i'm building an 82 c10 RCSB lowered 6/8ish with a 5.3/4l60e. i've been trying to decide which cam is best for me, and i've narrowed it down to three. i don't want to run a stall bigger than 3200. the truck has headers, fully custom catless exhaust, all emissions deleted, CAI, efans, shift kit, and vette servo, and 4.10s. the truck is light, like 3800 lbs max. i just spoke to aaron at texas-speed on the phone and told him what i wanted out of what i've got, and told him i was thinking the tsp220 and he said i was right on track and that cam was would be perfect with a 3200 stall, while still being very driveable. this truck is my first car, and will be my daily driver.

i was thinking the texas-speed cam package with a tsp220r, PAC1218 springs and 7.4 hardened pushrods. to me the lift seems kinda high.

next choice, in no particular order, the thunderracing 220 cam package, with comp 918 springs(which i've heard were prone to failure), and hardened 7.4 pushrods. this was my first choice, because of the great price, but if the springs are trash, the deal isn't so good.

and the same package except with a thunder racing tr224.

i was thinking the tsp220r would be a good midpoint between the tr220 and tr224, since it has the shorter duration with the higher lift.

what about LSA, which would be best for me? 112 or 114.

i go to a school where all the kids are brats, and think that their v6 2010 camaros are the fastest thing in the world. noone will see it coming when an 82 c10 will hang with a 2010 camaro ss, which i think if i can make 350hp/350tq at the wheels(camaro makes 400hp/410tq at the crank) and weigh 3800(same as camaro). thanks

 

i would go with the tsp package. you're splitting hairs over the difference in 220 cams, but the pac springs are better and tsp has great deals on their full cam packages. most around here stick to a 112 LSA/

 

haha i know but i want to make the best decision and a year later go "i'm really glad this is the cam i got" anyone have any tsp220r or tr224 dyno charts?

 

I pretty much have the same setup but in a 68 c10 and i have decided on the tsp 220 on a 112.

 

sweet man, how soon do u think u will have th cam? i'd sorta like to know how they pull with a 5.3 in a lighter truck. what stall do you think youll run?

 

Can't go wrong with either the TR220 or TSP220.

Is this cam going in a NBS 5.3L or the NNBS (gmt 900) 5.3L?

The newer 5.3L's have the better flowing heads and intake manifold so 350hp to the wheels is doable. If you have an older 5.3L I would do some head work or new heads and get a TBSS or NBSS intake manifold.

TSP220 cam is a good cam for off the shelf, here is a idle clip of mine.

 

what he ^^^ said. in addition, either 220 cam sice you dont want to run more than a 3200 stall would be best in my opinion. both are very similar and proven. there was a tr220 with pushrods or springs (dont recall) int eh classifieds for like 250. that is a good deal there.

 

it's a nbs 2000 gmc 5.3l LM7. would i see more gains in performance with a nnbs intake manifold,tbss manifold, or an ls6 intake mainfold?

what about degreeing the cam? do i have to do it? or is it only if i want to advance or retard it?

another thing i guess i should mention is the engine has nearly 200k miles, i will be replacing the timing chain and sprockets, and possibly the oil pump. the engine will be out of the truck when i do all of this so it won't be as difficult.

 

In something that light I think I would go bigger then any of those, I really like my TSP220 but I really wish I went bigger
a tbss or nnbs intake is defanitly an improvement over your stock intake

 

the cam i would step up to is the tsp224r and it would probably be a dog with a 3200 converter, so i would have to go bigger. the thing is is that if i went bigger, my stall would have to be bigger, and this is my first car/daily driver and still want it to be driveable. another thing is that a circle d 278mm stall is only available in 3200 max, so if i had to get a bigger converter, i would have to spend more on a stall too...

i saw this cam in the vette section of texas speed, and it is exactly what i'm looking for, but it's not available in the camshaft package and idk if it will work in an LM7
