I'm going to be doing a cam swap and have already talked to stock48 about one of his cams but wanted to get some opinions on what you guys think. My set up Is pretty simple and all this is in a full weight 00 4600lb 2wd single cab

Stock lq4 longblock
Stock intake
80lb siemens
FTI 10.5" (stalls 3300ish)
EPP 232/240 115lsa
3.42's
T6 s475 1.32AR bracing kit

I'm currently on pump gas but I will be upgrading fuel system and running E85

The EPP cam didn't make any power down low and decent mid range. Aggressive on the tune I can only manage a 1.85 60" leaving on 4psi. I'm sure if my truck was lighter it was run alot better but I'm needing a good amount of torque to get this thing into boost fast.

You guys think I could actually gain MPH from swapping to a big 232/240 to a 215/215 112lsa or TU0 (216/216 113lsa) or tu1 (225/225 112lsa)

I do realize the more overlap you have the power your gonna make but there has to be a point to where there's just to much overlap and I think I surpassed that with the EPP cam in my heavy truck. What do you guys think about those cams?

I'm pretty set on an isky cam but I just want to get some opinions

look into the VTC-2 from VA Speed

That's a reverse split cam isn't it? I thought reverse split were good for twins. Bit I don't know much just what I read lol.

You should be making much more than 4psi leaving. Your tune is the problem, not the cam. Are you capable of making more boost out of the hole?


Then again, you're in a whole nother realm with a 4600lb vehicle. Still, there's little to no power to be had at 4psi. I dont care what cam you have its going to be lazy.

T6 96mm turbine and 1.32 AR + 232/240 + 3300 stall speed in a 4600lb truck is mostly the reason why it's such a slug out the hole. 4psi is all it will make thawing about 28-30* timing at it. I think a smaller c that makes alot of power down low and an 83mm turbine will make it a new truck.

I think the issue is the converter, it's not properly matched to that turbo.

A reverse grind with less duration will help keep the cr up and help tremendously with cylinder filling which is how boost is made the pressure has to come from somewhere to make the turbine move. So the sooner that happens and the more it happens the quicker harder and faster the turbo will spool.

I'd go with the TU1 or a similar custom reverse grind like the cam I am running. It's a 227/224 on a 114 and it makes great tq. Do you not have a two step on your transbrake? If so try this. Whatever rpm you have your t brake set at, say 3600rpm. Retard your timing 8-10* at that rpm(3600) so say you ran 24* up to 3200 drop it to 16* at 3600. This will move the combustion event out of the cylinder into the manifolds since your adding fuel and no timing the egt's will rise making the headers hotter and hotter till the combustion lights off in the crossover and headers. This will make it bang the 2 step chip really really hard and will bring on a lot of boost. I did this and it helped alot!

i used the va speed vtc3 cam with 6.0 with stock 317 heads and made 753whp on 16psi using a bw st80. it worked great with the 6.0
