Chelby-Ann 47 Report post Posted March 15, 2014 I bought new ceramic coated TRI-Y Headers for my 302. I know that most EM's need to be slightly modified to fit. As you can see from the pictures I have clearance issues. The headers are mocked up for now. What is the best way to get these to clear the bell housing and maybe the starter? I really don't want to beat the ceramic coating to make them clear but if that is the best way, what advice can you give? Can I grind away at the bell housing? Thanks for the help.

Rsanter 152 Report post Posted March 15, 2014 You can grind the bello using but that will be a ton of grinding. I suspect you have a later bel housing on there that uses the larger flywheel/flex plate like used for the 351c You can buy a spare header flange ( like to make headers) or make one and then use it as a spacer and use 2 gaskets to move the header away. I think/ hope it will still clear the shock tower if you do that Bob Quote Share this post Link to post Share on other sites
maxum96 32 Report post Posted March 15, 2014 That looks like a really poor fitting header. Even if you clearanced the bellhousing, the header is still going to be up against the starter. Not good. Quote Share this post Link to post Share on other sites

Chelby-Ann 47 Report post Posted March 24, 2014 Ceramic coated Peritronix Tri-Y headers from CJ Pony Model EXHD10 Solved my interference fit by grinding the bell housing down and now have a 3/16 clearance and I ordered a new hi-torque mini starter. No more interference fitment issues. Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted March 24, 2014 They must work really hard to have fitment issues with tri-y headers! There's only two tubes going thru a pretty large area on the passenger side. Last time I checked, ceramic coated headers were pretty pricey. You'd think grinding anything would not be needed. I know I wouldn't. Bob Quote Share this post Link to post Share on other sites
Chelby-Ann 47 Report post Posted March 31, 2014 (edited) I ended up removing the standard 4" starter, ground down the bell housing until I had about .200" clearance and installed a mini Hi-Torque starter designed to take care of these clearance issues. I did not have to beat down on my new headers. I also went with the locking header bolts from Summit. :thumbup1: Edited March 31, 2014 by Chelby-Ann Spelling Quote Share this post Link to post Share on other sites
