Biggest cam with stock Stall
Biggest cam with stock Stall I am looking for a cam that will make the best power with my stock stall in my 05 GTO. My setup will include an LQ4 shortblock, GTP stage 2 heads milled to give me 11.03:1 compression, Edelbrock Pro-Flo intake, 1 7/8 Kooks LTs, 3" catless exhaust through Magnaflow mufflers, 3.91 rear gears. Please don't tell me that changing the stall would be better or this or that....I KNOW!! I just don't want to do it. Any suggestions are appreciated.
236/238 .601/.605 113+3 should be about the limit
edit: This cam should be about all you can handle with the stock converter

Everything mentioned so far is still to big for a stock stall on any auto car. A 228 on a 114 or more lsa maybe...maybe. I'd say no bigger than a 220 on a 114. Look into a custom grind that would suit your need the best since you want to stay stock stall Pat G would give you a great cam spec that would be perfect for that set-up. One question if your going H/C/I anyways why not a stall converter seems kinda of waste to me IMO only. Why not a 2800 converter that would open the doors up to a lot more cams like 224s 228s and the likes and give you a very nice package with the CR you are planning to run and the heads and intake you'd like to use. Your gears suit a bigger duration cam anyways.

I would get the sawzall out and weld in some way to remove the exhaust so you can work on that thing. Not much sense in running a cam you don't want just because you dont want to mess with the exhaust to install a converter to make everything work in harmony. JMHO
Agreed, that's the largest we typically recommend for a stock convertor car as well. Any larger and it wants to push through the brakes and gets too sluggish.

Same driveability between the two, but about 7hp at the crank more from the XER lobes. I'd go .581" any day between the two, stock convertor or not.

I think a 224 is too big still but it could be made to work. I'd say a 220/220 at around 550/550 on a 114 with LS6 springs that would work great and be cheap. But still I'd go with a good 2800-3200 verter and a 228 or the new 224/227 from TR.
