Newer cam grinds (on 114LSA) to replace TR224 Current setup: '99 Firehawk M6, ARE S1 heads, TR 224 (112) cam, 918 valvesprings, stock retainers, LS6 intake manifold, Grots, 3" ORY, 4.10 rear. Right now it's putting down right around 400RWHP / 385 ft-#, but I think I'd like to try a new cam grind.
I'm looking for a grind with more duration, not necessarily any more lift, ground on a 114LSA for an easy idle and putting around town (daily driver). I've been eyeballing the MMS 229 v2.1, but I've also seen a newer MMS 229 v3.0, also ground on a 114LSA. I can get MTI's X1 on a 114, and TSP has an interesting single-pattern 228 on XE-R lobes. I'm partial to a single pattern grind and open to new ideas. Can anyone give me feedback on any of the above grinds or some ideas for something new? Thanks in advance.

Re: Newer cam grinds (on 114LSA) to replace TR224 The 114 won't help hardly at all for drivability. I'd keep the 112, and switch to a reverse split pattern. They seem to help the drivability side a little. The X1 does just fine for street duty, and I'm sure the other grinds that you mentioned will too.

Re: Newer cam grinds (on 114LSA) to replace TR224 Will the 114 LSA help idle quality considerably over the 112? These grinds have been around for quite a while... is there anything new I should check into? I'll most likely find a grind I'm interested in and call Comp to reproduce that for me.

Re: Newer cam grinds (on 114LSA) to replace TR224 Do any of the tuner shops offer that grind right now? I take it that's on XE lobes... would you happen to have a grind number on that cam from Comp?
Re: Newer cam grinds (on 114LSA) to replace TR224 You could try a 228/228 114+4 Comp XE profile. The lift is about .566ish. If you want a higher lift, try that TSP 228/228. Running 4 deg of advance is a good idea when running cams w/ duration this high, especially on the street.
Re: Newer cam grinds (on 114LSA) to replace TR224 The mms would be a good choice. the problem with not running higher lift is the lobe rates slow down and that makes the idle worse. I now have an XE-R 228/228 114 +4 and it idles very smoothly at 900 rpm with just a hint of lope. You could consider the TR 320/224 on a 112. TR uses fast ramps but with slightly lower lift than the XE-R.

Re: Newer cam grinds (on 114LSA) to replace TR224 Thanks for the advice. I also have to consider a couple other requirements:
-Reliability and valve spring compatibility. I'll want to keep the cam and springs in for at least a year, 20K miles or more without worry of having to change springs on intervals.
-I'm starting to get into road racing, so my setup is changing. I'll go with a 3.73 rearend ratio and I'll need a healthy amount of torque from 3,000RPM and up to muscle the heavy car out of corner exits.

Re: Newer cam grinds (on 114LSA) to replace TR224 My 230/230 112LSA XE-R cam with my ARE heads and other mods makes great power (peaks at 6300rpm) and is pretty smooth and driveable with a 950rpm idle. (See sig for performance numbers)
I also passed roller emissions with this cam and the good tuning.
Cheers,
Chris

Re: Newer cam grinds (on 114LSA) to replace TR224 I'd stick with a 114ls cam myself, I've run from 110-114 and 114 is definatly nicer on the street!
I've twiced used the MMS 229v2.1, once in a stock shortblock and another with my 396. Great street/strip cam IMHO.

Re: Newer cam grinds (on 114LSA) to replace TR224
Sorry to steal the thread, but how do you set up a 114 LSA cam with +4 degrees? Do you need a special timing chain or pulley?

Re: Newer cam grinds (on 114LSA) to replace TR224 Bringing this thread back to the top... still very interested in the MMS grinds. How many degrees of advance is ground into the MMS 229 and what's different on the new 3.0 grind?

I'm running this exact cam myself in a 346, although i'm running a 110 LSA. I have stock idle speed, and it idles like a wimp IMO. Not near enough idle for me, but for others it may be enough. Not sure if it'll pass emissions or not, I dont have to worry about that. Definately driveable on the street.
