Yessir sometimes less is more. The man-child in me wanted an agressive cam and all the trimmings to extract the most from my trailblazer 5 3. But then the more mature me realized my wife will drive this sometimes and I drive 40 mi to work and to dial it back a little. BTR tq cam with afm delete, all new vlave train from trays to springs to lifters and longtube headers and I'm happy. Still chops a little and its been tuned to perfection and I even picked up mpg along with better drivability and I look like a champ to my wife. That wouldn't have been whaf happened had I went with all the extreme stuff like I used to. Guess I'm getting older and softer.

Thank you 337 Speed for taking the time to produce this video. This is why I love KZbin - knowledge transfer from experienced professionals. I recently had my 2018 Corvette Grand Sport cammed with headers, cold air intake, no cat x-pipe, and a mellow exhaust. I love the performance and sound, but I'm not too fond of it when I come to a slow stop or let off of the brake from a complete stop to rolling - my Vette jolts and jerks a lot. It's like trying to get a wild horse to stay still. Is this an unintended consequence of a cam swap?

@TheShotgunGGjr2 жыл бұрын
Another aspect to think about is what is the purpose of the vehicle? You can build a truck to be as fast as a corvette or even faster. Low end cams are only good for daily’s and grocery getters. A big duration cam can still be handled if built right in a 5.3 of course you can only go so big. I’ve seen people put 235/240 cams in a 5.3 with a 4000 stall and a shot of nitrous on 3.73 rear end and it’s a nasty setup of course it’s all preference for NA or a boosted setup.
@B2sdad5123 жыл бұрын
Great video Sir, very well said. My cam swap came because of a lifter failure. So I went with complete DOD Delete. I also did LT Headers and 3 inch catback while I was there. Truck was tuned and drives great, for the most part. Its a slug down low, which drives me crazy... after its gets up to speed its fine. My mechanic never mentioned anything about a higher stall converter. Now I really need to find one that is well suited for daily driving. Vehicle is an 07 Suburban, she's a big girl, but I like her.

Hey hey, hell yeah bro I have an 08 yukon denali too but the sport version not the XL and a great inexpensive exhaust you should look into is the MBRP installer series I actually had one for your truck and gave it to my nephew and let him cut it up to fit a different vehicle because when I ordered mine they had sent me the XL at first then refunded the money and I was stuck with their exhaust still and they never bothered to send the correct exhaust kit smh so I ended up ordering it elsewhere and it came overnight and cost less but they're super easy to bolt on I did However have mine welded and I do recommend going with the black coated if you live in salt and snow area once I bolted that thing on I was like the last piece to a puzzle that I'd been missing all along lol sounds great and doesn't bother the neighbors too too bad when I remote start at 6am 🤣🤷♂️ once I cam spaw it things will be different I'm sure but so far all I've done is the K&N air filter, exhaust and the flashpaq F5 handheld tuner and for a big heavy boat I'm roasting sports cars at the light and she really moves out of her own way!

Because of this manifold, I wanted the intake valve to close @ 42abdc. If I had a FAST I could close at 44, if I had a Super Victor - maybe 48 or 50. I wanted a cam with throttle response and street manners. 222/226 112 +1 with lift just under .600" to be easy on the valve tips and that soft camMotion ramp speed.

It's not like you can't stick another cam in it when it gets old are you discover it's not what you need, those people ain't going to listen when you tell him you're better off with a stage 1 for a 5.3 or a torque cam a stage 2 or a torque cam for a 6.0 whatever you do don't tell them about the truck Norris cam, cuz that way they can't outrun ya...p.s those mild cams spool faster ;-) and all cams are turbo cams 🎤
