Big sale on Summit Racing Pro Ls cams and valvetrain parts
#21
Got my 8706 yesterday. My block and heads go to the machine shop next week to be cleaned and checked before I slap it back together. I can’t wait. And thanks for the hat! It’s been a minute since I got a new Summit hat.

A lot of that boils down to what you're doing with it and the behavior you're looking for. Can you give us some ideas on that, the vehicle and the drivetrain combination?

Summit, would I be better off with your stage 1 Hi lift truck swap cam and no bigger than a trailblazer converter in my heavy suburban? I also have a comp cams 212/218 115lsa (pn#54-424-11) I can try. All I care about is 1/4 miles et's with this suburban it doesn't have to have a super choppy idle if it isn't necessary for performance but it will add long tube headers and x pipe with free flowing mufflers with duals out the back like a proper muscle truck should to maximize tourqe. My transmission guy can probably let my little 1500 4x4 spec 4L60e shift as high as it needs too if that helps et's, I shift the little BTR cam at 6800 off the first bounce of the rev limiter in my Z28 so I don't see why we can't do that with it in the burban (or higher if needed!) even though the factory tach only goes to 6k

Spend your money on getting it moving and plated first, see how it goes and then you can worry about upgrading the valve timing. Just my humble opinion. Take it or leave it

Get it running and driving reliably with the stock components first Or Your going to have a lot of extra headaches. You don't just get a cam for a engine (do you even have it yet?) and your dream transmission that you don't have just setting there with an unknown destination lol

If you want to build a car around a camshaft that is fine, though the most logical thing to do would be to build the car first and then see what kind of cam it needs.

Hey G thanks for stopping by. Tell me, what do you think about the asymmetrical .545 liftish lobes on my new 8714? I really do believe summit that it's the meanest truck cam, I hope they don't break my heart. will it gain 60ft and up over my BTR stage III do you think? Is a couple tenths all the way down too much to dream about?

I'm super pumped to try this 8714 in my otherwise stock, blue sprung 5.7 Ls1 with stock ls6 intake and pacesetter 1-3/4" long tubes. If summit has a better cam for what I want (Max et's with a/c and ls6 springs) that will drop in and work with my setup maybe they would exchange cams with me, as I have to wait a bit to install it anyway, But I think I made a pretty good choice with the 226/230 112+4. I'm Sure it won't be too radical at im guessing about a 850-900 target idle with my cutout closed to a magnaflow 12267 muffler and stock black rectangle Z28 spouts.

I've finally gotten finished installing and tuning that new summit 8714 in the LS1 in my 2002 Z28 A4. The car sounds a lot meaner now and pulls even harder above 4k rpm than it did before. I look forward to seeing gains at the track as well!

Good stuff, when you get a chance...please write a review...make sure you mention the pizza delivery part and a time slip! Maybe even a picture of it leaving with the delivery sign strapped to the top of the car!

Guys my setup already runs high elevens (I have a thread about low lift truck cams in the ll second club) I simply swapped out my cams, BTR stage III truck for the summit 8714. I will get into more detail when I update that thread once I get some track results. I can tell you already that the idle is much louder and meaner and that the car feels stronger at high rpm which is exactly what I wanted to take advantage of my tci 242932 and 3.73 gears.
I'm Sure I have one of the quickest licensed and legal naturaly aspirated pizza delivery vehicles on the road, summit please help me organize a fair race and then give me an awesome prize when I win it lol, I have a blast delivering for Papa John's in my Z28 even when we have a St Louis snow, it never misses a beat!
