Default K or VX cam in a NA B230F? (2010 bump)

My "NEW" 88 5 speed 240 DL is undergoing some mods/ fixes 149k miles good condition. I'm replacing tank pump (dead), E-fan, New hoses, belts, Bilstein HD's with IPD springs, general tune-up 2.25 inch SS exhaust ( fabricating that).

I have a VX and a K-cam. It's mostly a Baby mobile but the stock M cam is horrid. No power
anywhere. the VX seems to have much better mid and top about the same down low. ( have this cam in my Lotus replica.) I have a K-cam on the shelf that is destined for the Votus
but it will need MS&S to run the best.

So VX or K in the 240 5speed? Mileage is a consideration as well.

I'm enjoying the VX in my '91 245 w/LH 3.1.
The 88 with 2.2 has potential advantages over the 2.4 and 3.1 since you can adjust idle and ignition timing to run a lumpy cam like the K cam, which is a more aggressive cam then the VX. I run the VX at 5 deg advanced, but the K cam won't recover the low end like the VX when you advance the cam. Also if you haven't already committed, get a 2 1/2" exhaust, not 2.25, and open it up to the Y pipe. If you don't do this you will not get nearly the low rpm torque or flow from what the VX or K cam is capable of.

I haven't done the exhaust yet, I have more 2.5 " stuff in any case. I was going to cut the
downpipe just after the Y and flare it to the exhaust. I have a 2.5 " free flow cat sitting around
and a good bit of 304 and 321 mandrel bends. ( left from many projects)
Thanks for the ups on the pipe diameter. I'm leaning toward the VX on the grandpa car

Here is said lotus replica. Donor was an 86 245, I traded an M47 for the M46 since it weighs
a full 50 lbs less. I now have a VIN # and it will be fully street legal soon. I've done a bit more
work since the last pictures.

VX will be an improvement up top without a noticable drop in low end. I drove it for a few years in my '87 w/ M47. When I switched to the K, I could feel the 'dead' bottom end and it definitely came alive in the 3-3.5k range. With MS&S, the K was flat torque from about 1900-4700 and it felt that way driving it.

It's about 20-25lb. I weighed an iron case M46 w/bell housing at 105lb and an M47 is around 80lb w/bell housing. Definitely enough to feel, and for me, it puts the M46 into the 'heavy' category while the M47 feels 'light'.

Just looked at some notes. I weighed the M47 at 77 Lbs with Bell housing no shifter.
the M46 was 110lbs with shifter and bell housing. So it was really only ~30lbs by my scales
I must have rounded up...

M46 = obese turd.

The K is the way to go. The VX will make more down low but we don't need to lug out little 4 cylinders around all the time.

The VX was part of the genuine Volvo Tuning Kit for that Motor, so go VX ;)

Dunno, you're without a turbo...

so whichever gives you better low end power is what I'd go for because up top you may not even notice that much of a difference between the two.

If you use the K cam, I wouldbe interested in buying the VX cam from you, if it is in good condition. I have $ in hand, if price is reasonable.

The K cam was OEM in Volvo's, no aftermarket, so why not?

By the numbers the K cam is still mild. VX is about smack in between the M and K
I decided the K will go in the Lotus replica where bottom end really isn't an issue
(1375 lbs). I'm going to do Megasquirt this winter, it's should make a BIG change
with the K cam.

Even the NA cars are very restricted by the crappy intake snorkle and cold air flapper.
I removed the flapper and and running cold air to both inputs(removed the 1.5 inch snorkle)
that's about three times the cross section. Stock header is good but the exhaust is crap
and probably saps 5-10 hp over a decent system.
Decent cam, good exhaust less intake restriction. 20% gain?? not bad, still not my
Alfa 164 0-60 in 6.8 over 148mph GPS. Need a lot of turbo in a 240 for that.

164 died an untimely death(accident). The 240 is a rather pedestrian replacement but I do
have a soft spot for 140's and 240's

K is the answer. Ran one in an '85 245DL for a few months. Exhaust note became a bit more aggressive, even with the stock exhaust. Idle was a little more lumpy. Did have to retard the ignition timing to about 8 degrees, since it'd ping violently above that, even with the knock sensor. Felt a bit weaker in the low end, but, once you hit about 1900-2000, the car accelerated quite nicely. Not Turbo fast, but noticeable. Only thing quicker that I've driven, K cam-wise and n/a, was an actual B23E with the 405 head. Had one of those in my old '81 242DL.

If I could get my hands on a K I'd go for it. With MS, LH2.4 you can advance the timing enough to get rid of the 'dead' bottom end. I had a K-cam in a previous brick (744, LH2.4, E85, automatic). Liked it a lot, did have quite an agressive timing map.

Would the VX be a good Cam for a Plus T or would the IPD Turbo cam be a much better Choice?

IPD Turbo cam for turbo car, or run a D or K.

So, were I to use a T-cam in my non-turbo 940 automatic, would that be best in your opinion, guys? It seems as if the low down torque it would provide would be a good match to it were I to work a few intake tricks and the new exhaust is on the way: freer flowing muffler, no resonator and a fresh cat. I'm sort of a newbie to this and am just a bit unsure of how the install would work with the current engine's timing.

Any Volvo stock cam would be better than T, If you like revving a bit K- is the preferable it performs best at midrange an high end you loose a bit below 1800 rpm, A or VX performs better in very low end and is "almost" comparable in midrange to K.

'T'-cams are garbage in NA motors.... and not really great in a stock turbo motor. I found the 'A' to have a much nicer powerband in both turbo and NA DD's.

Ah, I know of the VX cam from IPD. But, how directly does the A cam compare and where do you get a hold of one in the States?
