Has anyone one the forum done this using factory style (Moroso) motor mounts?
What were the pitfalls you encountered?
Thank you

I have a customer that passed and left me with the parts and labor bill for a 565.
I can either sell the stuff or keep it for my velle and deal with some problems getting it into the car this winter.
I'd rather not use an engine plate unless necessary.

Are you sure it’s a tall deck? A 565 is easily done with a standard deck height block.

Headers and steering shaft would be your biggest issues.

Yes I’m sure
Headers: you absolutely NEED custom made headers, unless you want to ding the drivers side in 4 to 6 places to clear the floor boards, the steering shaft, and the frame rails, and possibly ding the passenger side in at least one place. I bought custom headers from Dan Lemons for my tall deck engine. They can be used even with the factory steering shaft, without having to "dimple" them anywhere, and you can go as big as 2 1/8" primary tubes while still keeping all for tubes inside of the frame rails on both the passenger side and drivers side, and still have excellent spark plug access, (IF you choose his "Touring" headers).And BTW, Dan is a great guy to work with, and he won't even need to kid nap your car for 6 weeks like some other header places will to make custom headers. After a short phone call, Dan will know exactly how to fab your headers.
Oil Pan: AFAIK, the Milodon 31188 pan, and the Moroso 21047/21049 are the only ones that will fit a GM A-body frame, without any modification if you're lucky, or with a little bit, and still provide enough clearance for the crankshaft that you'll need.
Steering linkage: Good luck. You're gonna need it. If you're lucky, the factory linkage will clear the oil pan. If not, then you can either "dimple" the pan in two places where the inner tie rod ends will hit, or you'll have to go with a rack & pinion set up.
Hood clearance: IDK how tall your "L-88" hood is, (BTW, I've never even heard of an "L-88" hood for a Chevelle, so you guys have me lost on that one) but if it's at least as tall as the factory cowl induction 70-72 Chevelle hood is, (which is about 2" taller than the rest of the factory Chevelle hoods) then you have a good chance to make this work. Even with an extra 2" hood clearance, this will be tough, but not impossible IF you choose an intake manifold that isn't too tall. I have found that you'll have two choices of intake manifolds... The Merlin-X single plane manifold,(has a 6.23"/6.43" height) (#063041 for Dominator carbs, and #063031 for 4150 carbs) and the discontinued Edelbrock #2911 Victor TD, (which has a 6.23" height). Anything with more than a 6.5" height is going to give you problems with the air cleaner to hood clearance, and you can forget about using a carb spacer.

its not that hard to do. just took a 580 out of my 69. merlin single plane with 1050 cleard the stock hood. no room for air cleaner though. same stock mounts as the 454 had.
oil pan was a champ pan no issues with steering linkage or frame issues. same headman headers the 454 used. no beating them up. they were tight though. had to work hard to get a gasket in between head and header. they were a small 1 7/8 tube so that helped im sure.

Uhmmm....so you ran your car without an air cleaner? Don't think I'd ever want to do that for anything other than maybe a 7 or 8 second dyno pull

I doubt I’ll have a hood clearance problem.
If I had to would a taller saddle mount help?

The L-88 hood was a really popular mod in the 70's and you might find one on a Baldwin Motion Chevelle or just as a day 2 option on some hot rodders Chevelle.They were sold as full fiberglass Chevelle/Camaro/Nova and of course Corvette's hoods or as a fiberglass hood scoop that people added on to their steel hoods.IMO the L-88 hood on a 69 Chevelle is one of the better looking hood scoops available for them.
One of our members added one on a V8 Vega some years back and it came out great looking.I'll add a link when I find it so you'll know what it looks like.

Like Billy said, make sure you think about the oil pan. None of my 4.25 stroke engines were "happy" over 6500 with stock type pans. They ran and I personally never saw any damage from it, but you could see oil pressure fall off when it should have been increasing with rpm. More than likely aeration of the oil due to the short front pan section. the 21049 Moroso pan was the only one I had that stopped this.
