Biggest cam with stock Stall

05JUDGE · 08-04-2009, 06:05 PM

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

Wow, that's a pretty big cam. Bigger than I was expecting anyone to recommend anyway.

i say no bigget than 228 on 112 lsa and that still might push through the 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.

Well because I had my exhaust fully welded, headers and all, I can't drop the tranny to swap one in. The only option I have is pulling the motor. WHich isn't a huge deal, but it's enough of a PITA that I don't really want to do it. I may break down and just get a good spec'd cam and get a stall. I just haven't made my decision yet. I am looking for my options right now.

if you went with anything over a 224 your car would run like a slug off the line.

bluehawk2 · 08-05-2009, 09:01 AM

I would hold off on the cam until I did the torque converter. that would give you better cam options.

rpturbo · 08-13-2009, 01:20 PM

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

224/224 .581/.581 cam or the Lenginfelter GT11 cam.

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.

still i think thats a tad bit much lift for a stock stall... the thunder tr224 on a 112 is about ok for the stock stall.. 224/224 563/563 112

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.

Fbodyjunkie06 · 08-13-2009, 06:50 PM

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.

davidws6 · 08-14-2009, 07:11 AM

I'd do the 224/224 .581 on a 114 LSA or even a 115 LSA

Should be fine with a stock TC. stock cubes.

muayyadf1 · 08-15-2009, 09:50 AM

I ran a 224 cam on my car without a converter with no issues. But when I put the converter my car ran much much better.

05JUDGE · 08-15-2009, 11:05 AM

I've been looking into the LPE GT11 cam. I've read some good stuff about it.

Gordon0652 · 08-15-2009, 08:04 PM

I did the MS4 with the stock converter for 100miles, then to a yank 3600 stall. Liked the aftermarket stall with the cam. Then 100 miles down the road engine went BANG!
