I'm running a bone stock 78 mofel 400, factory 2bbl isn't the best. A friend gave me a spreadbore Cleveland intake but I'm pretty sure the ports on the heads are much smaller than the intake. He swears he has ran it on a 351M and it worked great. Anyone ever encountered this?
I've heard it will work, with a #8053 spacer, but haven't bolted one on myself. Sent from my SM-G930P using Tapatalk
That's more than likely an aftermarket piece not made anymore. I've owned and rebuilt a 2v Cleveland, never seen the 4v Cleveland intake on a 400, but I've seen my step dad's 400.
Ha, found it ! #8053 is a !" carb spacer. EGR capable or looks like it can be blocked off for racing. Summit has it for $81.88 @Lunchbox213
Hi Lunchbox you need spacers between the head and intake, unfortunately they are no longer made (weinend made them). The deck width is different between cleveland and M blocks.
