289 engine questions.......

[FFR428]

Hello everyone and Happy Holidays. Been a while since I've been here. But the Donzi bug has stayed with me and I've been looking again. I have a few questions about some of the original engines used. Some of the mid 60's boats I see came with the Ford 289. Were these really from Holman Moody marine in Fla? And what version of the 289 were they the solid lifter hipo engine or hyd lifter engine? I see they exhaust manifolds have the HM logo cast into them but don't know if Donzi just bought parts or entire engines from HM.

Also were the 302 ans 351's ever used in later years or were they Chevy power?

Thanks and hope everyone has been well.

Glenn.

Don't know about other Donzi's but I have seen mid 90's 16's with the 302 V8, which in stock form wasn't much faster than the 4.3 V6 with 4barrel, actually HP is virtually identical, and of course the V8 used more gas, BUT oh yassss, it sounds good with straight exhaust! :nilly:

[Donzi Vol]

Yes and yes. The original 16's and 18's from the late '60s came with 289 H/M motors, hense the blue exhaust logs with the logo. The 302 and 351s either came a couple years later or were an option. I'm sure that will be cleared up shortly.

Tom Smith's 1968 18 has an original H/M 289 that runs sweet and has some nice power for its size. My 1970 18 has an original H/M 351. I haven't pushed it just yet, but she's got some very nice power (revs up very nicely).

The chevy's came a little later in the game, but quickly became the standard.

Hope this helps. What are you looking at? Any boats in particular? :lookaroun:

All the best,
David

Thanks for the info everyone. Nothing in paticular has popped up at the moment that I'm looking at. So I'm just doing my homework finding out about everything I can in the meantime. A few boats I looked at still supposedly had the original engines and some were repowered which is fine too.

Think of it this way.... Ford released the 302 to the public in late 1967. Once the change took place the 302 replaced the 289 so from say 68 on up there would be no 289's used by HM except for left-over engines.

The 351W was released in 69.

HM used the hi-po 289 for their marine engines, at least they call it a 271. There are a few ways to tell if your 289 is setup this way. the most notable being mechanical lifters and screw in studs in the cylinder heads. As well as the cylinder head casting numbers. The blocks were the same as every other run of the mill 289 but the main caps were increased in thickness for added stiffness and strength.

In the early years (64 - 66) you had Eaton interceptors (sbf's) and by 66 HM 289's. There were even a few "off the wall" power options.

Our 1066 16 had a 289 H&M but not the Hypo. IT ran well. When we re-powed with a 302 (stock) it was at least as fast as the 289 and a little faster-not much.

My '67 Ski Sporter, hull #420, came with a 289 Ford/Eaton Interceptor. Original ss# was EW92L732948.

Very good to know thanks. Pretty cool they used the 289 hipo engine. Did they ever use the Ford 427? Back a few years when I was first looking around there was a guy here who was selling a Ford 427 with most of the marine bits included. Said it was out of a old Donzi and someone had converted it years ago for the FE. It was a package deal and too much $$$ for me at the time. He said a lot of the parts were from Holman Moody.

Thanks everyone very much for all the info! Good stuff.
