So my question is how can you tell when you want a new engine because when i ran o.s. mine had almost no compression and still ran strong. Also whats ur input on a pinch and who do you prefer? I heard good from speed shop and alot of locals use rayaracing and love it, but how long will the pinch last i hear a gallon then i hear people say 4 to 5 gallons?
Thanks for the help: Gage
i know some people in my area that get Alan Burton to pinch their engines and they are getting 7-8 more gallons out of it. one guy in our area gets all of his engines pinched after 8 gallons then gets another 8 or so gallons out of them, the puts a new rod in and re-pinch and get another 4. he said he has done it to 3 other engines. all done by Alan Burton. i have only gotten one engine re-pinched and it was like new.
