Windsor vs PCM

Pete, those are bmfrs, I bought a hit charger rt with the hemi, slow on the roll but after that the afterburners kick, all aluminum block, heads, real light, real fast, chrysler did a fine job building this one

Reid, I believe you are correct that Indmar built those Northstars for a few years for Mastercraft. They also currently have a 383 stroker (6.2 stroked from a 5.7) at 400 hp, which seems to me would be a torqier engine than a 6.0. And they made an LS1 for Malibu which was a very enxpensive Corvette engine that was light and fast on the top end, although interestingly, my friend the Malibu salesman told me they weren't nearly as durable as a 5.7. He said they didn't like to run WFO for very long. I guess they would burn valves pretty easily.

Speaking of Indmar... does anyone know what carb this is? It is a duel feed and seems bigger than a 4160. I haven't seen them in any Holley catalogs.

You guys are posting some great specs and info on here. You guys ruffled even the "Main Man".. Mr Lavine.. I am a Ford guy for marine, Chevy or Chrylser can not match what Ford can do with marine motors. My opinion though. The old style big blocks Fords where King, and think why have most of these new v-drives choose 6.0 vortec motors know. Malibu, and MasterCraft, i think put chevys in them know. I will stay with Ford in my boat..

Yes Lee, that is a good looking motor Bruce posted there, but I'm sure you'll agree that a nice 390 makes for a better viewing experience. I can't wait to see Bruce's 390. But wait, we're trying to sell you on sticking with a Windsor aren't we. Well with the valve cover adaptors, a Windsor can look just about like this 390 here.    

Bruce,
So you are saying the 351 can look like that one.. I wish! I love those 390's.. Love that interceptor..

Excuse me, I meant Reid..

pete,
lol.. looks good though if he did..

Lee, You're a little confused. It's Pete Brainard and his Grey Marine that used to cruise to Glenn Miller. That was way before Reid's and my time. 390's go with Beach Boys and the Daytonas.

Could be an earlier model or derrivitive of this, prior to the plastic accel pump levers...

Or it could be a 4160 with a rear metering block conversion kit. Looks the same on that side! The other side would show vaccuum secondaries (or lack thereof) and would confirm.

Bruce, the 750cfm and larger 4160/4150's have the dual feed like the carb pictured. We've got a 750cfm 4160 (converted metering block) on the BFN.

I don't have a picture of the other side, but wouldn't a 750cfm be too large for a 5.7 GM? I wondered if it was a specially made 600cfm for Malibu. The intake seems to be specially made as it has their name on it. I don't know if it's aluminum or not. They put a rubbery paint on their engines and cover everything up. I used to think those plastic Corvette valve covers looked good, but they're not nearly as good looking as those chrome ones on that 390.

Holley web site you'll see the 600 4150 is a dual feed

Tim headers?

Ahh, that must be it then. I didnt realize there was such an animal. thats probably what you have, Bruce.

Nice headers. We're looking for some for the BFN now... looks like those would have some motorbox clearance issues though!

Brian, Im not sure about the flange being backwards... I guess its possible if it came out of a jetboat or I/O instead of a v-drive. I hadnt thought about that before! Nice catch.

Let me know what you find out about those. Seems like a lot of the jet's and v-drives used dry headers (sometimes theyre "water injected") rather than fully jacketed like we would want. These appear to be the latter, while I think Bassets are generally dry or injected. I do think those look exceptionally tall though, and probably wont work for either of us... no motorbox clearance issues for the jetboat crowd!
