Will an old Holly Street Dominator intake fit, with no mods, on a 1989 360 engine ? Thanks.

As along as the 360 is an la version. Magnum engines changed the angle of bolt pattern.
yes, it will bolt right on is the direct answer.
360's were LA's through '92.

Yes, basically I didn't know for sure if that year 5.9 was considered LA or Magnum. Considering buying back an '89 B2500 I sold a guy awhile back, just to use engine for a current project, but wanted to make sure my parts on hand will change over. Thank you very much guys !
Possihly a hydraulic roller cam LA, which were in 3/4 ton and larger trucks, ram chargers, and B250 and larger vans. The last '89 hydraulic roller LA I was into had a windage tray, and they came with high swirl 318 heads. The street dominator works well on a 318, but the ports "might" a little smallish for a 360.

So not all '88 to '92 360's had roller cams and the 308 heads ? I thought they did. I did notice on my Alldata info, that they list a light duty engine (185hp) and a heavy duty version (205hp). Any way I can tell without pulling intake, which is not possible before purchase in this instance. VIN engine designation ?? Sorry for all the questions, I am a RB guy.

Good thought, it is actually on a 273 with 318(??) heads right now. And a Thumpin' hydraulic cam with headers ! Ha-ha, I didn't build it, came in a '67 Belvedere I bought.
You can pull the distributor and look to see if it has the spider and dog bones in it. A bore cam that operates with a cell phone helps a lot. Yes, the HD version is the hydraulic roller. The 308 heads, windage tray, and hydraulic roller are part of the power improvements, but they also had less restrictive emissions requirements.

Good idea, I have a fiber optic scope.
Being a B250 it should be a hydraulic roller engine. But I have seen several rebuild/reman engines that had the hydraulic rollers replaced with hydraulic flat tappet cams.
I have an late 91

Well, you appear to be in Florida and I'm in Ohio, so unless I drive down to see my uncle in Ft. Meyers, that ain't gonna work. I am curious though, what do these engines go for ?
