Why not yank the heads and have them ported?What kind of #s are you putting down with the setup you have now?

that is nice power you made!! i would look into just adding those heads with that cam and then spray it and see how you like it. if anything, you can always end up swapping the cam.

From what I know about the two cams; going to the MS4 you would probably lose alot of your low end and have to spin it much much higher, but your 4.10 gears would help with that.

IMO I would sell the PRC heads and take that money and have your 243's ported by TEA but thats just me. I think you would make alot more power the the TEA 243's.

JaSSon went high 10's with ported 243's and the TR230 cam.

I am putting in the TR230 cam w/ TEA ported 5.3 1.5 heads w/ LS6 intake, L/T headers, then going to spray 100 shot on top of that.

Keep us updated.

i guess i'd like to know why you want to change cams?

is this a drag only car?

porting the heads would be a great way to boost power

Was this on a mustang or dynojet.

Are you wanting to change to the MS4 because it's the "big & cool" cam to have on the internet, or because you've researched the combo and know it's the right choice for your application?

Im not usually a fan of big cams, not at all. My last cam was a 226/230 .609/.588 and I could not have been happier. This time I called Predator Z to spec me a cam. He recommended I go with something abit larger to suite my stall, gear and frequent drag strip use. He recommended a 240/244. So not all big cams are a bad thing, but ide likelly talk to someone like Pat G or Predator and see what they had to say.

thanks alot guys . i just dont like the reverse split cam i dont think it pulls as hard as it should. i just want more power. a guy had a set of prc 2.5 5.3 heads and ms4 cam for i thot maybe it would be a good route i want to bump the compression up i think its a smart way of making more power seeing i want to keep the 346 in there it only has 4,000 miles tops on it

Sounds to me like your ready for a drag strip cam.

I made the swap from a TR230 to the MS4 with stock heads. The TR230 pulled harder to about 5000 RPM when the MS4 would start to come on strong. For a street car that sees some track time my vote is for the TR230, but for a track only car I would go MS4(but not with stock heads). The heads and compression ratio will play a huge role in the performance you see from the large cam. If you have a stock shortblock you will need to cut valve reliefs in the pistons to get the CR high enough, mill the heads to 57/58cc and run an 0.040 thick gasket. If you don't want to cut the pistons then stick with the TR230 and have the LS6 heads worked over as stated above. I can promise you with stock compression cam vs. cam my TR230 walked all over the MS4 and was much more fun to drive. It's all in the combination.

I would go with ported heads instead of cam swap because you are DD this car.

My car is not a DD but I really like the powerband it has; no loss and start pulling from 3000-6400. I want the high hp numbers too, but I'm not sure a big *** cam is gonna give me the nice powerband I'm always into;2000-5000...Plus I made some road trip with my car and it likes to ride the highway at 1800-2200 in 6th without any bugs. Plus it loves the 150shot LOL. My car has a forged 347 though.

But I have stock 3:42 and wont go any bigger than 3:73 because its a street/weekend warrior car.

Tell you what I would do........If you want to sell the TR230 shoot me a PM.

Why not get the 243's milled and ported and be ahead of the game?

Then put the nitrous on top of that and see how you like it.

My opinion.

thanks so much guys i had the 243 tr230 fast 90 90 pacesetters , underdriver pully and qtp y pipe . when i sprayed it kicked in at 3,000 and i had to stop at 3800 rpm for the steam and i was at 524fpt with a 100 shot it blew a head gasket and i found that small coolant leak i had every now and thanks to the nitrous but first of the year i should have it back together and am heading back down to the magic man bluecat for round two , big thumbs up for him not making me clean up the vomit my car left behind in his garage.
