Best v8 swap regal

[DRIVEN]

Thank you, I honestly wanna just get the thing running again a lot of sentimental value behind it

I 100% understand. I got my Cutlass from my grandpa too.

The Olds 350 would be the easier swap and offers a much better selection of long-tube headers.

 

[MrSony]

Yep, 350olds. By far the easiest in your situation. What transmission?

I can relate. My wagon has also been in the family since new, and has been very well-preserved.

The A/C brackets need extended for a 455. Everything will transfer over to the Olds 350. The 76 and older motors are better motors. A stock 71 to 76 should bolt in and even use the factory CCC 307 parts if they are still on there. If it is the TH200C trans, it is on borrowed time. It is the 2004R Overdrive trans, add the big Transgo kit with the billet servo and use the green TV limit and set the shifts to the firmest. The dual feeding option requires much more disassembly so I didn't use it. That and a bottom feed filter setup will help it live behind extra torque and will shift much better. Also at least add true dual exhaust as it frees up 20 hp/tq over the awful cross over and single pipe set up.

Olds 350 isn't a swap; it's a drop-in replacement.

Maybe he’s busy replacing his blown motor 🙂

Hopefully Frank, that Regal looks in pretty nice shape.

Yeah. It's a shame every minute that thing isn't on the road. It's like a Gentleman's GN.
