[BaRoN vOn BuIcK]

I have a 1984 Regal and i want to swap the engine but i'm not sure which engine would fit in there nicely or be the best to swap in there, 350? 455? so please just give me your input and exactly (if you have time) what i would have to do for the swap. Thanks all!:Dou:

A 350 Buick engine would drop in with almost no hastle. The only difference I think might be the fan shroud depth. With a 455 I think you will have heater/AC clearance problems that need to be looked at.

Dazed and Confused,

350s fit really nice with several parts from the V-6. 455s take more work, but the power would be nicer. If you are on a tight budget like me, I recommend the 350.

Ok now someone mentioned on another forum that i would have to change the whole suspension with the 455 swap now if that is true does that also apply to the 350 swap?:Do No:

You'll want to put V-8 springs up front. Thats all. Mine still has the V-6 springs. Handles BAD.

If i put the 455 in my regal is that all i have to do is change the springs or is there more to it? Also

WARNING WARNING! Very petty readable material ahead!

My friend has a 87 Gn mostly stock alls he does is flap his gums about the car "my cars fast, i beat this i beat that.....etc...."
If i swapped the 350 in with some other work on the car can i make him eat and choke on his words?

END OF PETTY DIALOGUE!

What is a good tranny and rearend combo with the 350 and or 455?

Thanks all
Patrick

P.S. Me and my friend love to out do eachother!

Your goal of beating your buddy's GN is a lofty one.
It would really depend on what you can afford. Best speed for the buck is a Big Block. A 350 will need built up to take on the mighty turbo Regal. I guess a built TH350 trans is your best bet. Those who know say the TH400 use's up to much power.
The factory 7.5 inch rear is weak. Turbos used the beefier 8.5.
Aftermarket companies make Ford nine inch rears that will bolt in. Those are pretty darn strong, but expensive.
If you can afford all the top of the line stuff, consider just buying a decent T-type instead. However, in my opinion, the reason we put the V-8s in is cause we can't afford GNs.

I've always wondered why the gear ratios in the TH400 are different than the TH350...the 400's gears rob you of power.

2.48 as opposed to 2.53 (?)

To swap the 350 in place of the 231, use the 231 rubber motor mounts and the motor will drop right in place...All the 231 accessories and brackets will bolt right on...Use a radiator from a V8 Regal...New aftermarket radiators are less than $150...You will also need the upper radiator support for the V8 radiator...I think they are still available from GM and not very $$$ either...Or get one from a salvage yard along with the V8 fan shroud...Other than that, it should be a fairly simple swap...

then all you need to add is a pair of turbos on that 350 and you'd be beating that GN in no time.

[BaRoN vOn BuIcK]

Pair of turbos?

[tlivingd]

yea you have 2 sets of 4 cylinders. so twin turbo. comon man work with me here. yea there is the small problem with the common intake manifold but thats pretty easily over come.
