Welcome to M&M Richard!  Glad to have you with us. What intake do you have RIch? Is it for a tall deack 351M/400? I have some experience with some 427 inch 351 stuff and I will try to help you the best that I can.  Alex------------------

Alex,Has anyone ever made a single-plane for a 351M/400? Just curious, as I've never seen or heard of one. ------------------

If that's a 351C intake, you are out of luck.It won't fit the 351M. ------------------

I; myself, wouldn't try to do anything with a 351M/400. Since there are so many good Clevelands still out there (if you want a standard displacement), and since 427 cubes are a call to PAW away for a Windsor (and considering the wealth of performance parts for the Windsors) there isn't much need to hassle with the oddities that a 351M/400 brings. IMHO
Unless you just want to be different... Which is more than OK by me. ------------------

steve& thud thay don't make intakes like I was refering to for the 400m,but there is I beleave two places that make adapter plates. I hope you geants can bear with me, I am kind of new at wrighting post. The last time I wrote any one was when I was in the servise and living in a country no one would rather take about. Lets get to the point. I have been cheaking out stroker engines like the 302&351w for a few years. One of the things I notest is when ether one of those engines are stroked to the upper limits the ring package and skerts become small.I may be wong but dosn't this make the durability go away? If you were to stroke the 400m to 4.25 it would seam to me you would have a good ring package left. On my secound point I will have to use an exampl. It seams to me when the boss 429 thay didn't quite live up to it's expectations. And then some one stroked this engine to 500 c.i which made 71c.i. pull more air though the big intake ports which made a higher valosity.I beleave with a 4.25 stroke on the 400m the cubes would be around 430 something and the differance in cubes compard to the 351 c is around 80 which seams like an even faster valosity. I may be rong but other then the expence this could be a killer engine. Sorry for this being so long I tried to compress my brain but it hurt to much.thanks for hearing me out Richard.

I would like to see a motor like this. Alot of people talk bad about M's, but I don't see whats wrong with them. Same journals as a windsor, long rods, 2v cleveland heads. Stock sucks because of low compression and 2v carbs, but I think they would have potential though.------------------

Hey RIch, tell us more about the 68 Cougar GTE. Is it a "W" code by chance? Hmmm?  Alex P.S. I'm working on the 400 solution for you. ------------------

Thanks for your help Alex and congradulations on being racer of the week. The GTE is a W code. It is also a xr-7. I had it in a show a couple of times,but the real fun was putting around on the street looking for the enamy. Yes I am a 53 year old punk.

Thanks Rich for the compliment. No back to your original questions. Edelbrock does make a pretty decent Performer for the 400M motor. This combo would make a pretty good torque monster but would not be very happy much over 6000RPM. The piston speed is way high and rod breakage becomes a problem. That's what happened to the one that I was involved with, we tried runing it at 7000+ and it kept breaking rods near the pin end. It's a fairly economical venture if you have access to a good machine shop and many stock parts can be used. I would recomend low compression also if you want to persue this combo. The heads suck too by the way. I have to agree with thud though Rich, that a 427 inch 351W is a much more viable and proven performance package. Many more parts are readily available for the 351W than the 400M. Also the Boss 429 more than proved itself at it's original size on the Nascar tracks. The detuned hydraulic cam street versions were the duds. That's why they never were any good in NHRA stock or Superstock. They would fly now with todays rules but due to their value it would be cost prohibitive to build one. And to answer your question Thud, Offenhouser mad a Port-o-sonic for the 351M-400 for a short time in the 70's. Alex------------------

Gee alex I was kinda hopeing the 4000m fell into the same class as the week and unreliable C4s,AODs and 8in. rear ends. I was'nt planing on twisting the combo past 6500. Dose any body know what kind of RPM the 454w strokers are turning.
