Which am I better off using. Experiences? Stock 400 rebuild.

I'm going with a cast iron '66 spread bore to keep the stock-ish look and run a Quadrajet or Holley (haven't decided yet).
The Olds specialist that worked on my 400 block said the stock 400 with the 4GC tends to run lean and needs more fuel. Might contribute to the heat issues as well.

I'm guessing you don't want the divorced choke anyway. |

I'm guessing you don't want the divorced choke anyway. I like that idea, too. For my car, I'm too far down the first path though. '66 manifold is already painted, installed and the engine started. |

One thing I will tell you about using a Performer over the stock manifold.....the front end of the car will rise about a foot from the deletion of all the weight!! I put a Performer on my 455 ('76 Toronado motor) in my '65 with a 660 Holley, and it runs great. Plus I got rid of all the crap that was on the stock manifold. I had originally bought a dual plane manifold, but couldn't get the hood shut.....without a carb!! I didn't want to cut the hood, so I ended up having to mill about 3/8 inch off the carb base, use a dropped breather and a 2 inch air cleaner to get clearance between the breather and hood insulation..

What mounts are you using?
I had a Performer, Holley, and a 14x3 air cleaner with a drop base and it fit under my stock hood.
I guess I am confused because a Performer is a dual plane manifold.

When I drug the car out of a salvage, it had chevy mounts in it, so I used the 400 mount brackets from another '65 donor 442 and 400 motor mounts, really don't know if those mounts position the motor higher than different ones or not. As close as the starter was to frame, etc., mounts that were lower would have caused problems in r&ring it. The performer I have isn't a dual plane. Can't tell you if Edlebrock makes both or not.

Not sure what you are calling "400" motor mounts, but for 1965 the frame pads and motor mounts were the same for both the 330 and 400. Commonly available Anchor 2261s would be the correct rubber mounts for those frame pads. |

By "400" mounts, I meant I went to my local AutoZone and bought the factory mounts they carried. I don't know if there is an aftermarket mount a person could buy to use on the 455's in '65 cars. I can't tell you offhand if the mount you spoke of were the ones I bought or not.... I bought a dealer's racecar in '65 and don't remember having any problems with clearance, but it also had the cast iron manifold with a Holley, and it used the '442 cleaner.

Nearly every catalog lists Olds motor mounts incorrectly - even big name Olds specialty vendors. Bottom line is that the motor mounts need to match the FRAME mounts, NOT the block. All Olds blocks (big and small) have the motor mount bolt holes in exactly the same location. The only difference in the blocks is deck height. Use 2261s with ALL 1964-1968 (yes, 1968) frame mounts, no matter what Olds engine. |

The frame mounts I used came from a '65 442 droptop which should have had a 400 in it. My car had been so badly cannibalized (and bastardized) that I had to use the droptop and a '65 Cutlass ht for parts to put it back together. Whoever had owned it previously welded (guess you could call it welding, and not pigeon shit) the rear trailing arms solid to the rearend with a plate on the backside....I suppose they thought they would work as traction bars. They had front end springs in place of the rear coils bailing-wired in place. So, pretty hard to tell what the car was supposed to be....definitely had a hard live. If it hadn't been a post car, I probably wouldn't have saved it. It did have the ID plate on the firewall tho, amazingly.
