Want to know what the largest cam anyone has in there 5.3 and how it runs? I had one recommended to me that seemed a bit much for a street truck 234, 226, 112 lsa. Was wondering if a tr 224 would be better.

 

Your going to need a tune and a pretty high stall converter IMHO with that setup. That sounds like more of a strip cam. I think a custom grind is best suited for our trucks as there are soooo many variables (gearing, tire size, weight, etc...). Good luck.

 

Depending on what kind of drivability you want, I agree with Buckwheat, the 234/226 is top end horse power cam, the 224 on a 112 would certainly be a better choice... I did a 226/232 in a truck and made 390@ the wheels(manual transmission). Most trucks have a restrictive exhaust system so having the extra exhaust duration sure helps...

 

ispeed: what motor was in the truck and what else was done.
i have a 226/226 and it is ok but i will prob change it.

 

ispeed, you had a 226/232 cam in what truck with what motor and made 390??? had to be with a poweradder, or some kind of wicked 6.0 setup.

 

That is awesome hp at wheels, hopefully around what i am going to achieve.

 

was the hotrod magazine test truck i had up here awhile back had the dyno sheet and everything...it was basically stock 5.7liter with stock LS6 heads prescribedpower cam, asmheaders,factory cats,upd induction, dual chambered exhaust,six speed manual tranny, 3:73's, mechanical fans... all the truck stuff still on it... short wheel base i personally ran the 1/4 up in michigan at 14.15 @97mph with a 2.8 sixty foot time, 20 inch rubber didn't hook up well...

 

hey ISPEED, you still gonna tune my truck when i get all my parts in? you do have a wideband and a dyno to put it on right?

 

is that the test truck in the video that lit em up through 3 gears at the dealership?

 

Yes same truck as in burnout video, thing rev's fast!

454, sure i'll tune you up, if i start getting a bunch more truck customers I'll have to dig deep and give the car-puting guys more loot for unlimited versions of truck.
