Whisler Posted January 10, 2021 Share Posted January 10, 2021 Hey, thank you. If I keep the Edelbrock, I'll take you up on that offer. Just let me know. Link to comment Share on other sites More sharing options...
BigBrother-84 Posted November 9, 2021 Share Posted November 9, 2021 You should be able to tell from the VIN, which shows on the Certification Label on the driver's door jamb. The 8th digit gives the engine code, with a G indicating a 351W 2bbl and an H representing a 351W 4bbl. Hi Gary, In BigBrother, the motor is not the original one (I swapped it around 2013, was rebuilt in 2015). It is a 351w 4v. Went to NAPA Auto Parts in order to renew distribution cap and rotor, the guy asked me if "code H or G". Since the motor is a replacement one (and the VIN certainly went out during the restoration), can I assume that a 4v is necessarily a Code H? Thanks!

HrdAngln Posted November 11, 2021 Share Posted November 11, 2021 Welcome, Steve. I actually have the same question, but I have a 400M. I was thinking of maybe getting the manual choke edlebrock performer. If anyone has suggestions, I'd appreciate it. - Jason Link to comment Share on other sites More sharing options...

I was thinking of maybe getting the manual choke edlebrock performer. If anyone has suggestions, I'd appreciate it. - Jason I ran an Edelbrock intake and 600 CFM Performer carb on a warmed up 351M and it ran great. All the carb that engine needed. And I ran the same carb on Big Blue for a bit and it worked fine, but the 750 CFM has more high-end power so that's what I'm running. I think a 600 is probably adequate for a stock 400. (There's no "M" on a 400. There was no other 400 so Ford saw no need to add an alpha suffix for it like the did with the 351's.) Link to comment Share on other sites More sharing options...

If you daily it and don't care about power get an Edelbroken, if you like having adjustable everything and don't mind playing with said adjustments and want max power go with a Holley style carb.

And I prefer anything but a Holley. I've had way too many power valve, accelerator pump, and bowl gasket problems. So I like the set and forget approach that the Carterbrocks give for anything but racing. However, if I was racing I'd probably go with a Holley. On carb sizing, the Holley 4180-C that Ford used on the 302HO, 351HO, and 460 is rated at just 600 CFM. And while I'm running a 750 Eddy on Big Blue at the moment, I did prove that he'd run just fine with a 600 CFM Eddy. In fact, the only difference I could tell is when he was winding up, and there the 750 had a bit more. Link to comment Share on other sites More sharing options...

As I stated earlier in this thread, I really like my Edlebrock 1406. It's been a great carb, easy to work on, reliable, no issues. As the AVS version has annular discharge, I wondered if my 1406 could be converted to annular discharge. In a web search that lead me down many paths, not finding what I was looking for, I did stumble on an interesting option in the Summit M2008. This was originally developed by Holley but then dumped for a few reasons and then picked up by Summit and modified. The reviews on this carb are very good and it has a lot of nice things about it including annular discharge. Yes, it still has the old power valve for which many complain about, but for some that is just not an issue. Based off what I read, if I were looking at purchasing a new 600 CFM carb, I might just take a chance on this. https://www.summitracing.com/parts/sum-m08600vs Link to comment Share on other sites More sharing options...
