine work can fix case/head fit. I built my original car's engine from a 1.7L and at the time I couldn't afford 2.0L heads. I went 96mm flat top pistons, carbs, performance cam, and had the 1.7L heads fly cut to accomodate the 96mm cylinders. The engine never really achieved it's potential from the displacment bump due to the heads restricting flow and my running stock heat exchanger pipes (minus exchangers for weight reduction (IMG:style_emoticons/default/lol-2.gif) ). Upping the compression ratio helped. Better than what I had started with but certainly wasn't Raby HP (IMG:style_emoticons/default/smile.gif) Per Mark Henry's note. Budget really needs to be known. I had sort of assumed that best plan would be to source fresh 2.0L AAP heads from HAM but those alone are $1700-1900 per pair (with aforementioned coatings) so may not exactly be "cheap" depending on OP's point of view. |
