Now that would have been funny! I do have a set of glenwoods alum for 289-351 if anybody int. Mercruiser sent me over here sayed there was alot of h/m stuff.

jbear,
I'm stuck on the fence on the 70 Nautique. Once you confirmed it as a 302 H/M and not a 351, I lost just a bit of interest.

vrod, rest a$$ured that most folks on this site know what these manifolds are worth. I've got an extra two sets in need of some tig patch work I've been holding on to, and will probably be buried with them.

Regarding Holman Moody engines in general, I'm certainly one of the very biggest H/M fans and living in the vicinity of their origin and home base of Charlotte, we still hear a bit about them. There are however, a handfull of misconceptions that abound in regards to the engines that they provided to the OEM boat builders. Number one and foremost as much as it pains me, these were NOT special race engines and were simply a marinization pkg added to the longblock provided by Ford, typically using the same components as those Ford engines sold by Interceptor and MerCruiser of the earliest days, and later PCM and Wakesha(sp), etc.. BUT, during the late 60's and very early 70's, HM did offer the high comp auto-spec versions of those Ford base engines, namely in our cases the 235HP 302s and 290HP 351s. Guys check your bellhousing mounted I.D. tags which typically listed the comp ratio, which ranged from 10-10.5:1 on the earliest 4V 289-302s and 10.7 on the 4V 351s. After 1970-71 you'll see CRs listed as 9.5:1 or less or not even listed at all. Even in later engines when the CR dropped in line with the other OEMs, H/M still used the 235 and 290 model designations, although HP listed in the manuals was a bit less. But I'm not attempting to burst bubbles as again I'm the No 1 fan. What to me was more important and unique was/is: These neat alum header-style exhausts, alum bellhousings with rear engine mounts attached to them instead of the trans, allowing you to drop the trans without having to support and realign the engine (huge), crank-driven H2O pump, double belted pulleys on later models, and don't forget the factory chrome valve covers on nearly every one I've ever seen. Strangely though, while they were considered to be the hot ticket upgrade, every price sheet I've seen listed the H/M as being less costly than either a Chrysler, Palmer, OMC, etc. If you wanted to purchase an aftermarket engine directly from H/M you could do so, and get anything you wanted. They indeed were in the business to sell horsepower, racing and speed, and I've got a brochure from '68+/- which shows big blocks to 700HP. That's all I know.          

Regardless of The hp these are loud, that was my pointwith the skier comment! I'll stop bye from time to time and heres where I'm at www.nmxtreme.com

Thanks Paul. The 390 is unfortunately still stuck firmly to the stringers. Your rebuild schedule is making me look bad. I'll use your inquiry as motivation.
