John, you could always change your religion to Mormon.... pick up another wife (just for house cleaning purposes, of course), and presto..... you qualify for another parking space. See, I am still trying to look out for you my friend.

 

NO Turbo or V8. The only engine conversion I would use in my Crossfire is a Wankel. They stopped development so none for me. gary

J/K ya know

 

"Toly" Arutinoff, an infamous ecletic racer, racetrack owner, exotic car collector, and a friend of mine from the 50's built one of these for his 55 Studebaker Speedster V8. Total failure. So he waited till Studebaker built the Packard Hawk with the Mc Culloch supercharger and stuffed one of those in. Went like snot, stopped like crap.

 

A bit more power, 6 speed manual, lighter car so less work for the engine... Sounds like a good thing! And then the reliablity will be there for every day use for years to come!

 

Newer v6 out of the question? The 3.5 puts out as much power as the 430 v8. Wouldn't have that hollow rumble of the 8 but I imagine the e35 at 7200rpm would sound pretty mean.

 

Well, there's no replacement for displacement! But at the same time, I think with a 4.3 you'll end up wanting more. Except for the cost of the donor engine, the swap cost should be more or less equal between the options. For that reason you have to be brutally honest with yourself as to your final goal. Power? Image? Uniqueness? Chic cheap? If I was going to do a V8 swap I'd lean toward the baddest thing that would fit. I certainly won't judge no matter the final choice. Some of us older guys learned swap lessons the hard way. Just be sure of the final goal and if you don't have one don't do it. It's a huge job and it's the little details that will make or ruin the car for you. I'm actually loving what Chuck Norris is doing. A high boost turbo 4 banger. If your thinking engine swap, why not consider a ricer 4? (rice has no flavor, but it can be fast) I'm rambling but I hope it gets you thinking if your serious.

Almost worth doing just for that V8 sound!

 

1. do the 500 engine and keep the rowboat trans
2. do the srt-6 conversion with rudy and keep the rowboat trans
3. 13dog im not slo in the twistys im careful!( no wait i am slow. something about turns they really should straighten them out!)

430 isnt what you want

 

We will just stay in our SRT section....

 

Thanks for all the responses fellas.

Beaner is thinking on the same wavelength that I am... But Les and Steve are probably 100% right in the fact that once everything got buttoned back up together, I'd wish I had the extra displacement.

Looks like I'll be bean-counting soon. As in, totaling up the costs for all reasonable mods on the 320 motor, versus the initial bite I'd have to chew for the V-8 swap. It'll be way cheaper to keep the six, but the room for growth gets massive with the 8.

And no Gary, I didn't get much done after lunch ... slow day at the office

 

I know Rudy and Paul have a couple extra SRT-6 motors sitting around. I'd bet they're give you a hell of deal on the install. That way you get to keep your manual transmission, white exterior, AND no more parking spaces required.

If I had the extra cash, I was seriously considering looking for a good XF NA with a stick to put an SRT-6 motor in it. I really miss my stick shift.

 

I drive a stick shift everyday for work...glad I can relax in my little auto stick...besides, the future will do away with the clutch...it's already starting to happen in most sports cars today, and is now entering the trucking arena...not a fan in trucking, but it is coming...'puters rule...lol

 

Since I have a "lesser" V8, I thought I should chime in. The 430 engine is dirt cheap but you probably wouldn't be happy with the gain in the long run. The C43 is a great engine but you have to also change the oil pan and pick up to make it work in a Crossfire. There have been guys who have swapped 500 engines into their C43 and were suprised at the results. While the C43 and 500 engine have alomost identicle numbers, the 500 engine has a broader and flatter torque curve. I really believe the best lower cost V8 is the 500 engine. With the 500 engine there is no need to change transmissions. If you change transmissons to a SRT or V8 automatic you also have to change to a 3.07 diff. 500 engines are also dirt cheap and better suited to adding boost latter if you want to. As far as being challenged 0-60 or stop light action, you will have no trouble competing with a 500 engine matched to low Crossfire n/a gearing in the trans and 3.27 rear. the weakness of the 500 engine is in top end. Adding bosst latter wen you can afford it will fix that problem. A 500 engine with a Atwood supercharger will yeild 55K performance while a turbo will surpass a 55K either way you end up with a very fast car. My kill list with my bone stock 500 engine includes Mustangs, SS Camero's, BMW's, Hemi Challenger, S65, and a Bentley Continental GT. To put a 500 engine in a Crossfire, all you need is:

Parts

500 engine (with front sump oil pan), engine harness and donor ECU, All accesories from V6 can be used
C43. C55, CLK500 exhaust manifolds
C43 fan, shroud, and upper radiator hose
12 inch pusher electric fan

Modifed Orignal Parts

cable from starter to alternator get lengthened 5 inches
A/c hose to condensor get shortened 4 inches
Stock head pipes get tweaked at muffler shop to bolt to C43 manifolds and O2 bungs welded in.

Electronics

Donor ECU get unlocked and programmed to the car
a starter button is added

 

Bob, couldn't Rudy set you up so you dont need the starter button since he has it working on the 55K???

 

Who would not want a second Crossfire?

 

The 55K ECU is the only V8 ECU we have found that allows you to switch from the infrared key/CAN to the older style key/dedicated cuircut that the Crossfire uses. Rudy has been looking at this but he probably won't be able to find a sulution until he n/a V8 conversion to play with. This is why I am iterested boosting my engine with either a tubo or a s/c and running the 55K ECU.

 

I have to finish the two I have, but this winter, the search will be on for a roadster to convert. First the donor car, then save for the right engine/tranny. If, I take on this project, it will be a race car. It will be an all out go fast, bare bones toy. I love the two I have and wouldn't want to change anything on them, but, an all out project, kind of like JIM's, would be fun. Let's just hope my health and work keeps going like it is. That way I can justify it...I know Rudy is tired from the last one, but maybe we can entice him with the right engine/tranny combo. No, stick shifts, as I was a B&M auto front runner in 1973, and haven't looked back but a few times since, lol. But, the paddle shift, now, I have to have one of them. Rudy is aware of the engine I prefer/ tranny is optional..5 or 7...doesn't matter...it's just a dream right now, but, with a little luck...it can be done. I will have to lean on my old salvage yard friend, but I think Benny would get a kick out of what Rudy is building. Benny has been in the salvage business for many years and is into off-shore type boats. So big engines isn't new to him. And we are going big. 2012 project for sure. It even has the right numbers....lol

 

Check into Southern Hot Rod. They build full race MB 722.6 transmissions. Not sure if they are buidling the seven speed. Race car? How about a blown 6.3? A tubbed four link set up in the rear?
