I inherited a 400M bored .60 It has 351 4V cleveland closed chambered heads. Very high lift cam, (don't know) all roller motor, no expense sparred, "had" a 6-71 BDS blower w/ 2 -500 edelbrocks, ONLY FOR LOOKS, was in a show car. 13:1 comp. or close to it. very little boost, custom spacers were used against heads for blower intake fitup (did a good job). I'm told a 351c intake will work with the spacers. or 400 without, I'm not sure what to use for an intake. I would like to leave the spacers just because of the trouble somebody went too. I was told the engine was built to the #$%uts! I wish I had a little more info on the engine specs. I wanted to go dual carbs, obviously no intakes for these. I'm not necessarily going to race it, but would like something that will work descent. Any suggestions, or will I have to pull this motor down to see what I've got?
