Hi Andy thanks for a great range of videos. I'm building a ford 351 Cleveland with m122 at 5psi, running a ms3x. Fitted with a tow style cam , 1500 -4200rpm range. Will spend most of its life 1500 to < 3000rpm. I was thinking of MAF, but after watching your vids thinking I might be better off going speed density. Would value your input regards Rob
