what r the bigest cams (highest lift, most duration on a 112 lsa) u guys have stuck in ur f bodies with 241 heads without cutting the pistons or addind thicker gaskets or any of that crap just stickin it in and going. these can be street cars or drag cars just interested in what the motors can take before there are clearence issues

 

+1, would also like to know this. W/ AFR 205s assuming .03 cometic.

 

TREX and MS4 are good examples. Chumma created a custom cam for a guy on here that fit without flycutting and its bigger than both the Ms4 or the TREX. Its like 245/250.

 

+1 for T-rex and MS4.

If I'm not mistaking I think they were both designed to be used with stock heads with no flycutting.

 

I have 241s with the MS4

 

G5X4 is up there.. it will fit without flycutting.

 

TREX V2 is about as big as you can go with stock heads, and have an effective power band. TREX was designed to be used with stock heads and does very well, but its also excellent with ported heads if you ever decide to do a head swap.

 

im running a 234/240 .627 .641 112lsa with 853 heads that were milled .010 for trueing with no flycutting

 

that, is a good amount of lift. thanks guys

 

Will the T-Rex work with stock 243 heads?

 

i dont think so i think that the valves are just a lil bigger then the 241 heads.

 

It should fit the stock unmilled 243's just the same as 853's and 241s. The valve size is the same, chamber size is smaller but that won't affect the PtoV clearance. Pretty much all these cams listed clear, but most don't clear by safe margins. Honestly I don't understand the big cam craze around here.

 

i never said i wanted one and neither did anyone else on this thread i simply stated in the first post i wanted to know just to know, for the technical stand point.

 

244/248 .612/.615 @ 114+2 stock 346 although this is with 317 heads, I am in the process of changing heads though

 

yes it will i ran this set up hard till i bought my 408.

 

For those with confusion akin to BigKap94z here is an answer: then you too can walk away from a 510 hp 2007 Lamborghini Gallardo Spyder on the highway

My very good friend bought one new 4 months ago and I walk him N A S T Y every week we roll (on motor BTW)

With the proper combination of parts and proper driving, a good big-cam/heads set-up can be devastating

 

i know this is kinda a old topic but, will the G5x4 clear stock ls6 heads?

 

Yes (unmilled heads stock mls gasket)

 

I have ran an MS4 in a stock long block with 241's and 243's and on a stock 07 LS2 also with 243's with no issues to date
