E1839P cam ls1
Im about to purchase a cam and not sure if i should go with the E-1839-P or BTR weekend warrior cam that only has .553 lift.
Has anyone tried the elgin cams or even the knock off ones from ebay? If so how much hp did you gain and did you have to change pushrods for the regrind with a different base circle?
Anyone ran one a stock tune? It'll drive to the tuner with a bigger cam like the stage 2 1840.
Reason for doing the cam is my balancer has aged rubber pretty sure it needs to be changed before it walks off
Should get the parts together this winter if not before spring time need to get a couple other parts assault racing balancer, pac 1218s and one piece pushrods.

BTW the cam was shipped from "elgin industries" straight to an amazon warehouse before being sent to me according to package labels. The cam does have the same core or part numbers on the rear of the cam as a comp cam someone was selling. Guessing its the core they use. The springs out sold either by michigan motorsports or other vendors on amazon. Im waiting on a 15$ a amazon 15$ gift card before ordering the springs and seals. The real reason im going in there is for a balancer swap but if you have enough coin it would be best to throw a decent cam in there as i do the labor myself. The cam has nice specs wish i had seen assault racing or kmj performance has a 30 spline lock-up converter 10.75 bolt pattern with 2400-2800 stahl that would have worked i believe with the corvette 4l60e for 230$. Its a daily driver mildy modded corvette heads/cam at the most.

Yes i got a real elgin cam from amazon for 260$ shipped i think it was 23x$ plus tax. E1839P. I got it in with stock size assault racing balancer but mine is an 99 auto 3.15 gear stock converter. Doesnt have the ls6 intake or 6 speed 3.42s made 349whp 351wtq 12.5 afr tuned to 6k shiftpoints. All i have is an oval air filter, tsp headers, stock 2.5" h pipe exhaust and the cam, tsp 7.4 pushrods. I got it dynotuned in march and confirmed afr and dyno numbers from a different shop dynojet. Amazon assured me it was real elgin not knock off or could be returned came in elgin box. I used stock pushrods to get it running then swapped some tsp 7.5 pushrods. I had a similar 98 z28 6 speed 3.42s hooker headers, ud pulley and smaller bullit cam 114lsa 218 or something i didnt have exact specs that made 375whp/375wtq i suspect some is lost thru the auto 3.15s and not having an ud pulley. The first is my old 98 z28 i had sold due to a family emergency im currently trying to sell the rebuilt title 99 corvette if i can get what i want for it to get another 6 speed fbody. My left arm snapped in a car wreck 2017 when i was 27 causing me to have to steer right handed so i had went the auto route last year.
I had to get 18x10.5 295/35/18 tires. I recently cleaned all the niteshade the previous owner had on the headlights.

Last summer right after i did the headers i realized the torque tube was trash and had to remove the headers again to rebuild the torque tube the first is headers only and 2nd two videos are tsp headers with the 1839 cam and stock corvette mufflers. I did put a volant oval 5123 air filter as i read the ziptie mod or open air filter added 15hp the oval tapered filter is out of the way of the open hood area. It is a stock ls1 99 dynotuned 12.5 afr and injectors 96% duty cycle.You can see the difference in just the 1839 cam swap from the first two videos. From 50 feet with the stock mufflers im not sure what type of exhaust a ctsv has stock i think it has a torque tube similar to the corvette maybe not you couldnt hear any exhaust noise. The tuner recommended leaving the auto shiftpoints stock 6krpm and 6200 rev limiter. I think theres more power as my smaller cammed 98 z28 6 speed to 6600 rpm may have ran faster 114-116mph with the 375whp/tq
