Cam recommendations for ls2 with ls3 heads l76 intake Hey everyone,
I'm swapping a 2005 gto ls2 with t56 into a 93 rx7(2800lbs) and I'm trying to pick out a cam to match a set of stock ls3 heads and a ported l76 intake manifold I'm bolting on. I'm looking for 470-480 rwhp on a dynojet with the mazda 4.10 rear end. I'm wanting pretty good driveablilty, a little bucking is ok but minimal , and the car will mostly be a street car with occasional autox and roadracing mixed in. Here are all the mods I'm doing to the engine.
stock 2005 gto ls2
2005 gto t56 with spec lightweight clutch and flywheel
milled 11:1 stock ls3 heads with patriot extreme dual springs/ti retainers
hardened pushrods
ported l76 intake manifold and aftermarket cable t-body(probably a 92 or 95mm)
1 7/8" long tube headers Y'd into 4" single exhaust no cats
99+ fbody m6 ls1 ecu
factory mazda 4.10 rear end
stock ls2 maf
single roller chain and melling high pressure oil pump
stock water pump
Underdrive pulley(any recommendations?)
I've searched around quite a bit but results are all over the place with cam selection for this combo. Here are some that I have found, which is best(these or other recommendations) for a 470-480hp goal with good streetability?
patrick G thread for a road race f body that wanted big power band, made 460rwhp thru cats. Not quite 470hp, would a bigger cam see more? going bigger doesn't seem better on the ls3 heads
223/231 .610/.617 113+4 comp lsl lobe
spinmonster from the corvette forum picked out a cam that seemed really nice and made 474 on this vette with 4.10 rear.
xer comp cams lobe 228/232 .588/.595 114+2 lsa he also said 226/232 114 would do nicely, anyone know what that made?
Texas speed recommended a 228r cam 228/228 .588/.588 112lsa for powerband with road racing, and 229/236 112 lsa for more peak numbers. I have read that the ls3 heads like 8-10 degrees of seperation(like 221/229 or 221/231) and bigger isn't always better, so would the 229/236 not really fit these heads well on a 364ci?
I'm just trying to find the best cam for my setup, and will probably end up getting patrick g to spec me one, but I wanted to get a good idea of what works and doesn't before I go asking. I'm sure there is an off the shelf cam that will get real close.
Please input!
