Sno 15 Posted April 12, 2015 Out of curiosity does anyone know if you can fit a C4 in an XM without having to make major changes to the firewall/trans tunnel? If not what other auto would work behind a mild Windsor? Cheers Share this post Link to post Share on other sites
Olive Xm 34 Posted April 13, 2015 I helped remove a c4 and 302 w out f an Xm then we replaced it with a c9 and 351w. Fitted easy but the trans crossmember was already modded. Pan fill c4 (c10) probably won't work due to the rounder front. Stay 157 tooth fly and you won't have a problem. 2 Sno and steve mcqueen reacted to this Share this post Link to post Share on other sites

ando76 4,354 Posted May 18, 2015 just saw this thread. My c4 bolted straight into my Xl falcon with the Castlemaine Rod shop x member. Share this post Link to post Share on other sites
Sno 15 Posted May 19, 2015 Thanks guys. Hoping to have my XD sold this weekend so I have the last few $$ needed to go pick up the XM Futura Hardtop Ive put a deposit on. Will be a loooooong term project but Im cruising around building ideas for how I want her to turn out. 1 steve mcqueen reacted to this Share this post Link to post Share on other sites
