Hey I can see that the cams are on sale , but the the pushrods are still regular price Can you clarify this , very confusing. Called Summit talked to 2 different reps for half hour, they said they are not on Sale !

I wish the matching springs for the stage 2 turbo cam would go on sale at the same time. Hopefully soon

Summitracing

Hello, sorry for the confusion. We checked and although the list of parts is long...the HDR pushrods are indeed not on that list. A bit of good news is the $20 of $200 and $50 off $500 and $100 off $1000 just started and may run for a few days. If you run into any errors, please PM us and we'll get it figured out.

Summitracing

Hey there, it's a surprise that just went up yesterday but there's a 20% off $200. So a set of new like the new TFS-2500286P Nanopeened Dual Platimums would come in at about $200 even!

Those are the ones in my cart along with everything else.

I just ordered a pro LS 8714 stage 4 "truck" cam to replace the btr stage III "truck" cam in my 02' Z28 earlier today, thanks summit!!

Summitracing

Thanks for your patronage folks!

I've gone as quickly as 11.87@115mph at full weight with my basically stock all original bolt on car with just nittos on the stock 16" wheels with the older (date on the cam box is April 2015 haha) 113lsa version btr stage III truck cam. I race at gateway in East STL and I sometimes deliver pizza on the weekends with my 2002 Z28 so it must have truck-like reliability. I'm convinced that my trusty (with proper tuning of course) older model Tci 242932 converter and 3.73 gears (summit girdled original 10-bolt also lol) wouldn't mind the added duration and overlap of the 8714 and your sale was too good for me to pass on, even on a father of two boys budget!!

My only real dilemma caused by your sale is that I'm a guy that only changes one thing at a time on my car and then goes and sees if it's better and the car has reached the point where I think I need to disconnect the front sway bar at the track but I have never done so before. I'm really excited to put the bigger cam in that I just ordered from you guys but I really think I should figure out the front sway bar thing first. What should I do?

Summitracing

Well, if you and the boys can get to the track before the cam install, that would be a good idea. BUT, if you want to stab the cam in it and run with the bar hooked and unhooked, it should give you a pretty good idea of what it would have done with the old cam.

Thanks for throwing in a hat too haha, I just saw that. I still think the btr stage III truck is a useful cam as well. I'm hoping it will improve the performance of our 2004 L59 4x4 suburban with GT5 and G80 thankfully picked by the previous owner.

I just went outside and grabbed my new 8714 off my doorstep!!! My new bumpstick came very nicely packaged inside a cusioned bigger box and it looks great! I'm going to have a hard time waiting to install this! Thanks again summit!!!

Summitracing

Your very welcome and Thank You! Keep us apprised of your build and results!

Dear summit, on my new camshaft card the figures for .006 show the cam installed at a 109 intake center line but the figures for 0.050 have it at a 108 ICL as per the indicated +4 advance.

Is there some kind of asymmetrical thing going on with the cam lobes or are you just trying to tell me that my particular cam had 3.5 degrees of advance ground in it instead of the advertised 4?

stockA4

I'm asking why are the events at 0.006 figured for a 109 intake center line instead of the advertised 108

Summitracing

You got it. The lobes are asymmetrical, but on top of that all those little tenths of degrees round up differently at .050. So yes we’ve ground 4 degrees of advance into it so you can install dot to.dot and get the valve events we’ve targeted.

stockA4

That's awesome to hear! though, I would have accepted one on a 111icl lol, I wasn't going to ask at the price I paid, such quality!

Debating between the Ghost cam (SUM-8715) and the Stage 2 cam (SUM-8706). Either cam will be matched with PAC 1219 springs. The build is a 5.3 and the turbo is a 7875. Would it make sense to start with the Stage 2 cam to leave room to grow on power if I ever want to push the engine further.

stockA4

Stage 1 would likely be plenty of cam for you with a 5.3L imo
