I'm just picking up a 455 big block... right know i have a small block in there.. my question is other then the headers what else do i need to do to put this motor (F396021 with g heads) in there. Will i have clearance issues anything i need to move around... Can some tell me what i need to look out for???
Thanks in advance for the responses..

 

Well I can tell you use the same mounts that are on the 330 and the water pump, brackets and pulleys as well. Not sure about any clearance issues as you could get a BBO in that car soo....

 

should drop right in!

 

The car has a 283 chebby small block do i have to get different mounts to drop it in?? what kind of headders did you get for yours

 

You will need the correct 64-67 Olds frames mounts and you should be good to go after that.

 

Thats sounds great... This engine came complete with everything.. someone mention to change all the brackets and stuff... should i do this or leave it all it came with and freshen it up....

 

I'd be interested in the chevy mounts when you get done....

 

You're also going to need a different transmission and most likely driveshaft.

 

Sorry did not realize you had a 283 in it?? As the others said, you need the correct frame brkts and motor mounts for the 455. If yours has all the accessory's and brackets just use those!

What trans are you currently using? The chevy trans will not work directly with the olds motor? I believe your starter wiring will have to be rerouted to the other side also.

 

This setup came with the 455 motor and 400 trans together and i also got the yoke for it and the radiator... Just pulled from a working car...

 

Then it should be rather easy!

 

Im just tring to see what i am facing to see if i needed to look out for something from everyone's else experience...

 

cintr113: This sounds like a great project! I don't have anything else to add except to say, we would love to see some pictures!
Good luck with your engine swap.

 

Thanks i will post before and after pictures...
im considering to do some sprucing up... and take it apart before i put it in so i can get more power out of it.... will keep all of you posted

 

Ok I'm ready to do the rebuild.. I want to do something a little better then stock.. Something like mlld. Nothing to crazy.. Not too much money either but will do what makes sense. Please give some suggestions so I can resaearch and make a decision on the recommendations. Thanx

 

There are several threads related to mild to wild 455 builds in here! Even just a stock 455 with that trans, a set of headers, good carb and manifold, will be a dramatic improvement over what you have now.

 

Ok project is finally almost done pics are coming soon. I have a question. What headers should I get for this setup. Thanx

 

Cool, fill us in on what you did, and would love to see some pic's. Any brand header should work well with your 455.

 

Yes but I hear that most of them don't fit right on the 1966 f85. Any suggestions

 

Buy Hookers that fit a 66 442.

 

Does it make a difference from a 4 door to the 2 door. Because I have a 4 door. Do you have a model number from hooker by any chance

 

The passenger side sometimes needs a bit of massaging sometimes with any brand. Does not matter about how many doors the front is the same.

 

Thanx. I will post pics and tech info soon

 

If you need the frame side of the mounts I have those available. Also can do the Chevy mounts for whoever was looking. Just drop me a pm or email

thanks
