SLO247 1,713 Posted May 31, 2017 Here's another question. More for curiositys sake. Did the 302 and 351 use the same pistons? Were they dished? Just standard Falcon engines, not 4V or GT. Share this post Link to post Share on other sites
Mr Polson 10,214 Posted May 31, 2017 The 302 I pulled down had flat tops. Correct me if I'm wrong but the gudoen pin is at different heights between 351 and 302?Sent from my Pixel using Tapatalk Share this post Link to post Share on other sites
gregaust 319 Posted May 31, 2017 302 + 351 are same pistons and from original flat tops . The difference is the shorter stroke 302 uses a longer rod 351 = 3.5" stroke , 5.78" rod 302 = 3" stroke 6.030" rod 2 SLO247 and gerg reacted to this Share this post Link to post Share on other sites
Mr Polson 10,214 Posted May 31, 2017 Maybe it's 302 rods on a 351 crank that have the different pin height then?Sent from my Pixel using Tapatalk Share this post Link to post Share on other sites
SLO247 1,713 Posted May 31, 2017 Yeah that's right. Pistons to suit the longer rod on a 351 crank have a different pin height to drop the Piston down. Share this post Link to post Share on other sites

MNTL.XD 3,831 Posted June 1, 2017 I've got the 'special' ones, they make more power.(Runs for popcorn) heheSent from my SM-G900I using Tapatalk 2 Valvebouncer and gerg reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted June 2, 2017 Well they do use thinner rings, that's probably where the power comes from Sent from my CPH1607 using Tapatalk Share this post Link to post Share on other sites
